Priming the Pump
A priming feature allows for the temporary operation of the pump for priming purposes. The pump cycle rate
during priming is controlled by the 8 position DIP switch (SW1).
Pressing the PRIME button on the front panel will start the pump cycling while the button is held. Once primed,
release the button to stop pump operation.
Front Panel Operation
The ü and ù buttons (see figure 5) select the desired PRESET
pump cycle. The pump cycle count for each PRESET is
displayed in the CYCLES display.
Pressing the RUN button on the front panel starts the pump
cycling for the number of cycles indicated by the CYCLES
display. The CYCLES display will count down from its current
count every time the pump performs a complete cycle (both
diaphragms alternately activated). When all cycles have been
performed, the pump will stop and the CYCLES display will
automatically be reset to the full cycle count for the current
PRESET. The unit is then ready for another dispense cycle.
Pressing the RESET button during a RUN operation stops the
pump cycling. The CYCLES display will blink to indicate that the
RUN mode was interrupted. Once in this mode there are two
possible actions: 1.) pressing the RUN button will resume the
pump cycling where it was interrupted. 2.) pressing the RESET
button again will reset the CYCLES to the full count for the
current PRESET.
Remote Operation
The ü and ù buttons select the desired PRESET number of
pump cycles. Pump cycles for each PRESET are displayed in
the CYCLES display.
Closing the REMOTE RUN contact starts the pump cycling for the number of cycles indicated by the CYCLES
display. The CYCLES display will count down from its current count every time the pump performs a complete
cycle (both diaphragms alternately activated). When all cycles have been performed the pump will stop and the
CYCLES display will automatically be reset to the full cycle count for the current PRESET.
Opening the REMOTE RUN contact stops the pump cycling. The CYCLES display will blink to indicate that the
RUN mode was interrupted. Once in this mode there are two possible actions: 1.) closing the REMOTE RUN
contact again will resume the pump cycling where it was interrupted., 2.) pressing the RESET button on the front
panel will reset the CYCLES to the full count for the current PRESET.
When all cycles have been performed, the pump will stop and the CYCLES display will show 000 until the
REMOTE RUN contact is opened. The CYCLES display will then automatically be reset to the full cycle count for
the current PRESET.
