3. Function
General
The motor control system advantageously replaces the
traditional solution with gear motor. The step motor has
uniform torque across the entire rpm range, in contrast
to gear motors that lose torque at low and high speeds
of rotation respectively. The step motor's constant torque
curve provides an essentially greater operating range
where the speed of rotation can be controlled with preci-
sion. It is therefore possible to control the heat recovery in
an energy-optimum manner and achieve a more accurate
temperature.
The heat exchanger control system is controlled with 0 –
10 V signals.
The step motor is controlled in micro steps with sinusoidal
constant current for ensuring motor shaft rotation with
uniform torque throughout the revolution. This prevents
torque pulses and at the same time provides quieter
operation.
Rotation monitor
The rotation monitor consists of an inductive sensor.
When the rotation monitor is mounted correctly, the sen-
sor's LED flashes yellow each time the detection surface
passes the rotation monitor.
Operation
LED indications
The junction box has 2 integrated LEDs located under the
cover. They are therefore not visible when the cover is
mounted.
The green LED is constantly lit when voltage is supplied..
The red LED is lit if at least one active alarm has been initi-
ated.
Warning
The chassis on the heat exchanger control
system can become very warm!
Warning! Do not repair the heat exchanger con-
trol system at the site. Never attempt to repair a
defective control system unit.
Contact the supplier to obtain a replacement unit.
