The PowerZone–DLA is a generator-set controller. It is used on generator sets from Generac, including the MLT4060MVD, MLT4200IV and MLT6.
| Code | Meaning |
|---|---|
| 000192 | Engine down |
| Symptom | Cause | Remedy |
|---|---|---|
| Alarms, warnings, and engine Diagnostic Trouble Code (DTC) faults are displayed. | When an alarm occurs, the controller automatically switches to this screen and remains there until the alarm is cleared. The Stop LED also flashes. | |
| Faulty fuel filter | With engine running and lights off, measure voltage and frequency at the GFCI receptacle. Voltage should indicate 120VAC ± 5%, and frequency should indicate 60.7 Hz ± 5%. If frequency and voltage are both low (<114VAC, <58 Hz), replace the fuel filter. | |
| Faulty generator capacitor | Measure the capacitance of the generator capacitor. If measurement is outside rating (as indicated on the capacitor), replace the capacitor. | |
| Faulty thermostat | Contact a GMASD to replace. | |
| Generator output incorrect | Check the incoming voltage to the ballast driver by checking the available voltage on the GFCI receptacle. Incoming voltage should be 120V ± 5V. | If voltage is incorrect, the generator may require service. |
| High coolant temperature shutdown | Low coolant level | Add coolant if needed. Allow engine to cool, then check coolant level in radiator. Restart engine and check coolant temperature. Stop engine immediately if coolant temperature is 210 °F (99 °C) or more. |
| Incorrect mix/frozen radiator | Thaw the radiator with an external heat source and flush the coolant system with the correct coolant mixture. | |
| Lights not turned on | Inspect electronic control to see if lights are on. Turn lights on. | Turn lights on. If problems continue, contact Generac Mobile at 1-800-926-9768 for assistance. |
| Loose mast cable connector | Verify outside connector is connected properly to inside control box. | |
| Low oil pressure shutdown | Low oil level | Verify oil level on dipstick. Add oil, if needed. |
| Mast lights off, checking inside control box | Loose lighting connections | Inspect the connections inside the control box. |
| Mast lights off, checking inside the control box | Loose lighting connections | Inspect the connections inside the control box. |
| Mast lights off, checking outside the control box | Light fixture is too hot | Allow light to cool 10–15 minutes before restarting. |
| Oil leaking from engine | Inspect the engine for leaks. | |
| Oil pressure switch failure | Refer to OEM engine operator’s manual to identify corrective action. | |
| One or more lights do not turn on | Light breaker tripped. | Inspect light breakers. |
| PAS engaged | Verify PAS is off. | |
| Unit cranks but does not start | Low fuel level | Check fuel level in tank. Verify fuel pump operation. |
| Unit is in STOP mode and flashes | Electrical Trip and Shutdown Fault has occurred | |
| Unit starts but stumbles and dies | Low ambient temperature, Intake heat inoperable, Air in fuel lines, High coolant temperature shutdown | Verify if ambient temperature is within unit limits., Inspect engine air inlet heater function., Purge air from fuel lines., Allow engine to cool. Check coolant level in radiator. Add coolant level if needed., Inspect radiator shroud and ducting for blockage and remove any foreign matter., Inspect for visible leaks. Check tension of water pump drive belt., Contact a GMASD to replace., Remove load on generator and restart engine. Check coolant temperature and shut engine down immediately if it starts to overheat. |
| Water pump failure | Contact a GMASD to replace. |
