5.4 Motor connection
The motor is connected at terminals U1 and U2. Several motors can be connected to the device.
Attention
The maximum total control current (speci
ed for electronic voltage regulation) for all motors
may not exceed the device
’
s rated current.
If the maximum control current for electronic voltage regulation is not known, a supplementary
20 % of the rated motor current must be allowed for.
When controlling motors from other manufacturers, the controllability and the maximum
current for electronic voltage regulation should be requested from the manufacturer.
Information
•
It is recommended that a separate motor protection unit be foreseen for each fan.
•
For motors with thermistors
“
TB
”
e.g. type S-ET10.
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 controllers series
STEPcontrol
,
SINUcontrol
or
Fcontrol
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 (

5.6 Signal or sensor connection (E1 = Analog In 1)
The unit has one-analog input: terminals
“
E1
”
/
“
GND
”
(Analog In 1).
The connection is independent of the programmed operating mode and from the sensor signal
employed.
The internal jumpers must be placed in correct position depending on input signal. Factory setting 0 -
10 V.
•
When connecting
passive
temperature sensors TF.. (KTY81-210) must be paid attention to no
polarity.
•
When connecting
active
sensors attention must be paid to correct polarity, a 24 V DC power
supply is integrated.
•
For sensors in two-wire-technology (4 - 20 mA signal), the connection is made on the
“
+24 V
”
and
“
E1
”
(
“
GND
”
terminal is omitted).
Over DIP 4 an inverting of the input is possible for mode

speed controller.
•
DIP 4 =
|
OFF
|
(factory setting) for signals: 0 - 10 V, 2 - 10 V, 0 - 20 mA, 4 - 20 mA
•
DIP 4 =
|
ON
|
for signals: 10 - 0 V, 10 - 2 V, 20 - 0 mA, 20 - 4 mA
Attention!
Never apply line voltage to analog inputs!
