1.2 Point level detector overview

Introduction

January 2017

The Rosemount 2140 and Rosemount 2140:SIS are point level detectors, and are designed to use the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency, and changes to this frequency are continuously monitored by electronics. The frequency of the vibrating fork sensor changes depending on the liquid medium in which it is immersed. The denser the liquid, the lower the frequency.

When the level detector is used as a low level alarm, the liquid medium in the tank or pipe drains down past the fork, causing a change of frequency that is detected by the electronics and it indicates a dry condition.

When the level detector is used as a used as a high level alarm or for overfill detection (Figure 1-1), the liquid medium rises in the tank or pipe, making contact with the fork which then causes the electronics to indicate a wet condition.

The wet and dry conditions can be transmitted digitally as a HART output using the analog output. See “Analog output type and operating modes” on

page 23 for details.

Major components of the point level detector are the fork and the electronics housing. The electronics housing contains the output electronics board, optional external configuration buttons, and terminal block.

An optional Local Operator Interface (“LOI”) uses a character display (Figure 1-2) to indicate the live output state, diagnostic messages, and menus. There are two rows of characters, with 8 on the upper row and 6 on the lower row. The LOI also comes with two integral buttons (“internal buttons”) for using the menu system.

When there is a detected change in process conditions, from wet-to-dry or dry-to-wet, the Sensor Output Delay variable can action a delay of up to 3600 seconds before the new state change is indicated. The default delay is one second.

Depending on the application, a suitable delay can prevent constant switching of the output state. If, for example, there are waves in a tank, then there may be splashes causing intermittently detected changes in process conditions. The sensor output delay ensures that the fork is dry or wet for a suitable period before switching.

The measured frequency of the fork, when immersed in process medium, can be affected by liquid density variations. As a result, the dry-to-wet and wet-to-dry switching points are different for all types and varieties of process medium (Figure 2-3 on page 18).

To overcome this, accurate switching points can be calculated by the Rosemount 2140 and Rosemount 2140:SIS after a suitable density band is selected for the process medium.

Media Density options the Rosemount 2140 and Rosemount 2140:SIS are:

 0.4 – 0.6 SG (for a 400 to 600 kg/m

 0.5 – 0.9 SG (for a 500 to 900 kg/m

2.8.8 Analog output range points

The analog output is driven by a device variable mapped to the Primary Variable (“PV”). Carefully read displayed warnings that appear before applying changes.

This section is for entering the range points for the PV to be output using the analog output.

The Lower Range Value (LRV) variable is the PV represented by 4 mA, and the Upper Range Value (URV) variable is the PV represented by 20 mA. This PV range can be a sub-set of the sensor limits defined by Upper PV Limit and Lower PV Limit variables (see Table 2-4

on page 28).

However, by default, the Output State is mapped to the PV. The range points for this are read-only and identical to the associated sensor limits (see “Sensor limits” on page 28).

If supported, Sensor Frequency or Scaled Variable can instead be re-mapped to the PV. The range points then automatically change from read-only to editable, allowing range points to be changed, but are subject to the sensor limits (see “Sensor limits” on page 28).

Reference Manual

00809-0100-4140, Rev AA

Optionally, use Scaled Variable Damping (page 28) to smooth out large steps in output current changes when the PV is a scaled variable.

2.8.9 Scaled Variable damping

Damping is an optional parameter for changing the response time of the level detector when the PV is mapped to the Scaled Variable. Increasing the damping value can smooth wide variations in the output caused by rapid input changes, but at the cost of decreasing response times.

Damping settings range from 0.0 to 60.0 seconds. An appropriate damping setting is a balance of the necessary response time, signal stability, and other requirements of the loop dynamics within your system.

2.10.2 Configuring alarm and saturation levels

Note

This function is available only when the Primary Variable (”PV”) is mapped to the Sensor Frequency or Scaled Variable device variables.

The Rosemount 2140 continuously performs self-diagnostic routines. When there is a device malfunction that is an alarm condition, the Analog Output current is driven to a configured alarm level (see tables) based on the HI or LO alarm switch position (see “Setting

the alarm switch” on page 46) and the ordered Alarm Level code.

In normal operation, the Analog Output current is driven in response to fork frequency changes. If the fork frequency goes outside sensor limits (see Table 2-4 on page 28), or if the output current would be beyond the saturation points (see tables), the current is limited to a saturation level based on the alarm switch position and the ordered Alarm Level code.

Failure mode alarm and saturation levels can be custom-configured using a Field Communicator, AMS Device Manager, or the Local Operator Interface (LOI). The following limitations exist for custom-configurable levels:

 Low alarm level must be less than the low saturation level.

 High alarm level must be higher than the high saturation level.

 Alarm and saturation levels must be separated by at least 0.1 mA.

Configuration

The configuration tool will provide an error message if the configuration rule is violated.

2.11 Configuring burst mode (optional)

Reference Manual

Fast keys

2, 2, 5 or 6, 3

Burst mode is compatible with the analog output signal. Due to the way that HART protocol features simultaneous digital and analog data transmission, the analog value can drive other equipment in the loop while the control system is receiving the digital information.

Burst mode applies only to the transmission of dynamic variables (PV, SV, TV, and QV), and does not affect the way other data is accessed. However, when activated, burst mode can slow down communication of non-dynamic variable data to the host by 50%.

Access to information other than dynamic variables is obtained through the normal poll/response method of HART communication. A Field Communicator, AMS Device Manager or the control system may request any of the information that is normally available while the level detector is in burst mode. Between each message sent by the level detector, a short pause allows the Field Communicator, AMS Device Manager or a control system to initiate a request.

2.13 Establishing multi-drop communications (optional)

Multi-dropping refers to the connection of several devices to a single communications transmission line. Communication between the host device and another device takes place digitally with the analog output of the level detector deactivated.

Multi-drop installation requires consideration of the update rate necessary from each device, the combination of different device types, and the length of the transmission line. Communication with devices can be accomplished with HART modems and a host implementing the HART protocol. Each device is identified by a unique address and responds to the commands defined in the HART protocol.

Field Communicators and AMS Device Manager can test, configure, and format a multi-dropped device the same way as a device in a standard point-to-point installation.

Figure 2-5 shows a typical multi-drop network.

Note

A multi-drop device in HART Revision 7 mode has a fixed analog output of 4 mA for all but one device. Only one device is allowed to have an active analog signal.

Configuration

January 2017

The Rosemount 2140 and Rosemount 2140:SIS are set to address zero (0) at the factory, which allows operation in the standard point-to-point manner with a 4–20 mA output signal.

To activate multi-drop communication, the level detector address must be changed to a number from 1 to 15 for HART Revision 5, or 1 to 63 for HART Revision 7. This change deactivates the 4–20 mA analog output, sending it to 4 mA. It also disables the failure mode alarm signal, which is controlled by the upscale/downscale switch position. Failure signals in multi-dropped devices are communicated through HART messages.

2.13.1 Communicating with a multi-dropped level detector

4.2 Cable selection

Wiring should be adequately rated and not be susceptible to mechanical damage. Electrical conduit is commonly used to protect wiring. The wiring to this device must maintain creepage(1) and clearance distances. Therefore, the conductors stripping length should be no greater than 6 mm and be free from stray strands.

Use shielded twisted pairs to get the best results. To ensure proper communications, use 24 AWG, to a maximum of 14 AWG, and do not exceed 5000 ft. (1500 m). Cable length is limited by the selection of monitoring resistance and wire gauge.

All power to the level detector is supplied over the signal wiring. Signal wiring does not need to be shielded, but use twisted pairs for best results. Do not run unshielded signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. For high EMI/RFI environments, shielded twisted pair cable should be used.

4.3 Cable gland/conduit

Reference Manual

00809-0100-4140, Rev AA

For explosion-proof/flameproof installations, only use cable glands/conduit entry devices certified as explosion-proof/flameproof. For ordinary location installations, use suitably rated cable glands to maintain the IP rating.

Un-used conduit entries must be sealed with a suitably rated blanking plug. See “Conduit entries” on page 103 for all other details.

4.4 Power supply

Terminals in the housing provide connections for signal wiring.

Rosemount 2140 and Rosemount 2140:SIS Level Detectors (“level detectors”) operate with the following power supplies:

 10.5 to 42.4 Vdc (10.5 to 30 Vdc in Intrinsically Safe installations).

For HART communication, a minimum loop resistance of 250 is required. Maximum loop resistance is determined by the voltage level of the external power supply (Figure 4-1).

Figure 4-1. Load Limitation

Maximum Loop Resistance = 43.5 * (External Power Supply Voltage – 10.5)

5.3 Analog output calibration

The analog output can be calibrated to match the user's measurement system. The Analog Output Trim (4-20mA Output Trim) will calibrate the loop at the 4 mA and 20 mA points.

5.3.1 Trimming the analog output

The Analog Output Trim commands allow you to adjust the level detector’s current output at the 4 and 20 mA points to match the plant standards. This trim is performed after the digital to analog conversion so only the 4-20mA analog signal will be affected. Figure 5-1 graphically shows the two ways the characterization curve is affected when an analog output trim is performed.

5.4 Performing tests and simulations

5.4.1 Device tests (partial proof test)

The Rosemount 2140 Level Detector (“level detector”) has device-testing functionality. Checks include:

 Critical RAM

 Program ROM

 Configuration storage non-volatile memory

 Device supply voltage

Operation and Maintenance

January 2017

The level detector can be configured to exercise the analog output to produce the currents representing the lower and upper range values (page 26) and alarm current (page 33).

If the level detector has the Extended Features Package (EFP) and the Scaled Variable or Sensor Frequency is assigned to the PV, the analogue output is also exercised from the low saturation level to the high saturation level (page 33).

By default, the device-testing sequence is not started at every power-up. It can be started by an operator through the LOI menu system i.e. TEST > DEVICE TEST or, when no LOI is not fitted, by using an optional single external push-button fitted to the top of the level detector (underneath the movable nameplate).

There are optional settings to configure:

 Duration of the whole testing sequence

(each phase takes an equal division of that total time).

 Enable/disable device-testing at start-up.

5.4.3 Verifying alarm level (optional)

If the electronics board, sensor module, or LOI display is repaired or replaced, verify the alarm current level before returning the level detector to service. This is useful in testing the reaction of the control system to a level detector in an alarm state. Thus ensuring the control system recognizes the alarm when activated.

To verify alarm values, run an analog loop test with the simulate alarm option selected (page 76). Ensure that the alarm switch is in the required high or low position (page 46).

Note

Before returning to service, verify the security switch is set to the correct position. Refer to “Setting the security switch” on page 43.

Operation and Maintenance

January 2017

5.4.4 Analog loop test (optional)

This test verifies the analog output of the level detector, the integrity of the loop, and the operations of any recorders or similar devices installed in the loop.

It is recommended that the 4-20 mA points, in addition to alarm levels, are verified when installing, repairing, or replacing a level detector.

The host system may provide a current measurement for the 4-20 mA HART output. If not, connect a reference meter (ammeter) to the level detector by either connecting the meter to the test terminals on the terminal block, or shunting level detector power through

the meter at some point in the loop.

5.5.5 Sensor state

Reference Manual

00809-0100-4140, Rev AA

Fast Keys

Sensor State indicates the present state of the vibrating fork sensor.

As the vibrating fork sensor becomes immersed in a process liquid, the vibration frequency decreases and the sensor state changes to a ‘wet state’ at a switching point.

When a process liquid falls away from the fork, the vibration frequency increases and the sensor state changes to a ‘dry state’ at a switching point.

If the fork sensor becomes damaged or develops a fault, the vibrating frequency moves outside normal operating limits and the sensor state changes to ‘too dry’, ‘too wet’, or ‘zero’. (See “Dry fork frequency and switching points” on page 85 for band limits).

5.5.7 Dry fork frequency and switching points

January 2017

Fast Keys

3, 4, 1, 3

The Dry Fork Frequency and switching points for Sensor Status transitions, can be viewed as values on a Field Communicator or graphically on the AMS Device Manager.

 Dry Fork Frequency (DFF)

This is the fork frequency recorded when the point level device is calibrated in dry conditions i.e. air. The frequency is typically 1260 to 1500 Hz.

The default dry fork frequency is established at the point of manufacture. However, it can be re-established by using the dry fork calibration procedure (page 87) when the level detector is installed in a working environment.

The dry fork frequency is also used by the Media Density (page 17) and Media Learn functions (page 19).

 Dry to Too Dry

Upper boundary for frequencies considered to be outside of the normal dry range. The “too dry” fault is indicated for the enhanced operating mode only.

 Dry to Indeterminate

Lower boundary for frequencies considered to be outside of the normal dry range.

 Wet to Indeterminate

Upper boundary for frequencies considered to be outside of the normal wet range.

 Wet to Too Wet

Lower boundary for frequencies considered to be outside of the normal wet range. The “too wet” fault is indicated for the enhanced operating mode only.

 Zero

The cut-off boundary, below which the sensor frequency is considered to be 0 Hz. The “zero” fault is indicated for the enhanced operating mode only.

Note

In normal mode, a 0 Hz sensor frequency represents a wet condition (not a fault). When operating in enhanced mode, a 0 Hz sensor frequency represents a fault condition.

The following counters are available:

 Sensor Wet Count

The count increments each time the Sensor State changes from dry to wet. This counter can be reset by entering a new value using Reset/Preset Wet Count.

 Calibration Count

The Rosemount 2140 and Rosemount 2140:SIS are calibrated under reference conditions at the factory. In special circumstances, it may be re-calibrated in the field and this increments the count.

 Fault Count

The count increments each time there is a fault (see “Sensor status” on page 83). This counter can be reset to zero using Reset Fault Count.

The following timers are available when in HART 7 mode:

 Time Since Output Change

The time elapsed since the Output State last changed.

 Total Time Dry

A totalized time for how long the Sensor State has been indicating ‘dry’. This timer can be reset to zero.

 Total Time Wet

A totalized time for how long the Sensor State has been indicating ‘wet’. This timer can be reset to zero.

5.6 Dry fork calibration

5.6.1 Site calibration of dry fork sensor

Operation and Maintenance

January 2017

Fast Keys

This command starts the on-site calibration of the fork sensor in dry process conditions. It should only be performed by authorized persons.

A comparison is made between the live fork sensor frequency measured in dry process conditions and original factory-set Dry Fork Frequency value (page 85).

If the difference is greater than Allowable Change In Dry Fork Frequency (page 21), the re-calibration is rejected. Check the fork for damage, corrosion, or coating, and clean the fork if necessary before re-trying.

When the calibration is successful, Dry Fork Frequency is set to the new dry frequency. See also “Dry fork frequency and switching points” on page 85 for related information.

5.6.4 Configuring Power Advisory Diagnostic

Introduction

The optional Power Advisory diagnostic provides a means to detect issues that may jeopardize the integrity of the electrical loop. Some examples are: water entering the wiring compartment and making contact with the terminals, an unstable power supply nearing end of life, or heavy corrosion on the terminals.

This technology is based on the premise that, after a Rosemount 2140 or 2140:SIS (“level detector”) is installed and powered up, the electrical loop has a baseline characteristic that reflects the proper installation. If the level detector terminal voltage deviates from the
