1. Introduction
Functional Description
The PROFIRE PF3100 Modbus RS-485 card allows the PF3100 system to interact with other devices, such as PLCs
and SCADA networks that support RS-485 two wire (half-duplex) communication via Modbus RTU Protocol. This
card is always a Modbus slave device. Separate Modbus master devices can start/stop the system, read system
status and process values, and modify settings.

Terminal Descriptions
Power, Common
Input power 12/24 VDC, 6.3A max.
EGND
Internally connected to Common; must be wired to a nearby Earth Ground.
RS-485 D+/D-
-7V to 12V absolute.
+/- 3VDC differential recommended.
The baud rates supported are from 9600 baud to 19200.
RS-485 Reference (Terminal 10)
Shared common ground with customer PLC. Must be wired in.
Terminator Selector Switch
The termination selector switch is used to apply a 120ohm resistance to the signal. By applying this resistance,
it in turn “terminates” the signal. It should only be used when you want to terminate the signal.

8. Preventative Maintenance & Inspection
In order to ensure that the Modbus card works correctly and efficiently, the following maintenance and inspection
procedures should be followed:
➢Ensure that all wires are connected correctly.
➢Minimize copper wire exposure.
➢Check for corrosion and ensure that no wires are frayed or worn out, and all insulation is intact.
➢Confirm no moisture or condensation is apparent on the board or in the enclosure.
➢Ensure that the board does not show any sign of mechanical damage (e.g. –damage from an impact such as
dropping an item).
➢Ensure that the board does not show any sign of electrical damage (components should not be burnt or
damaged in any way).
➢Check that the device is not subject to excessive vibration.
➢Confirm that the temperature of the board is within ambient temperature operating limits.
➢Check that the enclosure is secured and that the device is not subject to excessive vibration.
➢Routine inspections of all equipment should be performed. If any abnormality is found, corrective actions should
be taken. If the abnormality cannot be corrected, contact PROFIRE.

➢A qualified technician should perform any tests necessary to confirm that the equipment is still in a safe
condition.
Cleaning
If the card becomes dirty it can be cleaned with compressed air. Do NOT use solvents, cleaners, or liquids to clean
the board. Caution must be exercised when cleaning the board in order to prevent damage from ESD (electrostatic
discharge).
Replacement Parts
Please contact PROFIRE should any replacement parts be required.
9. Important Safety Information
Before installing the PF3100 Modbus card, please review the list of warnings below. Product use in a manner not
specified by PROFIRE is not recommended. Failure to observe the following warnings may result in death,
electrocution, property damage, product damage, product damage, government fines, or malfunction of the
product itself.
WARNING: Explosion Hazard
➢Do not disconnect while circuit is live unless area is known to be non-hazardous or equivalent.
➢Substitution of components may impair suitability for specified zones.
➢Do not service unless the area is known to be non-hazardous.
➢Do not open when energized.
➢Installation and use must conform to the directions in this guide.
➢System must be properly connected to earth-ground for effective operation of flame detection circuitry.
Installation Warnings
➢Ensure that the PF3100 enclosures are securely closed each time after opening the enclosure. This protects
the internal circuitry from moisture damage and other environmental concerns. Moisture damage is not
covered by the product warranty.
➢Do not connect wires or handle the device when powered.
➢Properly fuse the board according to local codes.
➢Do not disassemble or modify the board in any way. The board is not field repairable and must be sent back to
PROFIRE for replacement if damaged.
