OPERATING INSTRUCTIONS
STARTING THE ENGINE/
GENERATOR SET
Once setup procedures are completed, the
generator set is ready to be started. Start the
unit according to the following steps:
• Make sure the GENERATOR VOLTAGE
SELECTOR SWITCH has been set to the
proper range.This switch should be located
above the 3-phase distribution panel.
(DISREGARD IF THE UNIT DOESN’T HAVE
A SELECTOR SWITCH. THIS UNIT IS
PRESET FOR ONE VOLTAGE. SEE NAME
TAG.)
NEVER CHANGE THE POSITION OF THE
VOLTAGE SELECTOR SWITCH WHILE THE
GENERATOR IS RUNNING! THIS WILL
RESULT IN IMMEDIATE DAMAGE TO THE
SWITCH, THE GENERATOR, OR THE
CONNECTED EQUIPMENT. IT MAY RESULT
IN SERIOUS INJURY TO THE OPERATING
PERSONNEL.
• Place the toggle switch in "ON" position then
press the MANUAL ("MAN") BUTTON on the
Cascade Controller. The unit will start an
automatic timing sequence . After the timing
sequence the engine will attempt to start. Make
sure all debris and obstructions have been
cleared from moving parts and electrical
terminals. The generator will only make 3
attempts at starting before it must be reset with
the switch.
NEVER ATTEMPT TO START THE GENERA-
TOR SET WITH ANY OF THE CIRCUIT BREAK-
ERS "ON". THESE BREAKERS ARE LOCATED
ON THE DISTRIBUTION PANEL. STARTING
WITH THE BREAKERS "ON" CAN CAUSE
DAMAGE TO THE GENERATOR.
• Now that the generator set is running, allow five
minutes for warm-up time.
• Listen for any unusual sounds or excess
vibrations that could signal problems and
require immediate shutdown of the unit. Should
unusual sounds be detected, shut the unit
down, and contact TEREX Service.
• Once the engine has been started and running
smoothly, the following gauges should be
monitored. All gauges are located on the control
panel.
• Oil Pressure Gauge - This gauge should read
30 psi or higher.
• Coolant Temperature Gauge -This gauge
should read between 170-200 degrees F.
• Voltmeter - This gauge should read at least 12
volts DC to indicate the diesel engine’s
alternator is charging properly.
• AC Voltmeter - This gauge should reflect the
proper voltage selected for this operation.
• AC Ammeter - The reading on this gauge
should be zero since the main breaker is in the
“OFF” position. Once a load is applied to the
generator, the ammeter will produce an
appropriate reading.
