What the Deep Sea 6120 MKII AMF Module does
The DSE6120 MKII gives a standby generator automatic mains-failure operation at an affordable price. It starts the set when the mains fails, signals the changeover, and shuts the engine down safely when mains returns.
It covers the essential engine protections — low oil pressure, high temperature, over/under-speed and charge failure — and suits most small and medium commercial standby installations.
Signs it needs replacing
- The set must be started by hand during power cuts.
- The existing controller is faulty or obsolete.
- Alarms that cannot be read or reset.
