Pulse Input Terminal Block (LABELED TB1)
This 10-position terminal block is connected to the Pulse meter(s)
output. There are eight input connections and two ground terminals
provided for ground connections. See Figure 18-5.
Output LEDs
PULSE 1 to PULSE 8 LEDs. These LEDs are not physically
connected to the actual high speed binary capture inputs. They are
software controlled outputs from the microprocessor that is on the
SAT 3P controller. This enables true output status to be displayed
of the actual pulse inputs.
STAT LEDs
There are two STAT LEDs—STAT REC and STAT XMIT.
Whenever the microprocessor transmits a communications packet,
the STAT XMIT LED will be “ON”. Whenever the microprocessor
receives a communications packet, the STAT REC LED will be
“ON”. The STATUS LED blinks out a heart beat status of the SAT
3P controller.
LOCAL SET LED
This LED is normally off, but when the SAT 3P is not
communicating to the WCC III – MCD, this LED will be “ON”
solid.
Option Switches
TEST Switch—When this switch is “ON,” then the SAT 3P
will operate to any input condition that has the word “TEST”
programmed into the setpoint.
LOCAL Switch—When this switch is “ON,” then the SAT
3P operates to the LOCAL SET conditions. Also the SAT 3P
controller will operate in the LOCAL SET conditions when it has
lost communications to the rest of the WCC III communications
loop. This Local set condition should be indicated by the LOCAL
SET LED being “ON”.
L DIS Switch—When this switch is “ON,” then the SAT 3P will
not operate to the LOCAL SET conditions. It should control to
setpoints that are based on the “ON” schedule.
OPT 1, OPT 2, OPT 3 switches—These three switches are not
used at this time.
Mounting Holes
Use the three supplied sheet metal screws to mount the SAT 3P
controller in a suitable enclosure. You must use all three screws to
mount the SAT 3P controller.
