POLAR EMC 92 MONITOR error SCAN REFERENCE POINT

[CHOCK]

Hi sir:
Please measure the battery, must be read the printed number in the same battery, 3.3 , if have more or less replace it immediately, with the same kind of battery,

2) Reset the CPU, in the BOARD, has a little black button. and see what happen.

3) if after doing that steps, please clean all electronic for oxide, the edge connectors, with erase pencil for oxide, and then put clean contacts cleaner. !

Good luck.

Hi sir
This message is displayed when the machine is switched on (Menue: "SCAN
REFERENCE POINT") provided any of the following cases applies:
- the machine has been shut off during active backgauge movement
- a machine is switched on for the first time (commissioning)
- CP board has been replaced.
- a function has been selected in menu "PRESET FUNCTIONS".
However, if this condition occurs frequently (or always) without any of the above
conditions applying this suggests that there is a malfunction in data saving when the
machine is switched off (loss of data due to ageing battery or defective CP board).
If this message is issued in operation (not after start-up), when starting a
positioning process it signals a major malfunction or software error. In that case the
data areas for ramp control and for presetting the ramps for backgauge advance
movement have become volatile because of a malfunction or a defective CP
board or have been overwritten due to a software error in the operating program.
to fix this issue try to Scan reference point in order to recalculate the initialization values for drive
control. After that, check functioning of backgauge drive unit in manual /
automatic mode.
- If the malfunction cannot be removed by performing a reference run, a static
defect in the drive unit will be the cause.
Good luck

I have same problem in Polar 137E .When on machine showing "Scan reference position " after scanning reference position and doing measuring calibration
showing 653 error. I had checked in service mode technical data was no more. So how can restore it again. Pl I need help for this

You dont haave another polar like that to compare , i have 115 but it will notbe the same parameters , you can only undestand the logic and try to do your own configuration

Hi Sir:

Please do all this remedy:

- Make a reference run and move the backgauge along the entire width of the
table, if the position of the mechanical reference point switch has been modified
- Check functioning and position of sensor B 341
- Check cabling B 341
- Check position values in service menu "machine data".
- Check / replace pulse generator
- Check /replace SAP- board
- Check /replace CPxx- board .
- Flag for B341 needs to be adjusted correctly (distance and position).
- Check the coupling for spindle extension.
- Is the pulse generator plugged to X23 (Polar 78ES)
- has pulse generator on plug X23 been plugged in? (Polar 78 ES/XS)
- check S1 electrical interlocking of rear-table guard (neither cut nor
backgauge movements are possible)
- Check backgauge motor, electrical connections and it's cabling.
