1. Removing Proflo PF1 batteries.
2. Hold down the set button for 45 seconds. Holding the set button discharges
internal capacitors and ensures a complete reset.
3. Re-insert the batteries to reboot the Proflo PF1.
*If the error was a one-time problem the Proflo PF1 will reboot as normal.
*If on reboot the diagnostics detect an error, the Proflo PF1 will display the con-
stant RESET error again. Replace the Proflo PF1 and contact Ariel Corporation.
Sometimes on reboot the Proflo PF1 will flash reset. This is normal.
RESET 1 -The Proflo PF1 processor was not able to determine if the EEPROM contains valid
configuration information. Reset 1 is most likely to occur after a RESET 3 is reported. Upon
Proflo PF1 reboot the stored configuration data will be lost and the programmed information
will need to be reentered.
RESET 2 - The Proflo PF1 processor was not able to determine if any data has been stored
or where the next data should go. Upon Proflo PF1 reboot the stored data will be lost. Con-
figuration data will still be there and the programmed information will not need to be reen-
tered.
RESET 3 - This is an internal Proflo PF1 fault. The Proflo PF1 processor tried and failed three
resets. The most likely cause is failure to write to the EEPROM.
NOTE: THE MOST LIKELY CAUSE OF RESET ERRORS IS MOISTURE ON THE PRO-
FLO PF1 CIRCUIT BOARD. SEVERAL DESIGN PRECAUTIONS HAVE BEEN
TAKEN TO KEEP WATER AND MOISTURE OUT OF THE CIRCUIT BOARD
CHAMBER. THESE INCLUDE:
1. The Proflo PF1 housing has been completely sealed in a low humidity room and
will survive a 2300 psi (160 bar) power wash.
2. There is a desiccant pack in the circuit board chamber.
3. The circuit boards have a protective conformal coating.
Proflo PF1 Operation Notes:
1. If the alarm output is set for NC operation and the batteries are removed or go
dead the Proflo PF1 will open the alarm contact. If the alarm operation is set to
NO operation and the batteries are removed the alarm contact will remain in the
open condition and the control system will not be told to alarm. For this reason
Ariel recommends using the NC contact operation.
2. Proflo PF1 Default programmable settings.
This is as delivered to Ariel or reset using the FFT software.
Alarm trip time = 120 seconds
NC/NO settings = NO or non-fail safe
Ariel shop work instructions set outputs to:
Alarm trip time = 120 seconds
NC/NO settings = NC or fail-safe
