 Fault reset of electric motor-driven gun
A new parameter was introduced to modify the timer response to the two
commands "Fault reset with Weld Complete" and "Fault Reset and reweld"
when given by a user interface (versus an input) as follows:
In the event of a default, the timer will respond to the user interface commands
in the same way as to the corresponding input. The faults are reset, and the
corresponding activity (set Weld Complete contact or reweld) is immediately
carried out.
If the corresponding mode has been activated, the timer will not reset the fault
within the timer as a response to the two commands from the user interface, but
will only set the output "Fault reset and reweld ELMO" or the output "Fault reset
with Weld Complete ELMO".
These outputs will be reset if one of the inputs "Fault reset", "Fault reset with
weld complete" or "Fault reset and reweld" becomes high (modified in firmware
version -205).
 Minimum electrode height
There is no response to this input any more as of firmware version -205.
 When a valid spot selection is active at the I/O array, the „Spot selection valid"
output will become high, otherwise it will be low. If no valid spot number has
been specified, the base pressure of program 0 will be output.
 Dresser blade warning is set as soon as only the number of dressings specified
in the "Warning dresser blade" parameter can still be performed until "max. tip
dress cutter counts" is reached (as of firmware version -206).
 Q Stop
(Only as of firmware version -206A, only in connection with UI controller as of
firmware version -404)
This output is set together with the welding fault output in case of a Q Stop
error. Fault reset will reset this output as well.
 The time within the current has to exceed a minimum threshold is adjustable.
If this threshold is not exceeded on average, the sequence is stopped and an
error message occurs (from firmware version -111).
 Disable UIR Mode (from firmware version -212)
If the value of input I23 "Disable UIR mode" is FALSE when starting a weld
schedule, then this function is not active and the schedule will be run with the
regulation and monitoring mode as defined in the UIR settings of the weld
schedule. This concerns the regulation function and the monitoring function.
If a rising edge on input I23 "Disable UIR mode" is perceived before starting a
weld schedule, then this sequence will not run in UIR mode, but in the mode
which is defined in the general program schedule. This refers to both, the
regulation and monitoring parameters.
The input I23 need to remain in high-level until an acknowledgement by setting
Output O23 "UIR mode disabled" is executed. Output O23 will be reset after the
reset of input I0 "Start".
The weld current log will be extended by an additional column in which the user
can identify that the weld had been run in this special mode.
