Process Firing System
PFS, PFF, PFR, PFP
Construction
The system is based on plug-in panel modules which are installed in a 19”
sub- rack. The sub-rack is then wired to provide the system required for the
specific application. Primary power to the system is switchable between
110/120 V AC or 220/240 V AC. The same power is also supplied to the burner
control units for control of the air and gas solenoids via relay contacts and
for the semiconductor output to the ignition transformer. The power supply
module generates the 24 V DC control logic voltage.
General technical data
Mains voltage switchable: 110/120 V AC, -151+10%
50/60 Hz 220/240 V AC, -15/+10%, 50/60 Hz
for earthed or non-earthed networks. Mean switching cycle dependent on
power factor cosign approx. 1 x 106.
19” card as Euro sized card with plastic
front panel:
Front width:
8 TE 1.6 inch (40.6 mm).
Height:
3 HE 5 inch (128.4 mm).
E type plug connection to IEC 603, 48- pole.
Installation position: any.
Ambient temperature: -4° F to 140° F (-20° C to +60° C), no condensation
admissible.
PFS, PFF, PFR, PFP
- 19” rack
- A large choice of different sub-racks giving various applications in
accordance with the customer’s specification - High integration
- UV detector or flame rod circuitry
- Each card with its own power supply (115 V AC and 230 V AC
interchangeable) - Can be directly controlled by process control computers with 24 V DC
- Flame signal can be measured on the front panel without shutting down
the burner - All cards are FM approved
