8.7. Check control device

WARNING
Danger from faulty controller
A rough-running control element or a control el-
ement that is stuck in an actuated position may
indicate a faulty controller.
Do not use the product
Have the product repaired
1. Relieve the product PROFI 6 TI.
2. Briefly actuate and release all control ele-
ments of the controls one after the other. The
control elements must return to their initial po-
sitions immediately. The on and off function
must operate without problem.

8.9. Check the braking function

WARNING
Danger from loads crashing
If the chain lags, it may be due to a faulty brake.
The load may fall.
Do not use the product
Have the product repaired
Check without load
Alternately switch your unloaded product
PROFI 6 TI between lifting and lowering
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.
Check with nominal load
Alternately switch your unloaded product
PROFI 6 TI between lifting and lowering
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,
