Commissioning a New LME7 Burner Control

1. Ensure all devices are properly connected to the LME7. See Section 2 (LME71...), Section 3
(LME73...), or Section 4 (LME75...) of this manual for more information on wiring devices to the
LME7 burner control.
2. Install the PME7 program module into the LME7 burner control. Apply power to the LME7.
3. The LME7 will alternately display "rSt" and "PrC", indicating that the parameter set from the
PME7 program module needs to be restored into the LME7 burner control. To do so, press and
hold the info button on the LME7 burner control until the LED on the LME7 turns yellow, then
release. This should take approximately three seconds.
4. The word "run" will briefly be displayed. Then, the display will alternate between "rSt" and
"End". This indicates that the restore process was successful.
5. Press and hold the info button for approximately two seconds to reset the LME7. If everything
was done properly, the LME7 should now display "OFF".
6. If any LME7 parameters need to be changed from their default values, an AZL23 display unit is
required. Plug in the AZL23 display unit.
7. To log in to the LME7 and access the parameters, press and hold the F and A buttons
simultaneously on the AZL23 until the word "CodE" appears.
8. Enter the password for the desired access level. The default passwords are:
LME71... / LME73... Service Level Password – 7173
LME75... Service Level Password – 7576
LME7... OEM Level Password – L7un
9. Set all parameters as necessary for the application.
(LME73...), or Section 4 (LME75...) of this manual for more information on setting the
parameters in the LME7 burner control.
10. If using an LME73... or LME75... burner control with an actuator, the limit switches on the
actuator must be set. The most common actuator used with the LME7 is the SQM4x.x8xxxx. On
the SQM4x.x8xxxx actuator, set the red cam (I) for the desired high fire position. Set the blue
cam (II) for the desired low fire position. If using PME73.812A1 or PME75.812A1, which allow
for an independent ignition position, set the orange cam (III) for the desired ignition position. If
using an actuator other than the SQM4x.x8xxxx, see the actuator literature for more
information on setting the limit switches.
11. At this point, the LME7 burner control is fully commissioned. It is recommended to perform a
parameter backup to synchronize the parameter settings of the LME7 burner control and PME7
program module. See the next section for instructions on performing a parameter backup.
