Installation Instructions for Machlight TM
Machine Status Indicator
Description
The Edwards Machlight TM Machine Status Indicator is a multi-
device that contains three light modules (red, amber, and green) in
a single tower.
The unit is UL and cUL listed for Industrial Control indoor appli-
cations (UL 508).
The unit's optically designed lenses are vertically fluted and eas-
ily removed in order to facilitate relamping or to resequence the
stack colors.
The unit is available in either a surface or pole mount version in
24VAC/DC or 120VAC. Each version is available as a steady or
flashing model. All models have flying leads for connecting field
wiring. See Table 1 for specifications and Table 2 for product
descriptions.
PLC Compatibility
The electrical input characteristics for PLC compatible signals are
listed in Table 3. Signals with these characteristics may be di-
rectly connected to PLC output cards that do not exceed these
input characteristics.
Installation
Installation must be in accordance with the latest edition of the
National Electrical Code and other governing standards and codes
for standard installation.
1. For direct surface mount versions perform the following:
a. Using Figure 1 as a guide, mark the three mounting holes
and the center wiring clearance hole on the mounting
surface.
b. Drill the three mounting holes and the the wiring clearance
hole in the mounting surface.
WARNINGS
To prevent electrical shock, do not connect power
until instructed to do so.
To prevent abrasion of wiring insulation, ensure
that wire clearance hole is adequately protected.
c. Feed the unit's wiring through the wiring clearance hole
and, using the screws and nuts supplied, attach the unit

Reattach the signal to the mounting bracket using the
removed mounting nut and washer.
c. To mount the unit to the top of a machine, drill a 1/2"
(13mm) hole in the mouting surface. Remove the bottom
mounting nut, washer and mounting bracket and feed the
unit's wiring through the mounting hole. Fasten the pole
to the surface using the removed mounting nut and washer.
3. Using wiring nuts connect field wiring to the unit as follows.
a. Connect the black lead marked with the red tag to the
appropriate field wire positive DC or AC hot lead.
b. Connect the black lead marked with the orange tag to the
appropriate field wire positive DC or AC hot lead.
c. Connect the black lead marked with the green tag to the
appropriate field wire positive DC or AC hot lead.
d. Connect the white lead to the field negative DC or AC
neutral lead.
e. Connect the unit's green with yellow stripe ground lead
