GEA T.VIS E-20, Инструкция по эксплуатации

Страница: 39 / 112

Technical data: Special terms of use
The unit is designed and certified for simultaneous operation of a maximum of two solenoid
valves. Simultaneous operation of more than two solenoid valves raises the temperature to a
critical and non-certified level.
Cable glands are certified and specified in the test reports and must be used as intended.
The cable glands must be certified at least according to ATEX/UKEX and IECEx IP65.
Special precautions are required to reduce the risk from electrostatic discharge. See installation/
operating instructions.
In the case of dust explosion protection, the IP protection of the housing must not be
compromised. Therefore, bear in mind:
If there is a potentially explosive dusty atmosphere, the T.VIS E-20 must not be opened.
The capacitance measured at the exposed metallic screw connections is 91.8 pF. The user must
determine the suitability of the unit in the end-use application.
The installation of the unit is permitted only in a vertical position.
Technical data: Ambient and process temperatures
Do not exceed the permissible ambient temperature.
The T.VIS E-20 control tops mounted on valves in chapter 6.6 are mounted with a defined
distance to valve process housings and piping systems. The permissible process and media
temperatures for the valve process housing are defined in the valve operating instructions.
Depending on the gasket material, process and media temperatures up to 135 °C (275 °F) and
briefly 150 °C (302 °F) are permissible.
It must be ensured that process and media temperatures above the permissible ambient
temperature do not lead to an impermissible ambient temperature of the T.VIS E-20.
Particular attention must be paid to adjacent pipelines, equipment and other system parts.
Please consider the differing permissible ambient temperatures for gases and dusts according to
chapter 5.2.1.
Technical data: Avoidance of electrostatic charge
The instructions on the warning sign of the T.VIS E-20 must be observed:
