An external security interlock is available on the Surelite. An example of its use is the user
who wants to install an external interlock on the lab door.
Figure 42 External plug
The important thing to remember is that once the external interlock is active, continuity must be
maintained between pins 1 & 9 of the external D connector. If continuity is broken, E06 error
message is displayed and the system shuts down. This D connector is labeled
EXTERNAL and is
located on the front panel of the PCU (see page 58 ).
To enable external interlock
1. Flip the red toggle switch labeled AC POWER on front of PCU to the up (ON) position.
2. Turn the keyswitch counter clockwise to the ON position.
3. Press the SELECT button for Q-SW. DELAY. The red LED next to the label Q-SW.
DELAY will be illuminated.

Press ARROW UP button until 999 is reached.

Continue to press for an additional 20 seconds or until an audible beep is heard.
4. The external interlock is now activated.
5. Note: Remember that continuity between pins 1 & 9 is necessary for operation or error
message E06 will be displayed.
6. While the system is still in the Q-switch delay mode, use ARROW DOWN button to return
Q-switch value to original setting found on the QA page at beginning of the manual.
