50 Hz Operation
The MGG450 is capable of operating at either 60 Hz or
50 Hz. This is achievable by changing the basic settings
of the generator, the AVR configuration and the ignition
mode. The basic settings and ignition mode can be
changed by pressing the “50 Hz ON” soft button at the
bottom of the screen (
Figure 3-1 , Item A). Table 3-3
shows the factory values of the settings depending on
whether the button is active or not.

Shut the unit down.
2.
Unlock the button (“50 Hz ON”) with a service
passcode or higher to activate.
NOTE: If the unit is running when the button is pressed it
will open the circuit breaker and initiate shutdown.
The controller will always give a warning as a reminder
that the AVR (Automatic Voltage Regulator) needs to be
configured. This should be cleared once the AVR has
been configured.
The AVR used by the alternator must be reprogrammed
for 50 Hz operation. The AVR is equipped with a type B
USB female port and can be connected using the
EasyReg software provided by Leroy Somer. Once
connected, a 50 Hz file for the MGG450 must be
uploaded to the AVR.
Operation Checks
With engine running, check for the following:
• Fuel leaks. If a leak is detected, stop engine
immediately by pushing STOP on controller. Repair
leak before proceeding.
