ALLOW UP TO 0.5 AMPS FOR EACH DEVICE. ACTUATORS AND
CONTROLLER CAN SHARE SAME TRANSFORMER PROVIDING THE
VA RATING OF THE TRANSFORMER IS NOT EXCEEDED AND PROPER
PHASING IS OBSERVED. DO NOT MIX A.C. AND D.C. POWER SOURCES.

USE CONFIGURATION DIP SWITCHES TO SELECT DEVICE FUNCTIONS:
DIRECT ACTING FUNCTION (ACTUATOR STEM MOVES UPWARDS WITH
SIGNAL INCREASE) OR REVERSE ACTING FUNCTION (ACTUATOR
STEM MOVES DOWNWARDS WITH SIGNAL INCREASE).
5
TURN POWER OFF BEFORE SETTING ANY DIP SWITCHES. FOR
COMMON TRANSFORMER AND COMMON CONTROLLER APPLICATION,
PLEASE CONSULT THE FACTORY.
