Connecting control wires
Internal (1) or external (2) power supply can be used for the digital
inputs. Analogue control voltage is 0…10 VDC as default. (The AI
jumper must be in voltage ("U") position).
Control terminals
• Conductor size: stranded 0.25…1.5 mm
2
(AWG 23 to AWG 16)
• Tightening torque: 0.25 N·m.
1) Connected internally to frame (earth) through 1 Mohm resistor.
2) Digital input impedance is 1.5 kohm.
Using 0/4…20 mA current signal:
- Change AI jumper to current
("I") position.
- Set AI OFFSET switch to ON
position if 4…20 mA current
signal is desired.
