ENGINE SPECIFICATIONS:
Refer to engine operating and maintenance instructions
** NOTICE **
Regarding Engines - This manual covers the generator portion of
these units. See the separate engine instruction manual for
engine-related problems, detailed engine information and engine
warranty.
** CAUTION **
EQUIPMENT DAMAGE - Be sure to check the engine oil level
frequently as specified in the engine manual.
The following pre-alarm and alarm setting have been pro-
grammed in the DCG:
Pre-Alarm Alarm
Low Coolant Temp (Deg F) 70
High Coolant Temp (Deg F) 210 230
Low Oil Pressure 25 PSI 15 PSI
Overspeed N/A 115%
Battery Overvoltage 15 VDC Enabled
Low Battery Voltage 10 VDC Enabled
Weak Battery Voltage 7.5 VDC Enabled
Coolant Temperature Sender Failure Enabled
Oil Pressure Sender Failure Enabled
Magnetic Pickup Failure Enabled
Battery Chager Failure Enabled
Loss Of Generator Voltage Alarm Enabled
During normal operation the DGC will continuously display the
engine oil pressure, coolant temperature and the battery voltage
reading. By pressing the "Phase Toggle" push-button you can
toggle through the different phases checking the generator output
and amperage reading on each phase.
The DGC has three operational push-buttons. You can tell which
position has been activated by the LEDs positioned just under the
push-buttons:
RUN - Will start the unit locally at the engine generator set and
allow you to proform any necessary checks prior to connecting
your loads.
STOP - Will disable the engine-generator set making it safe to
preform routine maintenance.
AUTO - Will allow the unit to be started from a remote location.
This is the position you will use in conjunction with an Automatic
Transfer Switch. This is also the push-button you depress to
leave the unit in "Standby Mode"
There are three additional LED lights on the panel:
NOT IN AUTO - Indicates that the engine generator set has not
been left in the "AUTO" mode and will not start if there is a line
power failure.
ALARM - This red LED lights continuously during alarm condi-
tions and flashes during pre-alarm conditions.
SUPPLYING LOAD - Indicates the generator is supplying more
than 2% of rated current to whatever is connected to it. In such
cases you should not shut the unit down for routine maintenance
or you will disrupt your loads.
There are seven additional push-buttons on this control panel,
only two of them should routinely be used. The "LAMP TEST"
push-button tests the DCG indicator by exercising all LCD
segments and lighting all LEDs. The "ALARM SILENCE" push-
button would reset an audio alarm if the control is equipped with
one. These controllers are not.
The last five push-buttons, "Raise/Scroll". "Lower/Scroll",
"Select/Enter", "Previous", and Display Toggle, are not used
during normal operation. These push-buttons allow the service
personnel to gain access to some of the programming and
change it in the field. PLEASE NOTE OPENING UP THE
