1.2 Purpose

The Multitec 560 can be used as a gas measuring and gas warning device.
The device is tted with infrared sensors for measuring hydro­carbons CXHY and carbon dioxide CO2 as standard. It can also be equipped with electrochemical sensors for measuring O2, H2S and CO.
The infrared sensors operate on the principle of absorption via infrared-active gases, and the electrochemical sensors operate on the electrochemical cell principle.
Multitec 560 as a gas warning device
As a warning device it is used to monitor the ambient air at the workplace. The device can measure up to ve gases simultane­ously, thus offering comprehensive protection against dangerous gas concentrations. It provides warnings including:
● explosive gas concentrations
● lack of oxygen/excessive oxygen
● toxic gases
Multitec 560 as a gas measuring device
As a gas measuring device it determines the composition of gas
mixtures that are formed in biological processes (biogas, landll gas). It measures the concentration of several gases in the gas
mixture simultaneously. The device is ideal for use in waste dis­posal sites, sewage plants and biogas plants.
Note: These operating instructions describe the Multitec 560 with all
additional equipment (rmware version 1.XXX). All descriptions refer to the device as delivered (factory settings). The manufac-
turer reserves the right to make changes.

1.3 Intended use

This device is intended for professional residential and commer-
cial use including small rms and commercial operations. The
appropriate specialist knowledge is required to operate the device.
The device may only be used to measure the following gases
(depending on additional equipment):
● Methane CH
● Carbon dioxide CO
● Oxygen O
● Hydrogen sulphide H2S
● Carbon monoxide CO
The device must not be used for:
● Gas analysis of technical processes
● Monitoring liquids
The device can be used up to a temperature of 40 ºC. However, high temperatures reduce the lifetime of the sensors and re­chargeable batteries.
If a device with an electrochemical sensor is exposed to gas concentrations above the measuring range limit, this can reduce
the lifetime of the sensor.

2.1 Visual and audible signals

The device features two alarms:
● Signal light on top of device (visual signal)
● Buzzer on side of device (audible signal)
The signals indicate alarms and faults (see Section. 6 on page 49). The device also emits signals when it is switched on and off.
If this symbol appears on the display, the audible signal can be switched off.
When an audible signal has been switched off it cannot be switched back on.
This symbol appears at the top left of the display as soon as the audible signal has been switched off. It disappears automatically if the level falls below the alarm threshold.

2 Features

Operating signal
Only applies to Warning ExTox application.
The device emits a visual signal and an audible signal at regular intervals. This indicates that the device is working properly.
Alarm
Only applies to Warning ExTox application.
The device can monitor several gases at the same time. If the measured gas concentration of one or more gases exceeds spec-
ied limit values (alarm thresholds) the device gives a warning. It
emits both audible and visual signals, which are distinctly different from the operating signal.
