Fault – Cause – Remedy
# 130 The function » Sensor lock « is active. A
sensor with a different Part No. has been
inserted.
Deactivate the function » Sensor lock «, page 76 or use a
sensor with the same Part No. as the one which
was removed.
# 134 Bad contact between the sensor and
the sensor card.
Check the sensor contacts. Remove and reinstall the sensor
several times. If the problem persists, install a new sensor,
page 44.
# 136 Sensor hardware fault. Remove the sensor and install it again. If the problem per-
sists, install a new sensor, page 44.
Warning number Cause Remedy
# 1 Data error in the unit. Certain functions
such as the Datalogger or the dongle func-
tions may not be available.
Initialise the unit with the menu items » Settings «,
» Instrument «, » Init. device «, page 67.
If this error occurs again: have the transmitter checked by
DrägerService.
# 51 Datalogger is in stack mode and is 100 %
full. No more data can be recorded.
Read out the data. Then clear and restart the Datalogger
# 52 Datalogger is in stack mode and is 90 %
full.
Read out the data as soon as possible. Then clear and
restart the Datalogger.
# 53 No valid date and/or time is set. Set the date and time, page 65.
# 58 Software dongle was removed without log-
ging off.
Deactivate the function in the menu » Settings «,
» Instrument «, » SW dongle «, » XXX dongle «, page 68.
Hardware fault in the software dongle. Change the software dongle, page 29.
# 59 Pump worn. Change the pump module, page 33.
# 64 Pump gasflow falls below the configured
warning threshold. Reliable measurements
are no longer possible.
Check the hoses for blockages,
If necessary adjust pump flow.
# 106 Increased zero-point offset. Zero-point calibration, page 56.
# 111 Sensor is not working in the specified tem-
perature range.
Operate sensor in the specified temperature range (see
Instructions for Use of the sensor).
# 112 Sensor near end of life. Replace the sensor, page 44.
# 114 Calibration interval expired. Recalibrate the unit, page 42.
# 115 Sensor was operate for too long with a
high concentration.
Reduce overgassing.
# 119 Sensor is not yet fully warmed up. An
increased measuring error must be
expected.
Wait until the sensor has fully warmed up.
# 120 The sensor has been exposed to an exces-
sively high gas concentration for a long
period.
Reduce the exposure to high gas concentrations. If this
does not help, replace the sensor, page 44.
# 131 Bad sensor, no longer operating. Replace the sensor, page 44.
# 132 Electrolyte liquid evaporates. Measure-
ments will soon no longer possible.
Refill electrolyte. See sensor data sheet.
# 135 Information such as the Part No. and the
Serial No. is not available.
Disconnect the unit from the mains and restart it.
If this error occurs again: have the transmitter checked by
DrägerService.
