PF3100 TROUBLESHOOTING – SOLUTIONS TO COMMON PROBLEMS

Main flame fail

The main flame ion failed to detect flame after the main valves opened.

Solution:

Check that the main flame detect rod is positioned in the flame. Test the ion input DC and AC voltage levels.

Confirm main gas is flowing.

Level or pressure contact range error

The input to the level or pressure input is out of bounds from what is expected. The signal may be too low (in the

case of 4-20mA input) or too high.

Solution:

In the case of the 4-20mA signal check the current and confirm it is within range (4 to 20mA). If used as a digital

input, check that the voltage does not exceed the input range of 12 or 24VDC depending on the system power

supply.

Feature Key Alarm

The feature key is not present or is the incorrect one for the system.

Solution:

You can confirm the feature key details in settings > Setup > Feature Key menu. Here a feature key status is

available that shows if the key is currently detected, is invalid or has a fault. A list of system restrictions is shown

for items such as pilot per controller, IO per appliance and number of controllers per appliance. If any of these

items are violated a feature key alarm will be set.

Low or High voltage warning

If low the system voltage is below it's desired operating range. If the voltage continues any lower the system will

shutdown. If high the system voltage is above its desired operating range. If the voltage continues any higher the

system will shutdown.

Solution:

Confirm the voltage settings match the power supplied to the system by going to Settings > Setup > System

Voltage. The Controller voltage should match the input power of the system. Check with a multi-meter that the

power supplied to the system is correct – either 12 or 24VDC. If the voltage drops when the valves turn on

confirm the power supply is sized appropriately for the current load.
