Wiring diagram
Functional principle
Signal processors not only supply insertion
and inline sensors with voltage, they also pro-
cess and display the measured signals. De-
vices with MK96…, MS96… and MC96…
housing styles are available. The individual
housing styles are designed for different oper-
ating voltages and feature various output and
supplementary functions. For intrinsically safe
flow sensors it is required to use signal pro-
cessors with intrinsically safe control circuits
of the series MS96…Ex… and MC96…Ex… .

Operating manual
Intended use
This device fulfils the directive 94/9/EC and is suited for use in explosion hazardous areas according to EN50014 and EN50020.
In order to ensure correct operation to the intended purpose it is required to observe the national regulations and directives.
For use in explosion hazardous areas conform to classification
II 1 G and II 1 D (Group II, Category 1 G, electrical equipment for gaseous atmospheres and category 1 D, electrical equipment for dust atmo-
spheres).
Marking (see device or technical data sheet)
Ex II 1 G and Ex ia IIC T6 acc. to EN60079-11 and -26 and Ex II 1 D Ex iaD 20 T95°C acc. to EN60079-11 and EN61241-0 and -11
Local admissible ambient temperature
-20…+60 °C
Installation / Commissioning
These devices may only be installed, connected and operated by trained and qualified staff. Qualified staff must have knowledge of protection
classes, directives and regulations concerning electrical equipment designed for use in explosion hazardous areas.
Please verify that the classification and the marking on the device comply with the actual application conditions.
This device is accessory equipment which features intrinsically safe circuits as well as non-intrinsically safe circuits. It may only be installed out-
side the explosion hazardous area in dry, clean and well monitored areas. If a declaration of conformity or declaration of the manufacturer as a
category 3 device exists, the device may be installed in zone 2. Special conditions for safe operation must be observed. Intrinsically-safe elec-
trical equipment can be connected to the intrinsically-safe connections. All equipment must comply with the demands for operation in the exist-
ing zone of the explosion hazardous area. If the intrinsically safe circuits lead to the dust explosion hazardous zones 20 or 21, it is important to
ensure that the devices connected to this circuit fulfil the demands for category 1D or 2D and are certified accordingly. If the equipment is inter-
connected, it is necessary to perform the "Proof of intrinsic safety" (EN 60079-14). Equipment which has been used once to connect intrinsical-
ly safe circuits to non-intrinsically safe circuits is no longer suitable for subsequent use with intrinsically safe circuits. Relevant regulations ex-
ist for the establishment of intrinsically-safe circuits, mounting of external connection parts as well as the characteristics and laying of cables.
Cables and terminals with intrinsically-safe circuits must be marked. They should be separated from non-intrinsically safe circuits or must fea-
ture appropriate insulation (EN 60079-14). Observe the prescribed clearances to earthed components and connections of other devices to the
intrinsically-safe connections of this device. Unless expressed specifically in the device-specific operating instructions, the approval becomes
void if the device is opened, repaired or actions are performed on the device by someone other than approved experts or the manufacturer. Vis-
ible changes to the device housing, such as brown-black discolourations caused by heat, as well as holes or bulges also indicate a serious dan-
ger. Switch off the device immediately. With the associated electrical equipment the interconnected intrinsically-safe equipment must also be
checked. Inspection of a device with regard to the explosion protection can only be performed by an expert or the manufacturer. The operation
of the devices is only permitted in conjunction with the permitted data printed on the side of the housing. Before any commissioning or modifica-
tion of the device interconnections, ensure that the respective regulations, directives and conditions have been complied with and also ensure
that use is only for the intended purpose and the safety requirements have been fulfilled.
Installation and mounting instructions
Avoid static charging of cables and plastic devices. Please only clean the device with a damp cloth. Do not install the device in a dust flow and
avoid build-up of dust deposits on the device.
If the devices and the cable could be subject to mechanical damage, they must be protected accordingly. They must also be shielded against
strong electro-magnetic fields.
The pin configuration and the electrical specifications can be taken from the device marking or the technical data sheet.
In order to avoid contamination of the device, please remove possible blanking plugs of the cable glands or connectors only shortly before in-
serting the cable or opening the cable socket.
Special conditions for safe operation
The device must be protected against any kind of mechanical damage.
service / maintenance
Repairs are not possible. The approval expires if the device is repaired or modified by a person other than the manufacturer. The most important
data from the approval are listed.
