1OVERVIEW
APC715N Engine Pump Controller is used for diesel engine pump unit to realize the start/stop,
speed regulation, data measurement, alarm protection and “four remotes” function of engine pump. It
fits with LCD display, optional languages display (including Chinese, Englishes and other languages).
The exact parameters of engine and pump unit are indicated by the LCD display on the front panel and
the controller is reliable and easy to use.
Utilizing the GOV (Engine Speed Governor) control function, the controller is able to stabilize the
outlet/inlet pressure. Relay, GOV and CANBUS (SAE J1939) interfaces enable the controller to
communicate with various ECU or non-ECU engine pumps.
APC715N Engine Pump Controller adopts 32-bit ARM micro-processor technology with precision
parameters measuring, fixed value adjustment, time setting and threshold setting and etc. The majority
of parameters can be configured from front panel and all the parameters can be set using PC (via USB
port) and can be adjusted and monitored with the help of RS485 port. It can be widely used in a number
of pump control systems (land reclamation pump, fire pump, high-pressure pump, hydraulic pump, mud
pump, plunger pump, etc) with compact structure, simple connections and high reliability

4.4 AUTO START/STOP OPERATION
Auto mode is selected by pressing key; a LED besides the key will illuminate to confirm the
operation.
Auto Start Sequence:
1) When “Remote Start (On Load)” is active, “Start Delay” timer is initiated;
2) When start delay is over, preheat relay energizes (if configured), “Preheat Delay XX s” information
will be displayed on LCD;
3) After the above delay, the Fuel Relay is energized, and then one second later, the Start Relay is
engaged. If the pump unit fails to fire during the “Cranking Time”, then the fuel relay and start relay
are disengaged for the pre-set rest period; “Crank Rest Time” begins and wait for the next crank
attempt;
4) Should this start sequence continue beyond the set number of attempts, the start sequence will be
terminated, the Fail to Start fault will be displayed on LCD;
5) In case of successful crank attempt, the “Safety On” timer is activated, during this period, Low Oil
Pressure, High Temperature, Under Speed and Charge Alternator Failure alarms are inactive. As
soon as this delay is over, “Start Idle” delay is initiated (if configured);
6) During “Start Idle” delay, under speed alarm is inhibited. When this delay is over, “Warming up”
delay is initiated (if configured);
7) After the “Warming up” delay, if engine speed has reached on-load requirements, then the pump
close relay will be energized; pump unit will take load; pump unit will enter into Normal Running
status.
NOTE: In case of “Remote Start (off Load)”, the procedure is the same, except for step No. 7: the pump unit close relay
will NOT be energized, generator will NOT accept load.
Auto Stop Sequence:
1) When the “Remote Start” signal is deactivated while the “Remote Stop” signal is active, the “Stop
Delay” is initiated;
2) Once this stop delay has expired, the Pump Unit Breaker will open and the “Cooling Delay” is then
initiated. Should the Remote Start signal be re-activated during the cooling down period, the unit
will return to running status. Once the “Cooling Delay” expires, the “Stop Idle” delay is initiated;
3) During “Stop Idle” Delay (if configured), idle relay is energized;
4) “ETS Solenoid Hold” begins, ETS relay is energized while fuel relay is de-energized and complete
stop is detected automatically;
5) "Fail to Stop Delay" begins, complete stop is detected automatically;
6) Pump unit is placed into “After Stop Time” after its complete stop. Otherwise, fail to stop alarm is
initiated and the corresponding alarm information is displayed on LCD (If pump unit stopped
successfully after “Failed to Stop” alarm, it will enter “After stop time” and remove alarm);
7) Pump unit is placed into its standby mode after its “After Stop Time”.
APC715N Engine Pump Controller User Manual Page 18 of 72
4.5 MANUAL START/STOP OPERATION
1) Manual Start: Manual mode is selected by pressing key, a LED beside the key will illuminate
to confirm the operation.
Press key to start the unit, it can automatically detect crank successfully, and will
accelerates to high-speed running automatically.
When “Idle Run without Load” is enabled, the unit is idle running when crank succeeds; after the
input port is configured “Manual Load Input” or Water Blast Gun Input” is active, it will enter into
high-speed running with load.
With high water temperature, low oil pressure and over speed during pump unit running, controller
can protect it to stop quickly (please refer to No.2~7 of Auto start operation for detail procedures).
2) Manual Stop: press key to stop the running unit. (Please refer to No.2~7 of Auto stop
operation for detail procedure).
NOTE: In manual mode, users can control the unit on load or off load via input port “Manual on load input”.
4.6 ON-LOAD CONTROL PROCEDURE
When controller is in Auto mode, auto control will be executed during on load procedure. The unit
will automatically take load after normal running and meets the load requirements while automatically
unload when unit stops.
When controller is in manual mode, manual control will be executed during on load procedure.
Whether the unit is on load or off load will by the configuration of input port “Manual Load Input” or
“Water Blast Gun”
“Idle Run without Load” 0: Disable”
Start the pump unit in manual mode and it enters into normal running. The input port is configured
“Manual Load Input” or “Water Blast Gun Input” and it is active, the engine will run on load; when the
input port is inactive, the engine will unload and the unit will keep high-speed running.
“Idle Run without Load” 1: Enable”
Start the pump unit in manual mode and it will keep in idle speed running. The input port is
configured “Manual Load Input” or “Water Blast Gun Input” and it is active, the engine will enter into
high-speed running, and it will take load as soon as the on-load requirements have reached. When the
unit is normal running on load, the input port is inactive, the engine will unload (i.e. the load relay is
deactivated). When the unit enters into high-speed cooling delay, it will enter into idle running after the
the delay ends and then keeps the idle running status.
“Idle Run without Load”2: Only auto GOV enables:
Start the pump unit manually, only in auto GOV mode, the idle running, high-speed running and
loading/unloading will be switched according to the input port status.
APC715N Engine Pump Controller User Manual Page 19 of 72
4.7 ADJUST SPEED CONTROL PROCEDURE
Users can set the outlet pressure as the rated value simply by adjusting the engine speed. The
“Adjust Speed Control” was divided into auto control and manual control.
Manual Adjust Speed: Adjust Speed mode is selected by pressing the key; In this interface,
users can adjust speed using navigational key: , manual adjust speed; , auto adjust speed; ,
manual raise speed; , manual drop speed. “ , manual raise speed” and “ , manual drop
speed” keys are active only when pump unit is normal running under “Manual Adjust Speed” mode.
Auto Adjust Speed: Under this mode, during the unit is normal running, the controller will
automatically adjust the outlet pressure/inlet pressure/engine speed according to the pre-set value to
rated speed and maintain it steadily.
The “Auto Adjust Speed” was divided into relay adjust speed, GOV adjust speed and CAN adjust
speed.
Relay Adjust Speed: Control the engine servo motor simply by using speed raise relay and speed
drop relay.
GOV Adjust Speed: Control the electronic speed regulator simply by using GOV analog signal.
Users should set parameters according to the actual situation as different GOVs have different
parameters.
CAN Adjust Speed: Control the ECU engine speed simply by using CAN interface. According to the
different gain, stability, dead band and acceleration/deceleration rate to control the engine speed.

5MANUAL DPF REGENERATION
5.1 ILLUSTRATION
For engine meeting Emission Standard for Stage IV of non-road mobile machinery, if the
post-processing technology line contains DPF, so it needs the DPF regeneration function.
Usually engine can clear the particulates in DPF by automatic regeneration function. Hower, engine
usually is at short-time state, no-loading running or low load speed running state, automatic
regeneration cannot completely clear out the DPF particulates, and there may appear particulate block,
beyond the limitation. Under this circumstance, manual DPF regeneration operation is needed.
Controller supports manual regeneration function to realize manual DPF regeneration operation.
