Assigning Io Output Functions (see paragraph 4.8)
The Io analog output is a loop-powered (or externally powered), isolated 4-20 mA DC signal
that varies linearly in relation to a selected data function.
To assign a function for the current output:
From [Analog Out Setup], press twice to access the [Io] option list.
Move the cursor to the desired data function by pressing
To store selection press
NOTE: The meter’s 4-20 mA output will drop to approximately 2 mA in the event of a
sensing fault alarm.
Assigning Pgen Output Functions (see paragraph 4.8)
The Pgen analog output is an opto-coupled pulse rate signal. It varies linearly from 0-5000 Hz
in relation to a selected data function.
To assign a function for the Pgen output:
To access the [Pgen] option list press
Move the cursor to the desired data function by pressing
To store selection press
2.8.2 RELAY SETUP
Use this menu to assign a function to channel relays. System 1010 supports 2 types of re-
lay outputs, Alarm Relay and Pulse Relay. Alarm Relay outputs operate in “fail-safe” mode.
The relay(s) are energized 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 approximately 200 ms; maximum activation rate is 2.5
pulses per sec. If totalizer pulses exceed this rate, excess pulses are stored in an overflow
register. This allows the relay to “catch up” when flow decreases enough.
