External Alarm Output (J2, Motor Out & J3, Drive Out)
The Switched B+ or B- may also be used for alarm output if you are not using it for drive
purpose.
One of two outputs can be used for the external alarm. Typically, you would choose to connect
the external alarm between Battery Positive ( PWR OUT ) and the Switched B- ( SW’D B- ) outputs
on J2 . See the diagrams in Figure 21 and Figure 22 for information on how to select these
options.
