5.4.1 Running noise
When controlling ventilators using electronic voltage regulators, motor noise can occur (due to the
system), which can be troublesome (Phase cutting = series
“ P... ” ).
On fast running ventilators with a high level of air noise, this noise is relatively low. On slow running
ventilators with a low level of air noise, this noise may be dominant in the lower speed range due to
the occurrence of resonance.
For systems where noise is critical, we recommend using our
Fcontrol series frequency converters
with integrated sinusoidal fi lter.
5.5 Motor protection
Attention!
Motor thermostats cannot be connected to these controller. I.e. a separate motor protection is
required. We cannot under any circumstances accept liability for damage to the motors which do not
have the required motor protection. It is recommended that every fan is equipped with a separate
motor protection unit e.g. type S-ET10 (see connection diagram)!
5.6 Sensor connection (E1, E2)
The device has 2 inputs for type TF.. temperature sensors (KTY):
•
For Compartment temperature
– Sensor type TFR (Part.-No. 00089846) in scope of delivery
– Terminals “ E1 ” / “ GND ”
•
For the out door temperaure or separate sensor for shutter or heating
– Input factory setting deactivated
– Terminals “ E2 ” / “ GND ”
– Sensor not in scope of delivery
Danger due to electric current
Never apply line voltage to analog inputs!
5.7 Control output 0 - 10 V (A2, A3)
The unit has two 0 - 10 V outputs:
•
For ventilation shutter
– output 2 Terminals A2 / GND (I
max
10 mA).
– factory setting inverted (10 V..0 V) i.e. .: 10 V = shutter CLOSED, 0 V = shutter OPEN.
•
For slave controller proportional modulation (factory setting) or with reprogramming for heating.
– output 3 Terminals A3 / GND (I
max
10 mA)
– factory setting not inverted
Information
It is not permissible to connect outputs of several devices to each other!
Inverting outputs and setting curve points possible (e.g. for not linear ouput) in IO Setup (see
installation menu).
