The user is responsible for all changes and repairs made to the device by the user or the user’s agent. • All new components are to be provided by Siemens Milltronics Process Instruments Inc. • Restrict repair to faulty components only.
Introduction Notes: • This product is intended for use in industrial areas. Operation of this equipment in a residential area may cause interference to several frequency based communications. • The Probe is to be used only in the manner outlined in this instruction manual. The Probe is an ultrasonic level monitor combining sensor and electronics in a single package.
Mounting Mount The Probe so that the face of the sensor is at least 25 cm above the highest Note: anticipated level. Threaded hinged lid 7 mm The Probe is available in three thread types: 84 mm (0.3") (3.3") max. 2"...

Operation Start Up program mode alphanumeric • With The Probe correctly installed (or ’20’ key aimed at a wall 0.25 to 5m [US-100-1], 0,25 to 8m [US-100-3]away), apply power. units • The Probe starts up displaying the ’4’ key following:...
Calibration The calibration of the mA output may be done such that its span will be either proportional or inversely proportional to the material level. The 4 and 20 mA levels may be calibrated in Note: any order. proportional span inversely proportional span high level = 20 mA high level = 4 mA...
Adjustments There are several operating adjustments that can be made to The Probe. • Press the "4" and "20" keys simultaneously until the desired adjustment is obtained. A viewing sequence of the stored value is automatically initiated. • During this time, press either the "4" or "20" key to change the value. After viewing or changing, operation automatically reverts to the Run mode (6 sec).
Blanking The Probe Blanking is used to ignore the zone in front of the transducer where false echoes are at a level that blanking interfere with the processing of the true echo. It is measured outward from the sensor face. The minimum recommended blanking value is 0.25 m (0.82 ft) but can be increased in order to extend the blanking.

• To change the speed of response, obtain the `SP' display. • Scroll forward through the options (1-2-3) by pressing the "20" key. Scroll backward through the options (3-2-1) by pressing the "4" key. • When the desired option is displayed, stop pressing the key. The display will automatically return to the Run mode (6 sec).
• To change the fail-safe default obtain the `FLS' display. • Scroll forward through the options (1-2-3) by pressing the "20" key. Scroll backward through the options (3-2-1) by pressing the "4" key. • When the desired option is displayed, stop pressing the key. The display will automatically return to the Run mode (6 sec).
Supplement Loading vs. Supply Voltage Troubleshooting The echo is not reliable and The Probe is waiting for a valid echo before updating the measurement. Probable causes are: • material or object in contact with sensor face • The Probe is too close to the fill point •...
