Why does the QEL cycle 3 times with a solid red led and does not work?

Improper mechanical adjustment or QEL calibration could cause the QEL cycle three times with solid LED and not work. First check mechanical adjustment on vertical rods or mortise lock device and correct adjustment. (Note, this procedure is for the QEL, and does not apply to the QELa. The QELa is self calibrating)
To calibrate the QEL:

• Apply power and wait until the LED is solid red.
• Momentarily press the calibration push button ( LED will flash green).
• QEL will go through a retraction sequence to complete calibration, LED will be solid green and latch bolt retracted.
• Remove and reapply power to verify correct operation.
