DESCRIPTION

The Model 261XBXP(R) Alternating Relays use the
same solid-state latching and control circuit as all the other
261series models, the enclosure and the connecting base
being the major differences.

This version was designed to replace a long time and
widely used mechanical latching relay offered by another
manufacturer. The modern circuitry used in the Model
261XBXP(R) offers a vast improvement in reliability and
useful life over the mechanical type. The XBXP version of
the relay requires closing the control switch to begin
alternation, and the XBXPR version requires opening the
control switch to begin alternation.

Replacement of the original mechanical alternator with the
Model 261XBXP(R) requires the addition of one wire from
L1 to Pin 5 of the connector, in order to supply continuous
power to the solid-state circuit.

Either of these units is available in two voltage versions for
use with 24 VAC/DC or 120 VAC/DC.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

GENERAL SAFETY

POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 261XBXP(R).

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

INSTALLATION

Connect wiring to the socket as indicated in the
following examples.

The Model 261XBXP(R) Alternating Relay is extremely
versatile and can be used in many other configurations
besides those shown. Any type of switch (float,
pressure, etc.) can be used as the control switch;
however, it must be connected as shown (from L1 to the
control input) or the alternator will not function properly.

NOTE: When installing the Model 261XBXP(R) in areas
of high humidity or contamination, it is recommended
that the base area and all exposed metal parts of the
socket be coated liberally with a good quality silicone
grease, such as Dow Corning DC-4 or DC-4X. Insert
the unit into the socket and wipe off excess grease
around the base. This will prevent the entrance of
moisture and other contaminants into the base and
socket area.
