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.
