EQUIPMENT DAMAGE - BEFORE ATTEMPTING TO START
THIS UNIT COMPLETE YOUR PRESTART CHECKLIST AND
INSURE THE GENERATOR MAINLINE CIRCUIT BREAKER IS
IN THE PROPER POSITION PRIOR TO STARTING. STARTING
THIS UNIT WITHOUT IT PROPERLY CONNECTED CAN
CAUSE SERIOUS PERSONAL INJURY OR EQUIPMENT
DAMAGE.
1. Depress the manual mode button on the control panel. The
small LED light next to it should come on.
2. Press the start button- The DSE7310 will send a start signal to
the ECU on the engine. The engine ECU will then energize the
fuel solenoid and start the cranking cycle (10 seconds on and 10
seconds off).
NOTE: There is no start delay in this mode of operation.
If the engine fails to start during this cranking period the starter
motor is disengaged and goes into a rest mode after which a
second attempt is made to start the engine. Should this se-
quence continue through 3 cranking cycles the start sequence
will be stopped and the display will show ‘FAILED TO START’.
All engine functions are controlled by the ECU on the engine.
The ECU on the engine will send information signals to the
DSE7310 via the CAN connections to indicate oil pressure, water
temperature, etc for the display on the engine control.
All shutdown functions are also controlled by the ECU on the
engine, what you see displayed on the DSE7310 display is what
is happening inside the ECU on the engine.
The AC output readings displayed on the DSE7310 are collected
through the AC interface harness wired in the generator control
box. An shutdowns related to the AC output are not a function of
the engine ECU but are based on information collected in the
DSE7310 via this AC harness.
4. During manual operation the load will not normally be applied
to the generator. But caution must be used, if the line power
should fail or be turned off to the transfer switch during manual
operation the load may be applied to the generator.
With the engine running smoothly check the no load voltage and
frequency on the digital display. The voltage should be 208/240/
480 AC depending on which model you have and a frequency of
59.5 To 60.5 hertz (Hz).
If you have the proper voltage at the generator the next step is to
check the voltage at the generator terminals in the Automatic
Transfer Switch. The voltage between the G1 and the G3
terminals should be the same as it was on the generator front
panel. The voltage should also be checked between the hot
terminals (G1 and G3) and the G-N to be certain of a balanced
voltage output and a solid neutral connection. The voltage
between G1 and G-N should be about 120 volts AC (277 on 480
units). The same approximate voltage should be found between
terminals G3 and G-N (120 volts AC).
On three phase panels the G2 voltage level should also be
checked. ON 240 VOLT (DELTA) SYSTEMS BE SURE YOU
KNOW WHERE THE HIGH VOLTAGE “WILD” LEG IS. IT MUST
BE IN THE SAME LOCATION ON THE LINE SIDE AS IT IS ON
THE GENERATOR SIDE. (i.e. if it’s on L-3 on the line side it must
be on G-3 on the generator side.
** Notice **
If for any reason during the check out procedure the voltage and
frequency are not correct, depress the STOP/RESET button and
correct the trouble before proceeding.
5. Stopping – There are two ways to stop the unit when it is in the
manual mode. Pressing the STOP/RESET button will stop the
unit immediately. Pressing the AUTO mode button will stop the
unit but only after the cool down timers have timed out and there
is no remote start signal being sent to the unit.
AUTO MODE
To activate the automatic start mode you will just need to depress
the AUTO button, the LED indicator beside the button confirms
that the unit is in automatic start mode.
To test the automatic start Transfer Switches follow the instruction
in the operator’s manual you received with your transfer switch. If
you get a fault light during the initial start up or prior to start up it
is most likely a false warning light. Simply reset the ATS and
start over.
Once you have completed testing of the ATS, be sure you
ALWAYS leave the system in standby mode unless servicing the
unit. For standby operation, press the AUTO button on the front of
the engine control. The green light should light up next the AUTO
button.
SETTING THE EXERCISER CIRCUIT
For all ATS see the instruction manual shipped with the ATS for
instruction on setting the exercise circuit in your ATS.
