Operation
7.1.3 Ending special states
Fault / warning indication
Faults and warnings are non-latching. If the fault or warning
condition clears, the message disappears.
To solve warning and fault conditions, display the error code
or warning message (see "Displaying Information", page 15)
and begin troubleshooting (see "Troubleshooting", page 18).
Value under/over measuring range
The display indicates that the gas concentration is beyond the
measuring range of the sensor. The indication disappears as
soon as the gas concentration is within the measuring range.
NOTICE
Sensor malfunction
Gas concentrations beyond the measuring range of the
sensor might cause sensor malfunctions.
►
Check the calibration.
PointGard 2200 CAT with DQ sensor:
An over range has to be acknowledged with [OK] after
verifying that the gas concentration is below 100 %LEL (e.g.
using a portable instrument).
Latching alarms is the default setting of the instrument.
For instruments without relays, the over range can be set to
non-latching. In this case, the over range indication
disappears. The control unit must support this function! For
further information see: "Setting DQ sensor latching",
page 27.
PointGard 2200 CAT Remote with LC sensor:
WARNING
Ambiguous readings at over range measuring values
Latching over range alarms are not supported with LC
sensors.
►
After over range measuring values, verify that the gas
concentration is below 100 %LEL (e.g. using a portable
instrument).
►
If the instrument is connected to a control unit, make sure
that over range latching is active at the control unit.
