instructions are correct, common sense and good engineering practice shou d a ways be used to adapt to specific site
requirements. Training in the use of the 8100/ 8200 Monitor can be provided by Partech, p ease contact sa es for
further information.
1.2 Product Description
The 8100 Monitor is a sing e channe instrument for use with one sensor. It provides a sing e a arm re ay output and a
sing e fau t re ay output. The a arm set point and de ay are configured using contro s mounted on the front pane . The
status of the input channe is indicated by three LED’s.
The 8200 Monitor has two input channe s for use with two sensors. It provides two a arm re ay outputs (one for each
channe ) and a sing e fau t re ay output. The fau t re ay is used to indicate a fau t on either input channe . The 8200
Monitor has two pairs of set point and de ay contro s and two sets of status LED’s. The a arm set point and de ay for
each channe can be independent y set and the status of each channe is indicated separate y.
The 8100/ 8200 Monitor has an IP65 rated enc osure and is suitab e for outdoor use, however, a protective cover or
outer enc osure is recommended to further protect the instrument from harsh environmenta conditions.

1.2.3 Fault Indication
Fau t indication is via the i umination of a status LED that is c ear y visib e on the front pane of the monitor. When
there is a fau t present the orange FAULT LED i uminates.
1.2. Alarm Activation
When the sensor is c ear and not in a fau t condition then the green OK LED is i uminated. If however, the sensor is
obscured or b ocked then the re ay wi enter into the a arm condition and the red ALARM LED wi become i uminated.
1.2.5 Delay Operation
A de ay can be introduced between conditions for an a arm turning on being met and the re ay changing state. At any
time during a de ay, if the conditions for turning the a arm on are removed, then the de ay wi end and the a arm re ay
wi not change state. The de ay can be set between 1 & 90 seconds. The de ay function is in p ace to try to avoid the
occurrence of fa se a arms that may be caused by suspended debris.

1.2.6 Alarm Relays
The a arm re ays are interna y configured for fai safe operation. When power is app ied and the sensors are c ear the
re ays wi be energised, on a arm the re ays are de-energised. Each a arm has norma y c osed and norma y open
contacts for externa signa ing, the norma condition is when the unit is powered and the a arm is off.
1.2.7 Fault Relay
The fau t re ay is uti ised when there is a prob em with the sensor or a ternative y there may have been a power fai ure
to the system and in this instance the re ay wi be de-energised and therefore send the monitor into a fau t state
1.3 Applications
The 8100 & 8200 Monitors, when combined with a compatib e sensor, are designed for use as a s udge b anket eve
detector, a s udge density switch, or as a suspended so ids/turbidity switch. The 8100 & 8200 Monitors are therefore
suitab e for interfacing with automatic de-s udging contro of primary and secondary sett ement tanks, thickener contro
and high and ow b anket eve a arm, or as a simp e a arm in a water/ waste water f ow.
1.3.1 Sludge Blanket Level Detection
When used for this operation the monitor uses an IR or ST series sensor, which is suspended by its cab e to the
desired monitoring depth in the tank. When the sett ed s udge reaches the sensor then the a arm output is activated.
This can then be used as an input to a process system to direct y contro pumps, be mouths or simp y to a ert the
operator. The same princip e can be used to monitor when the s udge reaches a minimum point when it is being
removed from the ho ding tank.
1.3.2 Suspended Solids Switch
The 8100/8200 Monitor can be used as a suspended so ids switch when used in conjunction with the IR and ST series
sensors. The sensor can be insta ed in an eff uent channe to detect a va ue of suspended so ids and give a high
a arm.

a setpoint and a de ay adjustment contro and a so on the front pane are the three status indicators:
OK – Green LED
ALARM – Red LED
FAULT – Orange LED
.1 Setpoint
The type of sensor used determines the measurement/detection range of the system. It is however possib e to do
some fie d adjustment and fine tuning of the system once insta ed.
By turning the setpoint contro from fu y anti-c ockwise to fu y c ockwise it is possib e to a ter the setpoint from 5 - 95%
of the range of the sensor.
.2 Delay
The de ay contro is used to a ter the ength of time after an a arm condition occurs that the a arm re ay is activated.
Once an a arm condition ends, the de ay wi a so determine how ong the a arm re ay remains in the a arm condition
before deactivating. The de ay can be set between 1 and 90 seconds and is used to prevent fa se a arms being
indicated. For examp e when the sensor signa momentari y goes above the a arm va ue due to unrepresentative
debris.
To increase the ength of de ay the contro marked DELAY on the front pane of the 8100/8200 Monitor shou d be
turned c ockwise. When turned fu y c ockwise the de ay is set at 90 seconds.

5 Sludge Blanket Level Detection
5.1 Description
The typica s udge b anket eve detection insta ation is in a sett ement tank. The system is made up of a sing e or dua
sensor configuration and a monitor. There wi a so be associated mounting hardware, which is dependent upon the
app ications requirements.
The monitor is typica y mounted on a handrai on the bridge of a sett ement tank. The sensor is suspended by its
cab e; though it shou d be noted that the sensor must be fastened to the fixing point provided by the mounting bracket
and is not eft to hang from the cab e g and at the base of the monitor.
When mounting the monitor and sensor on a sett ement tank with rotating bridge, the sensor shou d norma y be
ocated on the eading edge, approximate y ha f way between the centre and outside edge of the tank, as shown
above. Care shou d be taken when mounting the sensor to ensure that it does not trai into the scraper.
5.2 Sensor Installation
Once the bracket/monitor has been attached to the handrai via the sadd e c amps and U-bo ts and the sensor has
been connected to the monitor, it is then a matter of passing the cab e through the various retaining c amps and
owering it into the sett ement tank to the desired depth at which the s udge b anket is required to be detected. When
assessing mounting options, attention shou d be paid to the accessibi ity of the sensor for ca ibration and
maintenance, stabi ity of the sensor in the f ow conditions present on site and it must a so be ensured that when
mounting the sensor it is fu y submerged at a times.
The sensor can be suspended by its cab e, but the top end of the cab e must be fastened to a fixed point. It shou d be
noted that the sensor must not be a owed to hang direct from the cab e g and at the bottom of the monitor.
5.3 Monitor Configuration
When supp ied the factory mid-point settings may not be suitab e for the required app ication. If this is the case then
the fo owing procedures shou d be undertaken
5.3.1 Blanket not detected
If the sensor is not detecting the s udge b anket and the green OK ight remains on when the sensor is in the b anket,
take the fo owing action:
•With the sensor in the s udge b anket, the setpoint contro shou d be turned anti-c ockwise s ow y unti the red
ALARM LED i uminates. This indicates that the sensor has detected the s udge b anket.

5.3.2 Blanket continually detected
If the sensor is continua y detecting the s udge interface and the red ALARM LED stays on when the sensor is above
the s udge b anket the fo owing action shou d be taken:
•With the sensor above the s udge b anket, set the de ay to the minimum, then the a arm point contro shou d be
s ow y turned c ockwise unti the green OK LED i uminates. This indicates that the sensor is correct y, not
detecting the s udge b anket.
Note: If the setpoint contro is turned fu y c ockwise and the detector continua y indicates the presence of the s udge
b anket when the sensor is above the b anket, the sensor that is fitted is too sensitive and an a ternative sensor wi
have to be fitted
For accurate adjustment of the setpoint to a required eve :
1. Immerse the sensor fu y in a known samp e of the required va ue.
2. Turn the a arm point contro fu y anti-c ockwise; the green OK LED shou d i uminate.
3. The a arm point contro shou d be turned c ockwise unti the red ALARM LED i uminates.
The desired a arm point has now been set and the contro er wi now detect s udge b ankets of this va ue or higher.
Note: In the event of the sensor being changed, it wi be necessary to repeat the above a arm point adjustment in
order to obtain accurate resu ts
