HAZARDOUS LOCATION SWITCHES — Switches for hazardous locations meet Division 2; Class I Groups A, B, C, & D; Class II, Groups F & G; and, Class III requirements. For additional information refer to Publication GI-2.8 — A Summary of National Electrical Code Requirements for Hazardous Locations.

NOTE: To guard against the load remaining energized when the switch is in an open condition, the minimum load release current must be greater than the maximum leakage current of the proximity switch.

GROUNDING — The Bulletin 802PR does not require a ground connection. The load side of the110/120V AC source can be grounded as indicated in the connection diagram.

SHORT CIRCUIT PROTECTION — A fuse is recommended in the circuit to provide short circuit protection for the switch. Use a fast acting Type KAW10 or KAX10 fuse.

SERIES CONNECTED SWITCHES — Normally Open Fixed Output — Do not connect two or more

of the switches in series. Erratic operation may result.

Programmable Normally Open/Normally Closed Output

— Two switches can be connected in series with a load. For proper operation, the operating load voltage must be less than or equal to the minimum supply voltage less the sum of the onstate voltage drops across the series connected proximity switches. The load will be energized when the OUTPUT LEDs of both proximity switches are ON.

WIRING — Connect the proximity switch and load as shown in

SPACING BETWEEN SWITCHES — When installing switches side-by-side or face-to -face, the minimum spacings in Figure 3 should be maintained.

EFFECTS OF NEARBY METAL SURFACES ON SENSING DISTANCES — The sensing distance will increase if the

proximity switch is installed so that metal is adjacent to the

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 CO UPLED 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.
