This is a Product Safety Notice. The filter has determined that certain software program versions on Vilter flashcards (part number 3485FCSD) in Vission 20/20 panels shipped between September 24, 2019, to January 3, 2021, could cause the Vilter compressor to operate beyond preassigned operational limits and fail to activate the safety shutdowns. This software circumstance has been found to arise when the Vission 20/20 panel is connected to an outside third-party monitoring system and the monitoring system sends a simultaneous start/stop command to the compressor. This situation could result in the compressor operating fully unloaded with certain fault conditions not monitored as intended, resulting in an overheated and seized compressor. To date, Vilter is aware of two incidents where this situation occurred.Affected Vilter products can be identified by checking the software program version located on the front screen of the Vilter Vission 20/20 Panel (see Figure 1). If the software program number on the front screen is one of those listed below, the Vilter Visions 20/20 Panel is affected and a software update is required to be performed by a Vilter technician, a Vilter Distributor, Contractor, or by the end-user according to Vilter provided instructions.
If you determine your flashcard is using one of the affected software versions, the Vilter Vission 20/20 Panel software should be immediately updated with a new flashcard. This software update should occur whether or not your system is connected to an outside third-party monitoring system.
