4.12 REMOTE AUXILIARY
INTERFACE CONTROL
(YE-REMAUX)
The Remote Auxiliary Interface Control allows a user to utilize the AUX1 and AUX2 buttons located on the monitor operator station or
any remote operator station. The Interface Control is equipped with two relays that can operate lights, interface to a valve controller
or in some cases operate a valve directly, etc. The contact rating of the relay is 16 amps @ 30VDC for resistive loads and 8 amps
@ 30VDC for inductive loads.
The installer will need to mount the interface control and connect the cable to power and the communication link of the monitor.
NOTICE
The Interface Control provides no overload protection for the device it is controlling. Failure
to provide overload protection will damage relay contacts, which will disable device being
controlled. Provide manual device operation, where necessary, in addition to remote control.
4.12.1 ENCLOSURE MOUNTING
MOUNT ENCLOSURE
WITH (2) 1/4-20 FASTENERS
TIGHTEN SECURELY.
4-1/2"
(114 mm)
2"
(51 mm)
Select proper enclosure location. Enclosure is designed to be
surface mounted and the size is 5” x 3 1/8” (127 x 80mm). Height
of enclosure is 2 3/8” (60mm). Refer to Figure 4.9.1 for mounting
hole dimensions.

4.12.2 ELECTRICAL WIRING
See fi gure 4.0 for typical connections. The 4-conductor cable from the communication interface box needs to be connected to power
(red & black) and to the communication link (blue & white) from the monitor. Refer to Figure 4.2.2 for typical cable preparation.
Each relay has one Form-C contact (common, normally open, normally closed) that can be used.
4.12.3 CONFIGURATION
The two relays on the circuit board can be individually confi gured as AUX1 or AUX2. Also the actuation of each relay can be
confi gured to be momentary or latching. See Figure 4.12.3 for relay confi guration DIP switch settings.
1. Ensure power is OFF to the unit.
2. Remove lid from interface box.
3. Locate DIP switches on board and select confi guration.
4. Replace lid. Verify rubber seal is clean and undamaged. Verify that no wires are caught between lid and box.
