knock-out holes in the base. Proceed to step 3 for wiring
connections.
Mounting on 1/2" (13 mm) NPT Conduit
WARNING
To prevent leakage and a potential electrical hazard,
when mounting outdoors the signals must be
installed with the lens or dome facing directly up.
a.
Route the field wiring from the power source through the
1/2" (13 mm) NPT conduit (not supplied) and through
the conduit entrance hole in the signal base.
b.
Install the base on the conduit. Proceed to step 3 for
wiring connections.
3.
Using wire nuts (not supplied) connect the field wiring to the
signal wire leads. Polarity is not important. Connect the
green ground wire leads using wire nuts (not supplied). 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
WARNING
To prevent electrical shock, disconnect power and
allow five (5) minutes for stored energy to dissipate
before disassembling the signal.
To prevent leakage and a potential electrical hazard,
use care when disassembling the signal to prevent
tearing of the weatherproof gaskets. If a
component resists removal due to adhesion to a
gasket,
do not force apart by hand; carefully
separate the components by prying them apart with
a thin blade screwdriver.
CAUTION
To prevent damage to the lens and/or dome,
do not
use abrasive materials or cleaners.
CAUTIONS
To prevent damage to the strobe tube, lift the lens
straight up and off of the signal.
To prevent damage to the strobe tube, handle the
strobe only by its base.
Cleaning
Periodically clean the signal lens and dome (as applicable) to
maintain optimum light visibility. These items may be cleaned
with a soft cloth or sponge using water or a mild detergent solu-
tion. Ensure that the lens and dome are completely dry before
replacing.
Strobe Tube Replacement
Refer to Table 1 for the required strobe tube.
1.
After disconnecting the power and waiting five minutes for
stored energy to dissipate, disassemble as follows:
a.
90 Series:
Refer to Figure 1. Remove the screw in the
clamp ring, remove the ring and lift off the dome. Loosen
the three screws in the base of the lens, turn the lens
clockwise and lift it straight up and off of the strobe
tube support late, being careful not to dmaage the strobe
tube. Proceed to step 2.
b.
92 Series:
Refer to Figures 4 and 5. Remove the screw in
the clamp ring and remove the ring.
For the 92-N5 series, remove the three screws holding
the lens retaining ring and lens to the strobe tube support
plate. Being careful not to tear the gasket which is
permanently affixed to the lens, lift the lens straight up
and off the plate.
For the 92-R5 and 92-S1 series, lift the lens off of the
signal base, being careful not to tear the gaskets
permanently affixed to the lens.
Proceed to step 2.
c.
95 Series:
Refer to Figure 6. Remove the three screws
holding the skirt and lens to the strobe tube support plate.
Lift the skirt up over the lens and off the signal. Being
careful not to tear the gasket which is permanently affixed
to the lens, lift the lens straight up and off the plate.
Proceed to step 2.
2.
Grasp the base of the strobe tube and pull firmly, or carefully
pry between the strobe tube base and the socket, to remove
the tube from the socket. Install the new strobe tube by
aligning the key on the strobe tube base with the slot in the
socket and then pressing the strobe tube base onto the socket.
Reassemble the signal.
3.
Turn on the power and verify that the strobe operates.
