EMERGENCY STOP SWITCH

The generator is equipped with one emergency stop switch, located

on the rear corner of the unit next to the control panel door. The switch

is clearly labeled with “EMERGENCY STOP” and it is red in color. The

switch can be accessed and activated with all doors closed and locked.

Activate the emergency stop switch by pushing the red button in until

it locks down. This will trip the main circuit breaker which will open the

contact disconnecting the load to the connection lugs. This will also

open the fuel circuit, shutting down the engine. The “EMERGENCY

STOP FAULT” will be displayed on the LCD.

The switch will remain closed until it is pulled out.

Use the emergency stop switch only when the generator must be shut down immediately.

For any other shut down, follow the detailed procedure on page 20.

MAIN CIRCUIT BREAKER

The main circuit breaker is located on the main control panel. When the breaker is

in the OFF “O” position, power is interrupted between the customer connection lugs

and the generator. Once the connections have been made to the connection lugs

and the generator has been started and allowed to reach normal operating

temperature, the breaker may be switched to the ON “I” position.

The main circuit breaker will be tripped, disconnecting power to the connection lugs,

if any of the following items occur while the unit is running:

1. Overload of the generator circuits to the connection lugs.

2. The door covering the customer connection lugs is opened.

3. If the emergency stop switch is activated.

Make sure that any problems that cause the main circuit breaker to trip are corrected

before returning the switch to the ON “I” position.

WARNING

The main circuit breaker interrupts power to the customer connection lugs only! The

customer convenience outlets have power even if the main circuit breaker is in the

OFF “O” position. To disconnect power to the convenience outlets, use the individual

circuit breakers located near each outlet.

VOLTAGE REGULATION

The electronic voltage regulator controls the output of the generator by regulating the current into the exciter field.

The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and voltage

roll-off (U/F). The voltage regulator on your unit is adjusted before shipment from the factory. Contact Magnum

Products LLC for additional information before attempting to adjust the voltage regulator.
