Samson 5179, 5100 operating instructions Connecting the sensors

Connecting the sensors

Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the back panel of the housing.

Connecting the actuators

Connect cables with at least 1.5 mm² suitable for damp locations to the terminals of the control- ler output. The direction of travel needs to be checked at start-up.

￿Set mode switch to (+). Valves must open. ￿Set slide switch to (–). Valves must close.

Connecting the pumps

Connect all cables with at least 1.5 mm² to the terminals of the controller as illustrated in the corre- sponding connection diagram (–> page 92 to 96).
