ATS01

Product references: ATS01N2....LU/QN/RT

Software Versions:

Original Version: There exist a phase loss protection function which eventually created some tripping problems to VERY FEW customers and applications.

V1.1 IE01: 2nd Version, We have added a reset function whenever the tripping phenomenon is encountered. This function can be activated by giving a new run order whenever you encountered a trip. Launched early 2006.

V1.2 IE02: Datecode starting 25 of September 2006 (0639), the phase loss protection has already been taken out of the product hence resolving unwanted cases of "unknown" trips due to Harmonics, opening/closing of downstream contactors and the like. Also with implementation of the 500ms time to reset and wont allow the motor to run if no run order is given within 500ms.

Recommendation: For Thermal Protection of the motor It is a MUST! to place a TELEMECANIQUE Thermal-magnetic Circuit Breaker ( GV* ME , GV7, or better)
