NOTE: Two-Way valve operation described. For a three-way valve, A to AB
operation is the same. B to AB operation is opposite that of A to AB operation.
Wiring and Wiring Diagrams
Make all connections according to job wiring diagrams and in
compliance with local and national electrical codes. Refer to
diagrams for typical wiring.
NOTE:
• Multiple actuators may be connected to a single controller
• Do not exceed the maximum current draw of the
controller.
• Use only one spring return actuator per 10 VA transformer.
• Use of a properly sized, inherently limited, Class 2
transformer is recommended.
• Use only 18…24 AWG (0.75…0.22 mm
2
) copper wire
for all connectors. When using multiple wires under one
terminal do not exceed 2 wires or 20 AWG wire.
Three-Wire Notice: Spring return floating valves feature a two second delay upon power loss to
prevent the loss of valve position during brief power outages. There is a three-second delay at
power-up control signal). For more information see Guidelines for Powering Multiple Actuators
EN-206 (F-26363).
