Commissioning and operation

Disabling emergency operation
Emergency operation is always terminated automatically when the engine is switched off;
the ignition must be switched off for at least 3 seconds.
After switching on again, normal control lever operation is enabled first, i.e. the emerg-
ency operation system must be reactivated if required.
Fault messages
Two LEDs on the Em-C operating unit (green LED “Power On” and red LED “Failure”)
enable the distinction of various failure states:
Green LED off and red LED off
Ignition switched off or no supply voltage
(emergency operation not possible)
Green LED on, red LED flashing without any other operating key also flashing
Failure of the internal engine speed signal
(function still possible with delayed shift times)
Green LED on, red LED flashing together with the forwards key
Fault following gear shift in forwards direction
(this travel direction can no longer be activated)
Green LED on, red LED flashing together with the reverse key
Fault following gear shift in reverse direction
(this travel direction can no longer be activated)
Green LED and red LED continuously on
System failure or no communication between Em-C and Em-R.
(emergency operation not possible)
Em-R is the receiver component in the terminal box.
Fault states that are indicated by flashing on the Em-C operating unit must be acknowl-
edged using the (N) key after the fault has been rectified. Until this acknowledgement,
the fault message continues to flash.
