OPERATOR SHAF T-120 INSTALLATION AND OPERATING MANUAL
2. GENERAL INFORMATION
The electromechanical operator SHAFT-120 of the company “DoorHan” is intended for automation of balanced industrial sectional
gates.
The electromechanical operator SHAFT-120 is a shaft-type operator with reduction gear in “oil bath”.
It consists of a mechanical reducer in “oil bath” and an electric motor with an integral control unit. The reducer and the motor have a
common housing.
A 3-position control station is connected to the control unit. The operator can be mounted either on the shaft or via the intermediate
chain-drive (optional).
The self-locking reducer enables mechanical lock of the gate shaft, when the motor does not work. In case of power disconnection the
emergency manual release with built-in hand chain drive enables manual opening or closing with chains.
2.1 BASIC FUNCTIONS
The automatic stop system enables quick and reliable stop of the motor in close and open positions.
In case of power cut you can release the operator by pulling the red knob and open the gate manually using the chain.
Important:
Check routinely the torsion spring adjustment: when the springs are not adjusted properly, the release can cause
spontaneous closing of the door.
In an emergency case the door can be controlled manually through the chain.
Important:
Use the manual chain without the release only at emergency, otherwise the chain reducer can fail.
Double end switches enable safe and reliable operation of the operator.
