Control Panel Repairs.
From Relays to Controllers.

We repair generator control panels across Gauteng, from a single failed relay to the wiring, sensors and ATS interface that decide whether your set starts and takes the load. If your engine will not start, the load will not transfer or an alarm keeps locking the set out, we find the fault and fix it.

The Service

Generator Control Panel Repair Across Gauteng

We repair the whole generator control panel: the relays, breakers, fuses, wiring, sensors and ATS interface that start your set, protect the engine and hand the load to your building. When the panel fails, the set may not start, may shut down under load, or may run while your building stays on a dead mains supply.

Panel faults range from a single failed part to a fault that runs through the whole system. A start relay, a fuel solenoid relay or an oil pressure sender is a discrete repair. A transfer that never happens, or an alarm that returns after every reset, means tracing signals between the controller, the panel wiring and the ATS. If the fault sits inside the controller module itself, our generator controller repairs service covers the module. To look up a controller brand or an alarm code, see generator controllers and alarm codes.

Panel work sits between electrical and mechanical engineering. Our lead technician, Charlie, holds a Degree in Electrical Engineering and a Degree in Mechanical Engineering and is a Diesel Plant Fitter, so we read a panel fault together with the engine it protects.

We read fault logs, adjust settings, update firmware where the module allows it and replace failed modules on Deep Sea Electronics, ComAp, SmartGen, Datakom and Woodward panels. Our cost guide puts control panel repair or reprogramming at R3,500 to R14,000, and your written quote gives the exact figure before we start.

We finish every control panel repair with a full function test. We run the auto-start sequence, the load transfer and the return to mains, trigger the shutdown protections and check the alarms before we leave site. Your generator has to complete a full operating cycle, not just power up, before we close the job.

What We Fix

Common Control Panel Faults

  • 01

    Failed start relays

    The set cranks but will not start, or will not crank at all with a good battery. A failed start relay or fuel solenoid relay is a common cause, and we replace the part that failed.

  • 02

    Controller fault codes

    Your panel keeps showing sensor alarms, communication errors, over-speed, under-speed or shutdown codes. We read the log and test the circuit each code points to.

  • 03

    Automatic transfer failure

    The set starts but never takes the load, or will not hand back to mains. We test the ATS interface wiring, the transfer signals, the contactor and the controller settings.

  • 04

    Sensor & sender faults

    Faulty oil pressure, coolant temperature or fuel level senders cause nuisance shutdowns, or hide a real fault. We test each sender against a known reading.

  • 05

    Wiring & connection damage

    Corroded terminals, rodent damage, chafed cables and tired breakers inside the panel cause faults that come and go. We trace the wiring and repair it properly.

  • 06

    Controller programming & upgrades

    We correct wrong settings, update firmware where the module allows it, and upgrade older mechanical panels to a digital AMF controller when that suits your installation.

Controller Alarms

What the alarm usually means

Deep Sea Electronics (DSE), SmartGen, AMF and ATS panels all log events. The brand name is less important than reading the alarm correctly.

  • Shutdown alarms

    Low oil pressure, high temperature, overspeed and emergency-stop alarms stop the set to protect it. We read the log and fix the cause before anyone resets it.

  • Start-failure alarms

    The controller called for a start and the engine did not fire. We check the battery, the fuel solenoid and the start-attempt limit.

  • Voltage and frequency alarms

    Under- and over-voltage or low-frequency trips usually point to the AVR, the load or the governor. We test those before suspecting the controller.

  • Sensor and maintenance alarms

    A sender that reads wrongly, or a maintenance-due warning, can block auto-start. We fix the sender or clear the warning correctly so the set starts on its own again.

Our Repair Process

How we approach a control panel fault

  1. 01

    Systematic fault diagnosis

    We read the fault log, test sensors and relays one by one, and trace the wiring until we find the root cause.

  2. 02

    Targeted component repair

    We replace the relay, solenoid, breaker or sensor that failed, so you pay for one part instead of a whole new panel.

  3. 03

    Controller programming & configuration

    We read, adjust and restore settings on Deep Sea, ComAp, SmartGen, Datakom and Woodward controllers, including firmware updates where the module needs one.

  4. 04

    Full function test before handover

    We test the auto-start sequence, load transfer, shutdown protections and alarms with you before we leave site.

Controller Expertise

Controller families seen on Gauteng sets

Your control panel is the cabinet around the controller: the relays, breakers, terminals and wiring that start the set, carry the alarms and talk to the ATS. We repair all of it, and we repair or replace the controller module when that is where the fault sits.

Deep Sea Electronics, SmartGen, ComAp, Datakom and Woodward modules are the ones we see most on Gauteng sets. Send a photo of the controller screen and the panel when you book, and we bring the right software and leads.

  • Deep Sea Electronics

    DSE logs, settings and AMF faults

  • ComAp controllers

    InteliGen and InteliLite panels

  • Woodward systems

    easYgen-style controllers

  • SmartGen and Datakom

    HGM and Datakom AMF modules

Common Questions

Control panel repairs — questions

What is a generator control panel repair?

A control panel repair fixes the cabinet that runs your generator: the relays, breakers, fuses, wiring, sensors and ATS interface around the controller. When the controller module itself has failed, we repair or replace the module as a generator controller repair.

What does a generator controller do?

The controller starts and stops the set, shows its alarms and, on most standby machines, calls for an automatic start when the mains fails. A warning lets the set keep running; a shutdown stops it.

Do you work on DSE controllers?

Yes. We read the Deep Sea alarm exactly as the screen shows it, check what it means for that module, and test the circuit it points to.

Do you diagnose SmartGen faults?

Yes. We record the SmartGen alarm, test the circuit behind it and fix the cause before we reset anything.

Why will the generator not start automatically?

Automatic start needs three things: a charged battery, a controller that sees the mains fail and no latched shutdown. If any one is missing the set stays silent, so we test all three.

Why does the generator run but the ATS not transfer?

Your engine can be healthy while the changeover never leaves mains. We test the transfer signal, the panel wiring and the ATS contactor on isolated switchgear. Never open the panel or the ATS yourself.

How much does a control panel repair cost?

Our cost guide puts control panel repair or reprogramming at R3,500 to R14,000. A single relay costs far less than a new module, and your written quote shows the exact figure before we start.

Can a controller alarm stop the next start?

Yes. Low oil pressure, high temperature, an emergency stop or a failed start can lock the set out until the cause is fixed. We read the alarm before anyone replaces the starter.

Still unsure what the fault is? Call or WhatsApp 082 057 4605 for onsite diagnosis.
