The procedures and replacement of parts mentioned in this section should be
performed only by trained, authorized personnel. The access covers on the
Front Panel are not interlocked – turn off and disconnect power before remov-
ing the cover.
1. Turn off system power to the robot.
2. Turn off power to the optional SmartController EX, if you are using one.
3. Disconnect the cable between the Front Panel and the eMB-40R (or controller).
4. Remove the Front Panel from its mounting location.
5. Remove the two screws on the back of the Front Panel.
Save the screws for re-installation.
6. 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 out as possible. You do not have to disconnect
the wires from the PC board, although you can if needed.
7. 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.
8. The lamp body is now free. You can remove the old lamp and insert a new one.
9. Re-install the lamp body by pushing it straight into the lamp housing receptacle. Make
sure the contacts on the lamp body are properly oriented, as shown in the following fig-
ure.
10. Make sure to reconnect the wires from the LED if you disconnected them earlier.
11. 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.
12. Re-install the two screws on the back of the body.
