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.
