Hi folks,

We have the problem of zero position shifting in a router ( Multifor 22 -
Posalux make )

This is a driller converted into a router.

While running, the M/C misbehaves without any reason and the zero position
gets shifted resulting in rejection of all the circuits

But if the M/c is turned off and restarted again, M/c behaves normally
without any shift

We have done the following but of no use

      - Checked reader head and scale - found OK

      - Checked +5 V power supply for any ripples - found OK

      - Checked for grounding and voltage between GND and Neutral and found
to be < 1.5 volts

      - Swapped the CPU - 1 and CPU -2 cards along with  memory cards but
found no effects

      - Isolated the vacuum pipe from the M/c by insulating a flexible
hollow type hose as recommended by Posalux but of no use


Kindly suggest a solution to these

Thanx in advance

Madhu
