Alerts and there meaning
Problem
System has visible flame but
cannot detect
Card is unresponsive or BMS
card will not communicate
with User Interface card
Ignition transformer "clicks"
but no visible spark
DOC-001041 / v1.0
, refer to the PF2200 ALERT
Diagnosis
1. Ensure pilot assembly, flame rod, and the gap
between are fully engulfed in flame. If not, adjust
rod position
2. Ensure flame detection wiring does not exceed the
recommended maximum
3. Ensure burner assembly has a low impedance path
to Ion- terminal of BMS
4. For longer run lengths, ensure ignition cable is
used to avoid ground-loading
1. Ensure the Status LEDs for both cards are functioning. If
status LED is not functioning, cycle power (if safe to do
so) and check again.
2. If status LED is still not functioning, attempt a firmware
update of both cards.
3. If firmware update fails, card is likely faulty.
1. Ensure all wires in the ignition path are properly
terminated and that there is a low impedance path
from the primary-windings to the BMS card as well as
the secondary-windings to the ignition rod.
2. Ensure the gap between the ignition rod and the
burner housing is within the tolerances specified in
this manual under PF2200 Declarations section under
"High Voltage Spark Gap Range". Often times there is
either excess buildup or the rod has drooped to
compromise the gap distance.
