WARNING
Before starting this installation, ensure that the crane power has been disconnected and that all
applicable safety precautions are followed.
Use the following steps to install the wiring to the receiver board and/or control transfer switch:
1. Disconnect the ‘hot’ input wire X1 from the pendant and connect it to the (X1) terminal 11 of connector
TB1 on the receiver board (A).
2. If you also need 21R14A receiver installation pendant control, connect a wire from the top right lug on the
RADIO/PENDANT transfer switch to the X1 input for the pendant (B).
3. Install a wire (16 gauge) from the ‘X2’ terminal 12 (X2) of connector TB1 to the ‘neutral’ wire from the
Crane Control Power source (C).
4. Install a wire (16 gauge) from the ‘MLC’ terminal 1 (MLC) of connector TB1 to the main line contactor.
This wire will provide a continuous voltage to the ML Coil when the radio is on (D).
Review the steps above to ensure the accuracy of the wiring before applying power to the installation.
Perform 21R14A Installation Testing.
