Screwdriver Speed Adjustments; Audible Alarm Settings / Ok And Ng Lights - Bossard 035/E32V Operator's Manual

4.6.8 SCREWDRIVER SPEED ADJUSTMENTS

The controller determines whether a fastener rundown is deemed GOOD (OK) or NO GOOD (NG) by compa-
ring the actual time taken for the rundown cycle to a time window programmed by the user. For example,
a cross threaded screw will cause the screwdriver to shut-off too early (before min time) and the stripped
screw will cause the driver to run too long (beyond max time)
The controller provides two speed control options for the tool – HI/LO running speed and optional slow
start. A running speed of HI or LO may be selected via the rocker switch on the front face of the controller.
Please refer to the screwdriver catalogue specifications for the tool's free speed RPM at the HI and LO
settings.
The controller also has a selectable slow start option. This option can be helpful in engaging screw threads
properly to avoid cross threading. The slow start is intended for initiating the fastener rundown only – the
slow start time must be limited so that the tool switches to full speed before the fastener completed its
rundown.
There are two separate variables for setting up the slow start function – time and speed. Set the slow
start time by entering the desired slow start value (0.0-9.9 sec) for function 'SP'. You can choose between
values of L1-L9 (30% ~ 85% of screwdriver free running speed rpm) or L0 (100%). Exit the program mode
and engage the start (trigger or push) mechanism on the screwdriver to check settings. Repeat until the
desired result is achieved.
Refer to the program flow chart for further details on entering parameters.
4.6.9 AUDIBLE ALARM SETTINGS / OK AND NG
LIGHTS
Along with the two digit count display, the controller also provides visual and audible indication of rundown
OK, rundown NG, and batch complete.
The OK (green) and NG (red) lamps indicate whether the rundown was GOOD of NO GOOD. If the rundown
is within the set parameters, the OK lamp will light up at the end of the rundown. When the fastening batch
is completed, the batch count will display '00' and then reset after a time delay determined by the value
programmed into the END OF BATCH RESET TIMER.
To suit individual user preferences, four variations of the audible alert are available. When active, the
audible alert provides a single short beep for rundown OK, a single long beep for batch complete, three
short beeps for rundown NG (below MIN time setting) and continuous short beeps until the trigger is relea-
sed for rundown NG (above MAX time setting)
The four selectable settings are:
To change the audible alert setting, with the controller in operating mode (not in programming mode),
press the UP and DOWN arrow keys simultaneously. The controller will loop to the next available audible
setting and show the new current audible setting value in the display
