Preparing the Valor for Installation
1.
Unplug the 24-pin harness from the Serial Interface Module.
2.
See Table 6. On the Serial Interface Module, set Switch 7 and Switch 8 on SW2 to
select a method of operation. Each setting is independent of the other.
3.
Plug the 24-pin harness into the Serial Interface Module.

Front/Rear Cutoff or Enable
The operational setting for Front/Rear Cutoff or Enable must be programmed after
Mode and Intersection. The default setting is for Cutoff in which the Front or Rear
LEDs turn off when 12 Vdc (+BAT) is applied to their control wires. In contrast, Enable
turns on these LED modules when +BAT is applied to their control wires. Both the
front and rear LEDs share the same operational setting and are not independent.
To program this feature:
1.
Unplug the 24-pin harness from the Serial Interface Module.
2.
On the Serial Interface Module, move Switch 1 on SW2 to:
• the down (on) position for Front/Rear Enable.
• the up (off) position for Front/Rear Cutoff.
3.
Plug the 24-pin harness into the Serial Interface Module.
NOTE:
When set to Enable, 12 Vdc must be applied to a Mode control wire and the
Front and/or Rear Enable control wire for the light bar to operate.
In a typical installation, if you want only the Rear LED modules to flash in Mode 1, set
the operation for Enable. Connect the green/white and blue/white control wires to
the Mode 2 connection and the orange/black and blue control wires to the Mode 1
connection.
Exiting Program Mode
When you are finished programming patterns, switch the Serial Interface Module from
Operation Mode to Program Mode.
1.
Unplug the 24-pin harness from the Serial Interface Module.
2.
On the Serial Interface Module, move SW2 Switch 6 to the up (OFF) position.
3.
Plug the 24-pin harness into the Serial Interface Module.
