LPT-M - Operation Manual
6.9.2 Setting Relay ON / OFF Delay
The LPT-M comes with a confi gurable ON and OFF delay for its relays. In the event of a gas build up
in excess of the level set for the specifi ed alarm level, the relay will be triggered. If an ON DELAY has
been set, the relay will remain unchanged until the time delay has expired, at which time the relay
will “trip”. If the gas level falls below the set alarm level before the delay has fi nished, the alarm will
be cancelled and the delay will be reset for the next alarm. If an OFF DELAY has been set, the relay
will stay tripped for the duration of the RELAY OFF DELAY.
NOTE:
Each channel will trip the relay according to that channel’s alarm setpoints and relay alarm
level assignment setting.
To set the Relay ON DELAY:
In the Hardware Confi guration Menu (passcode 1001), press either ARROW to scroll through the
menu and select Program Relay. Press ENTER to select. Scroll through the menu and choose Relay
Delay On.
Press ENTER to access the screen and use the ARROW keys to increase or decrease the number. Press
ENTER to move to the next digit and again to save and Exit the screen.
To set the Relay OFF DELAY:
In the Hardware Confi guration Menu (passcode 1001), press either ARROW to scroll through the
menu and select Program Relay. Press ENTER to select. Scroll through the menu and choose Relay
Delay OFF.
