PERFORMANCE DATA

The following table identifies the specifications forthe Circulating Baths.

INSTALLATION

WARNINGINSTALLATION SHOULD BE COMPLETED BYQUALIFIED PERSONNEL ONLY.

Location - The most uniform operating conditionswill be obtained by placing the bath on a levelsurface in an area remote from drafts, ventilatingoutlets, radiators, and other rapidly changingambient conditions.

Environmental Conditions-This instrument is designed to operate safelyunder the following conditions:

• Indoor Use Only• Temperature: 5° to 40° C• Maximum Relative Humidity: 80% to 31°C,

decreasing linearly to 50% at 40°C• Maximum Altitude 2000 meters• Mains supply voltage fluctuation ±10%, or

per project plan• Installation (Overvoltage) Category II1

• Pollution Degree 22

1 Installation category (overvoltage category) definesthe level of transient overvoltage which the instrumentis designed to withstand safely. It depends on thenature of the electricity supply and its overvoltageprotection means. For example, in CAT II which isthe category used for instruments in installationssupplied from a supply comparable to public mainssuch as hospital and research laboratories and mostindustrial laboratories, the expected transientovervoltage is 2500V for a 230V supply and 1500V fora 120V supply.2 Pollution Degree describes the amount ofconductive pollution present in the operatingenvironment. Pollution Degree 2 assumes thatnormally only non-conductive pollution such as dustoccurs with the exception of occasional conductivitycaused by condensation.

GENERAL INFORMATION

Precision Circulating Baths are widely used inresearch and quality control. Their superbtemperature uniformity and stability makes themespecially desirable for legal or reference tests.

The microprocessor control panel houses allfunctions necessary to operate the bath. The 5push-button switches and single digital displaywindow allow the operator to adjust bathtemperature and temperature calibration via a singleset of controls.

The proportional integral temperature controlcoupled with agitation supplied by a centrifugalpump located in the control housing allows precisetemperature control. Use of the gable cover providedis required to maintain optimal temperaturesensitivity.

A high limit thermostat is provided and can be setto prevent heater runaway in the event oftemperature control failure.

The interior of the bath is constructed of stainlesssteel and is designed for operation with distilledwater or water solutions, such as water /ethyleneglycol with corrosion inhabitants added. The bodyis made from galvanized steel and is painted foradded protection. A drain is located at the far lefthand end of the bath. A stainless steel gable coveris also provided with the bath.

The 240-volt units are identical in appearance tothe 115-volt units.

Electrical Connections -

IMPORTANTFor personal safety, this apparatus mustbe properly grounded.1. The power cord provided on this unit is

equipped with a three-prong (grounding) plugwhich mates with standard three-pronggrounding wall receptacle to minimize thepossibility of electric shock hazard from thisapparatus. If in doubt, the user should havethe wall receptacle and circuit checked by aqualified electrician to make sure thereceptacle can provide adequate current andis properly grounded.

2. Where a standard two-prong wall receptacleis encountered, it is the personal responsibilityand obligation of the user to have it replacedwith a properly grounded three-prong wallreceptacle. Do not, under anycircumstances, cut or remove the third(ground) prong from the power cord. Do notuse a two-prong adapter plug.

Determine the total amount of current being usedby other apparatus connected to the circuit that willbe used for this apparatus. It is critical that theadded current demand (see nameplate) of thisand other equipment used on the same circuitdoes not exceed the rating of the fuse or circuitbreaker.

CAUTIONThe power supply must be the same voltage asspecified on the nameplate.

The power cord is the MAINS disconnect. Be surethat it is easily reached to disconnect the unit fromthe power source.

To avoid build-up of mineral deposits and preventcorrosion, use only distilled water in the bath.Using chlorinated tap water or additives that containchlorine will void the manufacturer’s warranty.Similarly, high purity (deionized) water that doesnot fall into the 50K to 1M ohm range and 7 to 9 pHrange will also void the warranty. Contact TechnicalServices with any questions.

Electrolysis can damage stainless steel. This canoccur if an object is allowed to rest directly on thesurface, trapping moisture that becomes oxygenstarved but is surrounded by water containingoxygen. The resulting electrolytic action will pit orerode the stainless steel.

the power supply board at J102 and thenrepeat steps 3 thru 6. Do not connect theconnector to the CPU board at this time . If theabove voltages are not measured again, thedisplay board has a bad component which isloading down the voltages. If the voltages arestill present, continue on to step 9.

9. Connect the display board ribbon connector tothe CPU board J310 and repeat steps 3 thru 6.If the above voltages are not measured again,the CPU board has a bad component which isloading down the voltages. This board willhave to be replaced.

GENERAL INFORMATION: The POWERSUPPLY PCB ASSEMBLY #3176677 has the triac(solid state AC voltage switch) on it which suppliesthe power to the heater. This triac is "told" tooperate, when need be, by the microprocessor.There is another device known as an opto-couplerwhich serves as the high/low voltage isolatorbetween the triac and the microprocessor.

When the bath starts experiencing temperatureproblem and/or variations, due to known controllermalfunctioning, these two components becomeprime suspects. The reason being they are underhigher operating stress than other components.

If the bath starts experiencing temperature problemssuch as no heat, or "creeping" upward heat, thenfollow the troubleshooting instructions below.These instructions require the use of a voltmeterbeing able to measure DC and AC voltages(preferably digital) and an ohmmeter.

The following is a list of the tools and instrumentsrequired to perform the procedures outlined in theTroubleshooting Procedures table.

Tools Needed:• Phillips or Flat Blade Screwdriver• 7/16" Socket or adjustable wrench• Ohmmeter• DC Voltmeter• AC Voltmeter• 5VDC Power Supply

When changing circuit boards, please useCAUTION when re-installing the flat cableconnectors that come from the display board.Make sure the pins are NOT bent or broken. Boardsthat are otherwise fine will not operate correctly ifthese pins have been abused because they will notreceive the necessary signals from other boards.

Before attempting any troubleshooting for aparticular problem, it is good practice to verifypower supply voltages of the POWER SUPPLYboard #3176677. Read these steps beforeperforming them to get acquainted with theprocedure. Refer to Figure 1 on page 13.

1. Be sure that the main power source is OFF ordisconnected.

2. Connect J101 and J105 to the POWERSUPPLY BOARD. DO NOT connect J102that comes from the CPU and the DISPLAYat this time.

3. Connect the negative lead of the voltmeter toTP2 - COM. Select a VDC of 20. Connect thepositive lead to TP1 - UNREG.

4. Turn ON the main power.

5. The voltmeter should be reading approximately14 volts DC ±2.

6. Connect the positive lead to TP3 ±5V. Thevoltmeter should be reading +5 volts DC ±0.5.

7. Turn OFF main power.8. Connect the display board ribbon connector to

c. Measure the output of the temperaturesensor at J302 pins 2 & 3. Pin 3 being thereference or ground. The outputrelationship of voltage to °C is listed in thetable below. Compare the measuredvoltage to the temperatures listed todetermine if the probe is working.

5. The bath is not heating when it should berequesting heat. Voltage measurements aremade on the POWER SUPPLY BOARD#3176677. Refer to Figure 1 on page 13.

a. Select a setpoint temperature at least10°above what the actual temperature is.The bath should be requesting heat asindicated by the heater "ON" indicatorlamp on the front panel. It should be oncontinuously, not flashing.

b. Measure the voltage at U1-PIN 2 withrespect to TP2-COM. It should be nogreater than 4 VDC.

c. Measure the DC voltage across R4. Sincethe bath is requesting heat, there shouldbe current flowing through this resistormaking the voltage drop equal to 3VDC,±0.5.

d. If the last two steps are not as stated, thenmost likely the CPU board is bad and it willhave to be replaced.

e. Switch the voltmeter to an AC volts scalecapable of reading 120 volts.

f. Measure the voltage between U1-PIN 4and U1-PIN 6. It should be less than 1VAC.

g. If it is not, then most likely the opto-couplerU1 is bad and the POWER SUPPLY boardwill have to be replaced. If it is, continueon.

WARNINGTHE FOLLOWING TROUBLESHOOTINGINSTRUCTIONS REQUIRE THAT POWER BEON. ONLY QUALIFIED SERVICE PERSONNELSHOULD PERFORM THESE PROCEDURES.

Open the control cover and familiarize yourselfwith the POWER SUPPLY assembly #3176677.Locate the triac (Q2), the opto-isolater (U1), theresistor (R4), and the test point #2 (TP2-COM).The first measurements will be DC voltagemeasurements. A DC scale of at least 10 voltsshould be selected.

1. The most common problem cause of thisproblem is the failure of the driver integratedcircuit on the DISPLAY/KEYBOARD board(#3176679). Replace it.

*** Problem F: Pump Does Not Circulate *** Water

1. Verify that the water level is above both thepump inlet and outlet.

2. If the pump is not running, verify that power isapplied to the bath. If power is present, checkwiring of pump to power switch. If wiring iscorrect, replace the pump.

3. If pump is running but water is not circulating,open the control panel and gently squeeze thelong piece of rubber tubing a few times to helpremove any air trapped within the pumpingsystem.

4. If water is still not circulating, check for foreignmatter in the pump inlet fitting.
