Manitowoc S Series Ice Machine Safety Timers January 15 2015, 4 Comments

Manitowoc S Series ice machines are considered the best commercial ice machines produced.  They had just the right mix of new technology and old technology that made a reliable, long lasting piece of equipment.  The longevity of the S Series, like model SY0454A, SD0302A, SY0304A, and SY0604A, is due to the control boards ability to protect expensive components with safety timers.

Safety timers are used to shut off the ice machine, in case an ice making cycle is out of spec.  This provides protection to a compressor, that may be short cycling, or loss of water through inlet valves.  Below are the 3 main safety timers, which are indicated by flashing safety limit lights on the control board.
