Responding to Alarms
This section describes response to gas, over range, battery, sensor failure, clock failure, and
system failure alarms.
Responding to Gas Alarms
1. Follow your established procedure for an increasing gas condition.
2. Reset the alarm as necessary or allowed.
a. If
LATCH
is set to
ON
(factory setting) in Maintenance Mode, the gas reading must fall
below an alarm setting before you can reset the alarm condition using POWER MODE or
AIR.
If
Password Protection
is turned
On
(factory setting is
Off
) using the 04 Series Setup
Program, you must press POWER MODE and AIR at the same time and then enter a
user-set password to reset an alarm condition. When the password screen appears, adjust
each digit with the AIR button and press and release the POWER MODE button to move
on to the next digit. Once the password is entered, the alarm condition resets.
b. If
LATCH
is set to
OFF
in Maintenance Mode, the alarm condition automatically resets
when gas reading falls below an alarm setpoint.
Responding to Over Range Alarms
1. Follow your established procedure for an extreme gas condition.
2. Reset the alarm using POWER MODE or AIR once the alarm condition clears if
LATCH
is
set to
ON
(factory setting) in Maintenance Mode.
If
Password Protection
is turned
On
(factory setting is
Off
) using the 04 Series Setup
Program, you must press POWER MODE and AIR at the same time and then enter a user-
set password to reset an alarm condition. When the password screen appears, adjust each
digit with the AIR button and press and release the POWER MODE button to move on to
the next digit. Once the password is entered, the alarm condition resets.
3. Calibrate the OX-04 as described on page 43.
4. If the over range condition continues or if you are not able to successfully calibrate the unit,
you may need to replace the sensor.
5. If the over range condition continues after you replace the sensor, contact RKI Instruments,
Inc. for further instructions.
