(two-wire cable between pin 9 and pin 30) allows you
to monitor VitaPump alarm conditions. (5.0VDC output control signal, requires use of a solid state
relay that will trip at 3 volts; is low (0 volts) when off, and high (5 volts) when tripped.
An additional TTL
output
will provide you with a similar signal to provide a Status Signal that is On
(5 volts) when the VitaPump’s motor runs, and Off (0 volts) when it isn’t. (two-wire cable between
pins 12 & 31) (5.0VDC output control signal, requires use of a solid-state relay that will trip at 3
volts)
A TTL input (two-wire cable between pin 19 and pin 37) allows remote “RUN” / “STOP” by means of
dry contact closure. This last feature is set to LEVEL (contact closure) by default for input from your
control system. It can be set to PULSE to allow use of the RUN button in Metering Mode.
All three cables are usually assembled as a set into one head shell and tested at Parker prior to
shipment.
