Signals

Description

The Catalog Series 51(*)-E1 and 51(*)-G1 Adaptabeacon signals
are dc operated, weatherproof, combination flashing lights with
horns. They feature optically designed polycarbonate lenses.
These signals are suitable for installation on a vehicle, or perma­nent outdoor or indoor installation. Their base allows direct sur­face mounting, mounting on 1/2" (13 mm) NPT conduit, or mount­ing on a 4" (102 mm) octagon box. A hardware kit is included
with the signals for direct surface mounting applications.

51(*)-E1 12V DC 1.0 Amps

51(*)-G1 24V DC 1.0 Amps

*The letter (A - amber, B - blue, C - clear, G - green, M ­magenta or R - red) in this position signifies the color the
supplied lens.

Replacement lamps, horns, flasher modules and lenses are avail­able for the signals. Refer to the table at the end of these instruc­tions for details.

PLC Compatibility

The electrical input load requirements for PLC compatible sig­naling devices are listed in Table 1. Signaling devices may be
directly connected to output cards that meet these input load re­quirements.

Installation

1. Remove the base from the signal using the following
procedure:

See Figure 1. Remove the screw in the clamp ring, remove
the ring, and lift the lens/lamp assembly off the base. Now,
install the base as described in Step 2.

2. The signal can be direct surface mounted, mounted on 1/2"
(13 mm) NPT conduit, or mounted on a 4" (102 mm) octagon
box. Install the signal base using one of the following
mounting procedures.

Direct Surface Mounting

a. Remove the two knockouts for mounting screws from

the signal base bottom. (See Figure 1 for the location of
knockouts.)

b. Refer to Figure 2 before continuing the mounting

procedure. Then place the gasket provided in the
hardware kit on the mounting surface, and mark the
center of the three holes in the gasket on the surface.
Remove the gasket and drill a 3/8" (9.5 mm) hole at
each of the marked positions.

c. Install the two rubber expansion plugs provided in the

hardware kit into the two outer holes in the mounting
surface as indicated in Figure 2.

d. Route the field wiring from the required power source

for the signal (refer to its label for the voltage rating)
through the center holes in the mounting surface, gasket
and base.

e. Align the holes in the gasket with the holes in the base.

Insert the two screws with lockwashers provided in the
hardware kit through the mounting holes inside the base
and align the screws with the rubber expansion plugs as
shown in Figure 2. Press the base firmly against the
mounting surface and tighten the screws. Now proceed
to step 3 for wiring connections.

Install in accordance with the latest edition of the National Elec­trical Code and local codes.

WARNINGS

To prevent electrical shock, ensure that power is
disconnected before installing the signal.

To prevent leakage and potential electrical shock,
use care when disassembling the signal to prevent
tearing of the permanently affixed gaskets provided
for weatherproofing.

WARNING

To prevent leakage and a potential shock hazard,
when mounting outdoors the signal must be
installed with the lens or dome facing directly up.

a. Route the field wiring from the required power source

for the signal (refer to its label for the voltage rating)
through a 1/2" (13 mm) NPT conduit (not supplied) and
through the center hole in the signal base.

b. Install the base on the conduit. Now proceed to Step 3

for wiring connections.

Installation Only)

Lamp Replacement

Refer to the Replacement Parts table below for the required type
of lamp. After disconnecting power, replace the lamp using the
following procedure:

a. Remove the two knockouts for mounting screws from

the bottom of the signal base.

b. Route the field wiring from the required power source

for the signal (refer to its label for the voltage rating)
through the center hole in the base.

c. Fasten the base to the octagon box (not supplied) by

installing the screws supplied with the box through the
holes in the base. Now proceed to Step 3 for wiring
connections.

3. Using wire nuts (not supplied), connect the signal's red wire
to the positive (+) power source lead and connect the black
wire lead to the negative (-) power source wire. Then neatly
place the connected wires inside the base and reassemble the
signal on the base.

4. Turn on power and verify that the signal operates properly.

Maintenance

WARNINGS

To prevent electrical shock, ensure that power is
disconnected before installing the signal.

To prevent leakage and potential electrical shock,
use care when disassembling the signal to prevent
tearing of the permanently affixed gaskets provided
for weatherproofing.

See Figure 1. Remove the three screws from the top of the skirt
and lift off the skirt and lens. Remove the old lamp. Insert the
new lamp.

Horn Replacement

Refer to the Replacement Parts table below for the required horn.
After disconnecting power, remove the old horn and attach the
new one. Reattach the horn module wiring to the flasher module
wiring.

Cleaning

CAUTION

To prevent damage to the lens, do not use abrasive
materials or cleaners.

The signal lens should be periodically cleaned to maintain opti­mum light visibility. It may be cleaned with a soft cloth or sponge
using mild detergent. Dry the lens completely before replacing.

Troubleshooting

If the lamp fails to operate, check that power is on. If power is
on, either the lamp or the solid state flasher module should be
replaced. Replace the lamp first as directed in the Lamp Re­placement section above. If the replacement lamps also fails to
operate, the flasher module must be replaced. Refer to the Re­placement Parts table below for the required flasher. Instructions
for replacing the flasher are provided with the flasher.

NOTE: If both the lamp and horn fail to operate, the flasher

module must be replaced.

Replacement Parts

Replacement lamps, horns and lenses for the 51 series signals may be obtained from your Edwards distributor.
