Loss of Power Indicator
If the OMS loses 24 VDC power, the 4–20 mA analog output signal drops to
0 mA. The display will show a blank screen.
Alarm Reset
If the OMS is supplied with the optional alarm relays, when the monitors alarms
are activated, the built-in alarm relays, panel mounted LEDs, and optional audio
horn will also activate.
When the relay settings are non-latching, the alarm relays, LEDs, and horn will
automatically reset.
If the relay settings are latching, then a manual reset of the alarms is required.
Resetting the alarms can be performed by using the joystick or using the remote
reset function.
•
Joystick—To reset the alarms, enter the password, and then push the
joystick directly in the center to enter the information.
•
Remote Reset—The alarm relay board has a 2-pin connector for
wiring to a remote switch. When connected to a switch, this remote
reset will bypass the joystick and a password will not be needed to
reset the alarms.
The oxygen levels must recover above the alarm thresholds before
the horn can be reset from the remote reset switch or joystick.
