Page 6: Product Overview
PRODUCT OVERVIEW The DIGIMATIC is a fi 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 effect of material adhering to the probe making it ideal for detecting most materials including sticky or viscous types. -

“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 8... -
Page 9: Standard Wiring Diagram
STANDARD WIRING DIAGRAM All wiring must be In accordance with local and national electrical codes and should be undertaken by an experienced and qualified electrician. A thread locking compound is already applied to the probe fixing stud of the DIGIMATIC. This will prevent the probe rod from vibrating loose. Once fitted, the compound is fully hardened after 20 minutes. -

SENSOR OPERATION Image D 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”... - Page 11 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.

Page 12: Sensor Calibration
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 filled 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. - Page 13 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 13...

Page 14: Power Shield Overview
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. -

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 specific monitoring setup. 4B recommends an instant shutdown when maximum fill level or a plug condition has been detected. -
