Clearing Alarms
When an alarm occurs, the buzzer will sound, the red ALARM LED will light, and the screen will display which alarm was triggered, the Alarm set point
and the current value. Pressing any button silences the buzzer and another button press returns to the previous display.
Until the cause of the alarm is resolved, the ALARM LED will remain on and the channel that triggered the alarm will blink.
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 deactivate after the user presses a key on the display. The key press will only deactivate 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.
