3. INSTALLATION INSTRUCTIONS
3.11 FUNCTION TESTS
AND ADJUSTMENTS
3.11.1 UP-DOWN LIMIT SWITCH
The installed limit switch has the function to
stop lifting in EMERGENCY cases only. In case
of necessity to use it as a normal operational
stop, a further limit switch should be installed
After connection with the main power line,
check that the hook is lifted when the "Up"
button is pressed. If this is not the case, reverse
two phases of the power supply.
This step is extremely important because
the proper operation of the up and down
limit switches depends on it.
Take care to position the up and down limit
switch stoppers at the correct locations on
the limit switch control rod, so that the switch
operates when the hook is at the desired
height.

never exceed the values of Table 7.
Positioned at the "up" limit switch, the block

Table 7, and should be at the distance indicated
in Table 8. For lifting speeds over 8 m/min. this
distance must be increased at least 50mm.
