4.4 Loss of Power Indicator
In the event the Dual O2/CO2 monitor loses 24VDC power, the 4-20 mA analog output
signal drops to 0mA. The LCD display will also display a blank screen.
4.5 Alarm Reset
The Dual O2/CO2 monitor is supplied with individual alarm relays for each gas.
Whenever the monitor’s alarms are activated, the built-in alarm relays, panel mounted
LED’s and audio horn will also activate. When the relay settings are non-latching, the
alarm relays, LED’s 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
through use of the joystick or through the use of the remote reset function.
Joystick
– You must enter the password to enter the reset function. After the password
is entered and accepted, push the joystick in (enter) to reset the alarms.
Remote Reset
– See section1.2.7. The alarm relay board has a two-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.
NOTE : The oxygen levels must recover above the alarm thresholds before the
horn can be reset from the remote reset switch or joystick.
