PROGRAMMABLE OUTPUT SELECTION — The programmable
N.O./N.C. proximity switch is factory preset in either the normally
open or normally closed output mode.
To change the switch output mode use the following instructions.
1. Remove the lower legend plate on the front of the switch.
2. A line on the recessed rocker indicates the output mode of
the switch.
3. To change the output, depress the recessed rocker of the
switch with a pointed tool.
Note: Do not use a tool whose point could break and jam the
switch.
4. Replace the lower legend plate.
To return the output mode to its original setting, simply reverse
the above procedure. The OUTPUT LED will be ON when the
switch output is conducting.
HARD WIRED CONTACTS — When hard wired contacts are
connected in parallel with the Bulletin 802PR, a surge suppressor
MUST BE connected in parallel with the load. Surge suppression is
not required when hard wired contacts are connected in series
with the load. For recommended surge suppressors for various
devices, refer to publication 802PR-2.1 product data.
NOTE: Hard wired contacts that are operating in series or parallel
with the Bulletin 802PR Type LA or Type XA will cause a delay of
approximately 200 ms. This power-up delay will reduce the
maximum number of operations per minute and may result in a
momentary de-energization of the load.
CONDUIT COUPLED SWITCHES — Threaded conduit opening
bases are suitable for use with flexible conduit. Conduit coupler
bases are suitable for use with both flexible conduit and rigid
conduit. Both bases connect to 1/2 in.-14 NPT threaded conduit.
Switches with a “S6” suffix in their catalog number are suitable
for connection to ISO 20-1.5 threaded conduit.
PREWIRED CABLE SWITCHES — These switches include a
prewired cable for connection directly into a junction box. The
cable is a two conductor, oil resistant thermoplastic (STO).
PREWIRED RECEPTACLE SWITCHES — These switches include
a prewired receptacle suitable for use with the connector-cable
assemblies listed in the table below. Figure 6 indicates which two
pins of the receptacle are wired internally to terminals 1 and 2.
The third pin is not used.

TROUBLESHOOTING GUIDE — The following guide provides basic troubleshooting information for installation and use of the proximity
switch. If a problem occurs, attempt to determine the POSSIBLE CAUSE as listed. Apply the suggested SOLUTION.
NOTE: The switch may continue to operate even if the LED (will not light) is damaged.
Programmable N.O./N.C. switches have two LEDs. The POWER LED will be ON when power is applied.
N/A — Not Applicable.
MOUNTING DIMENSIONS — Dimensions shown in mm (inches).
