Load calculations
For automatic mains failure (AMF) applications, you can place the current transformer (CT) on the line from the genset or on
the load cable. The load calculations are based on where the CT is placed.
If the location of the CT is on the On Alt Output cable, which means the CT is on the genset side, then the load calculations
are based on the genset load. The calculations do not depend on the breaker output or feedback input.
If the CT is placed on the load cable, then the load calculations are based on these conditions:
• If you have configured breaker feedback for the genset breaker and the mains breaker, then the load calculations are
based on the breaker feedback. For example, if the controller receives breaker feedback from the mains breaker, then
the load calculations are based on the mains load.
• If you have not configured breaker feedback for the breakers, then the load calculations are based on the breaker
output. This is only for a continuous breaker type setting.
• If you have not configured breaker feedbacks and the breaker type setting is a pulse, then the load calculations are
based on the genset load.
• If you have not configured breaker outputs or breaker feedbacks, then the load calculations are based on the genset
load.

Alarms
You can configure warning and notification alarms on the controller. For example, an alarm for low oil pressure or a warning
when the fuel level is low.
An alarm is shown on the display when the measured value is outside the configured limits for that value. The alarm LED
turns red and the sounder alarm activates (if configured). You can see the type of the alarm on the alarms page, and why it
occurred on the engine status page.
To acknowledge an alarm, push the Up
You can configure the time interval for when an alarm can activate. You can select alarms to activate from when the engine
starts, from when monitoring is on, or always. The controller cannot send a start command if a warning, electrical trip, or
shutdown alarm is unacknowledged.

Description
The genset stops immediately and no longer supplies the load. The genset ignores
the cooling down time.
The genset stops supplying the load and the cooling down time starts. The genset
stops when the cooling down has finished.
You must acknowledge the elctrical trip alarm before the controller can send a start
command.
The genset continues to operate when there is a warning. A warning tells the
operator that something has happened during operation.
You must acknowledge all warning alarms before you can start the genset.
The controller shows the message on the display. Genset operations are not
affected.
