The Dipswitch on the WCC3 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 WCC3
V-Out Relay Board.
If both MODE (SW1-7 and SW1-8) switches are OFF, then the
WCC3 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 selected. If MODE 2 Switch (SW1-7) is
ON, then the V-Out mode is selected. You must cycle power to the
WCC3 V-Out Relay circuit board after setting dip switch SW1-8.
You may select any other dipswitch setting without cycling power
to the board.

SW1-8 MODE 1 (When changing this switch, you
must cycle power to the circuit board)
Binary Output Mode of Operation
When the WCC3 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 8 relays of the WCC3 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 WCC3 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 WCC3 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 (+/- .25 V) minus the
dead band setting that is determined by SW1 dipswitch settings.
These dipswitch settings apply for all 8 inputs and outputs.
When SW1-1 is selected, 1 volt is added to the dead band.
(Dead band = +/- 1 volt)
When SW1-2 is selected, 2 volts are added to the dead band.
(Dead band = +/- 2 volts) (DEFAULT)
When SW1-1 and SW1-2 are 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 SW1-1 are selected, 5 volts are added to the
dead band. (Dead band = +/- 5 volts)
The 8 analog inputs on the WCC3 V-Out Relay board must be
wired to the 8 analog outputs on the SAT III or SAT II Controller
in order for the V-Out mode to function. Also, the 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 24 VAC and GND to power the WCC3 V-Out Relay
Board. 24 VAC polarity must be maintained between the WCC3
V-Out Relay Board and the SAT III Controller. 24 VAC must be
wired to 24 VAC and ground to ground or else damage to the SAT
III or WCC3 V-Out Relay Board could result.
