AMF 3.1 USER MANUAL

General Descriptions

AMF 3.1 is a microprocessor-based controller, which monitors single or 3 phase Mains voltage, transfers

the load between the Mains and the Generator and checks for system failures. The unit eliminates the need of

common panel indicators, hence reduces the cost of the Generator panel. AMF 3.1 has 3 operation modes, which

are Automatic, Test and Off modes. The desired operation mode can be set via the buttons located on the front

panel. By pressing the Menu button for 3 seconds, the user can edit and save any parameter among the 425

parameters in the unit. This feature allows AMF 3.1 to be easily adapted to any engine without the need of a

separate unit.

OPERATION MODES

Automatic Operation Modes:

When the Auto Button

is pressed the Generator will enter the Automatic

Operation Mode. In this mode, the 3 phase Mains is constantly monitored against the limits set by the parameter

values shown below.

P036

Mains Under Voltage

P037

Mains Over Voltage

When the Mains is normal, the Load is supplied by the Mains. If the monitored values of the Mains are

outside the limits set by the related parameters and the time period specified by the

“P039 – Mains Failure Delay

Timer” has passed, it means there is a Mains failure. In this case the Mains contactor is opened and the Generator

is started.

Once the Generator has started, the unit will wait for the time period set by the “P018 – General Failure

Delay Timer” and will check for any failures. Then, after waiting for the time period set by “P006 – Generator

Contact Delay Timer”, the Generator contactor will be closed and the Load is transferred to the Generator.

Once the monitored values of the Mains are back and stays within the limits set by the related parameters

for the time

period set by the “P005 – Mains Contact Delay Timer”, the Mains contactor will be closed and the

Load is transferred to the Mains. In the case where the Generator has supplied the Load since the engine started,

the engine will be

cooled down for the time period set by “P007 – Engine Cool-down Timer”. If the Generator has

not supplied the Load since the engine started, the Generator will be stopped without cooling down. In the

Automatic operation mode, if the AMF unit is receiving a signal that the Generator is running although it is not

supposed to, the AMF will try to stop the Generator.

Test Operation Mode:

When the TEST Button is pressed the Generator enters the Test operation mode and the

Generator will start without checking the Mains. In this mode the Generator Contactor Status Button

and the

Mains Contactor Status Button

will become active. If the Generator is running and the Generator Status LED

is constantly lit, the Generator contactor can be checked using the Generator Contactor Status Button

as long

as the Mains contactor is open. The Generator Contactor Status Button

will energize the GCB if it is de-

energized and will transfer the Load to the Generator. If the GCB is already energized, pressing the Generator

Contactor Status Button will idle the Load. The same situation is applicable for the Mains Contactor Status Button

also. If the Mains status LED is constantly lit and the Generator contactor is open, the Load can be transferred to
