« Cause
The calibration interval for
DrägerSensor XXS EC2 has
elapsed
Alarm setpoint A2 setting is
greater than 60 %LEL
DrägerSensor XXS EC3 in
the warm-up phase
DrägerSensor XXS EC3 in
the warm-up phase
EC3 concentration has drifted
into the negative range
The temperature is too high
The temperature is too low
The calibration interval for
DrägerSensor XXS EC3 has
elapsed
Alarm setpoint A2 setting is
greater than 60 %LEL
The calibration interval for the
compensation electrode has
elapsed
Calibration required because
of overgassing.
DrägerSensor XXS EC 4 in
the warm-up phase
DrägerSensor XXS EC 4 in
the warm-up phase
EC 4 concentration has drifted
into the negative range
The temperature is too high
The temperature is too low
The calibration interval for
DrägerSensor XXS EC 4 has
elapsed
Alarm setpoint A2 setting is
greater than 60 %LEL
Remedy
