early, the function is blocked.
2. The AUTOCAL function is not executed when the cooling speed of the heating element is more than 0.1 K/s.
With an activated control signal, the function is automatically carried out if the cooling speed has fallen below
the above-named value.
3. The AUTOCAL is not executed (LED “HEAT” lights up) in case of an activated START signal (24 VDC).
4. The AUTOCAL is not executed in case of an activated RESET signal (24 VDC).
5. Directly after the controller is switched on, the AUTOCAL cannot be performed if the error numbers
101…103, 201…203 or 9xx are not executed (
section 8.16 "Error messages" on page 29). If the controller
worked correctly – at least once – after being switched on, the AUTOCAL function cannot be activated if the
error numbers 201…203 or 9xx appear.
If the AUTOCAL function is blocked and there is a corresponding demand, the related yellow LED flashes.

START signal (HEAT)
With activation of the START signal, the device-internal target-actual comparison is enabled and the heating ele-
ment is heated up to the set SETPOINT temperature. This takes place until the signal is switched off.
The “HEAT” LED on the front panel of the RES-5007 lights up permanently during this time.
The START signal is activated through a 24 VDC signal to the terminals 6+13.
During execution of the AUTOCAL function or when the RESET signal is active, activation of the START signal is
not accepted.
The setpoint specification for the welding temperature must be greater than 40 °C. If this is smaller, the heat-up
process is not started (LED “HEAT” flashing).
During a warning message with error no. 104…106, 111…114, 211, 302 or 303, the alarm output is switched on
when the START signal is activated (
section 8.16 "Error messages" on page 29). A heat-up procedure also
does not take place.
8.6
RESET signal
The RESISTRON
®
temperature controller RES-5007 can be reset through the external RESET signal
(terminal 7+13). Here:
• An ongoing welding cycle is interrupted
• No additional measurement impulses are generated
