SSI America BINARY SOLVENT DELIVERY MODULE 90-2581 REV B - Manual (Page 19)

4-3
Motor Stall Detector press the DOWN-ARROW button and the
display will display "OFF". To exit this mode and store the current
setting in non-volatile memory, press the RUN/STOP button.
The Motor Stall Detector uses a timer to determine if the camshaft has
stopped turning or if the refill switch is defective. The timer begins
timing after the pump accelerates or decelerates to its set point flow rate.
If the Motor Stall Detector has been enabled, and the camshaft stops
turning or the refill switch stops operating, the fault will be detected
between the time it takes to complete 1 to 2 pump cycles. One
revolution of the camshaft produces a delivery phase and a refill phase.
The fault is canceled by using one of the following methods: (1) by
pressing the RUN/STOP button on the front panel, (2) by sending a
stop command "ST" via the serial communications port on the back
panel, or (3) by connecting the PUMP-STOP input to COM on the
back panel, or removing the connection between the PUMP-RUN
input and COM if the PUMP-STOP input is permanently jumpered to
COM on the back panel. Note: the PUMP-RUN, PUMP-STOP, and
COM are an option and do not exist on the standard pump.
