Preventative Maintenance & Inspection - ProFire PF3100 Series Product Manual

DIP Switches
Grounded: The signal is internally grounded in the PF3113-00 IO Expansion board.
Floating: The signal is repeated out through the Signal Out port adjacent to the corresponding Signal In port.
This signal must be terminated by the customer. The floating state is not safety rated.
8. Preventative Maintenance & Inspection
In order to ensure that this product works correctly and efficiently, the following maintenance and inspection
procedures should be followed:
➢ Ensure that all wires are connected correctly
➢ Minimize copper wire exposure.
➢ Routinely check for corrosion.
➢ Wires must not be frayed or worn, and all insulation must be intact.
➢ Ensure that no moisture or condensation is apparent on the board or within the enclosure.
➢ Check that the board does not show any sign of mechanical damage (e.g. – damage from impact from a
dropped item such as a screw driver).
➢ Confirm that the temperature of the board is within ambient temperature operating limits.
➢ Check that the device is not subject to excessive vibration.
➢ Routine inspections should be performed on all equipment. If any abnormality is found, corrective actions
should be taken. If the abnormality cannot be corrected, contact PROFIRE as soon as possible.
➢ A qualified technician should perform any tests necessary to confirm that the equipment is still in a safe
condition. The board may be tested for correct operation in a safe, non-hazardous environment as follows:
•
The Dry Contact outputs can be tested by putting them into a run status mode.
o When the system is in a non-running state, the N.O. contact will be open and the N.C. contact
will be closed.
o When the system is in a running state (started or in a wait state) the N.O. contact will be
closed and the N.C. contact will be open.
•
The 4-20mA Output can be set to manual mode. The operation can be tested by setting different
output percentages through a multimeter or load.
•
The 4-20mA Inputs can be tested by sending a known good 4-20mA input signal into them. The value
can be read on the PF3100 Appliance Status Screen. The range alarms can be checked by setting the 4-
20mA signal out of range or by opening the signal.
•
The Digital Inputs can be tested by sending a logic high (board PWR Out to the signal in). This will show
as closed on the Appliance Status Screen. Open the input – this should show as open on the Appliance
Status Screen.
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).
