5.3 START/STOP OPERATION
a) Press start key, then engine is cranking;
b) “Preheat Delay XX s” information will be displayed on LCD;
c) After the preheat delay, Starter relay is engaged. If the engine fails to fire during this cranking
attempt then the Starter relay stop outputting; “Crank Rest Time” begins and wait for the next crank
attempt;
d) During the set start attempts, if engine fails to start, it will issue failed to start alarm;
e) In case of successful crank attempt, the “Safety On” timer is activated. As soon as this delay is
over, engine enters into normal running status;
f) During the engine normal running process, when manual throttle is active, users can adjust engine
speed through manual throttle knob;
g) Press stop key, engine enters into stopping process;
h) Engine enters “ETS Solenoid Hold”. ECU power off and ETS delay timer is energized;
i) After ETS delay is over, it enters into “After Stop” delay;
j) Engine is placed into its standby mode after its “Waiting for Stop” delay expired.

HEM8500 Engine CAN Monitoring Controller User Manual Page 17 of 45
5.4 SPEED REGULATION OPERATION
a) After controller normal running, press key (manual throttle is active), controller’s main
screen is showing as bellow,
Speed 800 r/min
Torque 20%
Coolant Temp 35°C
Oil Pressure 100kPa
Battery Voltage 24.5V
Inst. FC 1L/h
Accum. FC 25L
Subtotal FC 25L
Total Time 2:18:25
Subtotal Time 2.3
Manual throttle is active.
Target Speed 800r/min
At Rest
Fig. 3 GOV Interface
Initial target speed value is initial throttle speed value that user-defined.
b) Target speed changes along with regulating throttle knob, then engine speed will be controlled by
the controller on the basis of target speed value. The speed resolution (throttle knob each turn of a
grid) is the setting throttle resolution, if adjusted target speed by throttle knob is over the max
pre-set throttle speed, it will be forced to be equal to the max speed value; if adjusted target speed
by throttle knob is below the pre-set minimum throttle speed, it will be forced to be equal to the
minimum speed value.
c) Press throttle knob, engine target speed value will be forced to be equal to the minimum setting
speed value.
d) Again to press to exit manual throttle mode.

HEM8500 Engine CAN Monitoring Controller User Manual Page 18 of 45
5.5 ENGINE DIAGNOSIS OPERATION
a) Press key to enter into Diagnostic Mode if ECU alarms of controller occur.
b) After system enters into diagnostic mode, if the first ECU alarm is shutdown alarm, engine red light
will flash once at first; if ECU alarm is warning alarm, engine yellow light will flash once at first.
c) After alarm types were indicated, engine detailed fault information can be checked according to the
red light flash frequency, for example, red light first time flashes twice, second time flashes 3 times,
and third time flashes 5 times, then fault code (indicator) data is 235, and corresponding fault
information is low coolant level alarm.
d) If ECU fault occurs, fault information is the same failure, and then the light flashes twice.
e) If there are other ECU alarms, please repeat step b-c.
f) Again press key to exit diagnostic mode.
g) If ECU has no alarms, press key, both engine red light and yellow light are light off.
