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

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.
