Important

Be sure to read and understand the entire instruction manual before installing or operating the gas detection system. This product can be used with a variety of Det-Tronics gas detectors to provide early warning of the presence of a toxic or explosive gas mixture. Proper device installation, operation, and maintenance is required to ensure safe and effective operation. If this equipment is used in a manner not specified in this manual, safety protection may be impaired.

Application

The FlexVu® Model UD10 is recommended for applications that require a gas detector with digital readout of detected gas levels as well as analog 4-20 mA output with HART, relay contacts, and Modbus RS485 (foundation™ Fieldbus option available). The UD10 Universal Display Unit is designed for use with Det Tronics gas detectors listed in Table 1.

The display unit is designed and approved as a ‘stand alone’ device and performs all the functions of a gas controller.

When furnished with the CGS interface board, the device can be used only with a CGS sensor for detection of combustible gas. The UD10/CGS combination is certified as a “Gas Detector”.

Gas concentration and unit of measurement are displayed on a digital display. The display unit provides a linear isolated/non-isolated 4-20 mA DC output signal (with HART) that corresponds to the detected gas concentration.

All electronics are enclosed in an explosion-proof aluminum or stainless steel housing. The display unit is used with a single detector that may be either coupled directly to the UD10, or remotely located using a sensor termination box.

The UD10 features non-intrusive calibration. A magnet is used to perform calibration as well as to navigate the UD10’s internal menu.

HART communication

A HART interface provides device status information and field programming capability.

magnetic switches

Four internal magnetic switches provide a non intrusive user interface that allows navigation through the menu and adjustment of configuration parameters in the field without the use of a HART handheld device. See Figure 1 for switch locations.

Fault Shortcut

Next

To actuate a magnetic switch, lightly touch the magnet to the viewing window of the UD10 directly over the switch icon on the faceplate.

Caution

Handle magnets with care! Personnel wearing pacemakers/defibrillators should not handle magnets. Modern magnet materials are extremely strong magnetically and somewhat weak mechanically. Injury is possible to personnel, and magnets themselves can easily get damaged if allowed to snap towards each other, or if nearby metal objects are allowed to be attracted to the magnets.

note

Det-Tronics offers two magnet options for activating internal magnetic switches. While the two magnets can usually be used interchangeably, the best results will be achieved if they are used as follows: The Magnetic Tool (p/n 009700-001) is the stronger magnet and is recommended for activating the switches on the UD10 viewing window. The Calibration Magnet (p/n 102740 002) is recommended for applications that involve initiating calibration or resetting the detector by touching the side of a metal junction box or detector housing (PIRECL, OPECL, etc). Throughout this manual, the term “magnet” can refer to either device.

Access To Menus

To access the menus, use the magnet to activate the Enter/SeLECT button. This will display the Main Menu.

The actual menu structure varies depending upon the device that is connected to the UD10. Menus for the various devices can be found in the corresponding Appendix in this manual.

Some areas of the menu contain additional information, which is indicated by the presence of an arrow on that particular line. By placing the magnet to the glass over the Enter/SeLECT button, the next screen with the additional information will be shown.

The UD10 automatically returns to the main screen after 10 minutes if no activity occurs.

Quick Access/Shortcut: Fault Menu

To access the fault menu quickly, when a fault is present, touch the magnet to the glass by the PrEVIOUS button.

Relays

The display unit has 4 output relays — high alarm, low alarm, auxiliary alarm, and fault. The relays have form C (SPDT) contacts. Low, auxiliary and high alarm relay contacts are selectable for latching or non latching operation, as well as normally energized or normally de energized (default) coils. During normal operation, the fault relay is energized.

IMportant

Direct connection of 120/240 VAC to the relay terminals inside the UD10 enclosure is not allowed, since switching relay contacts can induce electrical noise into the electronic circuitry, possibly resulting in a false alarm or other system malfunction. If the application requires that AC powered equipment be controlled by the transmitter, the use of externally located relays is recommended.

External relays, solenoids, motors, or other devices that can cause inductive transients should be transient suppressed. Place a diode across the coil for DC devices. See Figure 2.

Figure 2—Transient Suppression for Inductive Loads

4-20 mA OuTpuT Modes

The UD10 offers two operating modes for its 4-20 mA output circuit.

Note

A minimum output of 1 mA is required for proper HART communication.

In the Standard (default) Mode, the linear 4-20 mA output corresponds to 0-100% full scale gas detected at the sensor, with 3.8 mA indicating calibrate mode, and 3.6 mA or lower indicating a fault condition. This mode ensures that the current level is always high enough to support HART communication and must be selected when using HART communication for fault diagnostics.

In Replicate Mode, the output of the UD10 matches the output of the connected detector (except for loop test/trim, response test, calibration, or if the UD10 has an internal fault). This mode can be used with

detectors such as PIR9400 or PIRECL where multiple current levels below 4 mA are used for fault diagnostic purposes.

UD10 with Model PIRECL

PIRECL supports two fault modes: PIR9400 and Eclipse mode. PIR9400 fault mode uses fault codes below 1 mA, while Eclipse mode uses no levels below 1 mA. In the Standard (default) mode, the UD10 programs the PIRECL for Eclipse fault mode to ensure proper HART communication in the event of a fault. In the Replicate mode, the UD10 programs the PIRECL for PIR9400 fault mode.

MODBUS / fieldbus COMpATIBILITY

The UD10 supports RS485 Modbus RTU communication. See Addendum number 95-8639 for details. A model with Modbus RS485 or foundation™ Fieldbus communication (field selectable via jumpers) is also available.

DeviCE ENCLOSURE

The UD10 housing is a 5 port aluminum or stainless steel explosion proof junction box with a clear viewing window.

Device DISPLAY

The UD10 is provided with a 160 x 100 dot matrix backlit LCD display. See Figure 1.

During normal operation, the LCD continuously displays the detected gas level, gas type, and units of measurement. The real time clock can also be displayed if desired.

The display shows the following alarm information:

•High gas alarm

•Low gas alarm

•Aux alarm

The display indicates the following fault information:

•Device fault

•Display fault

The UD10 has smart capabilities to allow easy access to the following information:

•Detector information

•Measurement range

•Alarm setpoints

•Alarm and event logs

For detailed HART menu structure, refer to the appropriate Appendix.

Logging

Events that can be logged in the UD10 include:

•Calibration (Date, time and success Y/N are logged for detectors that do not provide their own calibration logging capabilities.)

Faults that are logged in the UD10 include:

•Detector fault

•Low power

•General fault

Alarms that are logged in the UD10 for gas detector inputs include:

•High gas alarm

•Low gas alarm

•Aux alarm.

The UD10 has its own battery backed real time clock (RTC) and its own event logs. The RTC in the UD10 can be set from the UD10 display, Modbus or HART interfaces. The RTC in the gas detector (any HART detector having an RTC) can be set independently using the UD10 menu, or by using the synchronize command, which will set the detector RTC to the same time as the UD10 RTC. See Figure 3.

The UD10 can display the detector event and calibration logs (if available). The UD10 has its own 1,000 entry event log available under the Display Status >History >Event Log menu.

UD10 event logs can be read from the HART interface or the Modbus interface.

Detector calibration and event logs can also be read from the detector HART interface (where available).

Installation

note

The gas detector housing must be electrically connected to earth ground. A dedicated earth ground terminal is provided on the UD10.

Note

Refer to the Model UD10 Safety Manual (number 95-8668) for specific requirements and recommendations applicable to the proper installation, operation, and maintenance of SILCertified Model UD10 displays.

The detector must always be installed per local installation codes.

Before installing the gas detector, define the following application details:

IdENTIFICATION of vapoR(s) to be detected

It is necessary to identify the vapor(s) of interest at the job site. The fire hazard properties of the vapor, such as vapor density, flashpoint, and vapor pressure should be identified and used to assist in selecting the optimum detector mounting location within the area.

For cross sensitivity information, refer to each gas detector’s corresponding instruction manual. Refer to Table 5 in the Specifications section for a list of gas detectors and their corresponding instruction manuals.

IdENTIFICATION of detector moUNTINg loCATIONS

Identification of the most likely leak sources and leak accumulation areas is typically the first step in identifying the best detector mounting locations. In addition, identification of air current/wind patterns within the protected area is useful in predicting gas leak dispersion behavior. This information should be used to identify optimum detector installation points.

If the vapor of interest is lighter than air, place the detector above the potential gas leak. Place the detector close to the floor for gases that are heavier than air. Note that air currents may cause a gas that is slightly heavier than air to rise under some conditions. Heated gases may also exhibit the same phenomenon.

The most effective number and placement of detectors varies depending on the conditions on site. The individual designing the installation must often rely on experience and common sense to determine the detector quantity and best locations to adequately protect the area. Note that it is typically advantageous to locate detectors where they are accessible for maintenance. Locations near excessive heat or vibration sources should be avoided.

Final suitability of possible gas detector locations should be verified by a job site survey.

The gas detector must be mounted with the sensor in the correct orientation as shown in Table 2.

If the UD10 faceplate is not correctly oriented, it can be rotated at 90 degree increments by pulling the electronic module from the four mounting posts that secure it to the junction box and repositioning it as desired. Note that the module is held in place by a compression fitting – no screws are involved.

WIRING

power SUPply requiremeNTS

Calculate the total gas detection system power consumption rate in watts from cold start-up. Select a power supply with adequate capability for the calculated load. Ensure that the selected power supply provides regulated and filtered 24 Vdc output power for the entire system. If a back-up power system is required, a float type battery charging system is recommended. If an existing source of 24 Vdc power is being utilized, verify that system requirements are met. The acceptable voltage range is 18-30 Vdc measured at the input to the UD10.

note

The power supply must meet the noise requirements for HART systems. If noise or ripple on the main power source could interfere with the HART function, an isolated power source (Figure 11) is recommended. (For detailed information regarding power supply specifications, refer to the HART Communication Foundation’s document “FSK Physical Layer Specification” HCF_SPEC-54.)

Wiring cable requiremeNTS

Always use proper cabling type and diameter for input power as well as output signal wiring. 14 to 18 AWG shielded stranded copper wire is recommended. Correct wire size depends on the device and wire length. Refer to the appropriate Appendix for additional information. The maximum cable length from power source to UD10 is 2000 feet. Maximum cable length from UD10 to sensor is 2000 feet.

note

The use of shielded cable in conduit or shielded armored cable is highly recommended. In applications where the wiring is installed in conduit, dedicated conduit is recommended. Avoid low frequency, high voltage, and non signaling conductors to prevent nuisance EMI problems.

caution

The use of proper conduit installation techniques, breathers, glands, and seals is required to prevent water ingress and/or maintain the explosion-proof rating.

ShIEld CoNNECTIONS

The UD10 provides terminals for proper grounding of wiring cable shields (located on the sensor, 4-20 mA, and operating power terminal blocks). These shield terminals are not connected internally, but are connected to ground through capacitors. The capacitors ensure an RF ground, while preventing 50/60 Hz ground loops.

Ground all shields as shown in the wiring examples throughout this manual.

important

For proper grounding, all junction boxes / metal enclosures must be connected to earth ground.

The following are required for installations requiring CE Mark compliance:

•For shielded cable installed in conduit, attach the wire shields to the “shield” connections on the terminal blocks, or to earth ground on the case.

•For installations without conduit, use double shielded cable. Terminate the outer shield to earth ground on the case. Terminate the inner shield to the “shield” connection on the terminal blocks.

JumpeR SeTTINg for 4-20 mA Loop

In order for the 4-20 mA current loop to operate properly, +24 Vdc must be applied to terminal P1-3. This can be accomplished in one of two ways:

•For a non-isolated 4-20 mA loop, set jumper plug as shown in Figure 4. This applies +24 Vdc to P1-3 via an internal connection to terminals P2-2 and P2-5.

•If the 4-20 mA loop will receive power from a source other than the UD10’s main power source (isolated), set the jumper plug as shown in Figure 5 to remove the internal connection.

FoUNDATION FiEldbus (Optional)

Some UD10 models allow the use of either RS485/ MODBUS or Foundation Fieldbus communication via connection to J2 on the terminal board. Four jumpers are provided to select between the two protocols. If the device is equipped for Foundation Fieldbus, it will be shipped from the factory with the jumpers preset for that mode. If the user wants to switch to RS485/MODBUS (for example, to retrieve logs), the four jumpers can easily be moved. Figures 6 and 7 show the jumper settings for each mode of communication.

Note that the pin identification for the J2 connector is different for each communication protocol. For Foundation Fieldbus it is “– +”. For RS485/MODBUS it is “B A com”.

Wiring Procedure

NOTE

The following section shows the output of the UD10 wired to a generic 4-20 mA signal receiver in various configurations. Since the UD10 can be used with a variety of different detection devices, information that is specific to each detector model (wiring, calibration, HART menus, etc.) is covered in an Appendix that is dedicated to that device. Refer to the appropriate Appendix at the back of this manual for specific information when wiring the detection system.

Device Test

2.From the “Mode Select” menu, select and enter the appropriate operating mode based on the type of detector being used.

note

If using a PIR9400, note that changing the gas type on the UD10 does not change the gas type at the PIR9400. This change is made using a switch located in the PIR9400. Refer to the PIR9400 instruction manual (95 8440) for details.

NOTE

If using a C706X detector, navigate to the “Device Setup” menu and select the appropriate gas type and unit of measurement.

3.To exit, activate Cancel/Escape three times to return to the main display screen.

4.If the detector is replaced with another detector type, the UD10 will not recognize it until the mode is changed.

5.If the UD10 Display is in PIR9400 mode and if:

a.The connection between PIR9400 and the UD10 is removed, the UD10 will show a FAULT on the Gas Screen. When the connection between PIR9400 and UD10 is restored, the UD10 will remove the FAULT indication when current increases beyond 3.6 mA.

b.Someone removes the PIR9400 & connects a HART enabled Gas Detector, it will not be recognized by the UD10 Display until the mode is changed to HART.

2.The first item on the RTC screen is “Displayed”.

Y (Yes) or N (NO) is shown to indicate whether the time and date will be displayed on the main screen. To change the setting, use the Enter/ SeLECT button to go to the next screen, then use the PrEVIOUS or Next buttons to toggle between

Y and N. Once the chosen input is selected, use the Enter/SeLECT button to enter the selection. Use the Cancel/EsCAPE button to exit without changing.

3.Use the same method to set time and date.

Specifically for the GT3000 Transmitter, the RTC for the transmitter can be synchronized to the RTC of the display by going through the Main Menu->Device Setup->RTC-> 1st slot “Sync W/Disp”.

Latching Alarms

The high, auxiliary and low alarm relay settings are programmable and can be set for latching or non latching operation. Alarm configuration can be done using the local display menu or external HART interface. Latched alarms on the display can be cleared through the Display Setup > Alarm Setting submenu using the magnet or external HART interface.

4-20 ma loOp CaliBRATION

Both the input and output current loops of the UD10 are trimmed at the factory. They can also be trimmed in the field for maximum accuracy using the following procedures. If the detector connected to the UD10 is HART enabled, its 4-20 mA output signal can also be trimmed.

When the UD10 is used with a detector that supports HART communication, the output of the detector should be calibrated first.

HART Detector Signal Calibration

Navigate down the menu to Device Test > D/A (Digital to Analog) Trim.

Select Zero Trim. When this screen is entered, a warning message is presented. Select ENTER to continue. When the message “Connect Reference Meter” is presented, install the current meter on the mA line between the detector and UD10. Select ENTER to continue. When the message “Set Input Current to 4mA?” is presented, select ENTER to begin the Zero Trim function. The detector will now set its 4 mA output value. If the value indicated on the current meter is not 4.00 mA, enter the measured value into the UD10 using the Previous and Next switches. The UD10 calculates and corrects for the difference between the actual and entered values. When the current meter value is at the desired 4.00 mA, select ENTER to accept the new zero trim value.

Select Gain Trim. Follow the same procedure for gain/ span calibration.

UD10 Input Trim

When the UD10 is used with a detector that supports HART communication, an automated process can be used to trim the UD10 input. Navigate down the menu to “Input Loop Cal”.

Input Loop Cal

Upon entering Input Loop Cal, the UD10 commands the detector to output 4 mA, and then automatically calibrates its own input. The UD10 then commands the detector to output 20 mA and subsequently calibrates its own input.

If a non-HART detector is being used, the Input Loop Cal may be performed with a mA current source or loop calibrator connected to the UD10 Sensor Connector. Follow the loop calibration instructions shown by the UD10 for this procedure.

OptIONAl SystEm TeSTS

The following tests are available for verifying proper operation of various functions of the gas detection system:

–The Self Test, Response Test, and Loop Test are accessed from the “Display Test” screen. (A “Device Test” screen is available for performing the same tests on HART enabled detectors.)

–The Proof Test is performed by applying test gas to the sensor. It is not accessed from the “Display Test” screen and does not inhibit the outputs.

Self-Test

This test commands the UD10 to perform a fully automatic internal test. At the completion of the test, the UD10 will indicate a pass or fail.

Response Test

This test inhibits the UD10’s outputs, thereby providing a means of testing the system by applying gas to the detector without activating any alarms or affecting the output.

note

If the Response Test is not terminated by the operator, the test will automatically time out after ten minutes and the UD10 will return to normal operation.

Loop Test

This test temporarily forces the UD10’s 4-20 mA output to a specific level. This is an easy way to test the output signal of the UD10 for accuracy, to verify the capabilities of the system, and to verify the input signal of a receiver. To perform this test, connect a current meter to the output loop. Navigate to Display Test and select Loop Test, then follow the prompts on the UD10 Screen.

note

If the Loop Test is not terminated by the operator, the test will automatically time out after one minute and the UD10 will return to normal operation.

Proof Test

A Proof Test (bump test) can be performed at any time to verify proper operation and calibration of the system. Since this test does not inhibit the UD10’s outputs, secure any output devices prior to performing the test to prevent unwanted actuation.

HiSTORy

There are two separate histories, one for the display and one for the detector (if available). Both will state the number of hours that the unit has been operating, and the highest and lowest recorded temperature (with time and date stamp).

DEVICE REPAIR AND RETURN

Prior to returning devices, contact the nearest local Detector Electronics office so that a Return Material Identification (RMI) number can be assigned. A written statement describing the malfunction must accompany the returned device or component to assist and expedite finding the root cause of the failure.

Pack the unit properly. Always use sufficient packing material. Where applicable, use an antistatic bag as protection from electrostatic discharge. The RMI number should be clearly marked on the outside of the box.

note

Inadequate packaging that ultimately causes damage to the returned device during shipment will result in a service charge to repair the damage incurred during shipment.

Return all equipment transportation prepaid to the factory in Minneapolis.

NoTE

It is highly recommended that a spare be kept on hand for field replacement to ensure continuous protection.

ORDERING INFORMATion

Sensor module, transmitter module and termination boxes (if used) must be ordered separately.

Refer to the UD10 Model Matrix for ordering details.
