    To check your firmware version, do the following with the PF2100 powered on. Simultaneously hold both the Up and Down buttons on the keypad. If the firmware version of any card does not meet minimum requirements, contact Profire to arrange for a firmware upgrade.

  • Page 6: Description

    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.

    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.

    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.

  • Page 11: Procedure When No Expansion Card Is Preinstalled

    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.

  • Page 12: Transmitter Requirements

    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.

    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.

    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.

    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.

  • Page 19: Calibrating The "Level" Current Loop

    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. The transmitter can be powered from the loop. 3. The system has a high degree of immunity to industrial noise which might superimpose voltage offsets onto the loop. PF2100 4-20mA Input Card User Manual v1.2 June 2, 2021 ©2021 Profire Energy Inc...

  • Page 22: Appendix B - Using The Pf2100 Menu System

    Appendix B – Using the PF2100 Menu System Menu Structure The menu system (for door card firmware E1.8.217) is comprised of a status menu followed by six numbered menus containing the system settings and other information. When the system is powered on, it will default to displaying the status menu. Each menu has a number of menu items. The menus are:...

    Setting the System Voltage The PF2100 can be programmed to expect either 12V nominal or 24V nominal for its power source using menu 4.8. This setting only affects the under voltage and over voltage alarm points that the system uses. It does not in any other way affect the system. The PF2100 electronics are designed to operate correctly from about 8.5V to 32V regardless of this menu setting.
