Model UD10

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 specied 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.

These switches are used for device conﬁguration,

checking status and event logs, and performing

calibration. The switches are labeled as follows:

CANCEL / ESCAPE

ENTER / SELECT / MENU ACCESS

PREVIOUS or if on Main Screen:

Fault Shortcut

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/debrillators 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.

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 communi-

cation. 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:

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).

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 specic requirements

and recommendations applicable to the proper

installation, operation, and maintenance of SIL-

Certied 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.
