Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
If you need to replace the elevation board, reassemble on the new board the chip
installed into the old one, if it is a different version.
(1) The machine is considered to have reached a travel limit when the corresponding limit switch
is tripped. The lower limit switch is tripped when its lever is pressed, while the upper limit
switch is tripped when its lever is released.
(2) If the machine fails to move downward, place the tester probes between pins 4 (ground) and 3
(signal) of connector CN2 on the elevation board: the measured voltage should be
approximately 4.2 Vdc. If the machine fails to move upward, place the tester probes between
pins 4 (ground) and 2 (signal) of connector CN2 on the elevation board: the measured voltage
should be approximately 4.2 Vdc.
