For reference only! Use the hookup diagram for proper usage.
The YardMaster-5 contains data ports to control external DPDT relays for enhanced operations.
When a stop / go Relay Module is attached to external port 2 it will be automatically sensed on
power up. When sensed the YardMaster will blink ORANGE two times. This indicates that the
STOP/GO relay module has been detected and the YardMaster will operated differently.
The YardMaster will operate as follows when the relay is detected:
When an ALTERNATE sensor is triggered the relay will energize for the programmed
time delay, and then the alternate function will occur. This allows a time delay station stop.
When the FORCE RED sensor is triggered the external relay will energize for the programmed
time delay only. No other switching will occur. This allows an in-between station stop
in a reversing operation.
When the FORCE GREEN sensor is triggered the force green operation will occur as
normal and this relay will not activate.
See the hookup diagrams in this manual for exact operations and details.
When attaching the cable note the location of the red wire and attach as shown. Some cable
assemblies have an arrow on the connector on this wire however this is not always true.
Use the wire color as the guide. If the relay does not operate then try swapping the connector
polarity on the relay.
