Assigning Pgen Output Functions
The Pgen analog output is a buffered TTL-compliant pulse rate signal, similar to the pulse outputs of flow-
meters such as turbines. It varies linearly from 0-5000 Hz in relation to a selected data function.
To assign a function to the Pgen output:
To access the [Pgen] option list press
To move the cursor to the desired data function press

2.10.2 RELAY SETUP
Use this menu to assign a function to channel relays. FUE1010EN supports 2 types of relay outputs,
Alarm Relay and Pulse Relay. Alarm Relay outputs operate in “fail-safe” mode. The relay(s) are ener-
gized under normal conditions - an alarm condition causes the relay(s) to de-energize until alarm clears.
The Pulse Relay output supports totalizer and batch relay functions. The output pulse width is approxi-
mately 200 ms; maximum activation rate is 2.5 pulses per second. If totalizer pulses exceed this rate,
excess pulses are stored in overflow register. This allows the relay to “catch up” when flow decreases
enough.
NOTE: Using <F1> Totalizer clear command also clears all channel totalizers plus the overflow
register described in the last paragraph.
Assigning Relay 1 and 2 Functions
FUE1010EN, depending on the model, provides at least two alarm relays. Please refer to the Hardware
Installation Drawing for wiring details. Relays respond to any of the alarm conditions/data functions in-
cluded on the Relay Option List.
