POWER SUPPLY PROVIDES OVERLOAD PROTECTION AND DISCONNECT
MEANS.
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.
IN ML7984, "T5” AND “W” TERMINALS ARE CONNECTED INTERNALLY. DEVICE
IS COMPATIBLE WITH 3 CONDUCTOR WIRING.
USE CONFIGURATION DIP SWITCHES TO SELECT DEVICE FUNCTIONS: DIRECT
ACTING FUNCTION (ACTUATOR STEM MOVES DOWNWARDS WITH SIGNAL
INCREASES TO 10V/20MA) OR REVERSE ACTING FUNCTION (ACTUATOR STEM
MOVES UPWARDS WITH SIGNAL INCREASES TO 10V/20MA).
ALWAYS TURN POWER OFF BEFORE SETTING ANY DIP SWITCHES.
