F18 drive and MAP panel
Step Action Note
1 Measure the voltage in the
maintenance panel between test pins
TP1 and TP2 on LOP-CB board in MAP
panel. This voltage is equivalent to the
motor current.
Scaling ratio of the measurement:
38 mV corresponds 1 A.
Measuring points on
LOP-CB board:
2 Drive the empty car downwards and
with rated load upwards.
Use rated speed.
Measure these values at same level in
the elevator shaft.
3 Record values. The difference of the measurements
may be about 5 %.
4 If the difference is more than 5 %, recheck the elevator mechanical balancing.
Check also the adjustment of guide shoes or rollers against the guide.
