“DIGITAL INPUT” and “INPUT TRIGGER” submenus

Digital Input 1

Output R1

Any O/P Contacts or Any Opto Inputs or
Internal Digital Signals

The relay 1 output digital channel is assigned to this channel. The digital channel will
trigger the disturbance recorder when the corresponding assigned fault will occur. In this
case, the digital recorder will trigger when the output R1will change.

Following lines indicate default signals for the 32 channels.

Input 1 Trigger

No Trigger

No Trigger, Trigger L/H, Trigger H/L

This digital channel will not trigger the Disturbance recorder. When “Trigger L/H” is
selected, the channel will trigger the disturbance recorder when changing from ‘0’ (low
Level) to ‘1’ (High level). If “Trigger H/L” is selected, it will trigger when changing from ‘1’
(high level) to ‘0’ (low level).

Following lines give default settings up to channel 32.
