Attention!
Before opening the housing
please make sure that all poles
are separated from the line
voltage.
5. Tips for fault location
Please check the following points if the controller
does not work faultlessly:
1. Power supply
If the operating control lamp is off, please check the power
supply of the controller.
The controller is protected by one can fuse T4 A, which is
situated at the base/isolation plate and can be replaced by
opening the cover of the housing (spare fuse is enclosed in
one of the accessory bags).
2. Sensor failure
If there is a malfunction due to a sensor defect, the opera-
ting control lamp flashes red and the symbol is shown
on the display. An error code for the concerned sensor is
shown on the display.
Short-circuit: Short-circuit in the sensor wire with
indication of the concerned tem pe rature
sensor(TT). The error code -888.8 is
shown on the display.
Line-break: Interruption of the sensor wire with
indication of the concerned temperatu-
re sensor (TT). The error code 888.8 is
shown on the display.
Clamped Pt1000-temperature sensors can be checked by
a resistance-measuring device. The measured temperatures
can be compared with the resistance values of the table
opposite.

4. Commisioning
Ac power supply must be activated. The controller passes
an initialisation phase in which the operating control lamp
flashes red and green.
If individual conditions require an adaptation of the parame-
ter, please adjust the values accordingly (vgl. 3.3).
