Metal pipes of different non-electric utility systems are frequently mechanically bonded together to become electrically continuous along their path. For example, gas and water pipes become interconnected at hot water heaters; water and sewer pipes interconnect at sinks and appliances;

The built specification of the integrated temperature

The utility pipes providing these services are typically constructed of steel, cast iron, copper, or plastic. Some buried sewer lines may be fired clay. In older facilities, the lines enter the facility at different points and then branch out to form an interwoven tree network of pipes.

 Non-electric utilities. Non-electric utilities are the non-electrical piping used for gas, sewer, and water (both for fire fighting and normal use). In addition to these normal services, the facility will likely contain other non-electric utilities such as fire suppression, chilled water, compressed air, etc.

Temperature sensors are integrated into the servo actuators and motors to protect them from. To protect the servo actuators and motors from temperature overload sensors are integrated into the motor windings. The temperature sensors alone do not guarantee motor protection. Protection against overload of the motor winding is only possible only with an input speed > 0. For special applications (eg load at standstill or very low speed) is an additional overload protection by limiting the overload period.

The built specification of the integrated temperature

 sensors can be found in the technical data. In addition, it is recommended to protect the motor winding against overload by the use of I²t monitoring integrated in the controller. The graph shows an example of the overload characteristic for the I²t monitoring. The overload factor is the ratio between the actual RMS current and continuous stall current.

 that the connectors are correctly attached. Corrosion from the ambient atmosphere (condensation, liquids and gases) at the running surface of the output shaft seal is prevented. Contact between sharp edged or abrasive objects (cutting chips, splinters, metallic or minerals dusts etc) and the output shaft seal must be prevented. Permanent contact between the output shaft seal and a permanent liquid covering should also be prevented. A change in the operating temperature of a completely sealed actuator can lead to a pressure differential between the outside and the inside temperature of the actuator. This can cause any liquid covering the output shaft seal to be drawn into the housing which could cause corrosive damage. As a countermeasure, we recommend the use of an additional shaft seal (to be provided by the user) or the maintenance of a constant pressure inside the actuator.
