INSTRUCTIONS
FlexVu ® Universal Display Unit
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
