INSTALLATION
4.1 PROGRAM CARD PROGRAMMING
The diode Program Card provides the means to assign non-conflicting channels and to disable sensing
of Yellow input signals. The card is initially supplied with 120 diodes mounted on the card. This permits
all channels to conflict with all other channels. To program a NON-CONFLICTING (permissive) channel
pair, remove the appropriate diode from the program card. To DISABLE sensing of a Yellow signal on
a channel, solder a wire jumper between the hole pairs labeled for that channel.
Example: If channel 2 Green or Yellow is permissive with channel 6 Green or Yellow, remove
the diode labeled "2-6". To disable Yellow signal sensing on channel 9, a jumper wire must be
soldered in between the pair of holes labeled "9" in the area designated "YELLOW DISABLE"
on the program card.
If the Program Card is removed or not seated properly in the edge connector, the Signal Monitor will
enter the fault mode causing the Output relay contacts to close and enabling the Stop-Time output to
the controller. The PCA indicator will illuminate to indicate this condition. A manual Reset is required
after the Program Card is properly seated.
4.2 WATCHDOG PROGRAMMING
4.2.1 WATCHDOG ENABLE SWITCH
The toggle switch SW2 labeled "WD ENABLE" provides control for the Watchdog Monitoring function.
When the switch is in the ON position, the Watchdog Monitoring function is enabled. When the switch
is in the OFF position, the Watchdog Monitoring function is disabled. The WDT ERROR LED will flash
once every two seconds to indicate that Watchdog Monitoring is disabled.
