The connecting HSS cable is available in 1-ft, 1½-ft, 3-ft, 25-ft,
40-ft, 80-ft, and 120-ft lengths. No more than 150 feet of total wire
can be used to power a SAT III HSS loop.
The dipswitch on the WCC III V-Out RELAY board sets the
various modes of operation, and dead band in the V-Out mode.
Dipswitch SW1-7 (MODE 2 - V-Out Mode) and SW1-8 (MODE
1 - Binary Output Mode) selects the MODE of operation for the
WCC III V-Out RELAY board.
If both MODE (SW1-7 and SW1-8) switches are OFF then the
WCC III V-Out RELAY board is in Binary Output mode. Binary
Output 1 to 8 is selected. If MODE 1 switch (SW1-8) is “ON”
then Binary Output 9 to 16 is then selected. If MODE 2 Switch
(SW1-7) is “ON” then the V-Out mode is selected. You must cycle
power to the WCC III V-Out RELAY circuit board after setting dip
switch SW1-8. You may select any other switch setting without
cycling power to the board.
SW1-1 (1) (V-OUT MODE - ADDS 1 VOLT TO DEAD BAND)
SW1-2 (2) (V-OUT MODE - ADDS 2 VOLTS TO DEAD BAND)
(V-OUT MODE DEFAULT SETTING ON)
SW1-3 (4) (V-OUT MODE - ADDS 4 VOLTS TO DEAD
BAND)
SW1-4 (8)
SW1-5 (16)
SW1-6 INVERT (V-OUT MODE) (FLIPS CONDITION OF THE
RELAY OUTPUTS)
SW1-7 MODE 2 (V-OUT MODE) (V-OUT MODE DEFAULT
SETTING ON)
SW1-8 MODE 1 (When changing this switch, you must cycle
power to the circuit board)
Binary Output Mode of Operation
When the WCC V-Out RELAY board is set for the Binary Output
mode (SW1- switch # 8 is either “ON” or “OFF” and SW1 - switch
#7 is “OFF”) the eight relays of the WCC V-Out RELAY board
are controlled by the WCC III program setup of the SAT Binary
Output screens for each satellite controller. SW1- switch # 8 “OFF”
is Binary Output board address relays 1 to 8, and SW1- switch # 8
“ON” is Binary Output board address relays 9 to 16. This assumes
that SW1 - switch #7 is “OFF”.
V-Out Mode of Operation (Hysteresis is
Added to the Setpoint via Setting of the
SW1 Dipswitch)
When the WCC V-Out RELAY board is set for the V-Out mode
(SW1- switch # 7 “ON”), the relay output will turn “ON” when the
input voltage rises above 7.5 VDC (+/- .25V) plus the dead band
setting that is determined by SW1 settings. When the WCC III
V-Out RELAY board is set for the V-Out mode, the relay output
will turn “OFF” when the input voltage drops below 7.5 VDC
(+/- .25V) minus the dead band setting that is determined by SW1
dipswitch settings. These dipswitch settings apply for all eight
inputs and outputs.
When SW1-1 is selected, 1 volt is added to the dead band. (Dead
Band = +/- 1 volts)
When SW1-2 is selected, 2 volts are added to the dead band. (Dead
Band = +/- 2 volts) (DEFAULT)
When SW1-1 and SW1-2 is selected, 3 volts are added to the dead
band. (Dead Band = +/- 3 volts)
When SW1-3 is selected, 4 volts are added to the dead band. (Dead
Band = +/- 4 volts)
When SW1-3 and SW1-1is selected, 5 volts are added to the dead
band. (Dead Band = +/- 5 volts)
The eight analog inputs on the WCC III V-Out Relay board must be
wired to the eight analog outputs on the SAT III or SAT II controller
in order for the V-Out mode to function. Also, the HSS connector
must be connected to the SAT III HSS expansion port for power
and ground connections to the SAT III controller, or a special two-
wire power and ground pigtail must be provided for connection to
24VAC and GND to power the WCC III V-Out Relay board.
