Test
Set DIP switch 4 in position — ON — and press the button for test. The signal is controlled by the
potentiometer at constant speed
and not by any signal from the control system.
Adjust
Is activated by setting DIP switch 4 at OFF and DIP switch 5 at ON. Hereby the maximum
revolutions can be adjusted between 50 and 100 % by the potentiometer. Usually, the factory
setting is OK, but with this potentiometer the maximum revolutions can be reduced or increased.

Alarm signal — COM (common)
10
Alarm signal — Relay is normally closed (this is used by the control system from Systemair)
11
Alarm signal — Relay is normally open (this is
not
used by the control system from Systemair)

Control system input is 0 —10 volt DC
13
Control system input — ground

For BUS signal — RS485 — A (green wire from Systemair control system)
18
For BUS signal — RS485 — B (yellow wire from Systemair control system)
19
For BUS signal — ground (white wire from Systemair control system)

Installation of motor that turns rotor and sensor for control of rotation
After assembly of rotor drive belt between rotor and rotor motor as well as sensor for control of rotation must be
installed.
The rotor motor is installed by Systemair before delivery.
The rotor motor is mounted on a motor console plate.
Check that collision between rotor and sensor is
impossible due to the fact that the diameter of the rotor
can vary 2 — 3 cm. Please turn the rotor by hand in order
to verify that the sensor will not be hit by the rotor.
Note:
To activate the signal from the sensor during
rotation of the rotor it is necessary to install a
screw on the rotor. The distance from the
screw to the sensor must
not
exceed 2 mm.
