5.8 Enable ON / OFF
Enable ON / OFF (electronic disconnection) and reset after motor fault via potential free contact, terminals
„D1“-„D1“.
♦
Device ON with contact closed
♦
Device OFF with contact open (“Fault“ relay K1 not released, terminals 11-14 bridged)
Display for disconnection: Green LED flashes
No disconnection (isolation) when turned off, in accordance with VBG4 §6.
5.9 Signal connection or sensor connection (Analog IN1, Analog IN2)
PKDT5 has one anlalog input (Analog IN 1).
PKDM.. controllers have 2-analog inputs (Analog IN1 & Analog IN 2)
Input 1 (Analog IN1) terminals “E” or “E1“ and “GND“
Input 2 (Analog IN2) terminals ”E2“ and “GND“
Ensure correct polarity when connecting; a 24 V DC power supply is integrated for sensors. For sensors in two-wire-
technology (4-20 mA signal), the connection is made on the +24 V and ”E1“ or ”E2“ terminals (the GND terminal is
omitted). The connection is independent of the programmed operating mode and from the sensor signal employed.
Place the internal plug (jumper) or sliding switches for the external default signal in the correct position, factory setting
4..20 mA.

Pos 6.1 Programming the operating mode).
5.10 External speed setting (operation as a speed controller)
The signal for selecting the speed is connected to the terminals “E” (E1)and “GND”; be sure to observe correct polarity.
The maximum length of the connecting cable shall be 30 m (screened).
♦
Setting signal
4-20 mA:
switch
“E1” down position
or jumper “
E1.1” and “E1.2” down inserted
♦
Setting signal
0-20 mA:
switch
“E1” middle position
or jumper
“E1.1” and “E1.2” not inserted
0-20 mA signal is possible by connecting in an external
resistor
(
499
Ω
/ 0.25 W) in parallel between the
terminals “E” and “GND”.
♦
Setting signal
0-10 V
or external potentiometer: switch
“E1” middle position
or jumper “
E1.1” and “E1.2” not
inserted
An external speed setting is possible by using a 10 k
Ω
potentiometer connected to the terminals “A“
(+10 V) and GND with pick-off at terminal “E” or “E1”).
5.10.1 Inverting setting signal
With switch 1 to Dipswitch S1 (not inverted by the factory)
Switch 1 OFF = setting signal not inverted (0-10 V, 0-20 mA, 4-20 mA)
Switch 1 ON = setting signal inverted (10-0 V, 20-0 mA, 20-4 mA)
5.10.2 Operation with second setting signal at input „E2“ (special function only for PKDM..)
An input for a second default signal is activated over the switch 7 on Dipswitch “S1”.
Place the internal sliding switch “E2” or jumper “E2.1” and “E2.2” depending on signal in correct position (see input
“E1”).
- Setting signal not inverted
By operation with a second signal the controller works automatically at the higher level of the two analog
inputs (E1 or E2).
- Setting signal inverted
By operation with a second signal the controller works automatically at the lower level of the two analog
inputs (E1 or E2).
