Installation & Operation Instructions
DRN4 - V2
GENERAL INFORMATION
The DRN4 is a resistive output motor actuator
interface that accepts several types of DDC system
signals. The DRN4 output is 0 to 135 ohms. The input
signal types are eld selectable by an 8-position DIP
switch. The oating point input accepts two digital
signals, one for increase and the other for decrease.
The oating point full scale rate of change is 55
seconds. Some triac input signals require an
accessory. The DRN4 is supplied in an enclosure that
can be directly mounted to a 1/2 inch knockout on
the motor actuator. Color coded wire leads with
spade connectors are provided for electrical
connections. Some triac inputs require a Triac
adapter kit. Johnson Control triac input signal
requires a 1,000 ohm 1/2 watt resistor and is included
with all DRN4s.
MOUNTING INSTRUCTIONS
Tools needed may include a Phillips screwdriver to
remove actuator cover screws, 3 wire nuts for two
signal and one common wire connections and a
voltmeter for troubleshooting if necessary. Turn o
power to the actuator and remove the actuator
cover. Remove a knock-out on the actuator near the
actuator control terminals. Open the access cover on
the DRN4 and set the switches to the desired mode
of operation. Replace the switch access cover on the
DRN4 and remove the outermost lock-nut from the
DRN4 box connector tting. Feed the DRN4 wires
through the actuator knock-out and the lock-nut.
Tighten the lock-nut onto the DRN4 tting. Connect
the DRN4 leads with spade connectors to the correct
actuator terminals, the external control source and
the power source. Wire nut any unused wire and
replace the actuator cover.
WIRING INSTRUCTIONS
PRECAUTIONS
• Remove power before wiring. Never connect
or disconnect wiring with power applied.
• When using a shielded cable, ground the
shield only at the controller end. Grounding
both ends can cause a ground loop.
• It is recommended you use an isolated
