Operation
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 B and Y buttons (see Fig. 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 acti-
vated). When all cycles have been performed, the
pump will stop and the CYCLES display will automati-
cally 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 pumping cycle. The CYCLES display will
blink to indicate that the RUN mode was interrupted.
Once in this mode, there are two possible actions:
pressing the RUN button will resume the pump cycling
where it was interrupted or pressing the RESET button
again will reset the CYCLES to the full count for the
current PRESET.
Remote Operation
The B and Y buttons select the desired PRESET
number of pump cycles. Pump cycles for each PRE-
SET 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 the diaphragms alternately acti-
vated). When all cycles have been performed, the
pump will stop and the CYCLES display will automati-
cally be reset to the full cycle count for the current
RESET.
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: closing the REMOTE
RUN contact again will resume the pump cycling
where it was interrupted or 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.
