(over current protection); for electrical details see technical data. To connect the device electrically, use the screw terminals on the back of the housing. Figure 5 Electrical connections on the rear: MCU1000EX Relay Mains voltage may be applied to the relay. The user is responsible for ensuring that the maximum current is not exceeded. -
Page 15: Initial Starting
INITIAL STARTING The MCU1000EX is operated via 4 buttons (OK, ESC, UP and DOWN) and a 3-digit 7-segment display. In the basic state, the display shows the current temperature in °C. 1. Connect the temperature sensor Pt100 to the terminals 12 and 13. Connect the actuator to the control output terminals 10 and 11. -
