!MWARNING
When using Quick Hitch Type 2, the attachment can
become unexpectedly disengaged from the Quick
Hitch, when any of the following occurs:
Power failure to the Electronic Control Unit (ECU).
When the redundancy switch is engaged.
If an electrical component in the Quick Hitch system
should fail.
0178
The Quick hitch option allows the operator to quickly
change the attachment from within the cab.
There are two types that can be fitted and they operate in
different ways.
The system can be enabled and switched between types
via the SET + MODE (20 seconds) menu:
When the quick hitch switch is activated the EMS will
display the "Q/H DISCON?" message to verify the switch
operation and the switch status indicator will illuminate.
If the "ACK" switch on the EMS is not pressed within 5
seconds then the display reverts to normal and the switch
status indicator is extinguished.
The solenoid valve will only be energised/de-energised
once the "ACK" button on the EMS is activated. This is
included as a safety feature to prevent accidental
operation of the quick hitch system.
Once the "ACK" button is pressed the EMS displays the
message "Q/H DISCON" and the ECU1 o/p 23 (C-28) is
de-energised (type 1) or energised (type 2). The buzzer is
sounded while the quick hitch is disconnected.
To reconnect quick hitch press "ACK". The EMS will
display "Check Q/H" instructing the operator to visually
check the quick hitch attachment is securely connected.
Press "ACK" again to switch off buzzer.
