Introduction; Function Description - Besam PowerSwing Installation Manual

Introduction

This manual contains the necessary details and instructions for the installation,
maintenance and service of the Besam PowerSwing.
The Besam PowerSwing is suitable for most types of external and internal swing
doors. The operator can be mounted to walls on either side of the door for pull
or push action and is suitable for single or double doors fi tted with butt hinges or
center pivots.
The motor, oil pump and hydraulic unit are combined into a com pact unit mounted
alongside the control unit within the cover. The operator is connected to the door
leaf with a range of different arm systems.

Function Description

The Besam PowerSwing works electro-hydraulically. It opens with an AC-motor
that via a hydraulic unit and an arm system transmits the power to the door leaf.
The closing power is from a coil spring. The movement of the door is controlled
by limit switches and valve screws.
Opening
When an opening impulse is received by the control unit, the motor starts and
the hydraulic unit rotates the drive shaft and arm system (door) with high speed
towards open position. Before fully open position the speed is reduced to low
speed. The door stops and the motor rotation ceases when the selected door open-
ing angle is reached. This open position is kept by a hydraulic valve.
Closing
The spring closing starts when the hold open time has run out. Before fully closed
position the speed is reduced to low speed, which will be kept until the door is
completely closed. The door is kept closed by spring power. To overcome the
resistance of a striking plate a "lock kick" can be adjusted to required level.
