5.1 Changing the Lamp in the High Power Indicator
The system is equipped with circuitry to detect the potentially dangerous condition of a
burned out High Power indicator on the Front Panel. If this lamp is burned out, you
cannot enable High Power until the lamp has been replaced. Follow this procedure to
replace the High Power indicator bulb. The Adept part number for lamp is 27400-29006.
1. Turn off system power to the SmartController.
2. Disconnect the cable between the Front Panel and the SmartController.
3. Remove the Front Panel from its mounting location.
4. Remove the two screws on the back of the Front Panel.
5. Carefully pull the front cover away from the body of the Front Panel. You will
encounter some resistance as there are three plug-type connectors that you need
to disconnect as you pull the front cover away from the body.
NOTE: Separate the cover from the body slowly to avoid damaging the
two wires that go between the LED and the PC board inside the body.
Pull the front cover as straight away as possible. You do not have to
disconnect the wires from the PC board, although you can if needed.
6. Locate the lamp body in the center of the back side of the front cover. Turn the
lamp body approximately 20° in either direction and then pull straight back.
7. The lamp body is now free. You can remove the old lamp and insert a new one.
8. Replace the lamp body by pushing it straight into the lamp housing receptacle.
Make sure the contacts on the lamp body are properly oriented. See Figure 5-1 on
page 86 .
9. Make sure to reconnect the wires from the LED if you disconnected them earlier.
Push the front cover into the body, taking care to align all of the plug-type
connectors. Verify that the wires do not get crimped as you reinstall the cover.
10. Replace the two screws on the back of the body.
11. Reinstall the Front Panel in its mounting.
12. Reconnect the cable between the Front Panel and the SmartController.
