- Disable RK4 by disconnecting lead 40 and using a jumper lead to connect leads 33
and 39 together (lower operating panel) for the duration of the test.
- Retract the boom and extend it again, measuring the extending part of the telescope
- The length should be 3600 ± 30 mm (141,7 ± 1,2 inches)
- If the extending part is too long, adjust the limit switches and secure them by
applying a seal.
- Retract the boom and reset the relay R25 from the button (fig.3)
-
WARNING! Do not forget to make the limit switch RK4 functional by reconnecting
lead 40 to the terminal block.
Setting the overload devices Rk4 and Rk5 (fig. 2, 4)
When servicing, always test both overload limit switches
- Load the platform with for example 80 kg (175 lbs)
- Move the boom into horizontal position
Setting procedure, alternative 1.
- Set the actuating point of RK4 far enough to ensure that RK5 is actuated before RK4
- Extend the boom, and measure one part of it (stroke)
- The stroke should be 3600 ± 30 mm (141,7 ± 1,2 inches)
- Tighten the adjustment locking nut and test the actual values once more (if Rk5 is actuated for
more than 4 seconds, relay R25 must be reset)
- RK4 should be set to actuate before RK5
- Extend the boom and measure the stroke
- The length should be 2900 + 30 mm (114 ± 1,2 inches)
- Tighten the adjusting screw and test the actual values once more
- Attach a securing wire onto the adjusting screw in a way that excludes every possibility to unscrew
the adjusting screw, and attach a seal to the wire
- Fasten the protective panel
Elsewhere in this manual another alternative way of securing the RK5 is described, for the
case that the securing wire is already attached (regular service, item 10)
