NITIAL OPERATION
Check with nominal load

Alternatively switch your product
PROFI 3 TI
loaded with a nominal load to lifting and low-
ering
If you release a control device, the chain must
come to a standstill in an acceptable time after
the brake has been applied. For physical reasons,
however, the braking distance cannot have the
value zero. The brake has a response time that is
dependent on the control length. A greater control
length increases this response time.
5.5.4. Check overload protection
WARNING
Danger due to overloading
If the overload protection is set too high, imper-
missibly high stresses may arise if a load exceed-
ing the permissible load capacity is attached.
I
Correctly set the overload protection
NOTICE
The overload protection must only be engaged
briefly in order to prevent unnecessary wear and
overheating of the drive.
The testing of the overload protection is based on
the attachment of test loads.
1. Attach 125% of load capacity. If this load is
lifted, the overload protection setting must be
corrected.
2. Attach 110% of load capacity. This load must
be lifted. A dynamic overload test of 110% of
the nominal load is therefore possible.
3. The overload protection is correctly set.
5.5.5. Check EMERGENCY STOP function
WARNING
Danger from faulty EMERGENCY
