Notes and
regulations
to be
observed
Observe
– the contents of these operating instructions and references to other documents and their contents
– the safety instructions attached to the mass flow meter
– the application data indicated in the calibration certificate
– the appropriate and valid safety instructions for the construction and operation of electrical systems
– the appropriate and valid safety instructions for handling gases
– the regulations and directives regarding explosion protection.
During
operation
The operator must commission a qualified electrician to inspect and examine the system at defined intervals.
The examination intervals must be chosen in such a way that any damages that can be expected can be recog-
nised in time.
The examinations must be performed at least every three years.
The examinations can be skipped if the electrical system is continuously monitored by a responsible engineer.
Duties of the operator:
– maintain the system in proper condition
– continuously monitor the system
– execute required maintenance and repair work immediately
– carry out required safety measures.
If the devices are used in areas where dusts can cause explosion hazards, you must clean the devices
frequently.
Use genuine spare parts, only.

Notes concerning the use in potentially explosive areas
Only FMT400-VTS is available in a version authorized for use in zone 2 / zone 22. These devices come supplied
with an EU declaration of conformity (ATEX). For devices authorized for use in zone 2 / zone 22, only the data
and instructions for use stated in the declaration of conformity (ATEX) shall apply.

Notice according to the German Hazardous Material Directive
According to the German Waste Disposal Act dated 1986-08-27 (AbfG. §11 Special Waste) the owner of special
waste is responsible for its disposal. According to the German Hazardous Material Directive dated 1986-10-01
(GefStoffV, §17 General Protection Duties) the employer is also obliged to protect his employees. Therefore, we
must point out the following:
a) All flow sensors and/or flow transducers sent to ABB Automation Products GmbH for repair must be free of
any hazardous substances (acids, lyes, solutions, solids).
b) Flow sensors must be flushed and rinsed in order to neutralize hazardous substances. Flow sensors have
cavities. Therefore, the cavity must be neutralized after operation with hazardous materials (refer to German
Hazardous Material Directive, GefStoffV).
c) In case of service or repair, the measures listed in a) and b) must be confirmed in writing. This signed confir-
mation (return report) must be enclosed with the device whenever a device is returned to the factory.
d) Costs arising from increased efforts for handling of contaminated devices and the disposal of hazardous sub-
stances during repair shall be invoiced to the owner of the device!
