AMF / ATS
The Auto Mains Failure (AMF) and Automatic Transfer Switch (ATS) features of the controller are very
powerful. There are 3 different AMF / ATS modes.
TERM
DESCRIPTION
Disabled
All AMF / ATS functions are disabled and controller functions as a
standalone genset controller.
AMF
Upon loss of mains the generator will automatically start but no
transferring will take place.
AMF + ATS
Upon loss of mains the generator will automatically start and the ATS
will automatically transfer to generator power. Manual ATS is a
secondary function of AMF + ATS, see below for details.
The following drawing shows a basic diagram of how Auto Mains Failure and Automatic Transfer Switch
work together.
Manual ATS
Manual ATS mode is a way to manually start the generator and change the ATS position. It can only be
used when the AMF / ATS Mode is set to AMF + ATS.
To run the controller in Manual ATS you must first start the generator manually by pressing the RUN
button. Once started you can use the switched inputs 'Transfer to Gen' and 'Transfer to Mains' to
manually change the ATS position.
NOTE
: During Manual ATS mode you can move back to the regular ATS functionality by
pressing the AUTO button. Moving back to regular ATS functionality will disable the 'Transfer
to...' inputs.
