LIMIT-SWITCHES
RK3: LIMIT SWITCH FOR THE BOOM SUPPORT
Prevents the operation of the outriggers and the driving device if the boom does not rest on
the support in the transport position. Controls the relay K30.
RK4: SAFETY LIMIT SWITCH FOR THE ADJUSTED OPERATING RANGE
The operation of the limit switch stops the "boom down" movement and the "telescope out"
movement.
RK5: BACKUP LIMIT SWITCH FOR THE SAFETY LIMIT SWITCH RK4.
Trips after the preset delay (2,4 seconds) the safety relay SR3 which controls the sound
signal AM2 and switches off the control voltage to the limit switch RK4.
RK7: SAFETY LIMIT SWITCH FOR THE TELESCOPE CHAIN.
Operation of the safety limit switch stops the electric motor. The limit switch switches off
the control voltage to the contactor K1 after which only the emergency descent unit will
operate.
RK8: "TELESCOPE IN THE INNER POSITION" SAFETY LIMIT SWITCH
The limits switch closes as the telescope movement is completely retracted.
If the RK4 or RK5 has failed the boom cannot be lowered until the telescope movement has
been completely retracted and the tips of the limit switch RK8 have closed.
RK9: INDUCTIVE LIMIT SWITCH
Limits turning of the platform to the left by disconnecting the control voltage circuit for the
relay K51.
RK10: INDUCTIVE LIMIT SWITCH
Limits turning of the platform to the right by disconnecting the control voltage circuit for the
relay K52.
RK11 - RK14 : LIMIT SWITCHES ON THE OUTRIGGERS
The limit switch closes as soon as sufficent force is exerted on the outrigger.
Prevents the operation of the boom unless the outriggers are not firmly supported on the
ground and all limit switches are not closed.
