9.1.3 How to Select the Output Relay to be Energizing/De-energizing on Alarm
The alarm output relays can be selected to be energizing or de-energizing on alarm.
Using de-energizing, alarm output relay is activated either when an alarm occurs, or
when power off occurs (common for all relays). This enables simple monitoring of
power supply.
The initial value is ‘ENERG’.
SETTING PROCEDURE:
Enter the SET UP Mode by turning ‘ON’ the power while pressing and holding the
ENT-key until the SET UP display appears.
Use the UP/DOWN-keys to select the display ‘SETUP=ALARM’. Press the ENT-key.
Press the ENT-key until the display ‘ALARM=ENERG’ appears. Select energize
(ENERG) or de-energize (DE_EN). After selection, press the ENT-key.
The energize/de-energize setting has been completed, but has not been stored yet.
Before you can adjust other settings in the SET UP Mode, you have to finish the alarm
settings until the ‘*ALARM SET*’ display appears.
Before leaving the SET UP Mode, you have to store your new settings. Proceed with the
alarm settings until the display ‘*ALARM SET*’ appears. Press the ESC-key to return
to the ‘SETUP=ALARM’ display and then select the ‘SETUP=END’ display.
Press the ENT-key. Select ‘END=STORE’ to keep your new settings or
‘END=ABORT’ and press the ENT-key. After a few seconds, the Operation Mode will
appear.
