...4 ELECTRICAL INSTALLATION
4.2.9 Motorized Valve – Fig. 4.6
A motorized valve with or without feedback requires 2 relays
(common and normally open terminals) to drive the valve in
either direction. Any two relays can be allocated for this
function. Fig. 4.6 A shows two possible combinations.
Note. For valves with position feedback using
low voltage (mV), voltage (V) or current (C), refer
to Fig. 4.5 B, C and F for connections.
