4.0 OPERATION
WARNING:
Tube failure may result in fluid being sprayed from pump. Use appropriate measures to
protect operator and equipment. Tubing should be inspected periodically for tears, cracks, cuts, or
abrasions.
WARNING!
Use only factory approved tubing from the designated tubing class. Incorrect tubing can
adversely affect performance or damage the pump.
4.1 Controls
All pumps are equipped with a rocker switch mounted on the front of the pump. Always confirm the
switch is in the designated Off position before plugging the pump into any power receptacle.
2-Way Rocker
- For units equipped with a two-way rocker, the up position is On, and the down
position is Off.
3-Way Rocker
- For units equipped with a 3-way rocker, up is On, center is Off, and the down
position is either External mode, or Run mode, depending on the pump model.
Potentiometer
–
Variable speed models are equipped with a single turn potentiometer on the front
of the pump which regulates the speed. Cycle timed models are equipped with a 10-turn
potentiometer allowing for precision control of run time setting.
4.2 Adjusting Flow Output
Fixed Speed Models
– There is no flow output adjustment.
Variable Speed Models
– Flow output is controlled by motor speed utilizing the potentiometer.
Rates are adjustable from approximately 5% to 100%. If equipped with a 4-20mA control option,
pump speed will vary as the dedicated input signal changes amplitude.
Please refer to Remote
Operation below for more details on 4-20mA operation.
Cycle Timer Mode
ls
– Cycle time is defined as the sum of the on time plus off time. On time is set
by the position of the potentiometer and can be incremented up to the model’s maximum total cycle
time. When the 3-way rocker switch is in the down position (Run Mode), the pump will dispense for
the selected time, remain off for the balance of the total cycle time, and then repeat the on cycle
indefinitely until the pump is powered off or switched out of the Run Mode.
4.3 Remote Operation
Remote Start/Stop
–
For pump models equipped with remote start/stop, this feature operates by
receiving a dry contact signal and is intended to be connected to a dry contact switch. The input has
no polarity. No voltage is permitted on the input signal. The pump will activate and run while the
switch is closed and deactivate and stop when the switch opens.
To activate this feature, install the pair of wires from the dry contact switch
closure device into the terminal block (Figure 1). Set the 3-way rocker in the
down position to place the pump in External mode. The pump will now operate
only when receiving a closed contact signal. To return to local control, move the
rocker switch to the up, Internal mode, position.
