Display mode and error signals
The current measurement value is displayed in the selected unit in the normal mode. As for the
selection of the unit, see section 8.3.
If a fault occurs which can be detected by the GUT, one of the following messages is displayed until
the fault is cleared:
•
Err INT
•
Err MEM
•
Err SB
•
Err SC
•
Err CJC
•
Err SB RED if the redundant thermocouple function has been selected (see section 8.2.3) and a
•
Err RED
•
Err DV RED (for "deviation from redundant TC"), if the redundant thermocouple function has been
Be aware that the error signals Err SB, Err SC, Err SB RED and Err RED refer to the sensor function
and not to the sensor lines.
In case of a fault, the relays normally switch to the idle state. Exceptions are described in section 8.2.4
and section 8.5.1 (Maintain in case of error).
The behaviour of the current output in case of a fault is described in section 8.2.4 and section 8.6.2.
Subject to reasonable modifications due to technical advances.

in case of a sensor breakage (only for the sensor types RTD and TC);
if the redundant thermocouple function has been selected (see section 8.2.3), a
sensor breakage may also trigger the message Err DV RED (see below)
in case of a sensor short-circuit (only for RTD sensor type)
if the internal cold junction compensation has been selected (see section 8.2.3) and
a breakage or short circuit has occurred within the K-CJC terminal
sensor breakage has occurred in the second thermocouple
if the redundant thermocouple function has been selected (see section 8.2.3) and a
sensor breakage has occurred for both thermocouples
selected, two thermocouples are connected and the tolerated deviation is exceeded
between the two couples is exceeded (see section 8.2.3 and section 8.2.4)
