ProFire PF2200-SB Installation Manual page 14

WIRING
The wiring in this section is required for all PF2200 installations. Skipping or performing any steps in this
section incorrectly will result in the PF2200 functioning improperly. Conduct pull tests on terminating wires in
the BMS to ensure proper installation. Install tags identifying that electrical seals have not been poured on
electrical connectors entering the PROFIRE BMS.
POWER
The PF2200 can be powered from 12V or 24V. The maximum current that the PF2200 can safely handle
without blowing the main fuse is 10A. The system on its own draws about 100mA. The rest of the current is
used by additional hardware such as valves. Make sure that you select a power supply that is rated
appropriately for the total amount of current that is consumed by the system, and all devices attached to it.

PILOT VALVE OUTPUTS (Pilot 1 & Pilot 2)
Two powered outputs (terminals 15-16 and 17-18) are intended to be connected to solenoid valves which
control the fuel line for the pilots. When Pilot 2 is enabled, both outputs work in conjunction with one
another. Meaning that they open and close in unison. If Pilot 2 is disabled, the Pilot 2 output stays
deenergized. The Pilot Outputs are capable of peak and hold PWM output mode at a fixed 3 kHz frequency.
Supported duty cycles for PWM mode are 10-100% and are configurable via the user interface. Depending on
the selected input type, the Pilot valve has a maximum of 5 amps and 12 / 24 volts.
MAIN VALVE OUTPUTS (SSV)
Two powered outputs (terminals 19 and 20) are intended to be connected to solenoid valves which control
the fuel line for the main burner. Both outputs work in conjunction with one another. Meaning that they open
and close in unison. The Main Valve Outputs are capable of peak and hold PWM output mode at a fixed 3
kHz frequency. Supported duty cycles for PWM mode are 10-100% and are configurable via the user
interface.
