Operating Principles

Capacitance1 measurement operates by forming a variable capacitor resulting from the installation of a measurement electrode in a vessel or silo. The environment (for example, the tank wall) acts as a reference electrode. Whatever material is sandwiched between the two electrodes forms the dielectric. This will be composed of the vessel contents (air, vapor, liquid, solid, or a combination) and, if the measurement electrode is insulated, the insulating layer (PFA, for example). The dielectric gives a capacitance value.

Capacitance is affected by the surface area of the electrodes, the separation distance between the electrodes, and the dielectric constant of the vessel contents. The relative dielectric constant is the measure of a material’s ability to store energy. The relative dielectric constant of air (vacuum) is 1: all other materials have a higher value.

The capacitance when the probe is uncovered (capacitance in air) will be different from the capacitance when the probe is covered (for example, capacitance in water). If the product is two immiscible liquids with different relative dielectric constants, (for example, oil and water) the capacitance will change at the interface between the two liquids.

Pointek CLS500 variable frequency oscillator

The Pointek CLS500 probe is equipped with a variable frequency oscillator which responds to the capacitance. A change in capacitance is registered as a change in frequency. This technology provides high resolution and accuracy. The variable frequency maintains a constant relationship to the reading.

For definitions relating to capacitance, see the glossary, page 103.

Operation & Application

Page 16

Capacitance measurement in a cylindrical metal tank

K  L

Log D d

--------------------------

In a cylindrical tank, the initial capacitance in air is calculated by factoring in the length of the probe, diameter of the probe, diameter of the tank, and the relative dielectric constant of air.

The formula

is:

where: C = capacitance

K = constant

 = dielectric constant

L = active measurement length D = diameter of tank d = probe diameter

When the material inside the vessel changes, the relative dielectric constant changes, which results in a capacitance change.

The transmitter measures the capacitance of the measurement electrode relative to the environment (reference electrode). Any material that covers the probe will cause an increase in capacitance relative to an uncovered probe surrounded by air. As the product level rises the capacitance will increase. The minimum change in capacitance required to detect a change

in the medium is 1pF (within a range of 330 pF).

The Pointek CLS500 electrode

The Pointek CLS500 electrode, comprising a measurement section and an active shield section, is the primary sensor of the system. It supplies the electrical capacitance value of the measurement section relative to the environment.

Operation & Application

The Pointek CLS500 patented Active-Shield Technology electrically isolates the measurement section and prevents any non-measurement capacitance from interfering with the measurement. (Capacitance changes could result from uncontrolled variations occurring in the connection cable, process connection, and non-active parts of the probe.) This gives a better ratio of initial capacitance to total capacitance, resulting in higher accuracy

This formula applies to a centrally mounted probe: for a probe mounted off-centre, the formula must be adjusted.

From absence to presence, or vice versa.

The measurement is further protected from interference by a buffer, which applies the frequency signal from the measurement section to the active shield section. This effectively eliminates any electrical potential difference between the shield and the measurement section and prevents additional changes in capacitance occurring.

The relative lengths of the measurement section and active shield section can be specified to suit a particular application. If the measured range will be short relative to the total length of the electrode, specify a short measurement section. This increases the

7ML19985GG03 Pointek CLS500 – INSTRUCTION MANUAL Page 11

Operation & Application

Page 18

achievable resolution of the measurement, since any change in level will be greater relative to the length of the measurement section.

The entire Pointek CLS500 transmitter is potted in epoxy resin as part of the intrinsic safety protection. The potting also protects the electronics against mechanical vibration and moisture influences.

The transmitter is connected to the electrode by a mini coaxial cable, and grounded to a connection point inside the enclosure. The external ground lug on the enclosure provides a means of connecting the instrument system ground to a grounded tank. (For more detailed information on grounding requirements, please see Grounding Examples, page 35.)

–12

The measuring range of Pointek CLS500 is 0 to 330 pF (1.0 pF  10

F).

Note: For safety purposes, and to ensure reliable measurement signals, the external

ground lug provided on the Pointek CLS500 enclosure must be firmly connected by an adequate cable to the grounded vessel.

Application: Pointek CLS500

Pointek CLS500 has two modes of operation:

• FailSafe High or Low mode (FSH or FSL)

• Free Programming Mode (FPM)

Pointek CLS500 is most often used in FailSafe High/Low mode. This links the settings for triggering an alarm and a fault signal, so that you do not have to set each parameter individually: in effect, it acts as a shortcut.

Free Programming Mode allows each parameter to be set independently. In this mode, the continuous mA signal is available. FPM mode is less often employed with Pointek CLS 500.

Product or Interface detection

The capacitance of the electrode system is dependent on the dielectric constant of the product surrounding the probe. By comparing the capacitances resulting from different products with different dielectric constants, it is possible to determine what product is surrounding the probe.

For products that mix together:

Contamination of one product by another can be measured:

100% product A 4 mA

Operation & Application

For products that do not mix:

The interface between two products can be detected by the change in capacitance from one product to the other.

Page 12 Pointek CLS500 – INSTRUCTION MANUAL 7ML19985GG03

100% product B 20 mA Values in between 4 and 20 mA represent the ratio of the two products

Continuous measurement is only available in Free Programming Mode.

Page 19

Level Detection

The continuous 4-20 or 20-4 mA signal is proportional to the surface level of the product, with an accuracy of 0.1% of the actual measurement (for example, 1mm/m). Because the loop current is in two-state mode for fault signalling, the continuous mA signal is not available in FSH/FSL mode.

Depending on the requirements of the application, Lower Range Value (LRV - 0%) can be set to 20 mA and Upper Range Value (URV - 100%) set to 4 mA, or the reverse. The measurement takes place anywhere within that range. The LCD displays the value as mA, or pF, depending on the setting for the transmitter variable (TV). If you are using HART, you have the option to define the units (for example, meters).

2-state Switch

The mA output can be used as a 2-state switch set to either 4 or 20 mA. It can be set to go to 4 mA if the probe is covered and 20 mA if the probe is uncovered, or the reverse.

Fault Signalling

Pointek CLS500 has three signal output options:

• via the loop-current

• via the solid-state switch

• via HART

Via the loop current

When using the mA signal, Pointek CLS500 operates according to NAMUR standards1 for fault signalling. The fault/failure signal can be triggered by a failure in the measuring system, such as:

• a checksum error

• a loss of signal caused by a defect in the module

• a short circuit in the sensor

• a process failure if the level exceeds the limit settings and if the unit is programmed to detect this

Operation & Application

You can set the Upper and Lower Sensor Limits (menus 0B and 0C) outside the Upper and Lower Range Value settings. In this case, if the process value is outside its nominal range (the span between LRV and URV), but still not at a fault/failure level, the continuous mA output will saturate to 3.8 mA or 20.5 mA. If the process value is outside the Upper or Lower Sensor Limits, this will be registered as a fault/failure.

See

NAMUR recommendation NE 43

on page 100 for more details.

Page 20

If you select FailSafe Mode at menu 1E, menus 08 and 18 are linked1, and either FailSafe High or FailSafe Low can be selected. The factory setting for menu 1E is FailSafe High (FSH). Menu 08 controls the mA output, and menu 18 controls the solid-state output.

In FailSafe High mode, (FSH):

• High Signal current (20 mA) and solid-state switch closed in normal conditions when probe is uncovered.

• Low Signal current (3.6 mA) and solid-state switch open when fault/error occurs.

In FailSafe Low mode, (FSL):

• Low Signal current (4 mA) and solid-state switch open in normal conditions when probe is uncovered.

• High Signal current (22mA) and solid-state switch closed when fault/error occurs.

If you do not use communications to receive status information, we recommend utilizing analog fault signalling (menu 08) in order to be warned if a fault or failure occurs.

Via the solid-state output

The solid-state switch can be wired up to an external relay, to provide a second level of protection. It can then be used to activate a failure alarm, or a level switch. (See page 96 for details of a typical application using the analog signal in 2-state mode to provide a high alarm, and using the solid-state switch to provide a high-high alarm.)

Via HART

See page 84 for by a response code. It is then up to the Host to decide what to do in the case of a fault situation. The Host may decide to issue Command 48, which returns more detailed information.

HART Response Code Information

. Each HART message is accompanied

Adjusting alarm settings:

The adjustable hysteresis and time delay settings allow you to adjust the unit for applications with a lot of surface movement.

With a moving surface that fluctuates between 79% and 80%, if the hysteresis is set so that 80 is on and 79 is off, the alarm will constantly alternate between on and off. To prevent this, either set a time delay, or adjust the hysteresis:

• Set the time delay to10 seconds, for example: the alarm will be on only after the surface has been at 80% for at least 10 seconds.

Operation & Application

Page 14 Pointek CLS500 – INSTRUCTION MANUAL 7ML19985GG03

• Reset the hysteresis: for example, set the Upper Threshold setting for 80 and the Lower Threshold setting for 70. The unit will ignore smaller surface fluctuations.

FailSafe Mode at menu 1E provides a shortcut, by contrast with Free Programming Mode where all menu items are completely independent. You can make the same selections in FPM, but you need to set each menu item individually.

portion

probe seal (inactive)

The probe (electrode) comprises a measurement section and an active shield section. This electrode connects to the capacitance detector portion of the two-wire loop powered electronic transmitter. The transmitter module is mounted in a powder-coated aluminum enclosure which provides reliable operation in environments with dust, moisture, and high-frequency interference.

Pointek CLS500 Electrode (Probe) Characteristics

Apply to all general connection configurations:

• The standard Pointek CLS500 insulated electrode is designed for use in both conducting and non-conducting liquid applications.

• Most electrodes consist of an active shield portion and a measurement portion, which combine to form the complete electrode. (This is not the case for electrodes with ceramic/enamel insulation.)

• The sum of the active shield length and the measurement length is the total insertion length.

• The active shield design provides continuous immunity from changes in conditions at the top of the vessel where levels of vapors, dust, and condensation may be constantly changing.

• The design of the active shield isolates the starting capacitance of the electrode from the effects of changes in capacitance due to temperature and pressure fluctuations that could cause small changes in the seal geometry.

• The end seal is formed as an integral part of the electrode insulation, giving smooth and uniform characteristics (tested to 55 kV).

• Standard single cone seal

Process Connections

Appendix E: Pointek

The standard threaded process connection with PFA insulated electrode, including the active shield, provides good results in all measurement situations within the temperature, pressure, and corrosive capabilities of the materials and seals. This remains true over a wide range of dielectric constants in both non-conducting and conducting materials.

Any standard process connection is available with Pointek CLS500, and special versions can be fabricated to match the mounting and application requirements. A wide range of threaded and flanged fittings is available. (Contact your local Siemens Milltronics representative, or check our website at www. siemens.com/processautomation

Seal Types

The basic internal seal for Pointek CLS500 has a conical-shaped, preloaded pressure/leak resistant construction. Up to three levels of seal protection are implemented depending on the integrity requirements of the application. A single or double cone internal seal forms one or two barriers against leaking, and a third flange face gasket is also available in the D and DD seal construction. The flange face seal also provides a design with no metal wetted parts if required.

Interconnection: Pointek CLS500

Wiring

WARNING:

• The DC input terminals shall be supplied from a source providing electrical isolation between the input and output, in order to meet the applicable safety requirements of IEC 61010-1.

• Observe the specifications of the examination certificate valid in your country.

• Observe the laws and regulations valid in your country for electrical installations in potentially explosive atmospheres.

• Ensure that the available power supply complies with the power supply

Interconnection

specified on the product nameplate and specified in the examination certificate valid in your country.

• Dust-proof protection caps in the cable inlets must be replaced by suitable screw-type glands or dummy plugs, which are appropriately certified for transmitters with explosion-proof protection.

• The lid must not be opened in wet locations while the unit is powered. (A wet location is a location where water or another conductive fluid may be present and is likely to increase the risk of electric shock.)

Supply

Notes:

• The transmitter is powered by the current loop and needs at least 9.5-13 Volt on the terminals: 9.5 V at 22 mA or 12 V at 3.6 mA.

• The maximum supply is 33 Volt. If the voltage is higher the device will shut down.

• The loop-circuit will withstand voltages up to 250 Vac/Vdc without any damage.

Pointek CLS500 uses a switched power supply circuit, which makes the most efficient use of the available power present on the terminals. If the signal current is low (4mA) the terminal voltage will be high, and if the signal current is high (20 mA) the terminal voltage may be low, due to all the resistive elements in the loop, such as the barrier and sense resistor.

Examples:

• With a 250 Ohm sensing resistor, no barrier and negligible cable resistance, the overall supply voltage should be at least 15.0 V.

• With a 250 Ohm sensing resistor, a barrier of 280 Ohm, and 20 Ohm cable resistance (500 m), the total resistance is 550 Ohm, so the overall supply voltage should be at least 20.5 V.

• For a multi-drop application, where the measuring supply is fixed to 4 mA, the voltage on the terminals of the Pointek CLS500 should be at least 12 V.

The loop circuit is completely isolated from the measurement circuit. It is designed so that the internal capacitance and inductance on the terminals are isolated, and are not a factor in safety calculations.

Interconnection

Cable

Notes:

• To maintain reliable transfer of the HART modem signals, the RC1 time constant of the connections should be less than 65 μSec.

• For output signals (from the Pointek CLS500), only the cable and barrier resistance are relevant. For input signals the measurement resistance is also relevant.

• Use twisted pair cable, screened as a pair.

RC = Resistance * Capacitance

If you use a common screen over a cable containing multiple twisted pairs, do not use other pairs for signals that could interfere with HART signals.

Selecting the correct instrumentation cable

• you need to know the cable length and the measurement resistance

• select a cable that will give you a capacitance time constant of less than 65 μSec

Multi-drop applications: maximum cable length

In a multi-drop application, the total capacitance of all the devices must be calculated. With three devices, at 3 x 68 nF, the allowable cable length will be considerably limited.

Notes:

• If the device is part of a multi-drop setup, Pointek CLS500 sets the current to 4 mA, which inhibits analog signalling, including fault signalling.

• Multi-drop is a HART mode where devices are set to a fixed current, and the device is interrogated periodically. The maximum number of devices on one loop is 15, one of which can be an analog mode device.

Notes:

• Since the measurement occurs between the Measurement and Ground connections, it is important to have good, low-resistance, reliable connections in this circuit.

• Use a ground connection wire with a sufficiently large diameter relative to its length, and not less than 1mm

• The Pointek CLS500 measurement circuit is completely isolated from the loop circuitry: this allows either line of the loop circuit to be grounded if requirements for Ex safety are followed and if the power supply voltage is less than 33 Vdc.

Grounding is important for two reasons:

1. To prevent interference to the signal: system grounding

2. For safety purposes: safety grounding

Several common applications are illustrated. They are separated into two groups: the first group illustrates System Grounding and the second illustrates Safety Grounding.

System Grounding (referencing)

For the measuring system to function correctly, the reference electrode must be properly grounded. Make sure that there is a reliable connection from the instrument housing to the reference electrode (usually the wall of a metal tank involving system grounding include:

• metal tanks

• metal tanks, cathodically protected

• non-conductive tanks

). Some common applications

Interconnection

If the grounding reference is not the tank wall, connect the ground lug to another object that has conductive characteristics and that is reliably grounded.

7ML19985GG03 Pointek CLS500 – INSTRUCTION MANUAL Page 35

Page 42

Interconnection

Cathodically Protected Metal Ta nk s

Cathodically protected metal tanks are never directly grounded. However, the impedance of the supply source is so low that it will not cause any problems. The shielding of the loop cable should be grounded at one end only (the tank end) to avoid short-circuiting the cathode protection voltage.

The ground lug on Pointek CLS 500 can be connected to the tank as shown.

(See page 33 for further grounding details.)

metal

ground lug

Non-Conductive Tanks

Non-metallic tanks always require a proper grounded conductive medium: connect the ground lug on the Pointek CLS 500 to earth ground.

With non-conductive contents:

• there must be a solid connection from the instrument to a grounded object in the environment (a metal tank wall, or the metal frame of a non-conductive tank).

With conductive contents:

• the vessel contents must be grounded, for example by being in contact with a grounded metal pipe.

The safety grounding requirements are determined by the application and the connected instruments. The Pointek CLS500 transmitter does not have any special requirements due to the galvanic separation between the measurement section and the loop section.

Depending on the DCS characteristics, there are three possible grounding options:

• If the DCS measures the current through the loop compared to a common zero Volt point, do not ground the negative side of the current loop because measurement inputs can be short-circuited.

• If the DCS measures the current in the positive wire or connector, the negative side of the current loop can be grounded.

• If the DCS has galvanically separated inputs for each measurement channel the grounding method can be chosen as required.

In hazardous applications a Stahl-type barrier is required, and it is typically mounted on a DIN rail inside a customer-supplied enclosure located in the non-hazardous area.

If no specific Ex conditions apply, Pointek CLS500 can be directly connected to the DCS. The supply voltage, however, should remain within the limits set by the Pointek CLS500. Connecting a Pointek CLS500 to a DCS does not influence that equipment. One of the connection cables can be grounded if desired.

Pointek CLS500 is equipped with HART1 communication protocol2so that settings and values can be obtained and altered locally3 or remotely.

Interconnection

Diagnostics

The internal diagnostic functions continuously monitor the operation of the transmitter. An error signal is generated if a failure or irregularity occurs.

Pointek CLS500 sends the signal current according to the NAMUR NE 43 recommendation. During normal operation the current remains within the range from 3.8 to 20.5 mA. If the process exceeds its normal limits but is not in a fault or failure situation, the signal current will be outside the measurement range (4 to 20 mA) but will be limited to either 3.8 or 20.5 mA.

If a fault or a failure is detected, the signal current is set to either 3.6 mA or 22 mA, depending on the settings you have chosen. This feature may be disabled by the user.

Depending on the system design, the power supply may be separate from the PLC, or it may be part of the PLC.

A 250 Ohm resistor is required only when the PLC is connected to a HART modem or a HART communicator.

The HART communicator and a PCL/laptop computer cannot both be connected to the 4-20 mA loop simultaneously.

using the push-button feature and the appropriate menu selection. In most cases you can do a one-point calibration

by using the push-buttons to input the actual level in %.

The total isolation between the measurement circuit and the current- loop circuit provides immunity during the use of cathode protected measuring tanks. Connection to PLC equipment is possible without any difficulty.

The Upper Sensor Limit (USL) and Lower Sensor Limit (LSL) are set to 330 and 1 pF respectively, and the following conditions apply:

• The Upper Range Value (URV) and Lower Range Value (LRV) should be within

the USL to LSL range, but can be set anywhere within that range.

• An interruption of the measuring connection will be detected: a loose or

interrupted connection results in up to 0.5 pF capacitance, which is below the adjusted LSL and thus signals a FAULT condition.

Applications for Solid-State Output

The solid-state output is a polarity independent switch output. The solid-state switch has two possible functions:

• In normal process conditions, it can be activated/deactivated when the product

level reaches the upper/lower threshold settings (set in menus 15 and 16).

• When a fault or failure is detected in the process or in the measurement circuit,

it can signal a fault (set in menu 18).

Interconnection

The solid-state switch has its own parameter set: menu items 13 to 18, (see

Menu Levels Mode)

and the solid-state switch, to provide alarm and fault signalling in the event of an error/ failure

In menu 0E and menu 0F, you set the Upper and Lower Range Values (URV and LRV) for relay operation. Within that range, the solid-state switch has independent settings for Upper and Lower Threshold, (menus 13 and 14) and the corresponding delays (menus 15 and 16).

on page 51.

The Two

Page 46

When the solid-state switch is to be operated as a fault/failure output (for example, for a separate shutdown system) we recommend disabling the operation for signal output (select Free Programming Mode at menu 1E, and Disabled Mode in menu 17 on page 77). When the solid-state switch control is disabled at menu 17, the threshold delay settings are unavailable.

See page 96 for details of a typical application using Pointek CLS500 to provide a high alarm via the current loop, and a high-high alarm using the solid-state switch.

Notes:

• The solid-state output should only be used in circuits where the current is limited by a proper load.

• Due to the limited switching capabilities of the solid-state switch component, an auxiliary relay must be applied when switching high-current/high-voltage apparatus.

Switch Protection Diode

Interconnection

WARNING: When the solid state switch is activating an external relay, protection diodes must be connected in the correct polarity across the relay coil to prevent possible switch/relay damage resulting from inductive spikes generated by the relay coil.

Factory Settings

Pointek CLS500 has a number of default factory settings. If the required settings for the application are known, the settings can be modified during final testing.

Note: To restore factory settings, use menu item 12 (see

The rotary switch

The rotary switch gives you access first to the menu level and then to the menu item1.

The rotary switch has a small slot where the current position can be read. The positions are read clockwise, and in increasing order: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. The position wraps from F to 0.

The switch can be moved in either direction. When it is turned to a new position, the LCD displays the new menu selection for one second, followed by the data for that position.

Certain menu selections return more than one piece of information per item: in that case the display alternates between the two values, for example, PV Value / Fault status.

The push-buttons

The push-buttons allow you to change the value of a menu item. Use the RED (+) button to adjust a value up; the BLUE (–) button to adjust a value down; or press both simultaneously for special applications. For a table showing the combinations of rotary switch positions and button presses used to carry out different functions, see page 48.

User Interface

Access to a menu item:

Notes:

• For a detailed description of each menu item, see starting page 61: the functions of the menu items are illustrated in the application example on page 96.

• Change over from Menu LEVEL 0 to Menu LEVEL 1 is only possible at position 0, from menu item 00 to 10 or vice-versa. (See page 50 for detailed instructions.)

1. First select Menu LEVEL 0 or Menu LEVEL 1.

2. Turn the rotary switch to the number of the desired item.

For a chart showing the rotary switch positions and related functions when FailSafe High or FailSafe Low mode is selected, see page 48. (If Free Programming Mode is selected, see on page 111.)

Adjusting the value

Notes:

• The push buttons are preset with a delay called the debounce time.

• Keeping one or both buttons pressed continuously will trigger an auto-repeat in some menus.

1. Select a menu item.

2. Press the RED (+) or BLUE (–) push button to adjust the value up or down: acceptance is indicated when the left-most colon on the LCD appears. (You have to press longer than the debounce time to have the action accepted; the debounce time varies according to the menu item selected.)

Transmitter Variables

• Transmitter Variable 0 (TV0) is the capacitance as measured by the device.

• Transmitter Variable 1 (TV1) is a computed variable: the dynamic value is a computed derivative from the range settings for TV0.

Start-up: Pointek CLS500

Capacitance measurement systems require the instrument to be adjusted for a particular application. Two methods of adjustment are available:

• push-button (for instructions, see page 51)

• HART (for instructions, see page 54)

Quick Start

We strongly recommend you read the full manual to use your Pointek CLS500 to its fullest potential. However, if you can bring the product to the 0% and 100% point level, you can use the Quick Start sequence on page 47 to set up the instrument and get started. (For most applications, 0% is an uncovered probe, and 100% is a covered probe.)

Pointek CLS500 is most often used in Failsafe High or Failsafe Low mode (FSH or FSL), which sets the loop current to 4 or 20 mA 2-state mode.

Startup

Quick Start Sequence

For overfill protection: Install the device with the probe uncovered.

1a 2a Power it up. 3a Set the first operating point for the switch, LRV at menu 0E

Set value for 0% (LRV): units must be pF (Menu 01 must read Pv = 0); probe must be uncovered.

a Turn the rotary switch to E (Empty).

b Press both buttons and hold for about 1 second: the 0% point is now set.

(In FailSafe mode, the LCD blinks to indicate the probe is uncovered.)

4a Set the second switch point: use menu 0D to generate URV

Set value for 100% (URV): probe must be uncovered.

a Turn the rotary switch to D (Delta Range).

b Press and hold both buttons for about 1 second: this takes the minimum span and adds it

to the value for LRV to generate the value for URV. (This guarantees the device will switch if the product approaches or touches the probe.)

c If the device is over-sensitive, use the RED (+) button to increase the Delta Range

setting. (This will increase the value for URV and increase the span between LRV and URV.)

(The LCD will stop blinking when the probe is covered.)

For dry-run (underfill) protection 1b Install the device with the probe covered. 2b Power it up. 3b Set the first operating point for the switch, URV at menu 0F

Set value for 100% (URV): units must be pF (Menu 01 must read Pv = 0); probe must be

covered.

a Turn the rotary switch to F (Full).

b Press both buttons and hold for about 1 second: the100% point is now set.

(The LCD stops blinking when the probe is covered.)

4b Set the second switch point: use menu 0D to generate LRV

Set value for 0% (URV): probe must be covered.

a Turn the rotary switch to D (Delta Range).

b Press both buttons and hold for about 1 second: this takes the minimum span and

subtracts it from the value for URV to generate the value for LRV.

c For products that are conductive and viscous, use the RED (+) button to increase the

Delta Range setting. (This will decrease the value for LRV and increase the span between URV and LRV). (The LCD will blink if the probe is uncovered.)

• If the difference in the capacitance value between the 4 mA point and the 20 mA point is smaller than the minimum span value (1 pF), the new value will not be accepted.

If the stepsize is too large, see page 53 for details on adjusting the stepsize.

Changing stepsize value: menu 09

If the steps are too big or too small when you are adjusting values, you need to change the stepsize (menu 09) to a different value.

The factory setting is 1: the LCD displays U: 1.0

a. Set rotary switch to 09 b. Press BLUE (–) button to reduce stepsize: values range from 0.01 to 1,000,

or: press RED (+) button to increase stepsize.

Example:

LCD displays 28.00 (m) Known height = 17 m Decrease needed is 11, but setting for stepsize is 10: menu 09 set to U: 10. Press BLUE (–) button to reduce stepsize to 1: LCD displays U: 1.0.

Return to OF, and decrease value to 17.00 (m).

Setup using HART

You can set up Pointek CLS500 transmitter using HART, with a HART communicator; a laptop running Simatic PDM, or with the Host system (DCS). The local circumstances determine the easiest method. If you can bring the product to the 0% and 100% point level, setup is simple. (Either the probe state is uncovered at 0%, and covered at 100%, or the reverse.)

Notes:

• Use the arrow keys, up, down, forward, and back to navigate within the menus.

• Use the back arrow to return to previous screens.

Maintenance

Test Function

Auto Self-testing

Pointek CLS500 continuously performs a variety of tests to verify that the device is functioning correctly. These include a test where a known capacitor is applied to the input of the device. The internal results must match the known capacitance value. If a deviation is detected the Fault/Failure can be flagged with a pre-set loop-current (user configurable) and as a status in each HART message.

Manual testing

In order to test the proper processing of signals in PLC/DCS equipment, Pointek CLS500 allows you to invert the output signal status. In Menu 11, when both buttons are pressed simultaneously, the signal outputs switch to their opposite state. When the buttons are released, the outputs revert to the initial state.

Note: If a Fault or Failure is present, its signal will take precedence over the test

function.

If no Fault/Failure is present and no buttons are pressed, the display for menu 11 alternates between two test patterns which together illuminate all the segments of the display. If the loop-current control is in analog mode the loop current will hold the last value, during this test.

Inspections

Under normal circumstances, the Pointek CLS500 transmitter requires no maintenance. However, we recommend that you schedule periodic inspections of the Pointek CLS500.

The inspection can be subdivided into two parts:

1. Visual Inspection: confirm the following conditions:

a. Inside enclosure is clean and dry.

b. Enclosure sealing is intact and functioning properly (not hardened).

c. All screw connections are tight.

d. Ground connections inside the housing are solid.

e. Ground connections outside the housing are solid.

f. The coaxial connector is free of dirt or deposits.

g. No cables or wires are jammed under the cover.

2. Functional Checks

a. Check for required minimum terminal voltage (see page 28 for supply voltage

requirements).

7ML19985GG03 Pointek CLS500 – INSTRUCTION MANUAL Page 57

Maintenance

Page 64

b. Confirm that Menu 08 is set to enable analog fault signalling: display should read

F: Hi or F: Lo. (If there is a fault condition, it will read F= Hi or F= Lo, when buttons

are released.)

c. Check that the current goes to the alarm position (3.6 or 22 mA) if the coaxial

plug is unplugged: at menu 00, the LCD should display – ooL. After the test,

replace the coaxial plug.

d. Confirm that Menu 18 is set to enable digital fault signalling: the LCD should

display F= cc or F= co, when buttons are released.

e. Check that the solid-state output goes to the alarm position (open/close) if the

coaxial plug is unplugged. After the test, replace the plug.

f. Via HART:

Check that the PV goes to 0 pF when the coaxial plug is unplugged, (0.15 pF is

allowed). If it does, switch the output current to 4 mA and check the current

through the loop, then to 20 mA and check the current through the loop. After the

test, replace the plug.

Maintenance

Troubleshooting: Pointek CLS500

If you are unable to change settings:

• Check that keylock level (menu 1F) is set to 0: the display should read PL = 0.

• Check that menu 01 is set appropriately: If Pv = 1, changes can only be made via

HART.

If you can change settings:

• Reset menu 12 to factory settings: press both buttons, and the display should

read FAC A when buttons are released.

If the LCD displays a negative reading, typically around 100 pF, this often indicates a short circuit in the probe assembly:

• Check the enclosure and make sure no water has got in.

• Check that all the connections in the probe assembly are solid.

Delta Range Setting

The Delta Range Setting allows you to commission the unit for overfill or underfill protection where it is impossible to bring the product to those levels in normal process conditions. The default value is the span between URV and LRV, but when you apply Delta Range Setting, it applies the minimum span (1.0 pF).

Overfill protection is used in applications where the probe is normally uncovered. Delta Range Setting adds the minimum span to the Lower Range Value: the result is used to update the Upper Range Value. If the process level exceeds the new URV, a fault is signalled.

Underfill protection would be used in applications where the probe is normally covered. In this case, Delta Range Setting subtracts the minimum span from the Upper Range Value and uses the result to update the Lower Range Value. If the process value drops below the new LRV, a fault is signalled.

The factory setting is for FailSafe High mode1 (selected at menu 1E). When no buttons are pressed, the LCD displays the current mA value. Analog Signalling Mode (a mA reading proportional to level) is not available when FailSafe High or FailSafe Low mode (FSH or FSL) is selected.

2-state Signalling Mode provides a 4 mA or 20 mA output. The settings are relative to a covered probe:

• C: Hi selects a 20 mA signal for a covered probe, which switches to 4 mA if the

probe becomes uncovered.

• C: Lo selects a 4 mA signal for a covered probe, which switches to 20 mA if the

probe becomes uncovered.

Pointek CLS500 is most often used in FSH or FSL mode: Free Programming Mode (FPM) can be selected at menu 1E. See page 72 for detailed instructions.

Set the rotary switch to 7. To change the mode to 2-state High, press the RED (+) button for more than one second: the LCD displays C: Hi. When the button is released, the loopcurrent will switch to 20 mA if the probe is covered, or 4 mA if it is uncovered.

To change the mode to 2-state Low, press the BLUE (–) button for more than one second: the LCD displays C: Lo. When the button is released, the loop-current will switch to 4 mA, and if the probe is uncovered, or 20 mA if the probe is covered.

While the device is in either FailSafe High or FailSafe Low mode, it reads the loop current as 4 or 20 mA (no faults) or 3.6 or 22 mA (fault situation).

(Analog Mode is only available when Free Programming Mode is selected at menu 1E: in that case it may be restored at any time by pressing both buttons simultaneously for more than one second. The LCD displays C: An while the two buttons are pressed, and displays the current reading when the buttons are released.The loop-current will be between 3.8 and 20.5 mA, and will saturate to one of these values if the level goes beyond the Upper or Lower range settings.)

To change the state of the output signals, press and hold both buttons simultaneously: the digital mode outputs (the solid-state switch and the loop-current control in digital mode) change to their opposite state. Thus 4mA becomes 20mA and contact open becomes contact closed. This feature allows you to verify that the output signals are properly processed further on in the PLC/DCS system: if the normal state is non-alarm, changing the state should generate an alarm.

HART1 Communications for Pointek CLS500

Highway Addressable Remote Transducer (HART) is an industrial protocol that rides on top of a 4-20 mA signal. It is an open standard, and full details about HART can be obtained from the HART Communication Foundation at www.hartcomm.org

Pointek CLS500 can be configured over the HART network using either the HART Communicator 275 by Fisher-Rosemount, or a software package. There are a number of different software packages available.The recommended software package is the Simatic Process Device Manager (PDM) by Siemens.

HART Device Descriptor (DD)

In order to configure a HART device, the configurator must have the HART Device Descriptor for the unit in question. HART DD’s are controlled by the HART Communications Foundation. The HART DD for Pointek CLS500 will be released in 2003. Please check availability with the HART Communications Foundation. Older versions of the library will have to be updated in order to use all the features in Pointek CLS500.

Simatic Process Device Manager (PDM):

Appendix C

This software package is designed to permit easy configuration, monitoring, and troubleshooting of HART and Profibus PA devices. The HART DD for Pointek CLS500 was written with Simatic PDM in mind and has been extensively tested with this software.

Description Usage

General Transmitter Information

Damping information

The Pointek CLS500 transmitter implements damping on most of the transmitter variables. The damping setting may vary from 1 (shortest value) to 10000 (longest value).

Non-volatile Memory Data Storage

The flags byte of Command #0 referenced in the Universal Command Specification document, will have Bit #1 (Command #39, EEPROM Control Required) set to 0, indicating that all data sent to the transmitter will be saved automatically in the non-volatile memory upon receipt of the Write or Set Command. Command #39, EEPROM Control, is not implemented.

MultiDrop operation

Pointek CLS500 transmitter supports MultiDrop Operation.

Burst mode

Pointek CLS500 transmitter does not support Burst Mode.

Units conversions

The Transmitter Variable #0 Units are in pF and cannot be changed.

The Transmitter Variable #1 Values may be set to any Units and Value with Command #140. The Transmitter Variable Range Values may be read at any time with Command #141.

The value returned as Secondary Variable (S.V.) is the result of the following calculation:

TV1 = TV0 Dynamic Range Value in percent x ({TV#1}URV – {TV#1}LRV) + {TV#1}LRV.

This method provides a means of converting TV#0 which is always in pF, to alternative units (level or volume).
