  • Page 4: Introduction

    High accuracy and no maintenance are two of the most common reasons for choosing this technology. With optional ratings to 800°F (427°C) and 3000 PSI (207 bar), K-TEK's Magnetostrictive Level Transmitters are suitable for almost any application. HART, Honeywell DE, and Foundation Fieldbus Protocol options make our AT100‟s easy to connect digitally to most control systems.

  • Page 5: Storage Information

    4.0 TRANSMITTER CALIBRATION AND SETUP 4.10.4 Setting Up Strapping Table Points Under the CAL menu: 1) Scroll to VOL TABL, then press SELECT. A) In manual mode, set the measured value for each Input Point and set the corresponding Output Point to the desired volume value.

  • Page 14: Alarm Delay

    4.0 TRANSMITTER CALIBRATION AND SETUP 4.11 Alarm Delay The AT100 transmitter is designed to send the current output into a Fail Safe mode when the transmitter does not detect a return signal from the sensor tube or the transmitter experiences a diagnostic failure. In certain installations (such as high vibration areas) the transmitter may experience sporadic interruptions in the return signal which are not an indication of sensor tube failure.

  • Page 15: Communication Options

    5.0 COMMUNICATION OPTIONS 5.1 HART Protocol Interface Option The K-TEK transmitter can be ordered with the HART Protocol Option, which is installed at the factory as a part of the electronic module assembly. When fitted with the HART Protocol Option, it will be possible to communicate with the transmitter using a Rosemount 268, 275, or 375 communicator utilizing slave mode.

  • Page 17: Field Wiring

    5.0 COMMUNICATION OPTIONS 5.3.3 Field Wiring All power to the transmitter is supplied over the signal wiring. Signal wiring should be a shielded, twisted pair for best results. Do not run unshielded signal wiring in conduit or open trays with power wiring or near heavy electrical equipment.

  • Page 18: Pid Blocks

    5.0 COMMUNICATION OPTIONS 5.3.8 PID Blocks The AT transmitter is equipped with 5 PID (Proportional, Integral, Derivative) Blocks. These blocks can be used to implement control algorithms within the transmitter. The output of the PID Block can be linked to the AO (Analog Output ) Block of another instrument like a valve or to the input of another PID Block.

  • Page 19: Safety, Maintenance, & Troubleshooting

    If a transmitter fails an inspection or assistance is required for inspection or troubleshooting, contact the Service Department at K-TEK Corporation via e-mail at service@ktekcorp.com. The Service Department will answer questions, provide additional assistance, and issue Return Authorization Numbers for equipment in need of repair.

  • Page 20: Suggested Proof Test

    Note: K-TEK floats are designed for different specific gravity ranges. The float may or may not float in the water. It may be necessary to hold the float under the water to perform this test.

  • Page 21: Sensor Inspection

    6.0 SAFETY, MAINTENANCE, AND TROUBLESHOOTING 6.4.2 Sensor Inspection The sensor of the AT100 consists of a metal tube containing several wires. The sensor tube will measure the float location properly if the tube is straight and the float can travel freely up and down its length. Perform a visual inspection on the sensor tube to make sure it is straight, free from pits or gouges, and does not show excessive wear patterns.

This troubleshooting section only covers problems specific to Foundation Fieldbus setup and communications. Troubleshooting of the level indication from the Transducer Block may require the use of the 4- 20mA, HART troubleshooting section.

  • Page 25: Verify Proper Power Up Of The Transmitter

    6.0 SAFETY, MAINTENANCE, AND TROUBLESHOOTING During normal operation, it is not necessary to perform maintenance on the AT100 transmitter. Routine calibration of the transmitter is not necessary. The AT100 contains an EPROM which will store calibration in case of an outage or electronics replacement. 6.7 Verify Proper Power-up of the Transmitter Use a mA meter to measure the output current.

  • Page 26: Threshold Adjustment

    6.0 SAFETY, MAINTENANCE, AND TROUBLESHOOTING 6.9 Threshold Adjustment If the output occasionally jumps to an alarm condition (**** on display), this can be an indication of a loss of signal or a transmitter threshold voltage not set properly. The adjustment can be done as follows Note: It is preferable to make this adjustment with the float located towards the end of the sensing tube, away from the transmitter housing, but within the normal measuring range.

  • Page 27: Threshold Adjustment Using An Oscilloscope

    6.0 SAFETY, MAINTENANCE, AND TROUBLESHOOTING 6.12 Threshold Adjustment Using an Oscilloscope Principle of Operation: The main module in the AT housing performs 10 measurement cycles per second. 1.
