The igniter function is activated with a 24 VDC triggering signal from the burner management system
(terminals 3, 4 on Fig. 4 and 5). Once energized, the green "IGNITION" indication LED on the enclosure door
will light. The 24VDC control signal from the Burner Management System operates an internal relay which
powers the HV ignition transformer, which in turn creates an 8,000 VAC spark at the igniter tip.
In case another triggering voltage is needed contact Fireye.
After the Trial for Ignition, the control signal is switched off, the relay changes state to allow ionization
detection to indicate presence of flame.
This signal from the ionization rod is connected to
MBCE-110/230FR
flame sensor module in
HTSS-PP
or
HTSS-PP-CEX
power packs, which provides an isolated Flame Relay signal.
The
MBCE
module, also provides a 4-20 mA signal to display flame intensity (see the Fireye Instruction
Manual no
MBCE-1001
). Be aware that for proper ionization measurement a pilot body should be properly
constructed and connected (grounded) to the ionization circuit terminals in power pack (see Fig. 4 or 5).
