Follow the procedure step by step to correctly diagnose the problem. In particular, carry out the
checks described in the flowchart with the machine at an elevation between 0 and +15%.
If the motor momentarily starts and stops immediately afterward, there is probably a
problem with the photocell or its cable.
If the machine is locked in one of its travel limit positions, the corresponding limit switch
will be tripped, and therefore the machine will be able to move in only one direction. If
movement in this direction is impeded due to a problem, the message E5 may appear on
the display.
Take particular care with the checks highlighted by circled numbers, which are described in detail
below:
(1) Each LED corresponds to a limit switch. DL1 turns off when the upper limit switch is tripped,
while DL3 turns off when the lower limit switch is tripped. If neither of the 2 limit switches is
tripped and one of the 2 LEDs is off, refer to paragraph 6.8. “The up-down moves in only one
direction”.
(2) Place the tester probes between pins 1 and 2 of connector CN3 on the up-down board. When
the “
↑
” or “
↓
” key is pressed the measured value should be approximately 48 Vdc.
(3) Place the tester probes between pins 12 (ground) and 11 (signal) of connector CN1 on the
CPU board. When the “
↓
” key is pressed the measured value should be approximately 5 Vdc.
Place the tester probes between pins 12 (ground) and 10 (signal) of connector CN1 of the CPU
board. When the “
↑
” key is pressed the measured voltage should be approximately 5 Vdc.
(4) Place the tester probes between pins 4 (ground) and 3 (signal) of connector CN2 on the up-
down. board. When the “
↓
” key is pressed the measured voltage should be approximately 5
Vdc. Place the tester probes between pins 4 (ground) and 2 (signal) of connector CN2 on the
up-down board. When the “
↑
” key is pressed the measured voltage should be approximately 5
Vdc.
(5) Place the tester probes between pins 1 and 2 of connector CN4 on the up-down board. The
measured voltage should be approximately 220 Vac or 110 Vac depending on the type of
mains electricity supply.
(6) Place the tester probes between pins 1 and 2 of connector CN6 on the up-down board. The
measured voltage should be approximately 50 Vdc.
(7) Disconnect the yellow transformer cables on the rectifier bridge and place the tester probes
across the 2 terminals. The measured voltage should be 38 Vac.
(8) Place the tester probes in series with the motor cable. When the “
↑
” or “
↓
” key is pressed the
measured steady-state current should be less than 6 A. To correctly carry out the measurement
procedure refer to 11.3.3. “AC and DC current”.
