Electrical Connections
The MC12-Micro controller is standard equipped with 3 connections:
1. Mains power cable,
2. Input cable
3. Motor cable
Before switching on the unit for the first time, ensure the mains power voltage being applied is between 80 and 260Vac.
Input (start) signal
The MC12-Micro needs an input signal from the production machine in order to operate.
Two different input signals can be used to control the dosing unit.
1.
A potential free relay contact: Use the white and brown wire for the potential free contact.
2.
A relay signal up to 24 Volt DC: Relay signals can be used for an extruder that has not a tacho signal. In
case of a powered relay signal connect the white wire to +24 VDC and the yellow wire to - side.
