Error codes
Problems during measurement or faulty adjust-
ments during the programming are indicated on the
display with a fault signal.
Fault signals are made in the measured value
(mode) with channel specific indication via the
respective display.
The following fixed coordination is valid:
- display 1 indicates fault signals of channel 1
- display 2 indicates fault signals of channel 2,
also if the differential result has been coordinated to
the respective display (mode 40).
Acc. to the table below, fault signals can cause the
fail safe relay to de-energize and the failure LEDs
light (channel 1 = LED 1, channel 2 = LED 2).
The current outputs as well as the switching relays
react channel specific acc. to the table below or
their parameter adjustment in mode 93.
After removing the failure (e.g. repair of a line
break) the fault signal extinguishes automatically.
Example of a fault signal:
1 E 3 . 0 4 Fault in channel 1:
line break / temperature
sensor defect

Error E3.04
- is undelayed with the switch on,
- is indicated during operation after approx.
15 secs.
