The G relay terminals do not need a catch diode across the relay coil to protect from the flyback voltage This protection is built into the G terminal Intermediate Relay 4e It can be difficult to determine what current is required to operate the remote start The best way to do this is to measure it Short the remote start terminals with a multimeter on its current range Generator and measure the current R t The manufacturer s manual should contain this SIMOIS information but often does not Start Unit The generator control provided by the Dingo is G relay switches a larger relay simple a contact closure is provided when the generator should run and the contacts open when the generator should be stopped It does not handle the issues associated with starting such as fuel and what to do if the generator does not start This should be handled by the remote start unit Fig 2C Generator start wiring with an intermediate relay Dingo 2020 Reference Manual Rev 1 5 4 02 13 3 0 LOAD Menu LOAD The LOAD screen gives real time total load current in Amps This total is the sum of the current flowing through the load terminal LINT and any external load current This may be current from an external switchblock or an external current measured using a current shunt and a DSA LINT From the LOAD screen a long push displays LINT Load Internal This is the real time

GSET if using the G relay to switch the changeover relay BSET I B input used for 2nd battery control The B sense input is wired to the positive terminal of the second battery and allows voltage monitoring of the second battery voltage This allows the regulator to perform basic single stage regulation of the second battery by switching the relay on or off to connect disconnect the charge source second regulator is NOT required The changeover relay will need to meet the following minimum specifications Correct coil voltage to match the system voltage ie able to handle the maximum battery voltage Output contacts rated for DC current Output contacts rated to handle the maximum current that the connected panels can output Note It is suggested that customers leave some panels permanently connected to the regulator 501 input Ist solar and switch all the other panels 2nd solar across with the relay This leaves a regulated maintenance charge available for the Rev 1 5 4 02 13 Dingo 2020 Reference Manual primary battery and can minimise the amount of cause some ringing on turn off Keep wiring as switching required by the relay which switches over short as possible and panel cable pairs together each time the primary battery bank voltage falls cable tie On long wiring runs at higher voltages below HYST The maximum relay switching some damping may be necessary an
