SECTION 3—INSTALLATION OF COMPONENTS
WIRING
(continued)
PALM BUTTON ASSEMBLY
(See page 25)
These are normally wired as an assembly with the blue wires routed from the control box to the nearest palm button and then the others, as required.
Wires between the two run/inch buttons are not connected back to the control box. If Touchdown!™ (proximity) palm buttons are furnished, please
refer to the enclosed Installation Manual No. KSL-071 and the connection print provided.
If the palm button assembly is not bolted directly to the machine frame, then a separate green ground wire should be run from the control box to all
palm buttons. Attach one end of the wire to each mounting box by a lug under one of the mounting bolts and the other end of the wire to the GND
terminal in the control box to assure proper grounding.
These operator controls should be mounted in a convenient location, keeping ergonomics in mind. To comply with the OSHA regulation for two-hand
control, the run/inch buttons must be located according to the minimum safety distance requirements of each individual machine as defined by OSHA
1910.217 (c)(3)(vii) (see page 27 of this manual). A stop-time measurement is necessary for checking stopping time before installation begins to
determine the safety distance of the two-hand control palm buttons furnished with the control. After installation, the stopping time can be obtained
from the built-in stop-time measurement system or a portable stop-time measurement unit.
FOOT SWITCH
(See page 31)
Run
1
⁄
2
” nominal flexible conduit or cord from the foot switch to the control box. Connect the contacts according to the control drawing schematic.
In general, connect one wire from one side of the normally open and normally closed contacts to a COM terminal, and a wire from the other side of
each contact to the appropriate control module input terminal. If multiple foot switches are used, the COM connection may be split up. Refer to the
multiple operator drawing for wiring details. Be sure to connect the ground in the foot switch to the GND terminal in the control box with a green wire.
SUPERVISORY CONTROL STATION
(See page 32)
Mount the station in a convenient location where it is easily accessible, or as part of a palm button assembly (see page 26). See wiring schematic LLD-
1501 for proper wiring of the supervisory control station.
MULTIPLE OPERATOR JUNCTION BOX
(See page 32)
Run
3
⁄
4
” nominal conduit from the junction box to the control box. Pull the cable through the conduit and connect it to the appropriate terminals
according to the junction box drawing. Connect each supervisory control station to the multiple operator junction box with the cable.
Note: The junction box should be located for easy access to the fault reset button in case a fault should occur.
BAR/RUN STATION
(See page 32)
Run
1
⁄
2
” nominal conduit from the bar/run station to the control box. Pull red wires through the conduit according to the drawing.
Note: The bar/run station should be located for easy access to the bar push button while barring the press.
PRESS GROUND
The machine frame must always be firmly connected to ground in order to ensure that the control potential will never exceed 120 V above
ground. Run a green grounding wire from the control box to some convenient location directly on the machine frame. Connect one end
solidly to the frame using a mounting bolt or other convenient means of attachment. Scrape any paint, rust, etc., from the area to ensure
an adequate ground connection. Connect the other end to the GND terminal in the control box.
Note: All exposed metal components, which may be touched by personnel during normal operation or adjustment, must be firmly grounded to the
machine frame. The disconnect switch and motor starter should also be grounded if they are mounted separately.
