In our V2.1 and above controllers, the battery and charging circuit has been redesigned to prevent the controller battery from cycling down past the level that prevents charging by the solar panel.
This can happen when the controller is left on with no ability to charge. This redesigned circuit will shut down the controller before the battery goes into an unrecoverable state.
In previous edition controllers, this would require the controllers by sent back to Modusense for repair.
Jump Start Cable
The Jump Start Cable is a small cable with one M8 connector at each end.
To use the Jump Start cable, we will disconnect the solar panel cable from the bottom of the controller and then use the Jump Start cable to restart the controller.
The same Jump Start cable can be used any time the battery level goes below that required to charge itself.
Laying down the controller
Take your controller and place it on a flat surface carefully with the solar panel facing downwards and the writing on the keypad the correct way up.
Disconnecting the solar panel cable
Detach the solar panel cable from the main controller unit.
The M8 connector from the Solar panel is attached to the ModuSense Controller Gateway with a water-tight fitting that must be unscrewed (anti-clockwise) before removing.
Never use tools to turn this connector, only your finger and thumb, the connector can spin internally if over-tightened and might damage the electronics or even break the connector.
Adding the Jump start cable
Grab the jump start cable and make sure you are holding the cable with the label words the right way up.
Connect the end underneath the label to the solar panel cable.
Connect the end above the label with the 90 degree bend to the main controller unit.
Taking the unit outside and powering up the unit
Once you have connected the jump start cable, take the unit outside.
Press the Power button.
NB: If the unit is turned on inside and remains inside, the controller will discharge the battery beyond the point where it can be charged at all.
Pressing the Test button button should show a solid Green LED to indicate the unit is on, or a flashing green button to indicate that the unit is charging.
Depending on the under voltage level of the battery, the flashing LED light might take a little while to flash as the battery level is still under the threshold to flash the LED. As long as the unit is outside in the sun, it should be charging.
Removing the Jump Start cable
Once the battery level has sufficiently charged, the jump start cable should be removed.
The easiest way to check the battery level is to check the battery panel on the Dashboard.
In the battery panel, you will find the various battery levels of the controller and any of the devices that are connected to it.
The first graph will display the name of the controller and the battery level. Once you've reached 50% or more, you should remove the Jump Start cable.
Disconnect the cable from the main unit and then disconnect the Jump start cable from the solar panel cable.
Reconnect the solar panel cable to the main controller unit by pushing the M8 connector into the main until and screwing clockwise with your fingers until you have a tight fit. Do not overtighten as this could break the connector.
