Pressure controller REP 6/10
5.4 Power supply for external equipment
The power supply for external equipment is integrated in the controller.
+24V ± 20% max. load current 70mA connection to terminal block "24V"
reference point GND terminal block.
5.5 Operating several fans from one controller
It is possible to connect several fans to one controller. The total control current of the motors must not exceed
the rated current of the controller. If the max control current of the motors is not known, an allowance of 10%
must be added to the rated current of the motors. If the controller's TK motor protection is being used, the
motor thermal switches must be connected in series. This means that all the motors will stop if the thermal
switch in one motor is triggered. If the motors are to be operated individually regarding the thermal switch
motor protection function, each motor should be equipped with a separate motor protection system
(e.g. STET 10).
5.6 Motor protection
The motor is protected by connecting its thermal switches to both TK terminal blocks. The strap across the
terminal blocks must then be removed. If several motors (without separate motor protection) are connected,
the thermal switches must be connected in series.
The controller will be turned off completely once the thermal switches have triggered. The control relay opens
(terminal blocks 11-12 strapped) and the "interference" LED (1) comes on. The protection is reset after
cooling down by cutting the power to the controller with the main switch and then turning it on again. The TK
terminal blocks must be strapped if there are no thermal switches connected to the controller.
5.7 Output voltage 0-10V
Output voltage 0-10 V, I
max
10mA (terminal block „A“ / „GND“) is roughly proportional to the motor
voltage. This can be used, for example, to control another speed controller or a damper motor.
6. Settings
6.1 Setting min. output voltage (P6)
Need only be done as necessary
1. Switch (3) in position "1".
2. Turn the speed potentiometer (P4) to its left-most end position.
3. Set minimum speed by turning (P6) to the desired rpm.
