Automatic Operation
The CP750 panel features advanced Automatic Start/Stop control which can meet almost any requirement. Two
switch inputs and a transducer input support a number of control scenarios.
Single switch mode allows reliable operation with a single switch. Dual switch operation allows greater hysteresis
when needed.
The transducer input supports simple start/stop operation by level or pressure and maintenance modes with speed
modification.
Programmable high and low set points control start/stop operation.
Level maintenance modes monitor the operating point and adjust the engine speed to match the targeted
set point with configurable aggressiveness.
Dual switch inputs can be combined with the transducer input for redundant safety to protect against
transducer sensor clog or failure.
Throttle Control
The standard
Ramp Throttle
uses a momentary rocker switch to adjust the integral throttle control. All throttle
commands are sent directly to the engine using CANbus throttle control.
Note:
Throttle control requires CANbus throttling to be enabled in the ECU.CANbus throttling is also known as Torque
Speed Control or TSC1.
Other throttle options include
Digital Rotary Throttle
,
Two-State Throttle
(Idle/Run) or
Three-State Throttle
(Idle/Intermediate/Run). The
Digital Rotary
can be installed with the
Throttle Ramp Throttle
or
Three-State
Throttle
to adjust the
Idle
,
Intermediate
and
Run
speeds.
Service Timers
The CP750 display provides sixteen (16) service timers to alert the operator of needed maintenance. The time interval
for each timer can be adjusted in 10 hour increments. A popup message is displayed after the display self test if a
timer has expired alerting the user that service is required. The message is displayed on each power up until the
elapsed timer is disabled or reset.
CANplus Messenger Telemetry Option
The optional
CANplus Messenger
system provides a variety of features to protect and support the equipment
investment. Remote monitoring can alert maintenance requirements, operational problems, improper operation and
location with geo-fence alert. The Web-browser interface allows monitoring an entire fleet of equipment in a central
location. Contact LOFA Industries for more information.
Mechanically Governed Engines
On mechanically governed engines, the
CANplus I/O Board
performs the ECU
function by monitoring low oil pressure, high temperature and two additional engine
faults. Three analog inputs broadcast the oil pressure, engine temperature and fuel
level across the CANbus to the display and other J1939 devices. The engine speed can
be controlled using a mechanical throttle or by using the standard CP750 throttle
controls with the optional
CANplus Actuator Kit
. Automatic throttling with automatic
start/stop requires the use of the CANplus Actuator Kit. Only single speed operation is
possible with a mechanical throttle.
Warning!
When replacement parts are required, LOFA Industries recommends
using replacement parts supplied by LOFA or parts with equivalent specifications.
Failure to heed this warning could lead to premature failure, product damage,
personal injury or death.
