GENERAL INFORMATION
1. GENERAL INFORMATION
The electromechanical shaft operator Shaft-50 was designed for automation of industrial sectional doors. The operator can be installed
either on shaft or via intermediate chain-drive (optional).
It consists of a mechanical reducer in “oil bath” and an electric motor with integral control unit. The reducer and the motor have common
casing.
A 3-position control station is connected to the control unit.
1.1. Basic functions
Automatic stop system enables quick and reliable stop of the motor in extreme positions.
A self-blocking reducer mechanically blocks the door shaft when the operator is stopped. In case of a power cut, the door can be operated
by the release lever turned 180° clockwise or by the reducer chain.
Limit switches ensure safe and reliable operation of the operator.
WARNING! Check torsion springs for correct adjustment regularly: if the springs are not adjusted properly, the release can cause
spontaneous closing of the door.
In case of emergency, the door can be operated manually using the chain.
WARNING! Use manual chain without release only in case of emergency; otherwise the chain reducer can fail.

RELEASE OPERATION
6. RELEASE OPERATION
The electric operator Shaft-50 is equipped with a manual chain reducer, which is used for emergency lifting/lowering of the door in case
of a power cut. For emergency control, pull the cord with a red handle down up to the stop to prevent automatic actuation of the operator. To
return to the automatic control, pull the cord with a green handle down up to the stop.
WARNING! It is forbidden to pull down the cord with a red handle, when the operator runs, as this can damage the motor.
WARNING! Intensive regular use of the manual chain reducer is not permitted. Use it in case of emergency only.
WARNING! Using the manual chain reducer, make sure, that the chain links are not deformed or dirty. Otherwise the reducer can
be jammed.
If required, the door can be opened using the chain. Lengthen or shorten the chain so that its assembled edge hangs 50–150 cm above the
floor. It is recommended to fix the lower part of the chain which can be a hindrance to people and equipment. Place the warning labels, showing
closing and opening direction, in plain view.
