4.3.3 PANEL MOUNT OPERATOR STATION WITH DISPLAY AT PARK RELAY
The Panel Mount Operator Station provides feedback for the user that the monitor is in the AT PARK position. The Operator station
contains a circuit board that is equipped with a relay that is energized when the monitor is in use and de-energized when the monitor
reaches its fi nal PARK location. The contact rating of the relay is 1 amp @ 30VDC for resistive loads and 0.2 amps @ 30VDC for
inductive loads.
The AT PARK relay has one Form-C contact (common, normally open, normally closed) that can be used. The fi gure below shows
the terminal blocks available for user wiring.

4.3.4 CONTROLLER AREA NETWORK (CAN) COMMUNICATION BUS
This operator station includes a connection header to communicate across a J1939 CAN bus system and allows control of TFT RC
Monitors and TFT RC Valve Under Monitors when a YE-CAN# Multiplex Interface Control is installed (refer to section 4.14).
4.3.4.1 CAN WIRING CONFIGURATION
The Y4E-RP-D operator station needs to have the communication bus wiring relocated from the RS-485 communication bus terminal
block to the CAN communication bus terminal block. Refer to Figure 4.3.4.1

4.3.4.2 CAN BUS TERMINATION
The CAN communication bus must be terminated as per the ISO 11898-2 Controller Area Network Standard. Optionally, the bus can
be terminated inside the Y4E-RP-D operator station by shorting the CAN BUS TERMINATION HEADER, refer to Figure 4.3.4.1 for
the location of the header. There are many standard shunts that can be used to short the Termination Header. TE Connectivity part
number 881545-2 is one example of a compatible shunt for this Termination Header.
