F2 fuse seems to be OK but
blows when the elevator tries
to run?
Proceed to Step 2a.
a
Check the brakes and the
wiring:
Unplug XBR3 and measure
the resistance of the brake
coils between pin 1 and 3,
and between 2 and 3.
Typical values for brake coil
resistance are
- for MX5 and MX6:
320 Ohm (+/-20 Ohm),
- for MX10:
220 Ohm (+/-20 Ohm).
Is the measured resistance
below the typical value?
Short circuit in the brake
coil.
Replace the defective brake
module.
b
F2 fuse blows when the
elevator tries to run and the
brake coil resistance
indicates that the brake coil is
OK.
Brake power circuit failure
on V3F16L.
Replace the defective
V3F16L.
