Page 4: Automatic Operation
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. - Page 5 ® 750 Control Panel Operation and Troubleshooting Introduction ® The CANplus 750 (CP750™) control panel is a universal platform to monitor, control and automatically start/stop both electronically and mechanically governed diesel engines. The microprocessor-based, solid-state design uses high power semiconductors instead of outdated electromechanical relays to ensure reliable high current switching. Graphical gauge pages or a single large analog gauge are displayed on the 4.25”...
- Page 6 ® 750 Control Panel Operation and Troubleshooting LOFA Industries for assistance if the fault persists. After the start-up screen is cleared, the display shows readings on its virtual gauges. Initially the analog gauges are displayed but the display uses the last displayed screen on subsequent startups (see Preferred Screen Store for details).

Page 7: Automatic Start/Stop Operation
® 750 Control Panel Operation and Troubleshooting Throttle Control The type of throttle operators installed along with the configured values of Minimum Requested RPM, Idle RPM, Intermediate RPM, Run RPM and Maximum Requested RPM determine throttle operation. The engine speed can be adjusted above Run RPM and below Idle RPM but the requests can not fall below Minimum Requested RPM or above Maximum Requested RPM. - Page 8 ® 750 Control Panel Operation and Troubleshooting When the configured stop conditions exist, the panel reduces the engine speed per the throttle profile and stops the engine. If the configured start conditions exist before the shutdown process is complete the engine will return to the previous speed until the stop condition exists.
- Page 9 ® 750 Control Panel Operation and Troubleshooting Maintain Functions The Maintain In and Maintain Out functions adjust the engine speed to keep the transducer level at the Target Set Point. The Servo Gain adjusts how aggressively the throttle is adjusted while the Servo Delay controls how often the throttle is adjusted.
