|---|---|---|---|
PCB Over Heat (Flash) | Unit fails to operate – seems completely dead – Red Light flashing on ECB Possible Cause: Over heating | Remove isolation key and leave 20 minutes to see if the thermal fuse will reset itself, RED LIGHT WILL STOP FLASHING and the ECB should not feel hot. | DIY Safe |
Operational Fault | Unit fails to operate or moves intermittently – Green light flashing on ECB Possible Cause: Caravan battery low | Check voltage of battery (see battery voltages chart Section 5 Paragraph 5.4). Charge or renew caravan battery. | DIY Safe |
N/A | Unit fails to operate | Reset the ECB by turning off the isolation switch and removing the key for at least 20 seconds and then turning on again. The green light on the ECB should be illuminated. | DIY Safe |
N/A | Unit fails to operate – seems completely dead | Check that the green light is illuminated on the electronics, if not check that the in-line fuse is not broken and 12volts DC is getting to the ECB. | DIY Safe |
N/A | Unit fails to operate or operates intermittently | Check the battery voltage of the handset is correct at 9.5 volts. If the 2 rows of Red LED's flash, then this is a sign the handset battery is low | DIY Safe |

N/A | Caravan fails to move or moves intermittently Possible Cause: Caravan battery low | With the rollers engaged move the caravan and check the voltage drop on the caravan battery meter. If this drops below 12 volts, it is advisable to have the battery tested by an accredited supplier, then as necessary charge or renew caravan battery. | DIY Check / Tech Fallback |
