Drive Structure

Control Card Controls the motor and end of stroke sensors.

Step Motor Moves the transmission system. The step motor used, with integrated drive, allows to reduce the dimension and complexity of the electronic card and improves the dynamic response of the valve.

Timing Belt The timing belt transfers the rotating movement to the screw. The timing belt is maintenance free.

Screw The screw converts the rotating movement of the step motor to a linear movement.

Springs The springs placed in the junction between the valve and the stem allow to apply a force to ensure the perfect closing of the valve. Is important to verify the compression of the springs to adjust the closing of the valve without overcome the maximum torque calculated for the motor and transmission (see the note in page n.3).

Electrical connections Remove the cover of the valve to access to the control board. In the bottom of the board there are two connectors with two different cables.

Externals cables connectors

J1 Supply motor and control board Cable 4 Wires + Ground (0.5 mm2)

J3 Analog input signals and digital input/output signals Cable 4 Wires + Shield (0.5 mm2)

Other connectors

J4 Zero sensor in reverse mode J5 Zero sensor in direct mode J2 Cable supply and signals to the motor. The electrical connection of this cable is Pin To Pin (1-1, 2-2 etc.)

Calibration procedure The calibration procedure is necessary to give the Maximum Stroke and Zero to the positioner. The Zero point corresponds to a reference signal of 4 mA, the Maximum Stroke signal corresponds to a reference signal of 20 mA.

Work direction Dip Switch 4

OFF Direct (the zero position is in the lower position of the valve) CO2 valve ON Reverse (the zero position is in the upper position of the valve) Water and Syrup valves

High and Low speed Dip Switch 5

ON Low speed (not used) OFF High speed (all the valves)

Calibration of close position 1. Set the switch 4 (Direct/Reverse) in the right position (see above). 2. Set the switches 1,6,7,8 in OFF position. 3. Switch on the power supply to the valve. 4. Delete any previous calibration of the valve restoring the factory

conditions: to do that set the switch 2 in ON position for 1 Sec. 5. Set ON the switch 1 in the control board. 6. Put the valve in the right zero position, (corresponding to an input

signal of 4 mA) with the pushbuttons UP and DOWN, paying attention to the spring compression1 (see picture).

7. If the spring is too compressed is possible that the motor looses the step; in this case bring again the Switch 1 in OFF position and repeat the procedure from point n. 4.

8. Store in the eeprom memory the zero position setting ON and then OFF the switch 2 in the control board (the red dot of the display will switch on to confirm the storage of the calibration).

Calibration of maximum opening position. 9. Put the valve in the maximum opening position, 40 mm from the full close position, (corresponding to an input

signal of 20 mA) with the pushbuttons UP and DOWN. 10. If the physical maximum opening position is overcomed is possible that the motor looses the step; in this case bring

again the Switch 1 in OFF position and repeat the procedure from point n. 4. 11. Store in the EEprom memory the zero position setting ON and then OFF the switch 3 in the control board. 12. Set OFF the switch 1 to leave the learning mode and set ON the switch 6 to enter in automatic mode.

Check of calibration. At the end of calibration procedure we recommend to check the calibration of the valve and the compression1 of the spring opening and closing the valve from the PC maintenance screen; if its no good repeat the calibration.

Working Modes

Automatic Mode Switch 6 ON Switch 7 OFF Switch 8 OFF

Automatic Mode active: the valve follows the analog input reference 4..20 mA

Manual Mode Switch 6 OFF Switch 7 ON Switch 8 OFF

Manual Mode active: is possible to move manually the valve using the pushbuttons UP and DOWN

Test Mode Switch 6 OFF

1 The valve is close correctly when, in the zero position, the spring is compressed about 0.5mm. Is very important to pay attention to

the spring compression during the zero position calibration, because overcoming the maximum torque is possible to damage the transmission system and the belt of the valve; in the other hand a spring compression too low may not ensure the correct closure of the valve.

Switch 7 OFF Switch 8 ON

Test Mode active: the valve does full strokes between 0% and 100% position

RESET Mode Switch 1 OFF Switch 2 ON ( 1 Sec ) Switch 6 OFF Switch 7 OFF Switch 8 OFF

RESET Mode: deletes any calibration of the valve restoring the factory conditions.
