NOTE: These are the closest values of current limiting 5%, ¼ watt resistors for the applied voltages. Volt-

age control sources must have series resistors as shown in Table above, to limit control signal currents to

the input opto-isolators, Pins 3, 6, 9, on P1.

2.2 RUN / PURGE MODE

A current of 6 to 20mA must be supplied continuously throughout the signal current input at P1, Pin 9

(VIOLET) to keep the dispenser in a continuous run mode. THE ABSENCE

OF THIS SIGNAL WILL

HOLD THE PUMP IN A DISPENSE MODE ONLY. Run / Purge Actuation is handled by Pin 9 (VIOLET)

(+ side sinking) and 7 (WHITE) (return) on the input connector P1 (see Figure 1, Page 1), by providing a

current of 6 to 20mA through a switch closure, PLC, Relay, Mechanical Timer/Counter or transistor output

2.3 Timed/Count Dispense/Continuous Run Mode

To activate this mode for a timed dispense system, the closing of dispense switch 9 is done externally

using a control signal current input at P1 Pin 9 (VIOLET) for one dispense per signal. The pump will

begin running when this connection is closed

, and rotation will cease when the control current is turned

off from Pin 9 of P1. The current must be provided through a resistor (the typical values are shown

on Table 2 below) from a counter or timer that can control a SPST relay or switch closure. External

counters and PLCs can use the VERIFY SIGNAL OUTPUT (P1 Pin 3 (BLUE), verify return common Pin 5

(ORANGE)) to sense and count each revolution pulse. If no PLC is used, a standard industrial counter

such as OMRON H7CR can be set to count up to 9999999 revolutions, and then stop.
