intervolt DCC Pro Installation & Operation Manual page 42

In ignition control mode the charging process is controlled di erently because
the operator is e ectively directing the function of the device when they turn
the key on or o . Although the process is e ectively the same as it is under
voltage control mode, the sequence is di erent. There are also three basic
scenarios that dictate how the charger operates in this mode, details below.
Scenario 1: The ignition is on, the main battery voltage is above 12.0V and
the DCC Pro is in a normal charging cycle (boost, absorption or oat).
If solar power is actively available, the DCC Pro will implement primary solar
charging of the main and auxiliary batteries simultaneously. When the main
battery is fully charged (exceeds pre-determined maximum alternator voltage)
it will then be released and the DCC Pro will continue to charge the auxiliary
battery as long as required or until solar power is no longer available. In this
mode the LED Glow Ring will indicate aqua green continuously. In primary solar
mode the Remote Display is automatically enabled and the monitor will indicate
the auxiliary battery voltage, the charging power in Watts and display the text
PRM SOLAR.
Scenario 2: The ignition is on, the main battery is below 12.0V and the DCC
Pro is in standby mode.
In this situation, the DCC Pro is monitoring the main battery and waiting for an
increase in voltage (via the alternator when the engine is running or other
charging method) in order to initiate the charge cycle. If solar power is actively
available the Charging Device will charge the main battery until it reaches 12.5V
at which point it will also commence charging the auxiliary battery, e ectively
maintaining both batteries. Switching o the ignition will isolate the main
battery and silent solar will be initialised to take advantage of any available
power and charge the auxiliary battery (if required). The LED Glow Ring will
indicate aqua green intermittently. In silent solar mode the Remote Display is
disabled in order to conserve power however pressing the button will
OK
'awaken' the display and the monitor will indicate the auxiliary battery.
Scenario 3: The ignition is o and the DCC Pro is in standby mode.
With the ignition o , the main battery is isolated from the auxiliary battery and
it therefore cannot be utilised for normal charging. If solar power is actively
available, silent solar charging mode will be initiated and charge auxiliary
battery only. The LED Glow Ring will indicate aqua green intermittently. In silent
solar mode the Remote Display is disabled in order to conserve power however
pressing the button will 'awaken' the display and the monitor will indicate
OK
the auxiliary battery voltage, the charging power in Watts and display the text
SLT SOLAR.
