4.1 Changing the Lamp in the Front Panel 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 lamp. The Adept part number for the 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.
WARNING: Lockout and tagout power before servicing.
WARNING: The procedures and replacement of parts
mentioned in this section should be performed only by
trained, authorized personnel. The access covers on the
SmartController are not interlocked – turn off and
disconnect power if covers have to be removed.
