6.43 Limit relay
For all alarm functions, you can activate one or two output relays as shown below. The following explains how to use an alarm
function to activate an output without activating an alarm. ON and OFF delay timers are described too.
If no alarm is needed, it is possible to do one of the following things:
Set both output A and output B to Limits.
Set both output A and output B to the same terminal. If terminal alarm is not required, the alarm function in the specified relay is
set to M-Logic / Limit relay.
In the example below, the relay closes when the generator voltage is above 103 % for 10 seconds, and no alarm is activated
because both output A and output B are configured to relay 5, which is configured as M-Logic / Limit relay.
The timer configured in the alarm window is an ON delay that determines the time during which the alarm conditions must be met
before activation of any alarms or outputs.
When a relay is selected (relay on terminal 5 in this example), it must be set up as a limit relay as shown below, otherwise an alarm
indication will still appear.
