Malfunction
Code
21 LCC Lift-Up Motor EMOT
failure to turn
23 Lift 1 ascent motion failure
20 LCC Transport Motor HMOT
failure to turn
24 Lift 2 ascent motion failure
25 Communications error
Description
The overcurrent detection circuit detects an
overcurrent condition that lasts for a given
period of time while EMOT remains
energized.
Lift-Up Sensor 1 LS1 is not blocked (H) within
a given period of time after EMOT has been
energized (Lift 1 has started moving up).
The HMOT Lock signal is not input for a
given period of time.
Lift-Up Sensor 2 LS2 is not blocked (H) within
a given period of time after EMOT has been
energized (Lift 2 has started moving up).
LCC becomes uncontrollable due to an error
in communications between the LCC and
machine.
