• Any error message displayed is reset
(Note: The error message is not reset until the RESET signal is switched off)
During activation of the RESET signal, the actual value output goes to 0…3 °C (i.e. approx. 0 VDC). This can be
evaluated as feedback by the higher-level controller (e.g. PLC).
Performance of the AUTOCAL function is not interrupted through activation of the RESET signal.
After the RESET signal is switched off, the controller carries out an internal initialisation for about 500 ms. The
next welding procedure can only be started after that.
A fuse Kb possibly used for switching off the control circuit (
 section 6.3 "Power supply" on page 10) must be
securely switched on no later than 200 ms after resetting of the RESET signal (the switching and delay times of
the fuse must be observed). Switching on later results in an alarm message from the controller.
8.7 Measurement impulse duration
The length of the measurement impulses generated by the controller can be set with this parameter. For certain
applications, it can be necessary to lengthen the measurement impulse beyond the standard of 1.7 ms (
 ROPEX
application report).
This parameter can only be set with the ROPEX visualisation software (
 section 8.11 "USB interface for visual-
isation software ROPEXvisual
®
" on page 27).
8.8 Automatic phase correction (AUTOCOMP)
In special welding applications, it may be necessary to compensate the phase displacement between the U
R
and
I
R
measurement signals (  ROPEX application report). Use of the AUTOCOMP function can be necessary here.
The AUTOCOMP function must be enabled for use with the ROPEX visualisation software (  section 8.11 "USB
interface for visualisation software ROPEXvisual
®
" on page 27) (standard setting: AUTOCOMP off).
The following settings are possible:
1.
“OFF” (factory setting)
AUTOCOMP function switched off.
2. “ON”
The AUTOCOMP function is carried out when the AUTOCAL function (  section 8.4 "Autom. zeroing
(AUTOCAL)" on page 21) has been called up quickly twice in sequence. The pause between the end of the
first and start of the second execution of AUTOCAL must be less than 2.0 seconds. The second execution of
AUTOCAL lasts only about 2.0 seconds and contains the AUTOCOMP function.
If the pause between the two executions is longer than 2.0 seconds, the normal AUTOCAL function is carried
out the second time.
