parameters, and view diagnostic troubleshooting
messages.
2. Circuit Breaker ON Lamp — Illuminates (green) when
the main circuit breaker contacts are closed.
3. Circuit Breaker OFF Lamp — Illuminates (red) when
the main circuit breaker contacts are open.
4. Low DEF Level Lamp — Illuminates (blue) when the
DEF level drops below 15%.
5. Pilot Lamp — Illuminates during operation.
6. Control Power Switch — Provides power to the touch
display unit. Place the switch in the ON position for
normal operation. Place in the OFF position when the
generator is not in use.

8. Ethernet Port — An ethernet cable can be plugged into
this port for testing/configuration of the DEIF controller
via a remote computer. For faster data rates this is the
preferred method of communication.
9. Voltage Change-Over Board — 6 jumper plates that
allow the generator to be configured for either 240/208
or 480/460 VAC output. Located inside the control box.
10. Voltage Selector Switch — Use to set the controller's
nominal voltage (240/208V or 480/460V) before
starting the engine. Located inside the control box.
11. Main Circuit Breaker — 3-pole, 800-amp,
motor-controlled circuit breaker. Connects or
disconnects the generator output from the output
terminals. Protects the unit from short circuits or
overcurrent.
12. DEIF AGC-4 Mk II Controller — Provides systematic
control of the generator. Works in conjunction with
the touch display unit. Located inside the control box.
13. Overcurrent Relay — Connected to the main circuit
breaker. If the circuit breaker cannot be reset after an
overload, the Reset button on the overcurrent relay
must be pressed. Located inside the control box.
