1.0 INTRODUCTION
The EP6 features Engine and Generating Set control
and monitoring. The EP6 provides visual indication
by means of LEDs (solid state lamps) and a Display
(see section 10.0). It features OFF, MAN and AUTO
operating modes. The display gives Messages for
alarms and Measurement indications.
EP6 has programmable parameters. Please con-
tact the producer of the generating set to receive
instructions related to programming.
2.0 OPERATING MODE selection
The EP6 features AUTO (section 2.1), MANUAL
(section 2.2) and OFF (section 2.3) operating modes.
When the power supply is switched on, the EP6
behaves as follow:
A) if the KEY-SWITCH is in the OFF position, the
EP6 enters the OFF operating mode.
B) if the KEY-SWITCH is in the ON position, the EP6
enters the AUTO operating mode. That is, if the
EP6 was in AUTO prior to the supply removal. If
not, the EP6 enters the MANUAL operating mode.
2.1 AUTO operating mode
To enter the "AUTO" operating mode use the follow-
ing instructions:
A) - Turn ON the key switch: the Display and LEDs
illuminate for 1 second.
B) - Wait for the end of the LAMP test, then push the
AUTO pushbutton after the [UUUU] (Pre-glow)
or [Sta-] (Start prompt) has been displayed. Af-
ter this, the yellow Led AUTO will illuminate. If
the REMOTE START input is not operative, the
LED will ash. If operative, the LED illuminates
continuously and a start cycle will take place
(NOTE: the EP6 shuts down the display during
the crank).
C) - In order to cancel the AUTO operating mode,
push the AUTO pushbutton (the yellow Led will
turn OFF) or turn the KEY-SWITCH to OFF.
Once in AUTO, the EP6 waits for a REMOTE
START activation (see section 7.0).
In case of an Automatic Periodic Test (A.P.T.),
the display will show the message [tESt].
2.2 MANUAL operating mode
To start the engine follow the instructions:
A) - Turn ON the KEY-SWITCH; the EP6 illuminates
the LEDs and Display.
B) - If the display shows the message [uuuu], the EP6
is counting the PRE-GLOW time; wait until the
message disappears.
C) - After the display shows the ashing message
[StA-] (NOTE), turn the Key to START position
(momentary position with spring-loaded return)
until the engine starts. The message [ . . . .] in-
dicates a MANUAL start.
D) - To stop the engine, turn the KEY SWITCH to
OFF.
NOTE: EP6 shows the blinking [StA-] message
for 20 seconds. After this time, if the engine does
not start, the EP6 displays the message [FAIL]
(Fail to start, see section 4.07).To clear the alarm,
turn the KEY-SWITCH to OFF.
2.3 OFF operating mode
This function is obtained by turning the KEY SWITCH
to OFF. The OFF operating mode clears the fault
alarms and shuts down the Display after 5 seconds.
A blinking dot indicates the presence of the power
supply. Press one of the pushbuttons to energize
the display. In OFF operating mode, the EP6 allows
reading of the parameters (see section 6.0).
3.0 DISPLAY features
The EP6 features a 4 Digit Display (section10.0) to
show measurements, settings and error messages.
The [UP-DOWN] pushbutton selects one of the fol-
lowing menus:
[AXXX] (*) Generator Current measurement
[UXXX] The Voltage of the Generating Set
[rPM] [XXXX] Speed of the engine
[HXX.X] Frequency of the Generator
[bXX.X] Battery Voltage
[cXX.X] Charger Alternator Voltage
[ h ] [XXXX] HOUR METER (the message [h] ap-
pears for a moment, and then, the counter will be
displayed continuously).
(*): the symbol "X" means a numerical eld.
