Special features

 Timer has been prepared for networking with an Interbus - PMS module, a
Profibus - FMS module or an Ethernet module.
 Timer has been prepared for the control system PSQ6000 XQR.
 When calling up welding programs with electrode nos. 1 through 9, output KSR
selection 1 is simultaneously activated. When calling up welding programs with
electrode nos. 10 through 19, output KSR selection 2 is simultaneously
activated. When calling up welding programs with electrode nos. 20 through 29,
output KSR selection 3 is simultaneously activated. For all other electrode
numbers, the KSR selection outputs are not changed.
 The electrode status outputs „Tip changing prewarning", „End of stepper",
„Dress inquiry", „Initial dressing request" and „New Electrode" correspond to the
status of the electrode that has been assigned to the welding program that was
activated by spot selection.
 The inputs „Tips have been replaced", „Tips have been dressed" and „Dressing
tool has been replaced" correspond to the electrode that has been assigned to
the welding program that was activated by spot selection.
 The „Stop circuit open / no 24 V" fault is automatically reset.
 The DC link voltage is always checked, the fault message is automatically
reset.
 With Initial dressing function
 O09 = „New electrode"
The output becomes high as soon as the welding program selected by spot
selection has an electrode with counter status „0".
 Dressing tool change
The timer has additional counters that count each tip dress performed on each
electrode. These counters may be reset on the programming terminal. If a
counter exceeds a programmed prewarning value, the „Prewarning dressing
tool" output will be set. When the programmed maximum value is reached, the
„End of stepper dressing tool" output will be set.
The function is switched off if the value „0" is specified as maximum value.
 The pressure control valve may be optionally checked at the end of the
squeeze time.
 The „Operate force sensor" serial input status is retransmitted to the analog
output „Operate" (X9.1, 0 = 0V, 1 = 10V).
 The following parallel inputs are retransmitted to serial outputs:
- Motor protection trip
- Flow monitor 1
- Flow monitor 2
- Control sensor 1.1 (2.1)
- Control sensor 1.2 (2.2)
 Fault reset button (since FW-Version -208)
The green fault reset button is used to transform the timer from an error state to
ready state.
 Integrated dressing tool control
The dressing process is started via the "Start dressing tool" input. The timer
