Combo1 Inlet
The VC-EVCC interprets the measured voltage (PlugPresent_Voltage) to detect if a cable
is connected (PlugPresent_Status).
Caution
If the value of the internal resistor between PP and PE is configured to 2,7 kOhm, the
VC-EVCC will consider a Combo1 inlet connected and calculate the plug present
voltage accordingly.
The Combo1 plug has a built-in switch. If the plug is connected the VC-EVCC determines
the status of the switch from the measured voltage. It is made available on the CAN Signal
S3Switch_Status to be communicated on CAN1.

Note
The values of the Plug Present Voltage are no real measured values. They are just the
mean of the defined voltage range. A real calculation of the voltage value in software is
too complex.
Combo1 does not support the PlugPresent Resistance, therefore the signal
PlugPresent_Resistance is set to SNA.
If the CAN Signal PlugPresent_SelfDiagnosticStatus has any fault value, the signal
S3Switch_Status is set to Error.
