and time delay, the pickup setpoint may be used to dictate whether the feature
picks up when the measured value is over or under the level.
For example, if a pressure transducer is to be used for a pump application, program
the following setpoints:
ANALOG INPUT 1(4) NAME:
ANALOG INPUT 1(4) UNITS:
ANALOG INPUT 1(4) MINIMUM:
ANALOG INPUT 1(4) MAXIMUM:
If there is no pressure until the pump is up and running for 5 minutes and pressure
builds up, program the
ANALOG INPUT 1 BLOCK FROM START
The alarm may be fed back to a PLC for when pressure is under 300 PSI. Program a
reasonable delay (e.g
ANALOG INPUT ALARM 1 DELAY
as "Under".

If a vibration transducer is to be used for a pump application, program the following
setpoints:
ANALOG INPUT 1(4) NAME:
ANALOG INPUT 1(4) UNITS:
ANALOG INPUT 1(4) MINIMUM:
ANALOG INPUT 1(4) MAXIMUM:
Program
BLOCK ANALOG INPUT 1(4) FROM START
reasonable level slightly higher than the normal vibration level. Program a delay of
"3 s" and a pickup value of "Over".
