1. Scope of Delivery
Indoor Air Quality Guard LGW-13
Mounting material for wall-mounting
24V power supply (optional)
2. Product description
The LGW-13 is a versatile CO2 detector. The device
has an optical (LED) and acoustic warning signal
output (horn). Furthermore, a switching function
for common 24 Volt actuators is integrated for use
in industrial and domestic applications. The CO2
sensor is integrated in a compact housing made of
white polycarbonate (IP 20). The Sensor is based on
the optical measurement principle "NDIR" (non-
dispersive infrared absorption measurement).The
device is available in various measuring ranges from
0...1 Vol% available. The LGW-13 has an integrated
function monitoring and is maintenance-free.
3. Product features
3.1. Measuring Range
The device measures the CO2 concentration in the
ambient air in the range of 0...3000ppm (Standard).
Other measuring ranges up 1,0vol% are available on
request.
3.2. Functions
used as a CO2 sensor with 0-10V and 4-20mA
signal output
Suitable as a tabletop unit with a power
supply or for wall and surface mounting
Air quality traffic light with 10 LEDs
CO2 limit dependent switching function for
24 volt devices
Integrated alarm horn with 2 volume levels
3.3. Technical data
Dimension: (LxWxH): 120x80x35mm
Further technical specifications can be found in the
product-specific data sheet on our website
www.zila.de.
3.4. Operating- and ambient conditions
Operating temperature: -10...+50 °C
Storage temperature: -40...+100 °C
Relative humidity: 0..95 % (nicht
kondensierend)
Air pressure: 900...1100 hPa
3.5. LED bar graph
3.5.1. Internal LED
The LED in the top ventilation slots indicates the
status of the device and the internal monitoring
function. The monitoring function operates when
the device is turned on. If the LED is red, the device
is working properly. If an error occurs, the LED is off.
3.5.2. 10-digit LED CO2 display
The 10-digit display in the standard variant shows
the CO2 concentration in the range of 0...3000ppm
in 10 individual steps with 300ppm each. With
increasing CO2 concentration, more LEDs
permanently turn on from left to right. When
reducing the CO2 concentration in accordance with
the above steps, the corresponding LEDs turn off.
