Once a lower command is pressed,
the chain rises.
The programming procedure
cannot be activated.
The control panel is powered but
the chain does not move.
Lack of electrical power supply
Incorrect encoder connection
Jumper direction motor inverted
The chain is not completely lifted.
A normally closed input is not
active
Burned fuse
Check the presence of the electrical voltage and all the
connections to the electrical network
Check the connections of the encoder’s wires
Invert the Jumpers.
Lift the chain with the manual procedure. If the chain is
already lifted, turn SW1 to MAN, wait 1 second, turn SW1
to AUT. Try again.
Check the photocell, stop and limit switch input. If not
used they must be bridged to the common.
Replace the fuse with a similar one
