Satellite XT R Version
This section will help to determine the source of a fault or
warning condition and will provide a corrective action.
7.1
Warning and Fault Messages
There are two general indications, warnings and faults, which require different attention.
If a fault or warning message does not appear in this section or if further assistance is
required, contact your MST Service Department.
7.1.1 Warnings
A warning condition indicates that the instrument requires some attention, but the
instrument is still able to monitor and operate as programmed.
The following will occur when the instrument detects a warning condition:
- the green status LED is flashing
- depending on the configuration, the fault relay will be activated
Press the <set> key to acknowledge and reset a Warning Condition.
Low Zero !
This message indicates that the zero point of the sensor is out
of the optimum range.
To correct this problem, check the zero adjustment and
recalibrate, if necessary.
Check Sensor !
This message indicates that the sensor sensitivity does not
comply with the specifications.
The sensor must soon be replaced.
Whilst most sensors will work for another 2-6 weeks, there
are circumstances that may cause an earlier failure of the
sensor cell. Honeywell therefore suggests that customers with
more critical needs carry out the replacement of the sensor
cell within 3 days (72 hours) of receiving the “check sensor”
message.
To receive this message, the function Auto Selftest must be
enabled; refer to Section 6, Configuration.
! This function is not available for instruments with
oxygen sensor.
