Viewing Alarms Status
For any active alarm, the parameter will flash if it is displayed. To view a complete list of active alarms, press Menu>Setup>Alarm Setup. Any active
alarm will flash. You may have to scroll through the menu to see all of the alarms.
Relay Setup & Control
M2 Meters provide an option to control an external relay. The M2 can trigger the relay based on high or low temperature levels.
These relay options can be set from the Relay Setup menu. To get there, first navigate to the Setup menu. Then scroll to Relay Setup and press the
Select button.
Relay Normally On/Off
This setting sets the normal operating state of the connected relay. The options are ON or OFF where ON means the relay is on (contacts closed) in
normal operation and OFF means it is normally off (open contacts). Scroll to Relay Normally, press Select (selection will flash), then press the
LEFT ← or RIGHT → arrow buttons to change the setting. Press Enter to save your selection. Press Cancel to cancel a change.
Notification
The Notification setting controls whether or not a notification is displayed when a relay is activated. Notifications will show which relay threshold was
surpassed and for which channel. Scroll to Notification and press Select to change the setting. Press the LEFT ← or RIGHT → arrow buttons to choose
either ON or OFF. ON will display notifications and OFF will not. Use this option if you don't want to be notified that the relay is activating. Press Enter to
save the setting or Cancel to cancel a change.
Silence Relay
Turn this option on if you want the relay to de-activate after the user presses a key on the display. The key press will only de-activate the relay and
will not engage any functions on the meter. For example, this option could be used to silence an external buzzer. Scroll to Silence and press Select to
change the setting. Press the LEFT ← or RIGHT → arrow buttons to choose either ON or OFF. Press Enter to save the setting or Cancel to cancel
any change.
Temp n Delay (Relay)
Set the Alarm hold off time in minutes. The hold off timer operates as a count-up/count-down timer. When the temperature exceeds the alarm value then
the timer will start counting up until it reaches the delay time. When it reaches the delay timer, an alarm will sound. If the alarm condition goes away
before the delay timer has been met, then the timer will count down until the timer is zero again. For example, if the Alarm Delay is set for 5 minutes and
an alarm condition is active for 4 minutes and then inactive for 1 minutes then if the alarm condition is active again, the alarm will sound in 2 minutes (5
minutes - 4 minutes + 1 minute). Note that there is only one delay per channel.
