Deep Sea Electronics (DSE) Controller Repairs and Replacement
We repair Deep Sea Electronics (DSE) generator controllers on site across Gauteng: blank screens, alarms that keep coming back, sets that ignore a power cut, and replacement modules that need setting up. Many apparent module failures are really the supply, a sender or the wiring, so we test those first. If the module has failed, a suitable DSE unit is fitted, configured to match your generator and proved with a full start, transfer and stop.

How it works
What the DSE module does on your generator
The module runs the start sequence: preheat where fitted, the fuel solenoid, then cranking until it sees the engine has fired, from generator frequency, a speed pickup, oil pressure or the charge alternator. It then watches oil pressure, temperature, speed, battery voltage and the output against its configured limits. DSE modules are fitted to sets built around engines from many makers, Perkins among them; on an engine with an electronic control unit (ECU), the module reads engine data and alarms over a CAN link instead of separate senders.
A mains-failure module also senses the incoming supply. When the mains stays out of limits past its start delay, it starts the set and switches the changeover; when the mains is stable again it transfers back and cools the engine down.
The photo shows where a control module typically sits on a canopied standby set. It is an example of the type of equipment and is not presented as a particular make of module.

Reading a DSE alarm before you reset it
A DSE module grades every alarm. A warning leaves the set running. An electrical trip opens the generator breaker and lets the engine cool down before stopping it. A shutdown stops the engine at once. The level shows how serious the fault is; the text names the input that tripped.
That input is not proof of the cause. A low oil pressure shutdown may be a real lubrication fault, but it can also come from a failed sender, a chafed wire shorting to the block or a sender that does not match the setting, so we compare a mechanical test gauge with the screen before condemning anything. Our controller alarms guide covers the other common alarms.
On site
Faults we trace on DSE-controlled sets
Blank or flickering screen
The module runs from the starting battery. A flat battery, failed charger, blown supply fuse or corroded terminal blanks it or resets it during cranking.
Alarms with nothing wrong
An out-of-range sender, a broken earth or a loose plug on the back of the module raises alarms that look genuine.
Ignores a power cut: ATS and changeover problems
Left in manual or stop after a test, a shutdown alarm still latched, a flat battery, or on an auto-start module an open remote start signal from the transfer panel. A blown mains sensing fuse does the opposite: the module sees a failure that is not there and starts the set. During load shedding these faults often show only at the next outage.
Runs, but no load transfers: Running but no power
The screen shows voltage but the changeover never moves: a switching output, contactor coil, interlock or breaker feedback fault.
Relay and fuse faults
Start and fuel relays, output fuses and the engine loom suffer from heat and vibration.
Wrong settings after a swap: Control panel repairs
A replacement or reset module may have the wrong engine type, sender curves, timers or protection limits.
Replacement
How we replace and set up a DSE module
- 01
Record the set-up
If the old module still powers up, its settings are recorded and the wiring photographed.
- 02
Choose a suitable module
The same model where possible, or one with the inputs, outputs and engine link the set uses.
- 03
Check every terminal
Senders, outputs, emergency stop, current transformers and changeover wiring are checked, not assumed from old labels.
- 04
Configure to match
Engine type, crank disconnect, senders, timers and protection limits are set to suit the engine, alternator and site.
- 05
Prove it by testing
A simulated mains failure, transfer, return and cool-down, plus each protection that can be tested safely.

FAQ
Frequently asked questions
Can I reset a DSE alarm myself?
A warning can be cleared from the front panel once you have photographed the screen. After a shutdown, especially for oil pressure or temperature, leave the set stopped and call us: restarting on a real fault can ruin an engine.
My DSE screen is blank. Has the module failed?
Often not. Press a front-panel button, as some modules are set to switch the screen off when idle, and check that the emergency stop is released. If it stays blank, call us: we test the supply fuse, battery, charger and wiring before suspecting the module.
Can a DSE module replace the old panel on my generator?
Usually. It is a common way to replace an obsolete controller, with senders, wiring and configuration done for your engine; see control panel repairs.
What should I send before you come out?
The set’s make, model and kVA, the DSE model number, the hour-meter reading and a photo of the alarm on the screen.
