1. Function and application field
Automation complex SEM-3 for carrying out the acceptance tests of electric drives «EPC-100/400/1000/4000/10000» (short title "Stand SEM-3" ) is intended for carrying out tests of electric drives of stop valves manufactured by JSC TomZEL in particular for controlling the torque limitations of the electric drives, accuracy of stopping down and correctness of operation of remote control and signaling systems of the control blocks. Stand SEM-3 is able to test EPC electric drives with maximum torque 100 N·m to 10000 N·m in automated mode, with making reports about values of controlled parameters. Stand SEM-3 is intended for carrying out acceptance and standard tests of electric drives EPC and their analogues.
