Generator control modules
A generator control module handles engine start and stop sequencing, protective shutdowns on fault conditions, and monitoring of engine and alternator parameters, and it is the component that turns a standalone diesel engine and alternator into an automated genset. BPS stocks Deep Sea Electronics control modules including the DSE 7320, along with ComAp controllers, and a general Control Module product covering DSE, Cummins, SmartGen and CAT compatible applications.
When a control module needs replacing, record the exact model printed on the existing unit, DSE and ComAp alone cover multiple distinct series that are not interchangeable, and confirm whether the generator set’s wiring harness and sensor set matches the replacement module’s expected configuration before ordering.
Display screens
The display screen is the operator facing interface, showing the parameters the control module is monitoring, engine temperature, oil pressure, voltage, frequency and active fault codes, and letting an operator start, stop or acknowledge alarms without opening the control panel. BPS stocks a ComAp compatible display screen directly. A display failure is not the same fault as a control module failure, a genset that still runs and protects itself correctly but shows a blank or faulty screen has a display problem, not necessarily a control problem, and the two should be diagnosed separately before ordering a replacement.
Joystick controllers for cranes and manlifts
A joystick controller is the manual input device an operator uses to direct hydraulic or electric functions on a crane, manlift, aerial platform or similar equipment, translating hand movement into an electrical or electro-hydraulic control signal. BPS stocks the Danfoss Joystick 10102151, the Bobcat Joystick Controller 6697905, and several Genie specific joystick and control components including the Genie Joystick 101005 and the Genie Joystick Controller 100840GT.
Joysticks on aerial work platforms are frequently brand and model specific, a Genie joystick is generally not a direct substitute for a Bobcat or Danfoss unit even where the physical grip looks similar, since the internal signal output and connector pinout differ by manufacturer. Confirm the exact model against the platform’s own service documentation before ordering.
Related engine sensors and governors
Two components frequently ordered alongside control modules on Cummins powered gensets are the Cummins Oil Pressure Sensor and the Cummins Speed Control Governor, both stocked directly by BPS. The oil pressure sensor feeds the control module’s protective shutdown logic, while the speed governor regulates engine RPM to hold generator frequency stable under changing load, a fault in either can present to an operator as a generic control module alarm even though the actual failure is in the sensor or governor, not the control module itself.

Common ordering mistakes
- Ordering a generic control module without confirming the exact DSE, ComAp, SmartGen or CAT series printed on the existing unit
- Assuming a display fault and a control module fault are the same problem, when they are diagnosed and replaced separately
- Substituting a joystick from a different equipment brand based on a similar grip shape, without confirming signal output and connector pinout match
- Not checking whether a genset alarm traces back to a sensor or governor fault before replacing the control module itself
Frequently Asked Questions
What is the difference between a generator control module and a display screen?
The control module handles the actual engine start, stop, protection and monitoring logic. The display screen is the operator interface that shows that data and lets the operator interact with it. A faulty display does not necessarily mean the control logic itself has failed.
Can I use any joystick controller on my crane or manlift?
No. Joysticks are typically brand and model specific, a joystick from a different manufacturer usually has a different internal signal output and connector pinout even if the physical grip looks similar. Confirm the exact model against your equipment’s service documentation.
What generator control module brands does BPS supply?
BPS stocks Deep Sea Electronics modules including the DSE 7320, ComAp controllers and displays, and a general control module compatible with DSE, Cummins, SmartGen and CAT configurations.
