OPERATION OF WORK EQUIPMENT AND TRAVEL AUTOMATIC LOCK SYSTEM
When an oil pressure switch or a sensor detects pressure high-
er than specified pressure (D) or an attachment drive signal is
input within certain time (C) after the lock lever is unlocked (A),
this function judges that the operation is abnormal and the
pump controller outputs the lock lever automatic lock relay
drive signal to shut off the current to PPC lock solenoid to lock
the machine (B).
A: PPC lock lever is canceled
B: Lock lever automatic lock operates
C: Within 0.4 sec
D: 500 kPa
E: 0.1 sec.
REMARK
When the hydraulic oil temperature is low or high-viscosity hydraulic oil is used, the pressure does not increase
within time (C), and the lock lever automatic lock control may not operate.
Control when lock lever automatic lock cancel switch is “ON”
If PPC solenoid valve does not operate and the operator can-
not work because of abnormality in the controller, the operator
can operate the machine by operating lock lever automatic lock
cancel switch (1).
At this time, the lock lever automatic lock control function does
not work.
a: Emergency (when abnormal)
b: Normal (when normal)
REMARK
Lock lever automatic lock cancel switch (1) is an alternate type
switch. If it is set to “Emergency” position (a) while PPC lock
lever is in the free state, the lock lever automatic lock cancel pi-
lot lamp lights up on the display.
The following failure codes are recorded when this switch is “ON”.
