Assigning Vo Output Functions

The Vo analog output is a 0-10 VDC signal that varies linearly in relation to a selected function.

To assign a function to the voltage output:

To access the [Vo] option list press

To move the cursor to the desired data function press

To store selection press ENT

Assigning Pgen Output Functions

The Pgen analog output is a buffered TTL-compliant pulse rate signal, similar to the pulse outputs of flowmeters 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

To store selection press ENT

2.10.2 RELAY SETUP

Use this menu to assign a function to channel relays. System 1010 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. Output is a pulse width 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.
