3 INITIAL START-UP
m
WARNING:
Before connecting power to hoist, check all “motion” buttons on pendant control
assembly to make sure that they operate freely without binding or sticking. Check
pendant cable and strain relief connection to ensure that they are not damaged.
3.1 Start-Up Procedure
If any problems or malfunctions occur during the start-up, refer to Chapter "Troubleshooting", to find out the
reason. All problems must be solved before continuing.
m
WARNING: High voltages inside device. Wait for at least five minutes after the supply voltage
has been switched off before service actions. Display in operating condition (lights on)
indicates a dangerous voltage on the DC-bus. When display turns off, the DC-bus voltage is
about 100V. Note also that there is a dangerous voltage in the braking resistor always when the
DC-bus is charged.
m
WARNING: Do not connect any voltage to the output terminals (U, V, W). Otherwise, the
inverter will be damaged.
m
WARNING: The overload protection protects both the supply and the motor cables. The supply
fuses provide short circuit protection.
3.2 General
Initial start-up procedures are as follows:
Read all attached WARNING tags and placards affixed to hoist.
Oil load chain generously over entire length of chain.
Make sure that load chain is not twisted. If so, untwist load chain before using.
Make sure fall stop is placed at least 6” [150 mm] from last chain link on free end.
Install chain container.
If furnished, make sure that trolley wheels have proper spacing in relation to beam flange. See
appropriate trolley manual for details.
Check direction of hook travel to make certain that it corresponds to respective control button that is
depressed. That is, does hook travel “ UP” when UP BUTTON is depressed? If OK, go to section 3.4. If
not, proceed to section 3.3 for correcting direction of travel.
