Align Refill Switch Mode: The signal that initiates the refill phase
can be displayed during power-up by pressing and holding the PRIME
and the UP-ARROW buttons when the power is switched on. Release
the buttons when the display displays "rFL". When the slotted disk
allows the light beam to pass from the emitter to the detector on the
slotted optical switch a pulse will be generated which signals the
beginning of refill. When this pulse occurs the three horizontal
segments displayed at the top of the display will turn off and the three
horizontal segments at the bottom of the display will turn on. To exit
this mode, press the RUN/STOP button.
Serial Port Loopback Test Mode: If an external device will not
communicate to the pump via the serial port, the serial port loopback
test can be used to verify that the serial port is functioning properly.
During power-up press and hold the UP-ARROW and the DOWN-
ARROW buttons when the power is switched on and then release the
buttons. The display must display "C00" for the first half of the test to
pass. Plug in the serial port loop back plug (A modular plug with pins
2 & 5 jumpered together and pins 3 & 4 jumpered together.). The
display must read "C11" for the second half of the test to pass. To exit
this mode, press the RUN/STOP button.
