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.
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.
