PRODUCT OVERVIEW
The DIGIMATIC is a  xed point Level Controller incorporating a microcomputer which is used to automatically
calibrate the probe to suit the material being detected. Full manual override facilities are included.
The DIGIMATIC employs a power shield to minimise the e󰀨ect of material adhering to the probe making it
ideal for detecting most materials including sticky or viscous types. It is equally suited to both liquids and
solids. The probe may be a solid rod, metal plate or wire rope. The self contained DIGIMATIC is normally
supplied with a loose probe, available as a stainless steel rod in standard lengths of 100mm, 1 metre or 2
metres, or as a 10 metre wire rope suspension probe and weight.
The probe should be screwed to the DIGIMATIC. Prior to attachment, the probe length can be reduced or
increased, if desired, but see notes a) and b) regarding minimum surface area.
NOTES:-
The DIGIMATIC sensitivity is proportional to the surface area of the probe. When using a 16mm dia. probe the minimum length
to use, for the majority of materials, is 200mm. This should be treated as the minimum if
possible.
If the probe length needs to be reduced to less than 200mm, the surface area should be maintained. This can be achieved by
increasing the diameter, by tting a metal tube over the probe, or by bending the probe rod. In certain high density materials it
may be possible to reduce the length without compensation.

INSTALLATION
A thread locking compound is already applied to the probe xing stud of the Digimatic. This will prevent the
probe rod from vibrating loose. Once tted, the compound is fully hardened after 20 minutes.
IMPORTANT: If the probe rod is removed from the unit for any reason, a thread locking compound must
be applied before the rod is retted.
When mounting all versions of the Digimatic, care must be taken to ensure that the power shield is properly
installed.
DIGIMATIC will operate on 110V/230V ac 50/60Hz or 24V dc supplies. The unit may be wired in ordinary
un-screened cable of any length and need not be separated from other cables.
A SUPPLY EARTH IS ESSENTIAL!
When mounting the DIGIMATIC, care must be taken to ensure that the exposed end of the power shield
protrudes into the container.
Mount unit securely to minimise vibration. Connect in accordance with the standard wiring diagram, and
set High/Low switch to required position (see below), ensure that cable gland and back cover are fully
tightened when nished. The DIGIMATIC has two 20mm cable entries, one of which is blank, the blank
may be drilled out carefully if required; it must not be knocked out.
The unit should be wired and earthed in accordance with appropriate Electrical Regulations. The unit must
beearthedandtheterminalMUSTbe bonded to the earth bond stud.Onmetalcontainers,unitearthMUST
be bonded to the container. If the container is non-metallic, metal  anges or couplings used to mount probe
should be bonded to earth. This also applies to probes mounted in wooden or plastic tops of metal bins.
Fail Safe Setting
The “High/Low” switch, sets the fail safe mode. In the “High” position, the relay is de-energised with material present. In the
“Low” position, the relay is energised with material present. Normally, the “High” position is used for high level probes and the
“Low” for low level probes. Intermediate probe settings depend upon individual requirements.
WARNING
Proper spacing of the power shield is vital for correct operation. For questions regarding proper spacing
of the power shield to the vessel wall, contact 4B.

PAGE 10
FAIL SAFE SETTING -
The “High/Low” switch (D - Image D), sets the fail safe mode. In the “High” position, the relay is energized
without material present. In the “Low” position, the relay is energized with material present. Normally,
the “High” position is used for high level probes and the “Low” position for low level probes. Intermediate
probe settings depend upon individual requirements.
ELECTROSTATIC RISK - Ensure that the enclosure is not subject to charging in end application.
PARK MODE -
In normal operation, the LED display shows a value representing the capacitance measured by the probe
at the time.
Pressing and holding the “Probe Covered / Raise” button (E - Image D) will cause the display to
show CXXX followed by RXXX.
Pressing and holding the “Probe Un-Covered / Lower” button (F - Image D) will cause the display
to show UXXX followed by RXXX.
CXXX is the probe covered value measured during calibration, UXXX is the uncovered value and RXXX is
the relay operating point which theAuto-Set calculates and is half way between the two measured values.
NOTE
In park mode, settings are “View Only” and cannot be altered.

CAL MODE (AUTO/MAN SWITCH SET TO AUTO) -
In this mode, pressing and holding the “Probe Covered / Raise” button (E - Image D) with the probe
covered, will cause the unit to measure and display the covered value, and recalibrate the relay
operating point if necessary.
Pressingandholdingthe“Probe Un-Covered / Lower” button(F-ImageD)withtheprobeuncovered,
will cause the unit to measure and display the uncovered value, again recalibrating the relay
operating point if necessary.
CAL MODE (AUTO/MAN SWITCH SET TO MAN) -
In this mode, pressing and holding the “Probe Covered / Raise” button (E - Image D) will cause the
display to momentarily display the present relay operating point and then to increment the setting
slowly and then rapidly to set a higher operating point.
Pressing and holding the “Probe Un-Covered / Lower” button (F - Image D) will cause the display
to momentarily show the current relay operating point, and then decrement the setting, slowly and
then rapidly.
Once adjusted in manual mode, any previous settings will be lost. The CXXX reading will be 1 above the
relay operating point and the UXXX reading 1 below.
NOTE
Always return to “Park” after calibration.

PAGE 12
SENSOR CALIBRATION
The Digimatic can be calibrated automatically, manually or by a combination of the two methods.
Usually, automatic calibration is the simplest method, particularly when the vessel can be lled to cover
the probe.
Manual calibration is useful when a number of probes in similar applications need to be set. Once the
correct calibration has been determined and noted, on one system, the remainder can be set to the
same setting.
AUTOMATIC CALIBRATION (MATERIAL AVAILABLE) -
1. Set Park/Cal switch (A - Image D) to Cal and Auto/Man switch (C - Image D) to Auto. The Cal
LED will ash.
2. Ensure that the probe is uncovered and press and hold the “Probe Un-Covered / Lower”
button (F - Image D) button. The display will show UXXX followed by RXXX.
3. Fill the vessel su󰀩ciently to cover the probe and then press the “Probe Covered / Raise”
button (E - Image D) button. Display will show CXXX followed by RXXX.
4. Return the Park/Cal switch (A - Image D) to park. The unit is now calibrated. UXXX and
CXXX values can be viewed but not altered by pressing the “Probe Un-Covered / Lower” and
“Probe Covered / Raise” buttons.
SEMI-AUTOMATIC CALIBRATION (MATERIAL NOT AVAILABLE) -
5. Follow steps 1 & 2 above.
6. Set Cal/Park switch (A - Image D) to Park and press the “Probe Un-Covered / Lower” button
(F - Image D) button. Note the UXXX reading but ignore the RXXX reading. Return the Cal/
Park switch (A - Image D) to Cal and set the Auto/Man switch (C - Image D) to Man.
7. From Table A below, select the nearest material type to be detected for your application and
add the value to the UXXX reading determined in step 6.
8. Press the “Probe Covered / Raise” button (E - Image D) button to raise the reading and
the “Probe Un-Covered / Lower” button (F - Image D) to lower the reading to achieve the
calculated setting from step 7.
9. Return the Cal/Park switch (A - Image D) to Park and press and hold the “Probe Covered /
Raise” button (E - Image D) to conrm that the relay operating point RXXX is correctly set.
The UXXX and CXXX settings will be one below and one above the readings.

TIME DELAY -
The Auto-Set has an adjustable delay from 0 to 60 seconds, the timer operating on both material arriving
and leaving.
To set the time delay, proceed as follows:
10.Set the Cal/Park switch (A - Image D) to Cal.
11.Press and hold the timer button (G - Image D), the display will show T000 (zero delay). To
set a time delay, continue to hold the timer button and the display will start to increase by
1 second increments (maximum delay is 128 seconds). When the required delay time is
shown, release the timer button. To reset the delay, press and hold the timer button again to
restart the entire process from T000 (zero delay).
12.Return the Cal/Park switch (A - Image D) to Park and press the timer button (G - Image D) to
conrm the timer setting.
13.The timer can be altered to a longer or shorter delay by repeating the entire procedure from
steps 10 to 12.
NOTE
For questions regarding non-standard Digimatic probe lengths or diameters, contact 4B.

PAGE 14
POWER SHIELD OVERVIEW
The Digimatic detects material by radiating a high frequency (RF) signal from the probe. The advanced
electronics of the Digimatic use this signal to measure the capacitance inside the vessel with respect to
ground and thus indicate when material has reached the Digimatic probe.
The power shield creates a barrier and enables the unit to ignore a certain amount of material built up on
the probe, helping to prevent false readings. The Digimatic’s standard power shield is 121mm in length,
with options for a 160mm and 221mm available on request. Other specic lengths may be available.
Please contact us for more information.
The standard (121 mm) power shield can be used with walls that are up to 115 mm (4.5 inches) thick.
Installation through thick concrete silos only requires a 25.4 mm (1 inch) diameter hole for probe
insertion.
NOTE
The actual amount of material build up that the Digimatic is able to ignore is dependant upon several
factors, including the density of the material, the moisture content of the material and the type/style of
the vessel.

PAGE 15
TESTING AND COMMISSIONING
1. Check that the unit is correctly installed (see standard wiring diagram).
2. After going through the sensor calibration steps, the green LED should be “ON”.
3. Introduce material to the Digimatic. If calibrated correctly, the Digimatic will activate when material
has been detected. Machinery shut down will depend on your specic monitoring setup. 4B
recommends an instant shutdown when maximum ll level or a plug condition has been detected.
WARNING
If the system does not immediately shutdown as expected or alarm as required, then remove the
machine from service until the problem has been diagnosed and corrected.
