Use a dowel rod (or similar object) with a diameter equal

to the M.O.S. (Minimum Object Sensitivity) of the guard

you are testing. Move the rod through the field of the

curtain (i.e. top to bottom for vertically mounted cur-

tains). Repeat this test close to the Emitter pylon, close

to the Receiver pylon, in the middle between the py-

lons, and most importantly in front of the operator posi-

tion.

Make sure the curtain indicates a “Blocked” condition

(RED light) when the rod is in the field of the curtain.

Check and make sure the machine cannot move when

the curtain shows “Blocked”. If the machine can oper-

ate while the curtain shows a “Blocked” condition, then

re-examine your wiring.

NOTE: Always use both safety relays in your ST OP

circuit(s).

If the curtain does not show “Blocked” when the rod is

in the field: Check to make sure the rod is truly in the

curtain’s field, and re-check the curtain’s Minimum Ob-

ject Sensitity (including AutoBlank and Floating blank

options that change the M.O.S.).

Infrared light from the curtain may be reflecting around

the rod due to reflective material too close to the curtain’s

field. In this case, you will have to move the curt ain

pylons back away from the reflective material and re-

peat the test over again. The curtain’s power level can

also be reduced by the factory.
