Special features

The welding controller features the following specifics:
 For this timer, the user has to decide whether communication is by means of
the Interbus OPC module or an additional module in the field bus slot. This
decision is made using the existing switch bank (ADR) for the field bus address:
Switch position 0:

Timer is networked via the optical fiber connectors X12 to X15 on the
Interbus OPC module. The timer is an Interbus-S drop with ident. code 229
(decimal). The I/O information is transmitted through the same interface.
Switch position not equal to 0:

Communication is established via an Ethernet adapter in the field bus slot.
The Interbus OPC module is used for I/O communication only, its ident.
code is 47 (decimal).
 Number of electrodes: 9 (electrode no.: 0 to electrode no.: 8)
 The „Stop circuit open / no 24 V" fault is automatically reset.
 The DC link voltage is always verified, the fault message is automatically reset
 Electrode maintenance concept
Output: „Tip changing prewarning" follows the current program selection/spot
selection
Output: „End of Stepper" follows the current program selection/spot selection
Input: "Tips have been dressed" with selection of the electrode no. via program
selection/spot selection
Input: "Tips have been dressed" with selection of the electrode no. via program
selection/spot selection
Especially for electrode change, electrodes 1 through 8:
When an electrode change is acknowledged (via serial input or user interface),
the timer sets output "Counter electrode x reset" for as long until a high level is
detected at the corresponding input "Acknowledge counter electrode x reset".
This sequence can be repeated any number of times. An entry "Electrode has
been replaced" is included in the log provided that the wear counter of the
relevant electrode is not equal to zero.
 Due to timer-internal routines, the minimal preweld/squeeze time is 16 ms.
 The target electrode force is input via 8 bits of the serial I/O array.
Value range: 0 (= 0kN ) to 255(= 12.75 kN); 1 increment = 50N
 For each weld program, values between 0 and 255 can be stored in the timer
for the "sheet thickness" and "sheet thickness tolerance" parameters. The sheet
thickness is output by 8 bits of the serial output array. Outputs are updated in
parallel to the force input update.
