Motor protection
Motor protection is possible by connecting thermostats
“
TB
”
(thermal contacts) or thermistors
“
TP
”
(PTC).
The jumper on the device circuit board must be plugged according to the used thermal protector (see
fi
gure
terminal compartment).
Motor with thermistors

jumper plugged at bottom (factory setting).
A maximum of six single thermistors (DIN 44081 or DIN 44082) is permissible which are con-
nected in series.

When a connected thermostat or thermistor responds (interruption between the two terminals
“
TB/TP
”
) the device switches off and does not switch back on.

Switch back on after the drive has cooled down, i.e. in case of a connection between the terminals
“
TB/TP
”
, by switching the line voltage off and back on.
5.7
Analog input
“
E1
”
for setting fan speed
The device has an analog input for setting the fan speed. Connection
“
E1
”
/
“
GND
”
(Analog In 1).
The internal jumper
“
E1.1
”
is factory set in the position for a 0...10 V or PWM speed setting signal.
For a 0...20 mA signal the plug
“
E1.1
”
must be replugged.
Danger due to electric current
•
Do not replug the jumper under voltage, observe the safety instructions!
•
Make sure the signal has the correct polarity!
•
Never apply line voltage to analog inputs!
Possibilities for speed setting
