Crush Guard - Installation - Genie Z-40/23N Machine Connections
This Tech Doc shows how to complete the connections to the machine
Installation steps:
1. Remove the 4 bolts that secure
the lid to the operator control
box.
2. Drill a 20 mm hole in the location
marked earlier for the M23
connector.
3. Insert the supplied cable wire
harness up through the exposed
hole (making sure that the M23
connector remains on the outside
of the operator control box).
4. Using a 24mm open ended
spanner secure the M23
connector to the control panel
using the supplied metal lock
nut.
5. Make sure that the nut is
done up tight to avoid the
connector rotating.
6. On the emergency stop switch, locate the 24V power supply
output signal.
7. Remove the 24V power supply
from the emergency stop
terminal and replace with the
fork terminal on the pink / blue
wire from the Crush Guard wire
harness.
8. Cut off the fork terminal from
the 24V power supply wire that
was removed from the
emergency stop switch and
crimp join the white wire from
the Crush Guard wire harness. See Note 1.
9. Locate the 24V deadman signal (which is 24V when the deadman
foot pedal is pressed).
This can
typically be found on the drive
speed switch or on other
switches where the function is
enabled when the deadman foot
pedal is pressed.
10. Attach the ring lug on the yellow
wire from the Crush Guard wire
harness to the 24V deadman
signal. See Note 1.
11. Locate the connector to the
deadman foot switch and
determine which wire contains
the deadman foot switch common
signal.
12. Cut the deadman foot switch
common wire and join the green
and brown wires from the Crush
Guard wire harness onto each
end of the wire.
See Note 1. See Note 2.
13. Attach the black wire with the
female spade terminal from the
Crush Guard wire harness to the
ground point connector block
inside the operator control box (as shown in the image below). See Note 1.
14. Secure the Crush Guard wire
harness to the existing wires
using cable ties.
Note 1. The control box electronics may be different from the picture shown.
Note 2. The direction of the wire colours is not important.
