6.1.3.B Transmitter LED
The transmitter has an LED on the bottom for diagnostics. The LED should be on when in a two-block
condition or when the weight is lifted. The LED will flash rapidly during a 2-block condition and will stop
flashing after the switch is in a two-block condition for more than 15 seconds. The LED will flash
randomly approximately every 2 seconds when the switch is transmitting. When in sleep mode, the
LED will not flash. When the transmitter is power up (batteries removed and replaced) the transmitter
LED will be on for 1 second to indicate the transmitter is setup for an A2B switch.
6.1.3.C Travel position (optional)
Designed into the transmitter plate is a small hole into which a hook can be installed. This can be used
to fasten the chain. This hook is used to open the switch and put it into a permanent 2-block condition.
This serves 2 functions.
1. It extends battery life.
2. It prevents the lockouts and alarms from engaging and disengaging due to bounce while
traveling.
The system is in permanent lockout and the system will not function until the chain is unhooked.
To use the feature, attach any part of the chain into the hook. When it is desired to use the switch
again, simply unhook the chain to allow the switch to close.
The chain must be unhooked before the crane is operated.
6.1.3.D Transmitter/Switch installation
Install the standoff to the boom head using 2 5/16x3/4” HEX bolts. The hole pattern for the standoff is
the same as that of conventional PAT A2B switches. In most cases the standoff can be mounted in
the same location as the conventional switch.
If not replacing an existing switch, the proper location would be one that allows the switch to rotate
freely without being obstructed by any part of the boom head. It should be mounted close to the dead
end mounting gusset. The switch should normally be mounted on the cab side of the crane.
