Connections and Signals SGM PilotBox

Term. Signal Description

Act_Max_Current_0

Act_Max_Current_1

Control for output of the currently set charging current

This output issues the currently set charging current and is only

effective, if the output "Plugin_Detection" is enabled, i.e. a charg-

ing cable is plugged.

Binary 4-stage coding:

Act_Max_Current_0 Act_Max_Current_1 Power

inactive inactive 13 A

active inactive 20 A

inactive active 32 A

active active 63 A

11 Plugin_Detection Control for output of the charging cable detection

This output issues that the SGM PilotBox has detected the plug-

ging of a charging cable (proximity).

Interlock_1

Interlock_2

Connector locking control

This output serves for controlling the servo motor of the connector

locking.

Binary coding:

Interlock_1 Interlock_2 Action

inactive inactive none

inactive active unlocking

active inactive locking

18 Interlock_NO Normally open contact of the full-bridge motor driver for the con-

nector locking

Connected to GND when using the Mennekes connector.

19 Interlock_NC Normally closed contact of the full-bridge motor driver for the

connector locking

Connected to +12 V when using the Mennekes connector. In case

of an operating voltage below 13 V, this connection must be con-

nected to the operating voltage that the Mennekes actuator is

supplied directly from the operating voltage. In case of an operat-

ing voltage from 14 V, this connector must be left unconnected,

because the supply of the Mennekes actuator can be accom-

plished by an integrated regulator in the SGM PilotBox. In the volt-

age range 13-14 V, the connector can either be connected to the

operating voltage or not - the more reasonable variant should be

used here depending on the operating voltage tolerance.

recovery and following a restart of the device.
