Caution:
Solid state outputs must only be used
to drive a solid state input device such as a safety
PLC and not a relay or solenoid. Solid state
outputs are monitored for safety and cannot be
put in parallel with any other device; doing so will
cause a fault in the SLT Series system.

Caution:
Pylons should be mounted in a manner
so that ony authorized personnel can change the
mounting or location.
Caution:
Additional guards may be required to
prevent the operator from standing between the
light curtain and the point of operation.
1) Locate pylons so the working zone is guarded
from reaching around, over, and under the SLT
Series system to the point of operation or hazard
zone. Mounting of pylons should be shock
mounted (see Safeguarding with Mechanical
Guards, Appendix A).
NOTE: For location of pylons in relation to the
hazard area, refer to Federal Register 1910.217
(c) (3) (iii) (e) and Table 0-10 (both are available
in Appendix A).
2) Determine the safety distance of the light curtain
from the point of operation using the ANSI
Standard B11.19-2003 (see Appendix A).
3) Refer to Dimensional Information for mechanical
layout of the pylons.
4) Refer to the Wiring Diagram and Wiring Color
sections for electrical connections.
5) Power is brought to both pylons 120V AC @
60Hz. The Ground Terminal must be connected
to a good ground connection, not conduit. A
bad ground may keep the light curtain from
going GREEN in an electrically noisy
environment.
6) Align the light curtain. If you have a keyswitch,
turn it to OFF or its lowest setting.
No communication between pylons:
Display
will show a 1 with flashing decimal points.
Communication but RED light:
Display shows
a 1 with no decimal points.
Green light:
Display shows a 0.
If a GREEN light cannot be achieved during
alignment,
see Diagnostics and
Troubleshooting).
7) Interface the light curtain standard relay output
contacts to the safety stop circuit.
8) Interface any remaining optional input or output
lines to their proper terminals (see Features
section).
9) Check and assure stop of machine when signal
of penetration is made anywhere in the curtain’s
field of view.
10) Mechanical guarding may also be required from
reaching around the light curtain to the point of
operation (see Table 0-10, Appendix A).
11) For installation assistance, please call
manufacturer’s service department at (800) 851-
2026.
12) Refer to the Light Curtain Test Procedure section
(Page AA-2) to ensure the light curt ain is
functioning properly.
