INTRODUCTION

This document explains how your station works. Station operation, alarms, basic

troubleshooting, settings, and components are all explained in detail. It is the most important

part of your owners manual because it is the key to understanding what your station can do and

how to operate it properly. In addition, the answers to the most commonly asked questions about

the Gator can usually be found right here. Use the table of contents as a guide to finding what

you are interested in. Please read on! It will be worth the time you spend.

STATION OPERATION

Pressure/flow sequencing

This mode of operation for the station allows the pump to start on pressure and stop on a “no

flow” condition. The pressure sequencing setpoint is controlled by the low system pressure

switch located adjacent to the motor control panel. The low system pressure switch should be set

10 to 15 psi below system pressure. The flow sequencing setpoint is controlled by the flow

Bulletin 29-510 Page: 2 SyncroFlo Gator

switch located in the discharge manifold of the station. It should be adjusted to detect flow at 5

to 10 gpm.

Pressure sequencing should immediately start a pump if the system pressure drops enough to trip

the pressure switch. Once the pump has started, it is latched on until the system pressure is

satisfied, the flow switch detects a “no flow” condition and the minimum run timer for the pump

has expired. When the off conditions are met, the pump can then shut down following the

expiration of its stop delay. Flow sequencing (flow anticipation) will also start the pump. This

occurs if there is enough flow through the discharge manifold to cause the flow switch to open,

bringing the system out of a “no flow” condition. Again, once the pump has started, it is latched

on until the system pressure is satisfied, the flow switch detects a “no flow” condition and the

minimum run timer for the pump has expired.

Time clock start sequencing

This mode of operation is controlled by a time clock located on the face of the motor control

panel. It can be set to bring the pump on and turn it back off at the desired times. The time clock

is a 24 hour, 7 day clock and can be programmed to operate in a number of different time cycles.

See the time clock operators guide for further instructions on operating and programming the

time cycles.

Remote start sequencing

This mode of operation is controlled by a remote signal provided by a remote timer or an

irrigation controller. This mode can be used to bring the pump on and turn it back off at the

desired times, as with the time clock sequencing described in the section above.

NOTE: Please see the station data sheet for further clarification on the type of pump sequencing

and options provided with your station.

DOOR MOUNTED CONTROLS AND INDICATORS

Pump Selector Switch

This switch has a green lens, and is labeled “NO.1 PUMP”. This switch is also referred to as

“H-O-A” switches.

HAND: Use this position for temporary manual operation, or to test a pump. The station should

be supervised when pump is running “in hand", since all pump sequencing functions are

bypassed. The pump and the irrigation system is still protected by all alarms when the pump is

run “in hand". If the PLC fails, the pumps can still be run “in hand", but all pump sequencing

controls, and the alarms will not function.

OFF: Use this position when restarting the station, or when a pump is down for service

AUTO: Use this position for normal automatic operation of each pump and the station as a

whole. The PLC has full control over all pump operations in this position including: all pump

sequencing functions, and all alarms.

Run Light: The pump is indicated as running by a light which is inside its selector switch

handle.


Low system pressure alarm light

This light is red, and is labeled “LOW SYSTEM PRESSURE. This alarm detects low system

pressure in the discharge header with the low system pressure switch located adjacent to the

control panel. This alarm could be caused by any of the following:

1. Low system pressure switch setting too high.

2. Misadjusted main and/or bypass control valve settings.

3. Flow rate greater than station capacity (too many sprinklers on).

4. Low system pressure switch sensing line valved off or clogged.

5. Low system pressure switch failure.

6. Pump selector switch turned off.

7. Motor overload trip.

8. Motor starter coil or contact failure.

9. Main and/or bypass control valve failure.

10. Motor failure or reverse rotation.

11. Pump failure or loss of prime.

12. Pump check valve stuck closed or installed backwards.

13. A large break in the irrigation piping.

14. Low suction pressure, loss of prime, or supply water restriction.

The low system pressure alarm can only activate when the system pressure is low, the PLC has

already started or tried to start the pump, and no other alarms are activated. As soon as the low

system pressure switch senses low pressure at the station discharge, the “low system pressure”

alarm light will turn on. If the system pressure increases any time before the 5 minute delay

expires, the alarm light will turn off and the pump will continue to operate normally. If the

system pressure remains low for 5 minutes continuously, the pump will be stopped and the

alarm light will latch on.

To reset the alarm, push the station “reset” button. This alarm will always reset even if the

system pressure is still low.

NOTE: The low system pressure switch is also used to start the pump on stations with

pressure/flow sequencing. (See STATION OPERATION section for details on pump starting)

High system pressure alarm light (optional)

This light is red, and is labeled “HIGH SYSTEM PRESSURE. This alarm detects high system

pressure in the discharge header with the high system pressure switch located adjacent to the

control panel. This alarm could be caused by any of the following:

1. High system pressure switch setting too low.

2. Misadjusted main and/or bypass control valve settings.

3. Sudden decrease in flow rate to no flow.

4. Pressure control valve hung open temporarily due to falling suction pressure or demand

beyond available capacity.

5. Control valve failure.


The high system pressure alarm will activate at any time when system pressure is high. As soon

as the high system pressure switch senses high pressure at the station discharge, the “high system

pressure” alarm light will turn on. If the system pressure decreases any time before the 10

second delay expires, the alarm light will turn off and the pump will continue to operate

normally. If the system pressure remains high for 10 seconds continuously, the pump will be

stopped and the alarm light will latch on.

To reset the alarm, push the station “reset” button.

Irregular power alarm light (optional)

This light is amber, and is labeled “IRREGULAR POWER”. This alarm detects abnormal

electric power conditions with a power monitor that is located inside the panel. Immediately

after the power monitor senses something wrong on the power lines, the alarm latches on and the

station is shutdown. If power conditions return to normal for 30 seconds, the alarm resets

automatically and the station is allowed to run.

Note: This alarm can be manually reset. You do not have to wait for an automatic reset.

This alarm could be cause3d by any of the following:

1. Incoming line voltage less than 90 percent of normal

2. Power monitor voltage adjustment too high

3. A reversal, shift, imbalance, or loss of line phase(s)

4. Power lines not connected in phase with pump station

5. Blown power monitor fuses

6. Power monitor failure

High temperature alarm light

This light is red, and is labeled “HIGH TEMPERATURE”. This alarm detects high water

temperature at the pump suction. This is a possible indication of a loss of water to the pump. The

temperature switch is located at the pump suction. This alarm could be caused by any of the

following:

7. Loss of suction prime or supply water restriction.

8. Temperature switch failure.

9. Pump failure.

10. Pump discharge isolation valve closed.

11. Pump check valve stuck closed or installed backwards.

The high temperature alarm can activate when high temperature at the pump is indicated. As

soon as the high temperature switch senses high temperature at the pump, the “high

temperature” alarm light will turn on. If the the temperature drops below the switch trip point


any time before the 30 second delay expires, the alarm light will turn off and the pump will

continue to operate normally. If the temperature remains high for 30 seconds continuously, the

pump will be stopped and the alarm light will latch on.

To reset the alarm, push the station “reset” button. This alarm will only reset if the temperature

has dropped below the switch trip point.

Reset Button

This button is red, and is labeled “RESET”. This button is used to perform several functions:

see the following paragraphs.

Push this button to reset an alarm and return to normal automatic operation. If the particular

alarm indicating light does not turn off, the fault condition still exists. Check the alarm and try

to correct the fault to be able to return the station to normal automatic operation.

Pressing this button times out the minimum run timer and allows the pump to stop if it is no

longer required to be running. The pump does not stop immediately since it has a stop delay that

must expire first. The RESET button only releases the pump from its minimum run timer while

it is running. This is a useful feature for testing or monitoring station operation.

Hold this button in for 1 minute to test the PLC input failure alarm. The station will shutdown,

but it will resume normal operation again once the button is released. The only time you need to

hold the RESET button in that long, is when you want to test this feature.

THE PLC (PROGRAMMABLE LOGIC CONTROLLER)

Maintenance

The PLC requires no routine maintenance. The PLC program cannot be lost due to a power

failure, no matter how long power is off. An occasional check of the PLC's status indicators is

sufficient to check for correct operation.

PLC Failure

It is unlikely that a problem will develop with the PLC. If there seems to be a problem, call the

factory for assistance. If a problem does exist, a replacement PLC or program can be shipped to

you.

If the PLC does fail, the pumps can be run “in hand” until it is replaced.

Status Indicators

The operating status of the PLC can be determined by observing the red lights on the front of the

PLC. To do this, the control panel must be open while the power is on. The function of each

light is described below. The electrical schematic shows the physical layout of the PLC.

POWER: Green power lights should be on unless control power is off or the PLC's internal

power supply fuse has blown.

RUN: This light is on if the PLC is operating normally.


PROG-E / CPU-E: If this light is on continuously or flashing on the CPU, an error has been

detected. If the error does not clear by turning power off and back on, call the factory for

assistance.

INPUT & OUTPUT: These numbered lights indicate which signals are coming into the PLC's

inputs (X terminals) and which devices the PLC has turned on with its outputs (Y terminals),

respectively. The electrical schematic shows which device is connected to each I/O point.

PLC Switch Settings

These switches are preset at the factory, so they should not need to be changed. If you want to

check them, turn the power off first.

CPU: The switch on the front right side of the PLC, under the communications door, should be

set to the RUN position. This will allow the PLC to operate normal.

EXTERNAL STATION FEATURES

Main Disconnect Switch

A main disconnect switch is provided with each station. The switch is located outside the pump

house and should be used to turn off all power to the pump station and isolate any main fuses

from incoming power for servicing purposes.

Ventilation Fan

A pump house ventilation fan is provided with each Gator Station. It is used to cool the motor

and control panel from the heat generated by the motor and the environment. It will run anytime

the pump runs, venting the motor heat to the outside of the pump house.

General InformationInstallation

Proper Lifting Procedure

Heavy weight crushing hazard. NEVERwalk or reach under a suspended pump.

DO NOT screw an eye bolt into the motor housing andattempt to lift assembly! The lifting point built into themotor case is not designed to support the combinedweight of the motor and pump.

The crane or hoist must have a capacity in excess of thecombined weight of the motor and pump. Use aminimum of two chains or straps to lift motor/pumpassembly. Each chain or strap must have a capacity inexcess of the combined weight of the motor and pump.

MOTOR / PUMP LIFTING PROCEDURE:Wrap the first chain or strap under the fan end of themotor up tight against the motor feet, and the secondchain or strap under the pump bracket between thepump end and the motor.

Raise motor/pump assembly slowly to ensure that thechains or straps will not slip when put under tension.Balance motor and pump with chains or straps tomaintain proper weight distribution. If not balanced,release tension on the chains or straps and readjust.

Installation

General InformationLOCATION:Locate the pump as near the water source as practical. Makethe pipe run as short and straight as possible, especially if asuction lift is required.Careful attention should be taken to assure that net positivesuction head available (NPSHA) exceeds net positive suctionhead required (NPSHR) by the pump or reduced performanceand severe pump damage may result. If in doubt, check withyour nearest Berkeley professional dealer. Install pump in aclean, dry and drained location readily accessible forinspection and maintenance. Provide ample ventilation.

FOUNDATION: Refer to illustrations at right.

Heavy weights. Use care and properequipment when handling pump for installation. Pump shouldbe set on a concrete foundation which is sufficiently substantialto absorb vibration and which provides a permanent and rigidsupport.

PIPING:System piping should be at least one commercial pipe sizelarger than pump connections and flow velocity should notexceed eight (8) feet per second. In pool installation, flowvelocity should not exceed six (6) feet per second.NOTICE: Take care to align piping with pump case.Misalignment or excessive pipe strain can cause distortion ofpump components resulting in rubbing, breakage and reducedpump life. Support pipe in such a way that no force is exerted on pumpconnections. Check alignment as follows: with the pump shutdown and isolation valves closed, remove pipe flange bolts. Ifthe mating flanges come apart or shift, misalignment is presentand causing pressure on the connections. Adjust pipe supportsuntil flanges mate without any force. This procedure can bedone throughout piping system.

SUCTION PIPING:Refer to Pages 10 and 11 for installation instructions forswimming pool circulating pump applications. Refer to Pages 6through 9 for recommended and not recommended practicesin suction connections in centrifugal installations.

DISCHARGE PIPING:Refer to illustrations on Page 12 and 13 for recommended andnot recommended practices in discharge connections.

ELECTRICAL CONNECTION:

Hazardous voltage. Can shock, burn, orcause death. All wiring should be done by a qualifiedelectrician. Disconnect power to pump before servicing.Check voltage and phase stamped on pump motor nameplatebefore wiring. Be sure they agree with your electric currentsupply. They MUST be the same. If in doubt, check with yourlocal power company.Refer to illustration on for minimum recommendedpumping panel components that help safeguard your pumpduring operation.

CHECK ROTATION:Before pump is put into operation, rotational directionmust be checked to assure proper performance ofpump. Refer to illustration on Page 16.

Hazardous voltage. Can shock, burn, orcause death. Disconnect power to pump beforeservicing.

Do not attempt any wiring changes without firstdisconnecting power to pump.

PRIMING:Pump priming is the displacement of air with water inthe pump and suction piping. Pump MUST BEcompletely filled with water when operating.

Refer to Page 17 for instruction on the followingconditions:

1. Suction lift with priming pump (water sourcebelow pump).

2. Suction lift with foot valve (water source belowpump).

3. Flooded suction (water source above pump, orincoming water pressure is greater thanatmospheric pressure).

SPECIAL CASE - HYDRAULIC BALANCED PUMPS:Hydraulic balanced pumps operate with a very lowpositive pressure across the stuffing box, permitting amuch looser fit of the packing rings around the shaftsleeve to control the loss of water from the pumpthrough the stuffing box. Because of the looser fit ofthe packing rings, air can be more easily drawn into thepump through the stuffing box when priming the pumpwith an air evacuation type primer.

A grease fitting, communicating through the side of thestuffing box to a lantern ring in the packing set, isprovided to grease-seal the stuffing box to prevent airleakage during priming.

If pump cannot be primed due to air leakage throughstuffing box, DO NOT tighten packing. Instead, pumpgrease into lantern ring until back pressure occursforcing grease into the lantern ring, grease-sealing thestuffing box. After priming, when unit is put intooperation, the grease will be flushed out through thepacking by the water flowing outward through thestuffing box. Proceed with normal adjustment of thepacking as described on Page 18. Note that the greaseseal only is used for control of air leaking duringpriming, and that only the packing gland is used tocontrol flow of water through the stuffing box duringnormal operation.

When necessary to replenish the grease supply use anNLGI no. 4 Water Pump Grease.

STARTING:Never run pump dry. Running pump

without water will overheat pump and damage internalparts. Always make sure pump is primed prior to start-up.

NOTICE: Refer to maintenance section if pump haspacking for adjustment prior to start-up.

Prime pump by one of the above procedures. Turn onpower to pump. Slowly open discharge valve untildesired flow rate is achieved. Place the “Hand-Off-Auto”selector switch in the “Auto” position. The pump will bestarted automatically when the pilot device signals themotor starter.

STOPPING:Pump will stop automatically when the pilot device de-energizes the motor starter. Turn the “Hand-Off-Auto”selector switch to “Off” position if you want to stop thepump while it is running.

Direction of Pump Rotation is determined by viewing liquid end of pumpfrom the back or shaft side, and not from looking into the impeller eye or front of volute case. A rotation direction arrow is cast into the pumpbody and shows correct rotation.

Engage start switch momentarily(bump motor) to observe rotationaldirection.

• Electric Motors:

Single Phase: Refer to wiring information on themotor plate to obtain proper rotation.

Three Phase: If pump runs backwards, reverse anytwo leads coming off incoming power (L1, L2, L3)until proper rotation is obtained. Reverse L1 and L2,or L2 and L3, or L1 and L3.

• Pump running backward - Centrifugal pumps will stillpump liquids, however, GPM and head (dischargepressure) will be a fraction of the publishedperformance.

F00634

LUBRICATION:LIQUID END of pump requires no lubrication. Wearrings, packing rings, and models using a mechanicalshaft seal, are lubricated by the liquid being pumped. Donot run dry!

NOTE: Grease fitting in packing area is for priming only.See PRIMING in start-up section for instruction.

MOTOR bearings are lubricated at the factory. Re-lubrication at intervals consistent with the amount of usewill provide maximum bearing life. Refer to motorInstruction Manual for proper motor lubrication andmaintenance instructions.

PERFORMANCE CHECK:Periodically check the output of the pump. If perform-ance is noticeably reduced, refer to TroubleshootingChart.

OBSERVATIONAL MAINTENANCE:When the pump and system operation have beenstabilized, verify that pump unit is operating properly.Observe the following:

VIBRATION: All rotating machines can be expected toproduce some vibration, however, excessive vibrationcan reduce the life of the unit. If the vibration seemsexcessive, discontinue operation, determine cause ofthe excessive vibration, and correct.

NOISE: When the unit is operating under load, listenclosely for unusual sounds that might indicate that theunit is in distress. Determine the cause and correct.

OPERATING TEMPERATURE: During operation, heatis dissipated from the pump and the driver. After ashort period of time, the surface of the pump bracketwill be quite warm (as high as 150°F), which is normal.If the surface temperature of the pump bracket ordriver is excessive, discontinue operation, determinecause of the excessive temperature rise, and correct.Bearings will run hotter for a brief run-in period afterpacking which is normal. However, worn bearings willcause excessive temperatures and need to bereplaced. The pump unit is cooled by the water flowingthrough it, and will normally be at the temperature ofthe water being pumped.

STUFFING BOX: After a short period of operation,verify that the stuffing box area and gland are not hot.

If heating is detected, loosen the gland nuts evenlyuntil water is just running out of stuffing box in aDROPLET form. Water must not be streaming orspraying out. Verify cool operation periodically. Adjustgland nuts EVENLY as necessary for lubrication andcooling of the packing. If packing has been tightened tothe limit of the packing gland travel, additional packingis necessary.

PACKING: Starting new pump.

Before starting pump for the first time, loosen gland nutsand retighten finger tight. Proceed with pump start-upprocedure. Allow packing to leak liberally for a fewmoments. Then tighten gland nuts one complete turneach until leakage is reduced to 40 to 60 drops perminute.

REPACKING:Refer to Page 19.

MECHANICAL SEAL:Adjustment or maintenance is normally not required.The seal is enclosed within the pump and is selfadjusting. Seal is cooled and lubricated by the liquidbeing pumped. Refer to Pages 20 and 21 for removaland replacement. Do not run dry!

PUMP PROTECTION-COLD WEATHER/WET WEATHER INSTALLATIONS:SYSTEM DRAINS: Provide drain valves to emptysystem, including pump case, to prevent freezingdamage.

SHELTER: If possible, provide shelter for unit to protectfrom weather. Allow adequate space around pump unitfor service. When effectively sheltered, a small amountof heat will keep temperature above freezing. Provideadequate ventilation for unit when running. For severeweather problems, where other shelter is not practical, atotally enclosed fan-cooled enclosure can be consideredfor electric motors.

CONDENSATION: When the temperature of metal partsis below dew point and the surrounding air is moist,water will condense on the metal surfaces and cancause corrosion damage. In severe situations, a spaceheater can be considered to warm the unit.
