Page 7: Use Restriction
Modification of parts of the actuator or replacement of components with different and non-original parts is not permitted. The replacement of components with original spare parts is carried out only by SNT. Any different use is to be considered improper and therefore potentially dangerous for the safety of the operators, as well as such as to void the contractual guarantee. -
Page 8: Standard Operating Conditions
4.1.2 Standard operating conditions The actuator must be used in an environment whose conditions comply with the provisions of SNT. The works necessary for obtaining and maintaining that conditions are in charge of the owner and, where applicable, are in charge of the end user. -
Page 9: Installation
6 INSTALLATION The operations described in the paragraphs of this chapter provide both electrical and mechanical connections of the actuator, as well as the execution of test motions at reduced speed and motor torque or with small displacement steps. 6.1 Safety warnings MOTORS CANNOT BE CONNECTED DIRECTLY TO THE ELETRICITY GRID. -
Page 10: Fce Electric Stroke Limit Switches
6.2 FCE electric stroke limit switches The ELECTRIC STROKE LENGTH LIMIT DEVICE allows to limit the actuator stroke length avoiding to reach the extreme positions (mechanical stop) and preventing damage. The FCE device consists of 2 normally closed electric switches installed inside a sealed box made in engineering plastic or aluminium alloy. -
Page 11: Fcp Inductive Proximity Stroke Limit Switches
6.3 FCP inductive proximity stroke limit switches The INDUCTIVE PROXIMITY STROKE LIMIT SWITCHES allow the actuator to stop before reaching the internal mechanical stop avoiding damage. If intermediate sensors are present, they can be used to fix intermediate positions along the actuator stroke length. The inductive proximity stroke end switches are fixed directly on the actuator outer tube in the required position. -
