Edwards Signaling 57PLEDM Series - Manual (Page 2)

2 / 4 P/N 3101961-EN • REV 02 • ISS 24JUN14
To wire the beacon for 24 VAC/VDC:
1. Using wire nuts (not supplied), connect the field wiring to
the beacon wiring.
2. Connections depend on the voltage supply. Choose the
connections that match your power supply:
24 VAC: Connect the beacon’s black lead to hot, the red
lead to neutral, and the green lead to ground.
24 VDC: Connect the beacon’s red lead to positive (+),
and the black lead to negative (−).
Selecting the flash or rotation pattern
The beacon can be configured with one of 16 user-selectable
flash or rotation patterns using a push button (membrane
switch). The push button is located in the center of the
Edwards “shield logo” on the base of the beacon (Figure 1).
To select a flash or rotation pattern:
1. Press and hold the push button for one second to switch
to the next pattern in the sequence (Table 1).
2. Press and hold the push button for three seconds to set
the beacon back to the first pattern (Steady).

Maintenance
Lens and dome replacement
WARNING: Electrocution hazard. To prevent electrical shock,
disconnect the beacon from the supply circuit and allow five
minutes for stored energy to dissipate before disassembling.
Caution: Do not overtighten the screws or damage to the
dome may occur.
To replace the lens or the dome:
1. Remove the four screws from the dome and lens
assembly, and then remove the dome and lens as shown
in Figure 1.
2. Make sure the O-ring is in place around the base of the
unit, and replace the lens and dome.
3. Reinstall the four screws and tighten each firmly until the
gasket slightly compresses between the dome and the
screw head.
Cleaning
Caution : To prevent damage to the lens or dome, do not use
abrasive materials or cleaners.
Periodically clean the lens surface with a soft cloth and water
or a mild detergent solution to maintain optimum light visibility.
Ensure that the lens is completely dry before assembling the
beacon.
