3. Set the desired CANopen node address or CAN identifier
(  section 10.3 "Setting the CANopen node address" on page 58 or  section 11.2 "Setting the CAN identifier"
on page 76).
4. In case of CANopen operation, integrate the EDS file into the CANopen master
(  section 10.1 "Electronic Data Sheet (EDS)" on page 56).
5. Start higher-level control and ensure that no values other than zero are sent to the temperature controller.
6. Switch on the line voltage and 24 VDC power supply in any order.
7. After the voltage is switched on, the yellow “AUTOCAL” LED lights up for about 0.3 seconds and displays the
correct switch-on process of the controller. As long as no line voltage is present, this LED blinks slowly (1 Hz).
8. The following statuses can then result:
9. If the heating element is cold, activate the function AUTOCAL in the CANopen/CAN protocol (  section 9.2.1
"AUTOCAL (AC) automatic zero calibration" on page 30).
The yellow “AUTOCAL” LED lights up for the duration of the calibration process approx. 10…15seconds.
During the calibration process, the AA bit (
A UTOCAL a ctive) is set and a voltage of 0 VDC is output on the
actual value output (terminal 17+7). A connected temperature display ATR-x shows 0…3 °C.
After zero calibration is completed, the “AUTOCAL” turns off and the AA bit is erased again. A voltage of
0.66 VDC (in 300 °C range and Autocal temperature = 20 °C) or 0.4 VDC (in 500 °C range) is reached at the
actual value output. A connected temperature display ATR-x must be on the “Z” marking.
If the zero calibration is not successful, the AL bit (
Al arm active) is set and the red “ALARM” LED blinks slowly
(1 Hz). Then the configuration of the controller is not correct (

section 8.2 "Device configuration" on page 21,
ROPEX application report). After the device configuration is correct, perform the zero calibration again.
10.After successful zero calibration, specify a defined temperature over the CAN protocol (setpoint) and set the
start request. The RA bit ( C ontrol a ctive) is now active and the “HEAT” LED illuminated. The heat-up and con-
trol procedure can be observed at the actual value output:
It is functioning correctly when the temperature (i. e. signal change at the analogue output or the actual value
in the CAN protocol) is steady, that is, it does not jump, oscillate or even go briefly in the wrong direction. Such
action indicates an incorrect placement of the U
R
measurement line.
When an error message is issued, proceed according to section 9.15 "Error messages" on page 49.
11.Burning in the heating element (  section 8.5 "Burning in and changing the heating element" on page 25) and
repeat AUTOCAL function.
NOTE
In addition to the yellow LED “AUTOCAL”, if the red LED “ALARM” lights up for 0.3 seconds,
after switching on, the configuration with the visualisation software has been changed for this
controller (
 section 9.8 "USB interface for visualisation software ROPEXvisual
®" on page 45
).
The controller’s configuration must be checked to avoid malfunctions before continuing with
startup.
