INTRODUCTION

The ET-16 (incandescent and LEDs) and ET-17 (neon) indicating lamps consist of a common receptacle, plug in type resistors and lamps, escutcheon, and color cap. They are available for mounting on switchboard panels up to and including ¼ inch thickness.

APPLICATION

These lamps can be used whenever a panel mounted signal or indicating lamp is desired.

The ET-16 is available for either one brilliance or dim bright operation when incandescent lamps are used. ET-16 lamps are also available with Light Emitting Diodes (LEDs). The incandescent type can be easily upgraded to the LED type. It only requires acquiring the appropriate color LED and lens cap and inserting into the lamp receptacle.

The ET-17 can be used when extra long life is a factor and brilliance is not. It also can be used when low current is desired.

FEATURES

1.The simple “push-twist” type plug has been adopted for both the bulb and the resistor. This was accomplished by incorporating a bayonet base on both components.

2.A common receptacle for both the ET-16 and ET-17 coupled with the plug-in resistor and bulb makes it easy to change on the panel without disassembling.

3.The resistor is in series with the bulb, and the ohmic value for the different circuit voltages is designed at 80% of the rated bulb voltage to give it longer life. Changing voltages is easily accomplished by changing the series resistor (see listed tables for the proper resistor).

4.A short circuit plug is available when a series resistor is not required or if an external resistor is to be used.

5.The ET-16 uses GE Catalog No. 1819 for the 24 DC lamp and GE Catalog Number 1835 for the balance of the ratings. For LED types, long life LEDs (100,000 hours) are specified. Additional features are as follows: reduced heat, resistance to shock and vibration, improved safety, lower current, cost savings, and no cold filament inrush current. The LED lamps come in red, green, and amber colors. White is not an option because a white light LED is not available. ET-17 uses GE Catalog Number B1A.

6.Terminals are readily available. They are designed for either AMP “FASTON” type connectors, solder, or screws.

7.Nine basic color caps designed for maximum visibility are available for ET-16 incandescent types. Five Translucent caps: red, green, yellow, white; and four transparent caps: amber, red, green, blue, and clear. For ET-16 LED types, only the transparent lens caps are recommended. This is because the transparent lens allows more LED light to pass through than the translucent lens cap used on incandescent lamps. The available colors are as follows: red, green, amber, yellow smoke, clear and blue.

ET-17: Because of the special properties of neon, only amber, transparent red, and clear lenses are suitable.

The color caps have a knurled OUTSIDE DIAMETER FOR EASY REMOVAL.

8.The ET-16 is also available for dim bright applications.

9.When special voltage or resistance is required other than those listed, a special lamp may be ordered with the proper design, or designated series resistor.

10.A two-inch insulating washer is supplied with each indicating light. It should be mounted on the inside of the panel as illustrated in Figs. 2, 3, and 4. The function of this washer is to provide additional insulation between the terminal and ground (panel) if a surge were to be induced on one of the potential leads.

If a bulb other than those listed above is required, the lamp will be furnished less the bulb. Listed tables give some of the specials made available.

CONNECTIONS

See Figure 1A and 1B for typical tell-tale and dim-bright connections.

RECOMMENDED PANEL ASSEMBLY

Thread the pal nut against the shoulder of the receptacle. Install the two-inch insulating washer on the front of the receptacle against the pal nut. Insert the receptacle through the panel and thread the escutcheon nut against panel. Install the color cap and hand tighten (do not force). Turn the escutcheon nut back up against the color cap, then back off ½ to ¾ turn (¾ turn recommended) to give at least 1/64 inch clearance but not more than 1/32 inch clearance between the color cap and escutcheon nut (for up to 3/16 inch panel). For the ¼-inch panel, the color cap will be flush with the escutcheon nut. Tighten the pal nut against panel to 10 to 12 inch-pounds of torque.
