5 Troubleshooting by event log
5.10 11 xxxx
Continued
Recommended actions
Increase tolerance band, reduce programmed value jumps -
use several programs with different parameters - check
electrode force system - check secondary circuit - increase
tolerance band, ensure constant conditions.
110716, Current is low in consecutive welds, weld
1 to 3.
Description
Task:arg
arg
Current measured is below the limited tolerance band after n
repetitions: - programmed value jump to higher current values
- handling of different sheet thicknesses or sheet layers - variant
electrode pressure conditions - variant resistance conditions
in secondary circuit - mains voltage fluctuations.
Recommended actions
Value jumps - use several programs with different parameters
- check electrode force system - ensure constant conditions -
increase tolerance band, ensure constant conditions.
110717, Weld time is too short, weld 1 to 3.
Description
Task:arg
arg
The permitted time tolerance is not reached - external
termination of weld signal.
Recommended actions
Check setting at Operation - Modify - Programming - Welding
parameters - Time monitoring - check signal.
110718, Weld time is too long, weld 1 to 3.
Description
Task:arg
arg
The permitted time tolerance is exceeded.
Recommended actions
Check setting at Operation - Modify - Programming - Welding
parameters - Time monitoring.
110719, Bosch IO signal error
Description
Task: arg
It is not possible to read the timer status signal, the Bosch timer
I/O unit is lost.

490
Consequences
It will not possible to get the timer status.
Probable causes
The power to the Bosch IO unit is lost or the cable is damaged.
Recommended actions
1. Check the power to Bosch weld timer.
2. Check that the cabling is OK.
110720, Data value outside limits.
Description
Task:arg
Program Ref. arg
The value of 'TimerNo' is outside limits, current value: arg.
Allowed values are: 1 to arg.
Consequences
The instruction will not work until a valid value is entered.
Probable causes
An invalid value was entered.
Recommended actions
Change the value.
Recovery: arg
110721, Empty
Description
Empty
110722, Unknown fault in weld timer.
Description
Task:arg
arg
There is a unknown fault in the weld timer, code arg.
Recommended actions
Connect the BOS5000/6000 application and check the reason
for the fault.
110723, Power unit not ready.
Description
Task:arg
arg
The power unit temperature is too high.
Recommended actions
1. Check cooling.
2. Check duty cycle, load.
