Roller shutter controls
Methods of operation for motor-driven roller shutters.
Key Switch Operation
A key switch requires a key to be slotted into it, and then turned in an 'up' or 'down' direction to control the directional travel of the roller shutter curtain. It must only be configured as a 'hold to run' operator. This means that the key has to be held in the 'on' position to operate the roller shutter.
If you remove your fingers from the key, it should spring back to the neutral position and the travel of the roller shutter curtain will stop. The key can only be removed when it is returned to the 'neutral' position.
Rocker Switch Operation
This is a keyless unit, and is fitted with a sprung switch. The switch will need to be turned (or rocked) in the direction of the indicator arrows or words to control the directional travel of the roller shutter curtain. It must only be configured as a 'hold to run' operator.
The positioning of the unit must be beyond the reach of children.
Push Button control unit
This control unit is often supplied with industrial shutters and is fitted with two buttons controls (knobs) that are pushed in to control the directional travel of the roller shutter; one for 'up', one for 'down'.
Some units also require a key to operate the unit and some are also fitted with a third 'stop' button. It should only be configured as a 'hold to run' operator. If 'impulse' operation is required, additional safety features including a bottom rail safety edge must be fitted. The positioning of the unit must be beyond the reach of children.
Remote Control Operation
This is a wireless hand held unit and has one or more control buttons. It transmits a signal to a receiver positioned next to the shutter which in turn, is wired to the motor. The wireless hand set can be set up so that the button needs to be pressed for the full operation of the shutter (hold to run) or set up so that the button is pressed once (impulse operation).
We recommend that the hand held operator be configured for 'hold to run' operation. If impulse operation is required or the shutter operation cannot be seen by the operator, then additional safety features including a bottom rail safety edge must be fitted.
'Hold to run' configuration
The button will need to be held down for the full travel of the roller shutter curtain in both the 'up' and 'down' direction. It is important that when operating, the travel of the roller shutter curtain is observed at all times. We recommend the fitting of safety devices as detailed below.
The button does not need to be held down, as once pressed, the roller shutter curtain will continue to travel to its upper or lower limit unless the stop button (in some cases the same button) is pressed. Children must not have access to such units. It is important the system is backed up by safety devices to detect persons (or objects) if they are in the path of the operating roller shutter or playing on the roller shutter. See safety devices for roller shutters.
Two or more roller shutters are operated at the same time by one of the operation methods mentioned above. It is often the case with 'group control' that the person operating the controller cannot see the movement of all the roller shutters so it is important that the system is backed up by devices such as photocells or sensitivity edges.
