LOCKOUTS
When a safety shutdown occurs, the control LEDs indicate the reason for the lockout. The alarm cir-
cuit (Terminal “3”) is energized. The non-volatile memory remembers the status of the control even
if a power failure occurs. By momentarily depressing and releasing the manual reset button on the
control or Terminal 21 remote reset, the control can be reset. The button must be held down for one
second and then released. Very little force is required to do this. Do not press hard.
RESETTING THE CONTROL
The BurnerPRO system contains 2 methods of reset: Push button reset and remote terminal reset.
The remote reset should be a normally open switch connected from line voltage to terminal 21 (see
example wiring diagrams).
•
Reset is required following a non-volatile lockout.
•
Depressing the push button reset momentarily causes the system to recover from a lockout.
•
Depressing and releasing the reset button during run mode causes the control to go into lockout.
•
The BurnerPRO limits the amount of remote reset attempts to 5 tries in a 15 minutes window.
BURNERPRO LED ERROR / LOCKOUT CODES
During an alarm condition, the status LED turns solid red. The remaining LEDs are illuminated as a
coded sequence identifying the reason for the lockout. The following table shows the various LED
Lockout codes:
Boiler operation, maintenance, and troubleshooting shall only be conducted by trained personnel. Persons trouble-
shooting lockouts or resetting the control must respond properly to troubleshooting error codes as described in this
product bulletin.
Jumpers being used to perform static test on the system must only be used in a controlled manner and must be
removed prior to the operation of the control. Such tests may verify the external controllers, limits, interlocks, actua-
tors, valves, transformers, motors and other devices are operating properly. Such tests must be conducted with man-
ual fuel valves in the closed position only. Replace all limits and interlocks not operating properly, and do not bypass
limits in interlocks. Failure to follow these guidelines may result in an unsafe condition hazardous to life and prop-
erty.
