PROBLEM  SOLUTION
Differential pressure is
registering a negative
value.
1. Differential pressure
transducer is installed
backwards.
1. Reverse the process connections to the
differential pressure transducer.
Delivery ends shortly
after it starts..
1. Differential pressure is at
or above the differential
pressure shutdown value.
1. Check the device being monitored. It likely
requires maintenance, such as a lter change.
2. Differential pressure
shutdown setting is set too
low for application.
2. Reprogram the differential pressure shutdown
setting. See page 10 for programming the
differential pressure shutdown setting.
Differential pressure
meets or exceeds the
differential pressure
shutdown setting, but
the delivery does not
end.
1. Faulty output control
shutdown circuit.
1. Check the output control circuit connection. This
output is activated when the differential pressure
shutdown setting is reached or exceeded during a
delivery. Refer to page 9 for details.
2. No output shutdown circuit
is installed.
2. Install an output shutdown circuit following the
instructions on page 9.
Differential pressure
remains at “0” during a
delivery.
1. Differential pressure
transducer has failed.
1. Reverse the process connections to the
differential pressure transducer.
2. Differential pressure
transducer has failed.
2. Replace the differential pressure transducer.
