MODELS P531, P532 AND P532UI OPERATING MANUAL
DESIGN FEATURES OVERVIEW
The Models P531and P532 feature a new design
in flame monitoring technology. The dual processor
system is capable of monitoring three viewing heads
simultaneously. It can also monitor both UV and IR
separately from one S55xx viewing head. In addition,
three marginal alarm relays can be configured to pro-
vide a secondary indication if the flame count falls be-
low set point or if a viewing head temperature reaches
70° C (158° F).
The P532 and P532UI makes use of three scrolling
dot matrix displays capable of displaying alphanumeric
characters in three different colors as follows:
Red
indication for IR
Green
indications for UV
Orange
indication for mixture of UV and IR
The P531 Signal Processor uses seven discrete
LED’s for display. These include:
Tricolor flame strength flashing indicators for each
channel.
Relay and status indicators.
In addition to automatic viewing head detection, each
channel and viewing head can be associated with two
sets of configuration data as follows:
1.
Primary:
This is the normal viewing head con-
figuration.
2.
Alternate:
This is a set of alternate settings that
can be activated by applying a voltage across
the alternate select pins for each specific chan-
nel or writing configuration to Modbus register.
Automatic set up functionality is a feature whereby
each channel can be configured automatically in one
of three ways:
1.
Auto Fit
: The flame is monitored and the gain is
adjusted to produce an optimal count of between
1100 and 1300. The flame on will then be set at
800 and flame off will be set to 600.
2.
Auto Sequence
: The gain will first be adjusted
as in the Auto Fit routine and then the flame on
and flame off settings will be adjusted. (This
requires turning off the flame).
3.
Auto Filter
: Used for definitive infrared calibra-
tion. The sequence procedure (above) is per-
formed on each of the 8 filter settings. The best-
differentiated filter is chosen and configured for
gain, flame on and flame off settings.
The P532 provides the use of a lockable front panel
for restricting unauthorized access. The P531 uses the
removable P532UI to achieve this feature.
Both Signal Processors have viewing head error de-
tection with viewing head lockout capabilities. (this
requires user intervention)
A P522 operation mode can be achieved by installing
a jumper between the two P522 pins.
Changing viewing head types (while the system is
operational) will cause the processor to go into lockout
mode. (This is a safety feature).
The P531 and P532 are compatible with RS-422 and
Modbus protocol, and are field upgradeable with firm-
ware download capabilities.
Viewing Head Selection.
Models S702 / S802 IR and the S706 / S806 UV
viewing heads can be connected to Viewing Head #3.
Viewing head #3 will default to be assigned to chan-
nel “A”.
Models S552 IR and S556 UV together with the
S550 that utilizes both UV and IR sensors can be con-
nected to Viewing Head #1 and #2.
Viewing Head #1 will default to be assigned to
channel ‘B”.
Viewing Head #2 will default to be assigned to
channel “C”.
Note: Alternate channels default to NONE
USER INTERFACE OVERVIEW
The P532 front panel and the P532UI (User Interface)
makes use of nine push buttons for operation. Each
of these buttons has at least one specific purpose.
All access to the front panel operation is initiated by
pressing and holding a button for two seconds (this
eliminates the possibility of inadvertent access).
In all cases, only the available options will be dis-
played.
