I) GENERALITIES
The SPX monitors and displays the dust emission behind a filter, based on the
triboelectric effect. It’s made with two main units self connected. It gives the trend of dust
emissions as a % or as a quantity (mg/m3or other).
- The sensor: - installed in the duct or the duct to be monitored
- its extremity is projected into the particle flow
- monitored the signal
- The control unit : - receives the data from the sensor
- averaging measure
- converses with the user (display, keys)
- automatic zero calibration
- stores and dates the datas (1 month of recordings)
- commands the alarm
- an output 4-20 mA (in option) of the trend
The SPX 100 can be connected with a PC (line RS232 and software in option) directly or
through a telephone MODEM
- remote viewing / configuration
- reading of the stored datas
- graph operation, reports creation, etc ...
- storage in disk files format
- graph display in continuous (real time)

III) CONNECTIONS
1) Sensor
The sensor is fitted on the duct or the duct to be monitored:
- Filetage 1" BSP (26-34 GAS)
- Placed on a rectilinear position (5 diameters before / 2 diameters after mini -
N.B. : If stack : 5 diameters after)
- grounded metallic duct (5 meters before the sensor mini). The continuity of earth
between the sensor and the section of casing must be ensured.
- The sensor length must be adjusted to the duct.

2)Base
To access the terminal blocks, put off the connections cover
NOTE : The relay contacts are drawing main supply « off ».
When the supply voltage comes « on », the relay pulls up if no alarm.

* SUPPLY CHOICE
(To access this, put off the front panel and the upper board)
BE CAREFUL : The SPX 100 leaves our workshops for a 230V supply voltage.
WARNING :
If you change the supply voltage, you must update the data plate located on the outside of the box.

IV) RUNNING
1) General
A measure, always made by the sensor, is transmitted to the base to be interpreted and
stored.
The base has two types of memory :
- A working memory :
Refreshed each second
Calculate the average measure on an adjustable duration from 1 to 60 minutes
- A storage memory (in option) :
Stores the last 1 month datas (scrolling memory)
1 storing each minutes
To calculate the average value of the dust concentration on 1 month maxi
(see « average calculation on 24 hours »)
Possibility to read the datas via a PC :
- Incident analysis
- graphics outputs
- Report outputs
- etc ...
Display of the instantaneous and averaged trend (from 1 to 60 mm) in mg/m3, µg/m3or %
of full scale (see «measure reading adjustment»).
If the mg/m3or µg/m3unit is choiced, it's necessary to calibrate the device with a known
or estimated dust concentration (e.g. mass measurement).
All the adjustments need a user password (adjustable).

2) Alarm
The SPX 100 has an adjustable alarm threshold (see « alarm adjustment »).
Each time, the averaging value (1 to 60 min) is compared with the alarm threshold, the
alarm is activated when the average is above the alarm threshold :
- The DEFAULT relay pulls down
- The « bargraph » on front panel is flicking
The alarm is even held if the measure downs again the alarm threshold.
To cancel the alarm, the user must :
- Press the « alarm » key and keep it pressed
- Press the « valid » key (see « alarm adjustment »)
(option of a non maintained alarm: please consult us)
3) 4-20 mA (in option)
The 4-20 mA output scale is adjustable.
The 4-20 mA output recopies the instantaneous measure or the average measure according
to the display (see « measure reading adjustment »).
4 mA for 0 measure,
20 mA for the value of the 4-20 mA input scale.
4) Connection
Each time the base communicates with the sensor via a bi directional digital data link. If
there is a problem (cutted cable, bad connections, component failure), this message
appears: CONNECTION FAULT
SENSOR
In this case, the 4-20 mA output becomes à 0 mA and the DEFAULT relay pulls down.
This message disappears if there is no problem.
