3.1 Overview of Transmitter
Kobold Smart Pressure Transmitters are microprocessor based “smart” pressure transmitters. It uses a piezoelectric/ capacitance pickup optimised & accurately characterised with a patented temperature compensation algorithm for high precision & long-term stable gauge and absolute pressure measurements over a wide range of operating conditions. PAS is a two-wire loop power transmitter and has a standard 4/20mA output scaled for desired output pressure range. In addition, it also offers digital HART® (digital signal superimposed over the analogue output) communication that allows transmitting additional digital parameters/diagnostic information for advanced control systems like DCS, PLC.
This transmitter can be configured remotely via HART® communication through a
HHT (HART® Hand-Held Terminal using DDL or DOF technology) or any HART® enabled PC configurator. This allows critical variables to be changed, configured and tested remotely by users. Note: For HART® Communication a minimum
250~500 Ohm loop resistance is mandatory between power supply and transmitter.
3.2 Software Compatibility
KOBOLD Smart Pressure Transmitters are shipped from the factory with the most up to date firmware. However, as product developments and new features are released a firmware update becomes necessary to incorporate these new changes. As such transmitters with older firmware may restrict certain functions when communicating with an external HHT (Model 275/375HART®
Communicator). There may also be some differences on supported functions on the local push button menu based on the installed firmware revision of the transmitter. This manual is based on firmware Revision 6.3. Function deviations as to firmware Revision are same as in table below:

4.1 Unpacking
When moving the transmitter to the installation site transfer it in its original packaging. Only unpack the transmitter on site of installation to avoid damage during transit.
4.2 Models and Specifications Check
The model name and specifications are indicated on the top name plate fixed to the transmitters. Please check your specification and model supplied for your installation.
4.3 Storage
The following precautions must be observed when storing the instrument, especially for a long period.
(1) Select a storage area that meets the following conditions: a) It is not directly exposed to rain, water, snow or sun light. b) It is exposed to minimum vibration and shock. c) If possible, it is advisable to store at normal temperature and humidity
(approx. 25°C, 65% RH).
However, it can also be stored under ambient temperature and relative humidity within the following published ranges.
● Ambient Temperature:
-40 ~ 80 °C (with LCD module)*
* General use only. For explosion proof versions follow product certification requirements
● Relative Humidity:
5 % ~ 98 % RH (at 40 °C)
(2) When storing the transmitter, repack with original (or similar) packaging that was shipped from the factory.
(3) If storing a transmitter that has already been used, thoroughly clean all wetted parts including diaphragm seals (if installed), process connections/manifolds in contact with process fluid. In addition, make sure before storing the transmitter that remote seal (if supplied) assemblies are securely mounted.
PAS K16/0522 page 9
PAS
4.4 Selecting Installation Locations
The transmitter is designed to withstand severe environmental conditions.
However, to ensure stable and accurate operation for many years, the following precautions must be observed when selecting an installation location.
(1) Ambient Temperature
Avoid locations subject to wide temperature variations or a significant temperature gradient. If the location is exposed to radiant heat from plant equipment, provide adequate insulation or ventilation.
(2) Ambient Atmosphere
Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequate ventilation as well as measures to prevent intrusion or stagnation of rainwater in conduits. Moreover, there should be appropriate ventilation preventing corrosion by rain gathered on conduit.
(3) Shock and Vibration
Select an installation site suffering minimum shock and vibration (although the transmitter is designed to be relatively resistant to shock and vibration)
(4) Accessibility
Select location that provides easy access for maintenance & calibration.
(5) Installation of Explosion Protected Transmitters.
Explosion – protected transmitters can be installed in hazardous areas according to gas types for which they are certified.
4.5 Performing Sensor Zero Trim after Installation
(1) Sensor Zero Trim should be done immediately after transmitter is installed because zero point can shift due to mounting status of the sensor pick up.
(2) For Sensor Zero Trim, make input pressure of transmitter zero prior to initiating zero trim calibration. Any Sensor Trim done in field must be carried out after installation is finalized and with transmitter position fixed. Also, if applying external pressure ensure the display is sufficiently stabilized (after approximately 10 to 15 seconds) before initiating any Trim function.
(3) There are two recommendations for making input pressure “zero”. One is to apply a “zero” pressure source (mandatory for absolute pressure models).
The second option is to open equalizing valve of manifolds and venting to atmospheric pressure (allowed only for Gauge type models).
(4) Sensor Zero Trim can be performed using an external HHC (Hand held calibrator), PC or PDA configurator, and/ or using Zero/ Span local push buttons provided on the transmitter.
(5) When using local push buttons please refer to Chapter 4.7 of this manuals for detailed instructions. If using an external HHT or HART® PC configurator please refer to the user manuals supplied by the third party supplier. page 10 PAS K16/0522
PAS
4.6 Pressure Connections
Warning
Instrument installed in the process is under pressure. Never loosen or tighten the flange bolts as it may cause dangerous spouting of process fluid.
If the accumulated process fluid may be toxic or otherwise harmful, take appropriate care to avoid contact with the body or inhalation of vapors even after dismounting the instrument from process line for maintenance
.
The following precautions must be observed in order to safely operate the transmitter under pressure.
(1) Never apply a pressure higher than the maximum working pressure specified on the nameplate.
(2) Use adequate seals for leak tight process connections and use only quality and standardized parts.
(3) Regularly inspect for signs of leakage and apply corrective actions when necessary.
4.7 Waterproofing of Cable Conduit Connections
Apply a non-hardening sealant (silicone or tape, etc.) to the threads to waterproof the transmitter cable conduit connections.
4.8 Restrictions on Use of Radio Transceivers
Warning
Although the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter or its external wiring, the transmitter may be affected by high frequency noise pickup. To test for such effects, bring the transceiver in use slowly from a distance of several meters from the transmitter, and observe the measurement loop for noise effects. Thereafter, always use the transceiver outside the area affected by noise.
PAS K16/0522 page 11
PAS
4.9 Insulation Resistance Test and Dielectric Strength Test
Since the transmitter has undergone insulation resistance and dielectric strength tests at the factory before shipment, normally these tests are not required.
However, if required, observe the following precautions in the test procedures.
(1) Do not perform such tests more frequently than is absolutely necessary. Even test voltages that do not cause visible damage to the insulation may degrade the insulation and reduce safety margins.
(2) Never apply a voltage exceeding 500 V
DC
(100 V
DC
with an internal lightening protector) for the insulation resistance test, nor a voltage exceeding 500V
AC
(100V AC with an internal lighting protector) for the dielectric strength test.
(3) Before conducting these tests, disconnect all signal lines from the transmitter terminals. Perform the tests in the following procedure.
(4) Insulation Resistance test a) Short-circuit the + and - SUPPLY terminals in the terminal box. b) Turn OFF the insulation tester. Then connect the insulation tester plus (+) lead wire to the shorted SUPPLY terminals and the minus (-) lead wire to the grounding terminal. c) Turn ON the insulation tester power and measure the insulation resistance. The voltage should be applied short as possible to verify that insulation resistance is at least 20
MΩ.
d) After completing the test and being very careful not to touch exposed conductors disconnect the insulation tester and connect a 100kW resister between the grounding terminal and the short-circuiting SUPPLY terminals. Leave this resistor connected at least three second to discharge any static potential. Do not touch the terminal while it is discharging.
(5) Dielectric Strength Test a) Short-circuit the + and - SUPPLY terminals in the terminal box. b) Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY terminal and the grounding terminal. Be sure to connect the grounding lead of the dielectric strength tester to the ground terminal. c) Set the current limit on the dielectric strength tester to 10mA, then turn ON the power and gradually increase the tester voltage from '0' to the specified voltage. d) When the specified voltage is reached, hold it for one minute. e) After completing this test, slowly decrease the voltage to avoid any voltage surges. page 12 PAS K16/0522

PAS includes an EEPROM (Electrically Erasable Programmable Read Only
Memory) that allows saving and restoring various configuration data within the transmitter on power failure. To lock configuration and protect changes to stored configuration data, one can use a HHC and or external HART® enabled PC device to enable a software lock feature under Status menu. Optionally for security lock on hardware side there is a Write-Protect Mode DIP Switch (1) on the Main CPU Module placed right next to the Fail Safe Mode switch (2). If you push DIP switch to UP you can lock out users from making any changes to configuration data through push buttons and/ or remote HHC already saved in the
EEPROM. Alternatively, when you push DIP Switch (1) to DOWN you can allow changes made to configuration data in EEPROM. Default state from factory
(including with NO Jumpers) installed is EN (enable configuration changes).
CPU Module Jumper Switch
1) EEPROM Write Selection
2) Fail Mode Selection
Figure 5-3. CPU Module Fail Mode, EEPROM-Write Selection Jumper Switch
Note: DIP Switch (1) shown on Left in Fig 5-3 is for Write Enable/
Disable selection. DIP switch (2) shown on right in Fig 5-1 is for Fail
Mode.
5.5.1 Security
To quickly summarize there are three options available to implement configuration security lock out within the PAS. These include:
(1) DIP settings on CPU Board
(2) Software enable/ disable on Write function using HHT or HART® PC. (3)
(3) Physically removing Zero and Span Magnetic Buttons from Transmitter thereby restricting local access to push button menus. This option will still allow changes via a remote HHT or HART® enabled configurator.

5.5.2 Zero and Span Magnetic Buttons
To access push buttons please remove top name plate to expose the magnetic style push buttons labelled zero/ span. To disable please unscrew and remove these push buttons.
5.6 Configuration of Alarm and Security Jumper Procedures
To change Jumper/ DIP switch position in field:
(1) If transmitter is already wired and installed, cut off power.
(2) Open the housing front side covers.
Warning: In hazardous areas DO NOT open the covers of
Transmitter when power is energized as this can create a potential dangerous situation. Always kill power and de-energize the transmitter prior to opening front OR back covers in a hazardous location.
(3) Adjust required jumper/ DIP position as detailed in section 5.4 & 5.5 above.
(4) Close the housing covers. You must fully engage all cover threads to ensure compliance to explosion proof requirements
5.7 Configuration of Zero and Span Procedures with Buttons
There are ZERO and SPAN Buttons to be seen when the nameplate is opened
(Figure 5-4). You may reconfigure the function settings of ZERO, SPAN, ZERO
TRIM, ZERO ADJ, Units, Range, Damping, LCD and Decimal place, using
ZERO / SPAN buttons. page 22

(a) Unscrew both name plate screws on upper part of transmitter.
(b) Flip the name plate to access Zero and Span Buttons. (Figure 5-4)
Caution: Do not fully unscrew all screws in order not to lose them.
5.7.1 Advance Configuration via Push Buttons
The advanced “smart” functions which can be initiated using ZERO / SPAN
Buttons are shown below. This includes re-ranging of transmitters (Set URV/LRV) without an external pressure source.
To access advanced configuration and enter programming menu press both
(Zero + Span) buttons simultaneously for 3 seconds. When display reads
“MENU” release both push buttons immediately. This will put user into top of main programming menu indicated by message “1-TRIM” on display. To navigate through Main Menus and/ or Sub-Menus:
(1) Use (Zero) button to scroll down a menu (or sub-menu if active).
Example: Press (approx. 3 sec.) / Release (Zero) to scroll down from Main
Menu 1-Trim> 2-Setup > 3-LCD>1-Trim > 2-Setup etc. Or from an active submenu press/ release (Zero) to scroll down within a sub menu Example 21-
Units> 22-URL > 23-LRL > 24-Damping > 21-Units > 22-URL etc.
(2) Use (Span) button to enter into a specific Sub Menu or data input function.
Example: Pressing (approx. 3 sec.) (Span) button from Main Menu <1-TRIM> will put user into Sub menu “11 ZERO TRIM”. Releasing and pressing (Span) button again will initiate Zero Trim configuration or releasing and pressing
(Zero) button instead will increment user down to submenu “12 Z- ADJ”
(3) Within an active sub-menu use of (Span) button also acts as an <enter> key to allow user to save changes and exit programming mode.
(4) For moving back to previous menu press (Zero + Span) button together.
During numeric value entry mode use (Zero + Span) button together to save numeric data inputted and exit from programming menu. See 5.7.3.3 below
Caution:
- After 30 seconds inactivity the automatic time out feature will default user back to normal measurement mode with a “BT-Err” message on display.
- Please refer to Appendix 1 for LCD display messages and the button errors.

5.7.3.1 Zero Configuration
Sets the current process value for Lower Range Value (4 mA).
Apply zero value pressure for 10 seconds and press ZERO button over 3 seconds. The LCD should display “ZERO”. After checking this message, remove finger from the button.
After 1 second, push the Zero button for 3 seconds. The LCD should display “-
ZR-“. This message means that the Zero configuration is completed and saved.
If Zero Configuration was incorrectly performed the LCD will display error code
“ZR-ERR” indicating failure and possible LRV setting out of sensor range capabilities. Try repeating the Zero configuration steps.
5.7.3.2 Span Configuration
Sets the current process value for Upper Range Value (20 mA).
Apply the desired pressure for 10 seconds and press SPAN button over 3 seconds. The LCD should display “SPAN”. After checking this message, remove finger from the button.
After 1 second, push the Span button for 3 seconds. The LCD should display “-
SP-“. This message means that the Span configuration is completed and saved.
If the Span configuration was incorrectly performed the LCD will display error code “SP-ERR” indicating failure and possible URV setting out of sensor range capabilities. Try repeating the Span configuration steps.
5.7.3.3 STEPS TO INPUT NUMERIC DATA VALUE:
Specific functions that need users to input a numerical value are found in following sub-menus:
12 Zero Adjustment,
22 Change Upper Range Value,
23 Change Lower Range Value,
24 Damping Second
First time users should familiarize themselves with numeric value input sequence prior to accessing above sub menus. Due to limited flexibility with only 2 push buttons available for configuration, it is not possible to directly input numeric values within these sub-menus. Instead, the correct sequence requires user to first set an increment (10x) rate e.g. 0.01, 0.1, 1.0, 10. 100, 1000 etc and then proceed with changing numeric value by the set rate increment.
For example, to input a numeric value as “3810” from existing displayed value of
“0000”:
->First Set increment rate as “1000”
->Increase display “0000” value 3 times in steps of 1000 till it reads “3000”
->Then set increment rate again as “100”
->Increase 8 times in steps of 100 till display reads “3800”
->Set increment rate again as 10
->Increase 1 time for a step change of 10 till display reads 3810.
PAS K16/0522 page 25
PAS
This section outlines the push button sequence for facilitating direct numeric value input from following sub-menus:
“12 Zero Adjustment”, “22 Change Upper Range Value”,
“23 Change Lower Range Value” and “24 Damping”.
When activating these sub-menus (by pushing down & releasing (span) button from within its active menu) the display will automatically prompt for “SEL INC” message.
From here: a) To select an increment rate push down on (Zero) button when “SEL INC”
Message is displayed on LCD sub-menu. Release (Zero) button when display value changes. Each subsequent (Zero) push-release key stroke will shift display decimal point to left. Example when display shows “SEL INC” 1000.
Subsequently for every push release keystroke of (Zero) button the display will cycle from >100>10>1>0.1>0.01>100>10 etc b) Once desired “SEL INC” (0.1, 1, 10, 100 etc) increment rate is set, push the
(Span) button to accept and enable set numeric “VALUE” mode.
Note: When executing (Span) button from “SEL INC” menu the
LCD display will typically show the last saved numerical value along with a “VALUE” message on second line indicating that user can now initiate changes by incrementing or decrementing numeric value. c) From within “VALUE” menu pushing down on either (Zero) or (Span) button
(not both) will allow the numeric value to increment (Zero) or decrement
(Span) by the “SEL INC” value selected by user in the previous step (b). d) After desired numeric value is displayed, push down on (Zero + Span) buttons together to accept new data inputted and this will bring user back to <SEL
INC> menu. Step (a) screen above. e) Repeat steps (a) through (c) detailed above until the final numeric value required is displayed in “VALUE” Menu. f) To store final numeric value to EEPROM push (Zero + Span) button twice to save and exit.
Note pressing Zero + Span once from “VALUE” menu will bring user back to “SEL INC” menu step (a). However pressing (Zero +
Span) buttons together second time (from “SEL INC” menu) and releasing these buttons, when screen shows “INC OK” message, will save the last numeric value inputted and brings the user back to Measurement Mode. g) If the programming sequence is successful, the display will read –DONE- else
“BT-ERR” to indicate failure. If display shows “RANGOVR” it indicates numerical value inputted is out of specs. page 26 PAS K16/0522

5.8 Wiring Connections for External HHT/ Ammeter
PAS Pressure Transmitter can also be commissioned using a HART® enable
HHT or PC configuration either before or after installation. A complete commissioning consists of configuring and/ or verifying transmitter configuration data, testing the transmitter, testing the loop and zero trimming.
For hazardous area installation to avoid exposure of “live” electronic circuits in field it is recommended that all Jumper settings of transmitter (Fail safe, Write disable etc) be done in the shop prior to moving the transmitter on to field installation.
▲ Note:
Test pins can be used to connect an Ampere meter for measuring output current without disconnecting loop connections or for connecting a remote indicator. You cannot initiate HART® digital communication if connecting a HHT directly across "TEST" pins. Use terminals marked communication for connecting an external HART® MASTER. You must ensure a minimum of 250~550 ohm resistance in Current
Loop for any HART® Communication or PC configuration to work. If needed connect a 250 ohm resistor in loop to enable digital communications. Also, for correct operation of a 4~20 mA loop, required power supply (11.9 V ~ 45 Vdc) must be provided at supply inputs marked (+) and (-).

6. Installation
6.1 Overview
The information in this chapter 6 covers installation considerations. Dimensional drawings for Model PAS variation and mounting configuration are included in this chapter.
6.2 Safety Message
Procedures and instructions in this chapter may require special precautions ensure the safety of the personnel performing the operation. Information that raises potential safety issues is indicated by a warning symbol
(▲). Refer to the following safety messages before performing an operation proceeded by this symbol.
6.3 Warning
▲
Warning
Explosion can result in death or serious injury:
Do not remove the transmitter covers in hazardous locations when the circuit is live.
Transmitter covers must be fully engaged to meet explosion proof approval requirements.
▲ Warning
Electrical shock can result in death or serious injury. If you install transmitter around a high voltage environment e.g. power lines there may be a very high likelihood of high voltages induced on to the signal lines.
Avoid direct contact with the signal leads and terminals to avoid potential electrocution.
▲ Warning
Process leaks can cause death or serious injury:
Install and tighten before applying pressure. Inspect regularly for process leaks
▲
Warning
Electrical can result in death serious injury:
Only qualified & trained personnel should be allowed to operate these transmitters.
▲
Warning
Instrument installed in the process is under pressure. Never loosen or tighten the flange bolts as it may cause leakage of process fluid.

PAS
6.5 General Considerations
The PAS transmitter uses a piezoresistive pick up. As changes in pressure are accurately detected, any zero shift or installation offsets will be transmitted as a pressure change on the 4~20 mA analogue current output. Hence it is recommended that the transmitter be mounted as close to the process as possible and use short impulse piping, when possible, to achieve best accuracy.
However, it is equally important to be mindful of basic requirements including ease of access, safety of personnel, practical field calibration accessibility and a suitable transmitter environment when selecting a mounting location. In general, install the transmitter so as to minimize vibration, shock, and temperature fluctuations.
6.6 Electrical Considerations
The internal of the transmitter housing comprises of two sections. The front section is for the electronics module, and Rear side is for the terminal block. On backplane of the Rear Cover “Field Wiring Diagram" is included for easy identification. This can be accessed by opening the rear housing cover and exposing the terminal block inside. Terminal blocks have polarity cleared marked for supply, TEST and communication connections. Please connect transmitter power to supply connections with proper polarity. Hand held configurators connect directly to "COMM" pin provided below the Supply connections. Similarly, a remote field Indicator or current ammeter can connect to "TEST" pins provided.
Though transmitter is protected from reverse polarity protection it is recommended not to apply incorrect polarity across TEST pins as it may damage the protection diodes included.
6.6.1 Power Supply
For powering transmitter an external DC voltage between 11.9V~ 45 Volts DC is recommended. The external power supply ripple noise should not be higher than
2 %. When calculating loop resistances please include resistance of all devices added in the loop.
Max. Loop Resistance [Ω] = (E
-11.9) [Vdc] / 0.022 [mA]
Here, loop resistance of minimum 250 ~ 550
Ω (@24 Vdc) is recommended for
HART® communication. page 34 PAS K16/0522
PAS
6.7 Wiring
6.7.1 Cautions during Wiring
(1) Install signal cables away from electrical noise resources like capacitive transformers, motors, power supplies where possible.
(2) Before wiring pull out the electrical lead connection cap included and replace with appropriate cable glands.
(3) Please use waterproof sealants on conduit screws. Use of silicon based sealants is recommended when possible.
(4) Do not run signal lines & power lines in same cable duct to reduce noise on signal lines.
(5) For explosion-proof transmitters in order to maintain explosion-proof requirements please follow additional local electrical codes and practices where applicable.
6.7.2 Selection of Wiring Materials
(1) Use PVC shielded wire or standard lead line of same class or cable rated for
600 V or higher. In order to ensure proper communication use 24 AWG or larger wire specs, and do not exceed 1500 meters.
(2) Use twisted pair double shielded wires in high electrical noise affected areas.
(3) For high or lower ambient temperature areas ensure wires or cables installed also meet the operating temperature specs.
(4) Similar use appropriate insulation in environment with high likelihood of oil, solvent, toxic gas or liquid spills.
(5) Wiring leads must NOT be soldered to terminal lug. Use the mounting screws included instead to ensure a tight rigid hook up to the terminals.
6.7.3 Connections of External Wiring to Transmitter Terminal Box
Wiring method is as follows:
(1) Open the housing cover indicated "FIELD TERMINAL". NOTE: For hazardous environments do not open the covers when transmitter is powered and circuits are live.
(2) Connect the power supply in the terminal indicated "+PWR" (left terminal) and
"-" power supply in the central terminal. Do NOT connect "+" power supply in
"+" terminal of the point indicated "TEST". It will damage the test diode used for connecting TEST terminal.
(3) Seal and close unused conduit connections to protect transmitters from severe humidity and explosive gases from entering into the terminal box compartment.
(4) Avoid running signal wiring near AC or high power lines. In case of ground signal, ground the signal loop's on one side making sure other side is not grounded.
(5) Ensure loose contacts are eliminated and proper wiring connections are maintained.
(6) After wiring replace transmitter cover. In case of explosion proof areas, you must satisfy all requirements to maintain certification requirements.
PAS K16/0522 page 35
PAS
(7) Do not supply high voltage AC power into transmitter leads as it can cause permanent damage to transmitter.
(8) Use surge protectors to protect transmitter from external power surges.
(9) Ensure you have a 250~600 W Loop Resistor in current loop (between power supply and transmitter) for proper HART® Communication. Follow Figure 6-2 below for wiring instructions.

Only Exd-certified cable conduits, cable glands and blanking plugs with corresponding temperature limits may be used with certified instruments in hazardous areas (Blanking plugs supplied with standard scope of delivery are not
ATEX-certified and must be replaced by the customer with certified blanking plugs).
6.7.5 Grounding
(a) Grounding should satisfy typical requirements (grounding resistance 10 Ohm or less). Grounding is required below 10 Ohm for explosion proof requirements.
Note! In case with Built-in Lightening Protector, grounding should satisfy special requirements 1 Ohm or less)
(b) There are ground terminal provided on the inside and outside of the terminal box. Either one of these terminals may be used for grounding the transmitters.

2“ Pipe Mounting Bracket
Model: ZUB-PAD/PAS-K
PAS K16/0522
PAS
6.8.1 Mounting
During installation provide transmitters with adequate support. In the case of severe vibration, we recommend mounting to a 2” pipe using appropriate mounting bracket available as option. Kobold offers two styles of mounting brackets in SS. These include an “Angle type” and a “Flat type”.
6.8.2 Transmitter accessibility
When selecting a suitable location to install the transmitter it may be convenient to also consider following options.
(1) Ensure adequate clearance is provided for rear cover access and wiring terminals.
(2) If LCD option is installed provide adequate access for front.
(3) Housing can be rotated up to 180° clockwise or 90° anticlockwise to provide easy access to front (or rear) of the transmitter. When rotating housing loosen lock nut placed above neck tag and ensure that sensor cable connectors are not damaged.
(4) LCD Module can also be rotated 90° clockwise or anticlockwise, if required.
6.9 Environmental Considerations
6.9.1 Effect of Ambient Temperature
Transmitter is recommended for use within -40C to 80C operating ambient temperature range. Recommended installation for continuous operation is -20C to
60C with appropriate heat tracing or insulation provided if installing outside of these limits for extended periods.
6.9.2 Toxic/ High Humidity considerations
Housing of PAS Smart transmitters is protected from direct exposure to moisture or toxic materials provided front and rear covers are engaged fully with appropriate O-rings included. Electronic circuits are separated from terminal side; however, it must be protected from moisture ingress entering housing through conduit lines. To avoid moisture build up, use appropriate water tight sealants on conduits entries and ensure correct positioning of conduit pipes to avoid condensation build up from occurring inside the terminal housing.
6.9.3 Installation in Hazardous locations
Transmitter Housing is designed to meet explosion proof protection requirements, if marked accordingly. When installing transmitter inside a hazardous classified area please ensure all required explosion proof installation & wiring requirements outside of the transmitter as stated by relevant regulatory bodies are also complied with.

7. On-line Operation
7.1 Overview
This chapter describes configuration functions of PAS smart pressure
Transmitter. Transmitter can be configured in either On-Line or Off-Line mode. In
On-Line configuration mode, you must connect through an external HHT (Hand
Held Terminal) supporting HART ® DDL technologies. When connecting in Multidrop mode ensure each device on the HART ® bus is provided with a unique
HART ® device ID for identification.
7.2 Safety Message
For safety of operator please pay specific attention to safety note identified under
Warning symbol (▲).
7.2.1 Warning
▲
Warning
Explosion can result in death or serious injury:
Do not remove the transmitter covers in hazardous areas when the circuit is live.
Before connecting HHT in a classified zone, check that the configuration device connecting to transmitter also complies to required safety regulations.
Both transmitter covers must be fully engaged to meet explosion proof certification requirements
7.2.2 Multidrop Mode
In the case of multidrop mode where current loop is set at 4 mA the current loop must be set to passive mode. This is set automatically when chancing the
HART® device ID to a numeric value 1 to 15 (except 0).
7.3 Configuration Data Review
In case transmitter is already installed on site, review configuration data to reconfirm it meets the application requirements.
7.4 Check Output
Transmitter is provided with a Loop Test function (accessible only via an HHT) under service/ maintenance menu which can be used to output desired values 4,
8, 12, 16, 20 mA for testing current outputs. page 44 PAS K16/0522
PAS
7.4.1 Process Variable
The PAS Smart pressure transmitter measures two variables. Primary Variable is always the process pressure measured and SV (Secondary Variable) is the temperature.
Note: Temperature measured is used strictly for internal compensation. Only PV value can be assigned to current output on a 4~20mA loop. However, in digital mode both PV and SV can be read through a compatible HART® communicating device.
7.5 Basic Setup
This involves configuring minimal settings required to operate transmitter correctly.
7.5.1 Select Sensor Range
This value is automatically set from factory based on the sensor Range code installed on the transmitter. This Range defines the minimum/ maximum range limits and span settings for installed sensor which should not be exceeded for normal operation or during re-ranging or Zero/ Span configuration.
7.5.2 Set Output Units (Measurement)
Select required measurement units e.g. kPa, kg/cm2, bar, psi, mmH2O etc.
Note: This is different to engineering mode unit as settings configured under this menu affect only the transmitter current
4/20mA output configuration. In normal LCD mode these units are indicated on LCD module.
7.5.3 Rerange
Set the Zero and Span of 4~20 mA analogue output.
7.6 Detailed Setup
7.6.1 Set Fail Mode
Sets failure mode (fail down or fail up) for 4/20mA outputs in case of an error or malfunction detected automatically during self diagnostic routine included within the transmitter.
PAS K16/0522 page 45
PAS
7.6.2 Set Damping Time
Determine the appropriate damping setting based on the required response time, signal stability and other requirements of the loop dynamics of your system. The default damping value is 1.0 seconds, and can be reset to damping values between 0 and 60 seconds.
[ Graph illustrating Damping/ Response time features ]
7.7 Tag Information set up
7.7.1 Set Tag
Set tag information to uniquely classify transmitter. Tag information is limited to max of 8 alpha-numeric characters. For additional description use Set Message option under 7.7.2.
7.7.2 Set Messages
When using several transmitters, user may classify each transmitter by using 32 alpha-numeric characters. This message is saved in EEPROM of transmitter. page 46 PAS K16/0522
PAS
7.8 Diagnostics and Services
7.8.1 Loop Test
The Loop Test verifies the output of the transmitter, the integrity of the loop, and the operations of any recorders or similar devices installed loop. Perform the following procedure for a loop test.
1. Connect a reference meter to the transmitter.
2. Select the Loop Test of HHT and operate the Loop Test.
3. Select output current ( 4 mA / 20 mA / etc )
4. If the readings match, then the transmitter and the loop are configured and functioning properly. If the readings do not match, then you may have the current meter attached to the wrong loop, there may be a fault in the wiring, the transmitter may require an output trim, or the electrical current meter may be malfunctioning.
7.9 Calibration
Re-Ranging scales the upper and lower ranges of transmitter outputs and does not affect the stored calibration data of the transmitter. On the other hand, a
Sensor Trim function can be used to tune/modify the stored calibration. It is important to keep in mind that Smart transmitters operate differently from conventional analogue transmitters. A Smart transmitter uses a microprocessor that contains information about the sensor's specific characteristics in response to pressure and temperature inputs which is what is used for calculating final PV
(Process Variable). These calibration curves are performed under traceable laboratory standards and stringent quality control parameters. Changing factory calibration data is advisable only if it is necessary to correct transmitter offsets and only when checking against a traceable calibration source which is at least five time more accurate than the transmitter under test. As such a Sensor trim and Output Re-range function differ. Re-ranging sets the transmitter analogue output to the selected upper and lower range points and can be done with or without an applied pressure. Re-ranging does not change the factory characterization curve stored in the microprocessor. Sensor trimming requires an accurate pressure input and adds additional compensation that adjusts the position of the factory characterization curve to optimize transmitter performance over a specific pressure range.
7.9.1 Sensor Trim
The Sensor trim function adjusts the A/D signal conversion within the transmitter sensor electronics and determines how it digitally interprets any pressure changes applied to the sensor inputs. It is highly recommended to perform a sensor trim when first commissioning the transmitter on site. There are three ways to trim the sensor: Sensor zero trim, full trim and zero adjustment.
PAS K16/0522 page 47
PAS
Sensor zero trim is a one-point adjustment typically used to compensate for the mounting position.
Two point trim is a full sensor trim, in which two accurate pressures with difference within the published sensor span specifications for the specific range codes are applied (equal to or greater than the range values), and the output is set to linear. You should always adjust the low trim value first to establish the correct offset.
Zero adjustment allows user to add a pre-defined offset (other than zero) to measured PV that may be required on certain applications such as Level measurements to compensate for nozzle placements.
7.9.2 DA (Digital to Analogue) Trim
The Sensor Trim functions adjust the calibration values of the PV applied to sensor (on input side only), however a D/A trim adjusts sensor input to match the
4~20mA current output. When executing a D/A trim the current output can be adjusted minutely to match desired current values outputted from the transmitter.
To perform a D/A Trim a precise and traceable reference current meter is required to be connected on the output loop. When performing a D/A trim avoid using TEST pin and try to install reference meter directly in series in output loop to eliminate any undesirable offsets. Here again make sure that reference meter used for D/A trim is 5 times more accurate than published accuracy specs. of the transmitter. When performing a D/A trim it is recommended to do a minimum of two points i.e. trim at (4 mA) and (20 mA). It may however be necessary to perform repeated trims at both 4/20 mA to achieve optimum results.

8.4 Hardware Maintenance
KOBOLD PAS Smart Transmitters have no moving parts and require a minimum of scheduled maintenance. Both transmitters feature modular design for easy maintenance. If you suspect a malfunction, check for an external cause before performing the diagnostics as discussed later in this section. If you must return failed transmitters or parts, send them to KOBOLD Messring GmbH for inspection, repair, or replacement.
8.4.1 Test Terminals
The test terminal is clearly marked as TEST on the terminal block behind the rear cover. The test and negative terminals are connected internally via a diode. As long as the voltage across these terminals is kept below the diode threshold voltage, no current passes through the diode. To ensure that there is no leakage current through the diode while making a test reading, or while an indicating meter is connected, the resistance of the test connection or meter should not exceed 10 ohms. A resistance value of 30 ohms will cause an error of approximately 10 percent of reading.
