12. WCC III INSTALLATION
The “Old” SAT II Type Binary Input with
Time Delay Board - Connection Points
All external connections to the ‘old” SAT II type Binary Input
with Time Delay board connection points are non de-pluggable
screw-cage type of wire-clamped based terminal blocks. With the
exception of the “old” connection method of connecting the Binary
Input with Time Delay board to the SAT III controller which is a
16- pin dip cable connection.
24 VAC & GND (TB2)
The SAT II type Binary Input board requires a 24 VAC power
supply that is connected to these terminals. The SAT II type Binary
Input board is generally powered by the same 24 VAC transformer
that powers the satellite controller. The GND connection points
must be the same between the SAT II type Binary Input board and
the SAT III Controller.
Contact Inputs 1 to 8 and GND
When the contact is closed between one of eight inputs of the
contact inputs connector and ground it will activate one of the eight
LEDs and makes a simulated contact closure on the P1 connector.
This P1 connector is then connected via a 16-pin ribbon cable
to one of the SAT III controller’s former Binary Input dipswitch
locations. This input is automatically kept on for a timed duration
depending on the value of the dipswitch that is located on the “old”
SAT II type Binary Input with Time Delay board.
P1 (Socket Connection to One of the
SAT III Binary Input Former Dipswitch
Locations)
This connector is polarized, and must be properly inserted at both
ends. Pin #1 of the P1 socket must mate with Pin # 1 of one of the
SAT III former dipswitch locations. (The dipswitch on the SAT III
must be removed).
