9. Electrohydraulic remote control (optional extra)
For more details please see also "Electrohydraulic remote control" Chapter 8618 Index A and Index E
Reason / use:
Some implements - e.g. sugar beet topper-lifter - have their own position sensor (component
designation not available). This mode is sometimes referred to as "momentary-contact control".
Connection / required adaptation:
Relevant circuit diagram: "Electrohydraulic control"
External sensor is connected to white socket X015 at rear of tractor. This works from EPC box A005
with same 9.5 V supply voltage at same pin 39 and with same earth at same pin 20 as tractor sensor
B030. Specific contact - pin 48 - is available for signal from external sensor.
EPC box itself detects any connected external sensor and then continues to work with this signal, i.e.
no further action is necessary.
Diagnostics:
Because it has its own contact, external sensor can also be checked by diagnostics system in event of
electrical signal faults (fault code 8.3.26).
Faults in the earth power supply (common terminal; socket X015 not available = sensor not connected)
are not self-testing and may be confusing.
