CBE PL3-ST
Official technical documentation and workshop diagnostics for PL3-ST.
Reference
- 1 Mains' general button ON/OFF (to turn on/off press for 2 seconds). LED flashing indicates that the battery is low and that the low voltage device will turn on. NOTE: at start-up, the panel verifies the functioning of all LEDs.
- 2 Button to check the leisure battery (B2), the car battery (B1) and, with integrated twilight sensor, to set the intensity of the LED backlighting in a "night" situation (see also the "TWILIGHT" function).
- 3 Button to check the fresh water tanks.
- 4 12V button; it controls the lights and 12V sockets.
- 5 Waterpump button; it controls the pump relais.
- 6 Awning light button; the awning light switches automatically off when you start up the engine.
- 7 If this symbol blinks the car battery (B1) has run down.
- 8 If this symbol blinks the leisure battery (B2) has run down.
- 9 Voltmeter for the control of car and leisure battery voltage.
- 10 LED to signal 230V net on.
- 11 It indicates that the D+ functions are enabled.
- 12 It displays a system anomaly.
- 13 If this symbol blinks the fresh water tank is empty.
- 14 If this symbol blinks the waste water tank is full.
- 15 Fresh water tank level (Reserve level, 25%, 50%, 75%, 100%).
Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
Red LED blinking (ref. 7 on control panel) | Car battery (B1) discharged / low battery alarm | Car battery voltage is lower than 12V | The car battery alarm triggers automatically and symbol 7 starts blinking. | DIY Safe |
Red LED blinking (ref. 8 on control panel) | Leisure battery (B2) discharged / low battery alarm | The leisure battery's voltage has dropped below 11.5V | The leisure battery alarm triggers automatically and symbol 8 starts blinking. | DIY Safe |
LED flashing (ref. 1 on control panel) | Leisure battery running low - the minimum-voltage protection is about to engage | Leisure battery voltage dropping toward minimum threshold | An automatic device cuts all 12V circuits once the leisure battery reaches this 10V floor. Pressing the on/off button (ref. 1 on the control panel) restores everything for one more minute. The control panel itself shuts down completely below 9.5V, and everything reconnects automatically once the voltage climbs back above 13.5V. | DIY Safe |
Symbol ref. 13 blinks | Fresh water tank empty | Fresh water tank level is empty | Refill the fresh water tank. | DIY Safe |
Symbol ref. 14 blinks | Waste water tank full | Waste water tank has reached full level | Empty the waste water tank. | DIY Safe |
LED ref. 12 lit | System anomaly | System anomaly detected | Check system connections and components. | DIY Safe |
