Transformer based controller for 3~ motors
5-step controller inclusive additional functions
for voltage controllable fans
R-DT1... 7KT(G)
Type:
Examples of applications for controlling 3~ fans in 5-steps
Manual 5-step speed change-over of one or more 3~ fans e. g. in:
heat exchangers (as warm-air heaters), hoods, ventilation of rooms.
Via potential-free contact, e. g. of thermostat (type SRE1G), the device can be switched ON / OFF in the preselected step. Thus
simple temperature control is accomplished.
The device includes potential-free and 230 V power on contacts for the connection of gas valves (hoods application) or damper
control motors (see connection example on back).

(terminals „RT”-„RT”).
• Motor protection using thermal contact connection (terminals „TK"-„TK").
Automatic switch-off by motor overt temperature
Restart after cooling the drive unit by switch-off and after that
switch on the mains voltage or by step-switch („reset").
• Switch-off with interlock via potential-free contact
(terminals FS - FS) e. g. for antifreezing thermostat
(restart see motor failure)
• A power on lamp is integrated
• Automatic switch on after power failure
• Additional power on contact

Connection example for damper control motors
Connection of damper control motors (different models) is possible via the potential-free contacts or
via the 230 V contacts of the power on relay. This relay rises, if the device is activated and the fan is
running. By switching off via remote control (terminals „RT”-„RT“) or in case of motor fault the relay
falls off.
For damper control motors with „single-wire-control” connection with constant voltage (also in switch
position „0”) for „damper CLOSE”.
For motors with „single-wirecontrol”
- damper „OPEN”: if fan is running,
230 V at terminal L
- damper „CLOSE”: constant voltage
at terminal L, if fan is not running
(also in switch position ”0”)
AC 230 V
For motors with „spring return”
- damper „OPEN”: if fan is running,
230 V at terminal L
- damper „CLOSE”: via spring return
(if no voltage at L )
For motors with „2-wire-control”
- damper „OPEN”: if fan is running,
voltage at terminal 14
- damper „CLOSE”: voltage at
terminal 12, fan is not running
(also in switch position ”0”)
