Datasheet

Accessories overview Controller unit
Used for a centralized monitoring and warning.
The input signals for the controller are collected
via RS485 Modbus or analog communication.
The controller can handle up to 96 digital
sensors via Fieldbus and four (4) analog input.
An additional 28 analog input is possible using
seven (7) expansion modules (4-20 mA signal
interface). The total number of connected
sensors should not exceed 128 sensors. The
controller unit can be employed as pure analog
controller, as analog/digital, or as digital
controller. Conguration is menu-driven via the
keypad. For fast and easy conguration, the PC
Tool is recommended.
Controller solution
Controller unit placed in an enclosure ready to
be connected to a power source. A separate UPS
for the controller is available.
Warning module (wire break monitoring module)
The warning module is used for monitoring the
circuiting to the warning/alarm devices on a
centrally controlled gas detection system. Wire
breaks or wire interruptions in the alarm device
loop will be reported to the central control.
Controller expansion module
The gas detection Controller Expansion module
is used for expansion of the cable coverage in
terms of number of loops and the total wire
length. Each Controller Unit can handle up to
7 Expansion modules allowing additional 7
segments with a total of 7200 meters (23622 ft.)
wiring and a total of 32 relays for alarm device
circuits.
Service tool
For interface with units with no display (Basic,
Basic+, Premium, Premium+). Acts as a portable
display and can be connected to all Danfoss gas
detection units. (Heavy Duty w. adapter).
PC tool
The PC tool is a menu-driven and standalone
software used for easy addressing, parameter
setting, calibration, and data logging of the
Basic, Premium and Heavy Duty gas detection
units, and the controller unit.
Calibration adapter
The calibration adapter is required for
connecting the calibration gas container, via the
ow regulator, to the sensor head on the gas
detection units. (Two variants, One for Basic and
Premium plastic head sensors; one for heavy
duty and Premium remote metal head sensors.).
Buzzer & light - acoustic buzzer and optic led
Can be installed in Basic or Premium units
providing a local alarm.
Air duct set
The air duct set is specially designed to capture
the airow in air ducts. It can be connected to
the standard sensor heads, except from Heavy
Duty gas detection units.
Seal cap
Airtight seal cap to protect the sensor head
against premature exposure during installation.
The seal cap is mounted on new sensors
(complete units and replacement sensors) but is
also available as an accessory.
Splash guard
To protect the sensor head against water
exposure during wash-down cleaning and rinsing
operations.
Gateway for controller
The gateway is an addition to the controller and
used for communicating via Modbus TCP/IP.
Remote kit
Enabling installation of a sensor head in plastic
housing 5m (16.4 ft.) from the unit. This means
that the gas detection unit can be placed
outside the room where the sensor is placed
to detect hazardous gases, allowing reading of
and interfacing with the unit without entering
the dedicated space. Basic and Premium gas
detection units.
