CAUTION
Perform the AUTOCAL function only when the tool with the heating element has cooled off (basic
temperature).
Blocking of the AUTOCAL function:
1. The AUTOCAL request cannot be carried out in the first 10 seconds after switching on the controller. During
this time, the controller reports “AUTOCAL blocked” in the output data (AG bit = 1).
2. The AUTOCAL function cannot be executed if the cooling speed of the heating element is higher than 0.1 K/s.
If the cooling speed has fallen below the specified value, the AUTOCAL function can be executed with the AC
bit activated.
3. The AUTOCAL function cannot be executed when the START request is active (ST bit = 1) (“HEAT” LED lights
up).
4. The AUTOCAL function cannot be executed when the RESET request is active (RS bit = 1).
5. The AUTOCAL function cannot be executed immediately after the controller has been switched on after error
no. 101…103, 201…203 or 9xx (
section 9.15 "Error messages" on page 49). .
Activating the AUTOCAL function is not possible, if the controller has already worked correctly at least once
after being switched on and if error nos. 201...203 or 9xx have occurred.
If the AUTOCAL function is blocked (AG bit = 1) and there is simultaneously a corresponding request (AC bit = 1),
the AUTOCAL LED blinks quickly (4 Hz).

9.2.2
Start (ST)
With the start request (ST bit), the device-internal target-actual comparison is enabled and the heating element is
heated up to the set SETPOINT temperature. This takes place either until the start request (ST bit) is reset or until
the optional heating time limit has expired. An abortion also occurs if the cyclic CAN communication does not take
place.
The “HEAT” LED on the front panel of the RESISTRON
®
Temperature Controller RES-5009 lights up permanently
during this heating time.
A start request is not processed,
• as long as the AUTOCAL function is active
• the controller is in the alarm state
• the setpoint is not higher than 40 °C or
• the reset (RS bit) is active.
In this case, the “HEAT” LED blinks.
Resetting the start request (ST bit) ends the heating process.
During a warning message with error no. 104…106, 111…114, 211, 302 or 303, the alarm relay is switched when
start request (ST bit) is activated (
section 9.15 "Error messages" on page 49). A heat-up process also does not
take place here.
