1 OVERVIEW
APC615 Pump Unit Controller is designed for pump systems which controlled by engine. It allows
automatic start/stop, data measurement, alarm protection as well as remote control, remote
measurement and remote communication function. Utilizing the GOV (Engine Speed Governor)
control function, the controller is able to stabilize the outlet/inlet pressure via regulating engine speed.
Besides that, CANBUS (SAE J1939) interface enables the controller to communicate with various
engines which fitted with/not with J1939 interface.
APC615 Pump Unit Controller, reliable and easy to use, fits with LCD display and optional
languages interface (including English and Chinese languages). Simultaneously the exact parameters
of pump unit and engine are indicated by the LCD display on the front panel.
APC615 Pump Unit Controller adopts powerful 32-bit ARM microprocessor technology with
following functions: precision parameters measuring, fixed value adjustment, time setting & set value
adjusting and etc. The majority of parameters can be configured from front panel and all the parameters
can be adjusted and monitored using PC (via RS485 or LINK port). It can be widely used in a number of
pump control systems with compact structure, simple connections and high reliability.
2 PERFORMANCE AND CHARACTERISTICS
Main characteristics are as follows,
132x64 pixel LCD with backlight, multilingual interface (including English and Chinese languages),
and easy operation interface;
Improved LCD wear-resistance and scratch resistance due to hard screen acrylic;
Silicon panel and pushbuttons for better operation in high/low temperature environment;
RS485 communication port enabling remote control, remote measuring, remote communication
via ModBus protocol;
Equipped with CANBUS port and can communicate with J1939 genset. It is not only can monitor
frequently-used data (such as water temperature, oil pressure, engine speed, fuel consumption
and so on) of unit, but also can control start, stop, and rise/drop engine speed via CANBUS port;
With speed regulation function (relay and CANBUS speed control interfaces ), the controller is
able to stabilize the outlet/inlet pressure via regulating engine speed;
Discharge pressure curve and flow curve are user-defined;
6 analog sensors: 2 sensors can switch between resistor type and current type using jumper and
the other 4 sensors can switch among resistor type, current type and voltage type using jumper;
More kinds of curves of temperature, oil pressure, fuel level can be used directly and users can
define the sensor curves by themselves;
Precision measure and display parameters about Engine and pump unit; e.g. engine high water
temperature, low oil pressure, over speed, high water pressure, low water pressure, over flow and
other kinds of fault indication and protection function;
Auto and manual speed regulation functions that can be operated from the front panel of controller
directly;
Idle speed control function;
