Connecting An Encoder (Electronic Limit Switch); Connecting A Mechanical Limit Switch (Microswitch); Connecting Timer Control Limit Switches - DAAB EP104 Instruction Manual

INSTRUCTION MANUAL DAAB AUTOMATIC CONTROLL UNIT EP104 4.08

• Connecting an encoder (electronic limit switch)

EP104 supports DB405 type encoders. The encoder uses the same terminals as a conventional mechanical limit switch. The
two diagrams below illustrate how to connect the encoder, and they also show which is the left and right motor from the point
of view of the automatic control unit. Make sure the cable to the encoder does not share the same buried pipe as the motor
power supply.

• Connecting timer control limit switches

Limit switches can still be used with timer control – they are connected as shown above (mechanical limit switch) but only
for the open position. If there is no limit switch, make the connections as shown below. A mechanical stop in the open
position must be fitted.
