SAT 3C – WCC III Interface to TUC/RTU Controllers
Figure 12-40: SAT 3C Controller
The system architecture for the WCC III system interfacing with
the TUC/RTU controllers through the SAT 3C is shown below:
The SAT3C - General Information
(SS5004)
The SAT3C Controller has 8 status lights. The functions of these
LEDs are listed below.
SAT REC - This LED will be lit when communications are being
received by the SAT 3C Controller.
SAT XMIT - This LED will be lit when communications are being
transmitted by the SAT 3C Controller.
TUC REC - This LED will be lit when communications are being
received from the TUC/RTU RS-485 Communications Loop.
TUC XMIT - This LED will be lit when communications are being
transmitted to the TUC/RTU RS-485 Communications Loop.
LOCAL SET - This LED will be lit when no communications with
the WCC III-MCD has occurred in at least the last 2 minutes. This
means that this SAT 3C communications loop is not communicating
with the WCC III-MCD. All standalone setpoint control is
dependent on the LOCAL SET parameters that are programmed
into the SAT 3C controller by the user.
STATUS - This LED blinks for every second if SAT 3C is alive.
“C” MODE - This LED will be lit if this Controller is programmed
as a SAT 3C and blinks for every internal calculation loop
completion.
“D” MODE - This LED blinks for every second during power on
delay and blinks every 8 seconds when watchdog is enabled.
SAT ADDRESS DIPSWITCH - There are two dipswitches on
the cover of the SAT 3C controller, one dipswitch sets the address
of the SAT 3C controller. The other dipswitch sets various local
control options.
