4. Using the calculated temperature coefficient: The calculated temperature coefficient can be read out and used
from CANopen object 0x430A/02. The temperature coefficient is only calculated in control mode (ST bit = 1).
Reading back the calculated TCR value must take place during active control operation, i. e. during an active
heating pulse, as the internal measured value of the current heating element temperature is used for the cal-
culation. Errors in the calculation of the temperature coefficient are reported with the value 0 (calculated tem-
perature coefficient too low or no active control mode) or 65535 (calculated temperature coefficient too high).
To use the calculated TCR value, it must be set for the corresponding channel as temperature coefficient in
object 0x400A (temperature coefficient). In addition, the value 11 (variable) must be used in object 0x4000
(alloy/temperature range).
10.16 Signals START 0 and START 1
The setpoints for the 24 VDC start signals are set via the following CANopen objects.
• START 0: Setpoint setting in object 4100
h
/01 (“setpoint 0 [°C]”)
• START 1: Setpoint specification in object 4100
h
/02 ("setpoint 1 [°C]")
The values are not stored retentively and must be initialised again after a restart of the device.
10.17 Date and time in CANopen
The date of the internal clock is represented in CANopen object 4300
h
/00 (“System Date”). During writing, the date
is checked for plausibility. If the date is invalid, writing will be refused. The 32 bit value has the following structure:
The time of the internal clock is represented in CANopen object 4301

is checked for plausibility. If the time is invalid, writing will be refused. The 32 bit value has the following structure:
NOTE
Only very thin sensors must be used for temperature measurement, e. g. ROPEX temperature
sensor TS-2. Thicker sensors, e. g. a PT-100, must not be used. This ensures that the thermo-
dynamic conditions remain constant when closing the welding tools and that the heating ele-
ments are not damaged.
