FUNCTION
1000
2-10 Vdc Direct Acting
1010
10-2 Vdc Reverse Acting
1
POWER SUPPLY PROVIDES OVERLOAD PROTECTION AND
DISCONNECT MEANS.
2
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.
3
IN ML7984, "T5" AND "W" TERMINALS ARE CONNECTED INTERNALLY.
DEVICE IS COMPATIBLE WITH 3 CONDUCTOR WIRING.
4
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).
5
ALWAYS TURN POWER OFF BEFORE SETTING ANY DIP SWITCHES.
