Fit Procedure; Sequence; Sequence Procedure - Honeywell P531 Operating Manual

MODELS P531, P532 AND P532UI OPERATING MANUAL

Fit procedure

1. Using the channel menu procedure (above) se-
lect the AUTOMATIC menu branch by toggling
to yes using the UP or DOWN buttons and press
STORE.
2. If prompted to turn off a sensor, use the UP or
DOWN button to display the sensor that is to be
turned off then press SELECT to turn it off.
3. If prompted to UNCAL a channel (see note
above), press the STORE button to answer the
YES? Query to acknowledge the side effect this
will have on the other channel.
4. Using the UP or DOWN buttons, scroll to FIT
and press SELECT to select the automatic fit
procedure.
5. If TURN FLAME ON is displayed (the flame re-
lay is not energized) turn the flame on. Calibra-
tion will not continue without the flame relay be-
ing energized.
Note: Calibration cannot be done with the flame
relay off. Prior to entering the Automatic menu suffi-
cient flame/gain combination must be available to
ensure the flame relay will be energized.
6. Fit calibration will take less than 17 seconds. A
countdown timer will display the maximum re-
maining seconds.
7. Completion of Fit calibration will display:
AUTO FIT OK! Completion of successful gain cali-
bration. New gain parameters are stored and the
display will revert to default display.
LOW FLAME SIGNAL Insufficient flame signal to
allow for optimal flame count output. Install orifice
with larger hole. Original calibration will be re-
stored.
HIGH FLAME SIGNAL flame signal too strong to
allow for optimal flame count output. Install orifice
with smaller hole. Original calibration will be re-
stored.
GAIN REJECTED Number. If the unit cannot attain
appropriate gain calibration within the time allotted
"REJECTED" will be displayed along with the type
of gain being adjusted and the processors best
guess for gain calibration.
Page 7
A rejected gain calibration can occur if fluctuations
of signals are detected during calibration or if the
signal is such that the gain cannot be determined
automatically.
Note: In certain cases acceptable results may be
obtained by manually setting the gain to the proces-
sors best guess and then re running the procedure.

Sequence

Auto Sequence configures the gain and relay set
points for a specific channel.
When entering the auto sequence configuration, the
auto fit procedure (above) will be automatically per-
formed first.
Once the proper gain setting has been established,
the system will take samples of the flame to eliminate
flicker error.
Flame on will be sampled for 60 seconds and flame off
(dark) will be sampled for 60 seconds.
Flame sample times can be shortened by pressing
a button. However, a minimum of 10 seconds is
required. If the RESET button is held for 1 second
the procedure will abort.

Sequence Procedure

1. Using the channel menu procedure above, se-
lect the AUTOMATIC menu branch by toggling
to yes using the UP or DOWN buttons and press
STORE.
2. Using the procedure outlined in Fit Procedure
above, follow all steps except SELECT SE-
QUENCE from step 4 above.
3. Once the Fit portion of the Sequence calibration
has been successfully completed:
4. START BURN YES? Question will be asked,
press the STORE button to start the 60-second
count down for the flame on (bright) portion of
the calibration.
5. Flame samples times can be shortened by
pressing a button for 1 second. However, a mini-
mum of 10 seconds is required.
