Model UD10 DCU Emulator

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 DCU Emulator (UD10-DCU) is designed for applications that require a gas detector with digital readout of detected gas levels. Its LON interface board makes the UD10-DCU compatible with Eagle Quantum Premier systems by digitizing the 4-20 mA analog signal from the attached sensor/transmitter and transmitting the value as a process variable over the LON to the EQP controller.

The UD10-DCU is designed for use with most currently available Det Tronics gas detectors. Refer to the Specifications section of this manual for a list of compatible gas detectors. 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 indicated on a digital display.

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-DCU, or remotely located using a sensor termination box.

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

Description

The UD10-DCU Universal Display can be used with various 4-20 mA gas detection devices, with or without HART. The unit provides display, output and control capabilities for the gas detector.

The UD10-DCU utilizes the following I/O:

Signal Inputs:	4-20 mA loop from the sensing device
User Inputs:	Magnetic switches on the display panel
	S3 Software

Next

To actuate a magnetic switch, lightly touch the magnet to the viewing window of the UD10-DCU 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-DCU 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-DCU. 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-DCU automatically returns to the main screen after 10 minutes if no activity occurs.

Device ENCLOSURE

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

Device DISPLAY

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

•Detector information

•Measurement range

•Alarm setpoints

•Alarm and event logs

For detailed menu structure, refer to the appropriate Appendix.

Configuration overview

The user must select the sensor mode/type manually from the UD10-DCU display. The selection options are:

HART Device (including Generic HART Device) PIR9400

C706x

505 NTMOS CGS

Generic Device (without HART)

When “HART Device” is selected, the UD10-DCU communicates with the detector to determine the device type. The upper and lower range for the UD10-DCU display is determined by the detector type and must be selected before configuration data is sent from the EQP system. If the detector type or range is changed at the UD10-DCU, a configuration download from S3 should again be performed.

Alarm levels and calibration gas concentration level come from the S3 application. Configuration information is downloaded from S3 to the controller, which sends the data to the LON interface board in the UD10-DCU. The LON interface then sends configuration information to the main processor in the UD10-DCU for storage and display. Alarm levels and calibration gas concentration cannot be set from the UD10-DCU menu system, however, they can be viewed after download.

Status information from the UD10-DCU and attached detector is passed to the EQP controller over the LON network, and then to S3 for display.

95-8656

Alarms

The UD10-DCU has a low and high alarm that are set from the S3 configuration software and then downloaded to the UD10-DCU. Alarm status can be viewed at the UD10-DCU display, the EQP controller, or S3. Alarms are non latching at the UD10-DCU, but can be latched using logic within the EQP Controller.

With some configurations, the alarm limits on the UD10 DCU are tighter than on S3. If a value is out of range, the UD10-DCU will set the value as close as possible while remaining within the allowable range (See Table 1). After the configuration download is complete, the alarm setpoints can be viewed at the UD10-DCU under Display Status->LON Config menu.

Calibration Gas Concentration

The calibration gas concentration is programmed from S3 and downloaded to the UD10-DCU. See Table 2 for calibration gas limits. NTMOS, CGS, and PIR9400 require a gas concentration of 50% full scale. Calibration gas concentration can be viewed from the UD10-DCU menu under Display Status->LON Config.

Installation

NOTE

For complete instructions regarding wiring, installation, and use of the Eagle Quantum Premier system, refer to manual number 95-8533.

note

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

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 the Specifications section in this manual 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 3.

If the UD10-DCU 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-DCU.

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-DCU is 2000 feet. Maximum cable length from UD10-DCU 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.

Wiring Procedure

NOTE

Since the UD10-DCU 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. For information on devices not covered in an Appendix, refer to the manual provided by the device’s manufacturer.

Connect 24 vdc power lead wires and communication network cable to the appropriate terminal block. Refer

to Figure 2 for an illustration of the UD10-DCU wiring terminal board.

COM 1 - Communication network connections: Connect to COM 2 terminals of the next device on the loop, A to A and B to B.

COM 2 - Communication network connections: Connect to COM 1 terminals of the previous device on the loop, A to A and B to B.

24 VDC - Connect the “+” terminal to the positive side of the 24 vdc power source. (Both “+” terminals are connected internally.)

Connect the “–” terminal to the negative side of the 24 vdc power source. (Both “–” terminals are connected internally.)

Figure 3 shows a UD10-DCU Wired to a generic sensing device. Refer to the appropriate Appendix for information regarding a specific detector.

Grease/Lubrication

To ease installation and future removal, ensure that all junction box covers and sensor threads are properly lubricated. If the need arises for additional lubrication, use either Lubriplate grease (see Ordering Information for part number) or Teflon tape. Avoid the use of silicone grease.

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.

LON Address Switch Setting

Each device on the LON/SLC must be assigned a unique address. This is accomplished by setting DIP switches on the module’s circuit board. See Figure 2. Each rocker switch has a specific binary value. The node address is equal to the added value of all rocker switches in the “ON” position. All “OFF” switches are ignored. The valid address range is from 5 to 250.

The switch value is read at power-up. If a change is made with power applied (not recommended), power must be cycled before the change will be recognized. The LON address can be read from the UD10-DCU menu under Display Status->LON Config.

For additional information, refer to the Eagle Quantum Premier system manual (number 95-8533).

Recommended Startup

Procedure

1.Check the UD10-DCU LON address switches for proper setting.

2.Check all system wiring for proper connection.

3.With power applied to the system, select the correct sensor type or mode. See “Detector Type/Mode Selection Procedure” for details.

Note

A fault may be displayed until the configuration is downloaded.

4.Note the units on the main UD10-DCU display. (This will typically be PPM or %.)

5.Record the LON address, range, and units for each detector.

6.Complete the steps in the “S3 Configuration” section of this manual to configure the LON network from S3.

Detector Type/mode selection procedure

After power has been applied and the warm-up period is complete, select the UD10-DCU operating mode. To do this:

1.Access the Main Menu by touching the magnet to the ENTER/SELECT button. From there, navigate to the “Mode Select” menu.

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-DCU 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.

note

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

Note

If the UD10-DCU Display is in PIR9400 mode and if:

a.The connection between PIR9400 and the UD10 DCU is removed, the UD10-DCU will show a FAULT on the Gas Screen. When the connection between PIR9400 and UD10 DCU is restored, the UD10-DCU 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-DCU Display until the mode is changed to HART.

RTC

Time and date for the UD10-DCU is automatically set by the EQP controller via the LON network. Changes to the time on the S3 computer will be reflected at the UD10-DCU when the controller RTC is set.

When used with the GT3000, the RTC for the GT3000 can be synchronized to the RTC of the display by going through the Main Menu->Device Setup->RTC->“Sync W/Disp”.

4-20 ma input loop Calibration

If the detector connected to the UD10-DCU is HART enabled, its 4-20 mA output signal can be trimmed. (A detector calibration should be performed prior to trimming the detector output or UD10-DCU input).

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-DCU. 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-DCU using the Previous and Next switches. The UD10-DCU 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-DCU Input Trim

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

Upon entering Input Loop Cal, the UD10-DCU commands the detector to output 4 mA, and then automatically calibrates its own input. The UD10-DCU 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-DCU Sensor Connector. Follow the loop calibration instructions shown by the UD10-DCU 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 and Response 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

Response Test

Self-Test

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

Response Test

This test inhibits the UD10-DCU’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-DCU 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-DCU’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).

Display Backlight Operation

The UD10 can be programmed to turn on the backlight feature of the digital display when an alarm or fault occurs or a magnetic switch is activated. Navigate to the Backlight Ctrl screen.

The backlight automatically turns off 10 minutes after the last Magnetic Switch activation.

If the backlight is on following a magnetic switch activation and then an alarm condition occurs, the backlight will remain on steady and not flash until the 10 minute time-out is complete. Then it will begin flashing.

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.
