Assembly
Install the damper as per instructions for straps or flanges.
Check that the space before/beyond the damper allows the damper blade to be fully opened.
When installing SKPTR with automatic opening and closing function, the risk of personal injury must be
considered. The damper must therefore be installed outside any possible contact zone, for example min.
2.1 m above the floor.
Connecting conduits must be suspended so that the damper is not exposed to destructive forces. These
can cause the damper to jam or stick.
Example of horizontal installation.
Electrical connection
Electrical connection must not be performed before the damper is connected to the pipe system or the
pipe connections are covered in some other way.
Electricity must be connected by a qualified electrician. Connection must be carried out in accordance
with the adjoining diagram.
The motor must, however, be preceded by a multi-pin switch with a break distance of at least 3 mm.

Example of control for automatic damper
Electrical signal to solenoid valve
The solenoid valve on the damper is connected to 230 V or 24 V from the governing process (e.g. a pro-
cessing machine).
Connection:
• Compressed air 5-8 bar is connected by a 6 mm compressed air hose to the solenoid
valve.
• The solenoid valve is connected to the required voltage.
Options:
If the supply voltage from processing machines is 400 V, you must use an EMI-04 transformer in order to
be able to connect the solenoid valve on the damper to the machine. EMI-04 is connected to 400 V and
supplies 24 V AC to the solenoid valve.
Control signal from light sensor
In light sensor EMI-02, a circuit is closed when the sensor is activated by the beam from an arc. Via con-
trol unit EMI-01 the solenoid valve is supplied with 230 V when the sensor is activated. The control unit
contains a potentiometer where damper closing can be delayed by 30 seconds.
Connection:
• Compressed air 5-8 bar is connected by a 6 mm compressed air hose to the solenoid valve.
• The control unit is connected to 230 V and the solenoid valve (230 V) on the damper is connected to
the control unit.
• The light sensor that must be installed close to the light source is connected to the control unit.

Control signal from current sensor
In a current sensor EMI-03 a circuit is closed when the sensor is activated by a suitable electric current.
Via control unit EMI-01 the solenoid valve is supplied with 230 V when the sensor is activated. The control
unit contains a potentiometer where damper closing can be delayed by up to 30 seconds.
Connection:
• Compressed air 5-8 bar is connected by a 6 mm compressed air hose to the solenoid valve.
• The control unit is connected to 230 V and the solenoid valve (230 V) on the damper is connected to
the control unit.
• The current sensor that is to be installed on the power cable to the governing machine is connected to
the control unit.
Commissioning
Check that the damper blade moves easily (must be performed after mechanical installation).
Check that the damper opens and closes as per projected function.
Maintenance
The damper is maintenance free. If necessary, cleaning can carefully be performed.
Spare parts
When ordering spare parts, state damper designation and size. See product plate on damper.
