1. Press the STOP/START key until the pump starts running and then press
it one more time so the pump is in the WAIT mode and sitting idle.
2. Press and hold the EXT key until EXT is displayed in the User
Program Menu.
3. Press the DOWN Arrow key 3 times until FL.CHK is displayed.
4. Press the DISP key once and OFF will be displayed showing the
program for the PosiFlow sensor is off.
5. Using the UP and Down Arrow keys, select one of the three programs
that best suit the your output needs (A, b, or C.Mode).**
6. Press the DISP again and use the UP and DOWN keys to select the
number of user-defined strokes you would like to allow the PosiFlow to
miss before sending an alarm.
7. Press the DISP key again and it will go back to “FL.CHK.
8. Press the START/STOP key and it will go back to the WAIT mode.
9. Now, every time the pump is in operation, whether by MAN mode or via
an EXT signal, once the pump has stroked the number of times preset and
there has been no input contact from the PosiFlow, the pump will stop
operation, the OUT 1 Relay will close and the display will flash
FLOW”. OUT 2 can also be changed in the User Program Menu to also
close when the FLOW” alarm is active. This is independent of OUT 1.
Once the FLOW” alarm is indicated and the pump stopped, manual
intervention (pressing the STOP/START key) is then required to reset the
Alarm/Error code.
NOTE: Do NOT turn on the PosiFlow Sensor program unless a PosiFlow is
attached and plugged into the pump. The pump will always error out and stop
without the sensor.
**DEFINITION OF POSIFLOW MODES:
A.MODE: The pump will stop, OUT 1 (and OUT 2) will close, and
FLOW” will be displayed once the pump has stroked the
user-defined number of pulses without getting a signal from
the PosiFlow sensor.
B.MODE: Once the user defined number of pulses without a signal from
the sensor has been reached, OUT 1 (and OUT 2) will close,
but the pump will continue to run for another 360 strokes. If
there is still no signal from the PosiFlow, then the pump will
stop and FLOW” will be displayed.
C.MODE: Once the user defined number of pulses without a signal from
the sensor has been reached, the pump will continue to
operate for another 360 strokes. If there is no signal from the
PosiFlow at that point, OUT 1 (and OUT 2) will close, the
pump will stop and FLOW” will be displayed.
