It is recommended always to have a charged battery
available, to charge another battery in the charger, and
to change the batteries about every eight hours or
before each new working shift.
Disturbances
If, during the operation, the machine does not respond
to control commands:
•
change the transmit frequency. If this is unsuc-
cessful:
•
push the EMERGENCY SHUT-OFF button
•
change your location
•
put the control unit into operation
•
check LEDs on transmitter:
2 + 4 = off
3 = permanently lit or flashing
If the control unit cannot be put into operation, see
section 15
Frequency Change
Changing the transmit frequency with selector switch 6
makes sense only if another transmitter with the same
frequency is being operated in the vicinity, or if
irregularities in the transmission are suspected.
During a change of the frequency, the operation will be
interrupted for about 3 seconds, as the EMERGENCY
SHUT-OFF circuit of the receiver will be interrupted.
12. Emergency
S
hut-Off
The control unit is equipped with 2 separate
EMERGENCY SHUT-OFF modules.
If a fault is detected by at least one of the modules, the
machine control system passes over to the
EMERGENCY SHUT-OFF state.
The EMERGENCY SHUT-OFF valve in the hydraulic
system opens.
The hydraulic system is now working in the
pressureless circulation mode and the main functions
are stopped.
The EMERGENCY SHUT-OFF condition is triggered,
for instance, by pressing an EMERGENCY SHUT-
OFF button or by low battery voltage.
In addition, the receiver carries out constant checks:
•
of the transmitted data messages
•
whether the control commands are executed
(double reading)
•
the electric components of the receiver and
output circuits.
If faults are detected, the unit passes over to
EMERGENCY SHUT-OFF.
Cf. section 15.
The unit can be restarted only after the fault has
been rectified.
Cf. section 10.
