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
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.
