FEATURE OVERVIEW

PERIPHERALS

The PF3100 system can be configured to operate as a parallel positioning fuel/air ratio control system for forced draft

applications. In addition to the standard fuel train, the following peripherals are required:

▪A fuel gas control valve (TCV) where valve position is controlled by a 4-20 input signal. The valve must

have a 4-20 output signal for position feedback.

▪An air damper or VFD blower where damper position/VFD speed is controlled by a 4-20 input signal. The

damper or blower must have a 4-20 output signal for position/speed feedback.

▪A proof of airflow switch or 4-20 transmitter. Airflow must be proven from the blower for the system to

start.

Additionally, the following IO are available, but are not required for the system to operate.

▪A fault input may be enabled on the IO expansion module. This will take in a digital signal from either

the motor driver or damper positioner. Often these devices have an output that triggers in the case of a

fault event (over-torque, over-heat, etc.). If the signal is high the system will operate normally. If the

signal is low or open the BMS will alarm and shutdown.

▪The BMS has a powered output that can be used as a signal output to turn a blower on/off. This output

will turn the blower on or off accordingly for the system state. It is often used when variable air flow is

controlled by a damper.

STATUS SCREEN

Once initial configuration is complete, adjustments to settings can be accessed from the Appliance Status Screen. The

Status screen will show the following information. Clicking on any of the FARC labeled items will open the FARC

configuration dialog.

Inputs

▪FARC Valve –This shows the current valve

position feedback. An out of range input is

displayed by an “N/A”.

▪FARC Damper –This shows the current

damper/fan feedback.

Outputs

▪Firing Rate –This shows the current requested

firing rate for the system

▪FARC Valve –This shows the BMS’s currently

requested valve output.

▪FARC Damper –This shows the BMS’s currently

requested damper/fan output.

ALERTS

All system alarms including any FARC related alarms are annunciated on the alerts screen. These include any configuration

or input faults related to the FARC settings or physical I/O.

▪The alerts screen shows any currently

annunciated alarms, system waits or

warnings.

▪An alarm may be selected and opened on the

alerts screen to show a more detailed

description of the related system issue.

▪System events including alarms and

shutdowns are recorded in the PF3100 event

log.

FUEL AIR RATIO TABLE

The fuel air ratio table has a total of 21 points of adjustment for each fuel and air curve. The adjustment points are located

at 5% increments across the firing rate 0 to 100% range. The table may be adjusted in 1% increments.

▪A minimum of 1 point is required to start the

system.

▪Points may be added at any 5% interval by

highlighting the firing rate column and

pressing any of the OK, +, - or number pad

buttons.

▪All entries must be greater than or equal to

the previous point. This enforces an

increasing Fuel air slope.

▪A user entered point is highlighted in black.

▪Values between user added points are linearly

interpolated. These values are shown in a

grey font.

▪Points may be removed by highlighting the

column and pressing the OK button, then

selecting remove point from the pop-up dialog.

▪The plus (+) and minus (-) buttons will increase

or decrease the highlighted point in 1%

increments.

INSTALLATION GUIDE

Installation and commissioning must be performed by a qualified technician with experience in commissioning and tuning

Forced draft positioning type FARC systems. Regular maintenance should be performed on the system to verify the tuning

and correct system operation.

The PF3100 FARC system uses analog 4-20mA and digital on/off signals to control external devices. The following table

outlines IO operation. Connect the BMS IO to the corresponding peripheral. Wiring diagrams for common installations

are available from Profire. In addition to this table any IO expansion card inputs may be configured to be used as fault

alarms for peripheral equipment. Commonly these will be configured as an additional fault feedback from a motor driver.

FARC COMMISSIONING

Prior to configuring FARC, make sure the BMS system has been configured per the installation. This may include

configuring temperatures, ignition modules, fuel gas pressure transmitters, level transmitters, etc.

FARC specific settings have a level 3 authentication. Please contact Profire for the password to modify these settings.

CONFIGURING THE IO EXPANSION MODULE

The following instructions provide an overview of how to configure the IO expansion module required for FARC control.

Open the IO expansion wizard: System Overview

Settings > IO Expansion wizard. In the Add Inputs tab:

▪Add a FARC Valve Position input.

▪Add a FARC Damper Position input.

▪Add the FARC Valve to input 1 and the FARC

Damper to input 2.

▪Set the 4-20mA output to Damper Position

Controlled by FARC. A dialog will appear with

additional FARC configuration settings. See

the FARC Settings section for a detailed

description of setup. The Fuel Air table, light

off position and minimum firing rate can be

adjusted later. All other settings can only be

set in this screen as they should only be

configured in commissioning and not during

operation.

▪The IO expansion module can be set to a 12V

or 24V mode –select the voltage appropriate

for the type of peripherals used. If unsure, use

12V mode.

▪Go to the review tab and confirm there are no

configuration errors.

▪Accept the changes and close the wizard

HOW TO ADJUST FARC SETTINGS AFTER INITIAL COMMISSIONING

▪Open the FARC Configuration Dialog by selecting one of the FARC IO in the appliance status screen. The

FARC IO will highlight red, simply press OK to select it.

▪All settings are set to a read only state by default. To change them the FARC Mode must be set to

Manual.

▪Adjust the settings as desired. The changes will take effect immediately. The return or finished button

may be used to close the dialog.

▪If the system is left in Manual mode a warning will be displayed on the alerts screen.

▪Not all settings can be adjusted from this screen. Settings that are read only can be adjusted from the IO

wizard. This includes the start up positions of the valve and damper and all error configuration.

FARC CONFIGURATION DIALOG SETTINGS

The following settings are available for adjustment in the settings dialog. This is accessible from the appliance status

screen by selecting and pressing the OK button on any of the FARC labeled IO. All FARC related settings are level 3

password protected unless otherwise noted.

Some settings such as the manual firing rate, light off position and minimum firing rate are weakly enforced with respect

to each other. This means that once the values are within a valid range, they will be prevented from moving outside of

that range by the user interface. If the values are outside of a valid range (for example due to a reset to defaults), they can

move across the full range until they fall within the valid range. This allows for adjustment of these settings if they are

configured incorrectly, but also allows for them to be easier to change by the operator during operation without tripping

a configuration error.

0% to

10%

This is the maximum allowable error from the

requested valve or damper position as

compared to the feedback valve or damper

position. If the error is not satisfied within the

Position Error Timeout time, the system will

alarm and shutdown.

Cross Limit

Error (%)

0% to

15%

This is the maximum allowable difference that

the fuel position may exceed the air position. If

this difference is exceeded for a time longer

than 2 seconds the system will alarm and

shutdown. Effectively this is the percentage of

excess fuel position that is allowed within the

tolerance of the system. In the opposing case

where the air position is greater than the fuel

position the system will not shutdown as this is

not an inherently dangerous situation.
