Description
The 4-20mA Input Card is an Expansion Card designed for use with PF2100 Burner Management Systems. It provides two separate 4-20mA Analog Current Loop
Receivers, one for Level and one for Pressure, each of which can be enabled or disabled using a DIP switch on the card. The third loop, the “Auxiliary” Current
Loop, is not supported by firmware:
1. “Level” Current Loop
2. “Pressure” Current Loop
3. “Auxiliary” Current Loop (Not Supported)

“Level” Current Loop
The “Level” Current Loop is designed to control a pump and heater system that pumps liquid into a heated tank. The 4-20 input card will sense the level of liquid
in the tank and shut off the pump when it is full. It will also de-energize all valves if the tank is empty to prevent damage to the tank.
The level can be displayed on the PF2100 control panel and can be read remotely over Modbus using a Modbus Expansion card (sold separately).
A normally open status contact and a normally closed status contact are provided for use as a high level shutoff for the pump and/or to control external alarm
circuitry.
A software selectable low and high setpoint can be programmed into the PF2100. The PF2100 will de-energize all valves if the level drops below the low level
threshold. Exceeding the high level threshold will toggle the status contacts but will not shutdown or otherwise affect the operation of the burner control
system.
Three LEDs are also provided on the card to indicate if the 4-20mA Level loop is connected, if the level is below the low setpoint, and if the level is above the high
setpoint.
“Pressure” Current Loop
The “Pressure” Current Loop allows the main valve train pressure to be monitored. If the pressure is lower than the low threshold or higher than the high
threshold, the system will de-energize all valves. The PF2100 can also be configured to control the main valves based on the low-pressure input. Three LEDs are
also provided on the card to indicate if the 4-20mA pressure loop is connected, if the pressure is below the low setpoint, and if the pressure is above the high
setpoint.
“Auxiliary” Current Loop
This input is not currently supported by any firmware revision.

If your system did not have a 4-20mA Input Card pre-installed at the factory, follow these steps to install it.
Otherwise, skip to the next section of this document.
Procedure When Another Expansion Card is Preinstalled
1. Shut off the power to the PF2100 system.
2. Remove the 4 machine screws from the expansion card that is already installed in your PF2100 system. See Figure 3.
3. Remove the 4 machine screws and 4 standoffs from the new 4-20mA card that you are about to install. See Figure 4.
4. Attach the 4 standoffs to the expansion card that is already installed in your PF2100 system. Tighten to 4 in*lbs. Do not over tighten or the standoffs
may break. See Figure 5.
5. Carefully install the new 4-20mA Input Card on top of the existing expansion card such that the long pinned header on the 4-20mA Input Card mates
with the socket on the old expansion card. Be careful not to bend any pins while doing this. Continue to apply pressure to the 4-20mA Input Card until
the header is fully inserted. See Figure 6.
6. Finish attaching the new 4-20mA Input Card to the old expansion card using the 4 machine screws that were previously removed. Tighten to 4 in*lbs.
See Figure 6.
7. You are done installing the card! You should have the following extra parts left over which you can either discard or keep for future use: 4 machine
screws and 4 hex nuts.

Procedure When No Expansion Card is Preinstalled
1. Shut off the power to the PF2100 system.
2. Remove the 4 screws that hold the terminal card in place in the product enclosure. Do not lose these screws as you will need them later. See Figure 7.
3. Carefully install the 4-20mA Input Card onto the Terminal Card such that the long-pinned header on the 4-20mA Input Card mates with the socket P1 on
the Terminal Card. Be careful not to bend any pins while doing this. Continue to apply pressure to the 4-20mA Input Card until the 4 standoffs fit into
the holes in the PCBA. See Figure 8.
4. On the back side of the Terminal Card, install 4 hex nuts onto the standoffs to hold the 4-20mA Input Card in place. Tighten to 4 in*lbs. Do not over
tighten or the standoffs may break. See Figure 8.
5. Place the terminal card back into the product enclosure and fasten it using the 4 screws removed previously. Tighten to between 12 and 26 in*lbs taking
care to not leave screws loose enough that the terminal card rattles around and not too tight that the enclosure holes begin to strip out. See Figure 7.
6. You are done installing the card! There should not be any extra parts left over. If there are, double check if you have missed a step.

Transmitter Requirements
Level and Pressure Transmitter Requirements
Any 4-20mA level or pressure transmitter will work with the 4-20mA Input Card. It is, however, important to take into consideration the following two items
when selecting a transmitter:
1. Minimum Operating Voltage –Some transmitters have a relatively high minimum operating voltage. Check that the transmitter will work with your
current system voltage to ensure an easier integration. A detailed explanation of how to do this can be found below.
2. Level Transmitter Mounting Height Compensation –Some level transmitters are programmable so that the mounting height of the transmitter relative
to the tank bottom can be compensated for. Some versions of PF2100 firmware (E1.8.202 and higher) have a feature called “Level Offset” that will allow
you to compensate for this in the PF2100 settings.
Transmitter Supply Voltage
Different transmitters will have different power supply requirements. It is important to verify what these requirements are before wiring up the system. If the
supply voltage is not high enough, the 4-20mA output of the transmitter may not function properly as it gets closer to 20mA or it may cause the PF2100 system
to report a level error.
To determine the minimum supply voltage for the PF2100 (VPF2100_MIN in volts) required to properly operate a given transmitter, first lookup the minimum
operating voltage (VTRANSMITTER_MIN in volts) from the transmitter’s datasheet. Then plug that number into the following equation to determine the minimum
supply voltage that will guarantee proper operation across the entire 4-20mA output range. VPF2100_MIN is the voltage required at header P7, terminals
“12/24VDC” and “Common” on the Terminal Card.
Equation 1:     
If powering the transmitter from a separate power supply, and not via. the 4-20mA Input Card, use the following equation to determine the minimum supply
voltage (VSUPPLY_MIN in volts):
Equation 2: 
    
Use Equations 1 and 2 when troubleshooting your device to ensure you have enough voltage to properly operate over the entire range of your transmitter.
Example Ignoring Cable Length
As an example, the “Rosemount 2088 Gage and Absolute Pressure Transmitter” has a datasheet minimum operating voltage requirement of 10.5V. Using
Equation 1 above, this would require a minimum voltage supply of 14.94V for proper operation. There are three ways to achieve this:

PF2100 4-20mA Input Card User Manual v1.2
©2021 Profire Energy Inc
June 2, 2021
Page 9
1. Run the PF2100 on 15V –When the PF2100 is configured through its menu for 12V operation, it can safely run on anything from 10V-15.5V without
causing a low or high voltage alarm. It is therefore safe to set the system to run from 15V and connect the transmitter up to the “12/24V” pin on the 4-
20mA Card which will output 15V.
2. Run the PF2100 on 24V –Many transmitters can run on a system voltage of 24V or higher. The Rosemount 2088 can run on as much as 36V. If you
change the PF2100’s menu settings to expect 24V using menu 4.8 and then change its power supply to 24V, the “12/24V” pin on the 4-20mA Card will
also output 24V which can be used to power the transmitter.
3. Use a Separate Power Supply –The PF2100 and the transmitter can run from separate power supplies if desired. The PF2100 can run from 12V or 24V
and the transmitter can run from some other voltage source as required. If you do this, ensure that the external supply has a common ground
connection with the PF2100 using a chassis ground or the ground pin provided on the 4-20mA Input Card.
Compensating for Cable Length
If your cable length is very long (>500 feet) and/or your wire gauge is very narrow (>16 AWG), you may also need to account for the DC resistance of the cable
(RCABLE). In most cases, the cable resistance is negligible and can be ignored (RCABLE = 0).
To account for cable resistance, first add up the total length of cable (LCABLE in feet) that runs from the voltage supply to the transmitter, from the transmitter to
the 4-20mA Input Card’s “Level” input, and the length of ground wire running from the Input Card back to the voltage supply.
Equation 3:       
You will then need to look up the DC resistance from the cable’s datasheet which is typically specified in Ohms per thousand feet at a given gauge and for a given
type (stranded vs non-stranded). Plug this into the following equation to determine the DC resistance of your cable:
Equation 4:  

Then use the corresponding equations to determine the minimum supply voltage. If powering the transmitter via. the 4-20mA card use Equation 5, if powering
the transmitter from a separate power supply use Equation 6:
Equation 5:         
Equation 6: 
        
Example Compensating for Cable Length
As an example, let’s again consider the Rosemount 2088 but this time with a non-negligible 1000 feet of 20 gauge stranded wire. If the wire had a datasheet
resistance of 11 Ohms per thousand feet, using Equation 5, the new minimum voltage supply would be 15.16V (0.2V higher than before).

Electrical Wiring
The following steps should be followed to wire up the pluggable header on the 4-20mA Input Card. More detailed instructions for each step can be found later
in this section of the document.
1. Disconnect power from the PF2100 to prevent accidentally shorting any component of the system.
2. Remove the pluggable header from the 4-20mA Input Card.
3. Wire up the “Level” Current Loop using either the onboard or an external power supply.
4. Wire up the “Level” Status Contacts if required.
5. Wire up the “Pressure” Current Loop using either the onboard or an external power supply.
6. Ensure that nothing is connected to the “Auxiliary” Current Loop input.
7. Replace the pluggable header back onto the 4-20mA Input Card and ensure that it is fully inserted.
8. Reconnect power to the PF2100.
The Pluggable Header
The terminal block on the 4-20mA card includes a pluggable header. You may find it easier to wire up if you first
remove the pluggable header from the 4-20mA Input Card by pulling it out as shown in Figure 9.
The pluggable header has set screws to loosen or tighten the wire cages on the front of the connector. Turn the screw
clockwise to raise and thus tighten the cage. Turn the screw counter clockwise to lower and thus loosen the cage.
Wires should not be stripped longer than 9mm to prevent bare conductor from being exposed after
insertion into the terminal block.
Insert each wire fully into the front of the pluggable header and then ensure that the corresponding set
screws are tight enough to securely clamp the wires in place.
Connecting the “Level” Current Loop Using the Onboard Power Source
If after consulting the “Transmitter ” section of this document you have determined that it is acceptable
to use the 4-20mA Input Card’s Onboard Power Source, then wire the pluggable header according to
Figure 10.

Connecting the “Level” Current Loop Using an External Power Source
If after consulting the “Transmitter ” section of this document you have determined that it is necessary to
use an External Power Source, then wire the pluggable header according to Figure 11.
Connecting the “Level” Status Contacts
The “NO” (normally open) contact is closed (connected to the “COM” pin) when the level input is below the
high setpoint and is open (not connected to the “COM” pin) when it is equal to or greater than the high
setpoint. A common use for this contact is to control a pump that is designed to pump liquid into the tank
until it is full.
The “NC” (normally closed) contact always has the opposite status of the “NO” contact. A common use for
this contact is to turn on an indicator light or send a signal to a remote location when the tank becomes full.
Figure 12 shows an example of how to wire the contacts to a pump and indicator lamp as
described above.
IMPORTANT: Be sure that you do not exceed the current rating of the contacts with whatever
equipment you hook up. Use relays if you need to switch higher power devices.

Follow these steps to configure the menu settings for the 4-20mA Card:
1. If you are unfamiliar with the operation of the PF2100 menu system, review the “Appendix B –Using the PF2100 Menu System” section of this document
before proceeding further.
2. Ensure that the 4-20mA card is enabled using menu 6.1. Menu 6.1 should end with the word “Yes” if configured correctly.
3. Perform the following steps if you intend to use the 4-20 level input:
a. Ensure that the Level DIP Switch is enabled on the 4-20 Input Card.
b. Set the level units that are applicable to your installation using menu 6.2. These are the units that you want the PF2100 to use when displaying
readings from the 4-20mA “Level” input.
c. Set the tank’s maximum volume level using menu 6.3. This is the level at which the tank is full and results in 20mA on the “Level” input.
d. If the level transmitter is not mounted at the very bottom of the tank, use menu 6.4 to specify the offset.
e. Set the Low Level setpoint using menu 6.5. This is the level below which the system will alarm.
f. Set the High Level setpoint using menu 6.6. This is the level above which the system will toggle the High Level status contacts.
4. Perform the following steps if you intend to use the 4-20 pressure input:
a. Ensure that the Pressure DIP Switch is enabled on the 4-20 Input Card.
b. Set the pressure units that are applicable to your installation using menu 6.7. These are the units that you want the PF2100 to use when
displaying readings from the 4-20mA “Pressure” input.
c. Set the maximum pressure of the fuel train using menu 6.8. This is the pressure at which the transmitter will output 20mA.
d. Set the Low Pressure setpoint using menu 6.9. This is the pressure below which the system alarms.
e. Set the High Pressure setpoint using menu 6.10. This is the pressure above which the system alarms and shutdown.

Calibrating the “Level”Current Loop
If your Level Transmitter is programmable, you should first verify that it is calibrated correctly. You should ensure that the transmitter outputs 20mA when the
tank is full and 4mA when it is empty. Alternatively, if your transmitter is not mounted at the bottom of the tank, you may want to program it to output more
than 4mA to indicate the volume of liquid that may be present in the portion of the tank below the transmitter. For some firmware versions, a Level Offset
feature is available which may be used to accomplish this.
After initial installation, the “Level” input on the 4-20mA Input Card needs to be calibrated. The calibration data is stored in non-volatile memory on the Door
Card, not on the 4-20mA Input Card itself. For this reason, Input Cards cannot ship from the factory pre-calibrated. This calibration procedure should be
repeated whenever the Door Card or 4-20mA Input Card are replaced.
There are three steps to calibrating the “Level” Current Loop:
1. Calibrate the Level Transmitter.
2. Calibrate the Zero Point for the “Level” Input on the 4-20 Input Card.
3. Calibrate the Span (Max Point) for the “Level” Input on the 4-20 Input Card.
The calibration of the 4-20mA input card is done in Menu 7. To unlock the calibration menu hit the up and down arrow keys simultaneously.
Calibrating the Level Transmitter
This procedure will differ from device-to-device. In general, you may require a handheld process calibrator such as the Fluke 725 and a HART protocol
programmer. Consult the documentation for your Level Transmitter to determine the proper procedure for calibrating your device.
Calibrating the Level Input’s Zero Point
To calibrate the Level Input’s Zero Point, you will need a handheld process calibrator such as the Fluke 725. Follow this procedure to calibrate the zero point:
1. Navigate to Menu 7 and press OK. Cycle through the submenu items until “4-20 Level Zero Calibration = No” is displayed on the PF2100.
2. Press the Up or Down key to begin the calibration process. The display will now read “Apply 4mA then press OK”.
3. Turn on the process calibrator and set it to source a current of 4mA (0%).
4. Disconnect the wire from the “Level” input and instead attach the process calibrator’s positive lead in its place.
5. Connect the process calibrator’s negative lead to the ground pin on the 4-20mA Input Card.
6. Press the “OK” key on the PF2100. The message “Calibrating Wait…” will appear for several seconds followed by the message “Parameter Set” after the
calibration has successfully completed.
7. Disconnect the process calibrator and reconnect the wire that was removed in step 4 to the “Level” input.

Calibrating the Level Input’s Span (Max Point)
To calibrate the Level Input’s Span (Max Point), you will need a handheld process calibrator such as the Fluke 725. Follow this procedure to calibrate the zero
point:
1. Navigate to Menu 7 and press OK. Cycle through the submenu items until “4-20 Level Span Calibration = No” is displayed on the PF2100.
2. Press the Up or Down key to begin the calibration process. The display will now read “Apply 20mA then press OK”.
3. Turn on the process calibrator and set it to source a current of 20mA (100%).
4. Disconnect the wire from the “Level” input and instead attach the process calibrator’s positive lead in its place.
5. Connect the process calibrator’s negative lead to the ground pin on the 4-20mA Input Card.
6. Press the “OK” key on the PF2100. The message “Calibrating Wait…” will appear for several seconds followed by the message “Parameter Set” after the
calibration has successfully completed.
7. Disconnect the process calibrator and reconnect the wire that was removed in step 4 to the “Level” input.
Calibrating the “Pressure” Current Loop
To calibrate the Pressure Current Loop, follow the same procedure as described for calibrating the Level Current Loop but use the corresponding Pressure inputs
and menu items.
