Fig. 17.10 Connection of relay to H output.
Three-way switching valve
The output may be used for a three-way
switching valve that is controlled:
1. Unipolarly with return spring: such
valve connect to H output of the controller
through a relay, like in Fig. 17.10
2. Bipolarly, right-left rotations (3-wire
control):
Neutral conductor is connected
directly to the valve, while wires that control
direction of rotations are connected via a
relay and its contacts to relevant terminals.
Status relations on
H outlet and respective
direction of the valve switching are presented
in application schemes.
Change of rotation direction switching will
cause incorrect operation of the unit.
Fig. 17.11 Connection of three-way, bipolarly controlled
valve to H output
If the valve has grounding terminal, connect it
directly to the valve.
Connection of other valve types than
specified above may lead to undesired
operation and is not recommended.
