: Features a programmable automatic test cycle to ensure the generator is operational during long standby periods. lovato 31 rgam 12 user manual
The is a microprocessor-based control unit designed for the automatic management of standby generating sets. It acts as an automatic transfer switch (ATS) and engine controller, monitoring the mains supply and initiating a start sequence if power failure occurs. Core Functionality If you need the original , do not
The unit features a front panel with a 3-digit display and LED indicators for status and alarms. It acts as an automatic transfer switch (ATS)
: Initiates a trial run to ensure the system is operational without transferring the load unless the mains fail during the test. Functional Features
| Error Code | Meaning | Likely Cause & Solution | | :--- | :--- | :--- | | | Loss of phase L1 on Mains | Blown fuse, loose wire, or utility outage. Check terminal 1. | | Err 04 | Generator frequency too low | Generator engine speed too low. Check governor. | | Err 08 | Phase rotation error | L1, L2, L3 are not in correct sequence. Swap any two phases on the input side. | | Err 12 | Emergency stop active | The external E-stop button is pressed or the NC contact is open. Check terminals 22-24. | | Err 19 | Internal memory failure | Replace the controller. This is hardware failure. | | Err 24 | Generator failed to start | The controller sent a start signal (out 15-16), but after T2+T3, no voltage was sensed on L1’-L3’. Check fuel, battery, and starter motor. |
