when using, does it flash battery, if does try charging the van battery to give it a full charge, and if it carrys on flashing then check alternator if kicking out enough as battery might be knackered
Some good advice from ORI.
Your control has a battery protection system. The unit will flash BAT if voltage of less than 11.5V is detected the pump will continue to work no problem.
If the control detects 11V or less the control will shut the pump down. so please see the below advice.
1. Are the connections to the controller from the battery as short as possible?
This is because the longer the wire the greater the volt drop. For instance you could measure 12.5V at the battery but only measure 11.5V at the controller when the pump is running. This is because of the losses in the wiring from the battery to the controller.
Remember that:
Below 11.5V the controller flashes 'BAT' warning that the battery is low.
Below 11.0V the controller shuts down to protect the battery. This is because the battery manufacturers recommend that a battery is not run below 11.0V, because you risk permanent damage to your battery if you run your pump below this point.
2. The connections to the controller need to be good. We recommend you keep the connectors supplied already connected to the unit, which have been tested. If you change these you risk making a poor connection. This may mean a greater volt drop and result in the same problem as outlined about when the wires are too long.
It is also worth checking the battery is fully charged
Please let me know how you get on.
