Siemens 840D Powerline test stand

A.I. engineered a one-man, portable Test Stand for on-site service of Siemens Control CNCs in our Customers’ operating environments.   This 480V-3PH unit is designed for the 840D Powerline Systems [SIMO Drive 611],  testing on-station the complete Siemens System: drives (LT module), power supplies (E/R module), machine control panels (MCPs), control cards, operating panels, NCUs, PCUs and motors.  Our technician brings the Test Stand to the machine (or to an adjacent Repair area), ‘plugs-into’ a 480V-3ph power supply and evaluates a discrete subsystem for potential fault.   The Test Stand reduces machine downtime with rapid fault diagnoses; thereby eliminating costly guesswork and missteps.   Repair and/or replacement of a failed unit can be acted upon immediately following a Test Stand diagnosis.
