Emergency Run Operation
In normal operation the EMX3 is controlled via a remote two-wire signal (terminals C31, C32).
Emergency Run is controlled by a two-wire circuit connected to Input A (terminals C53, C54). Closing Input A causes the EMX3 to run
the motor and ignore certain trip conditions.
NOTE
Although the Emergency Run satisfies the functionality requirements of Fire Mode, AuCom does not recommend its use
in situations that require testing and/or compliance with specific standards as it is not certified.
CAUTION
Continued use of Emergency Run is not recommended. Emergency Run may compromise the starter life as all
protections and trips are disabled.
Using the starter in 'Emergency Run' mode will void the product warranty.
