Operation
8.1
Start, Stop and Reset Commands
The EMX4e can be started and stopped via the digital inputs, remote keypad,
communication network or smart card. The command source can be set via the
Setup Tools, or using parameter 1A
Command Source
.
•
The EMX4e will only accept Start and Reset commands from the
designated command source.
•
The EMX4e will accept Stop commands from the designated command
source, but can be forced to stop by opening the reset input.
•
The programmable input can be used to override the selected command
source (refer to parameter 7A
Input A Function
).
8.2
Command Override
The programmable input (13, 14) can be used to override the command source, for
situations where the normal control mechanism has been lost. Set parameter 7A
Input A Function
to the alternative command source (eg 'Command Override:
Keypad').
While the input is active, the starter will only accept commands from the selected
override source. To restore control to the command source selected in parameter
1A
Command Source
, reopen the input.
8.3
Emergency Mode
Emergency mode allows the EMX4e to run the motor and ignore trip conditions.
Emergency mode is controlled via a programmable input (input A 13, 14 or input B
13, 15) and parameter 7A
Input A Function
/7E
Input B Function
must be set to
'Emergency Mode'. A closed circuit across 13, 14 activates emergency mode. When
the EMX4e receives a start command, it will continue to run until a stop command is
received, ignoring all trips and warnings.
Emergency mode can be used in conjunction with any command source.
NOTE
Although emergency mode operation 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.
