CONDENSER_TEMP_MON
Condenser coil temperature monitor: capacity permissive with hysteresis, ice-load rate-of-rise trend and a latched overload.
When to use it
Use CONDENSER_TEMP_MON when the ice condenser of a freeze dryer must be proved cold enough to keep taking the sublimation load before and during primary drying, and its coil temperature is the only measurement of that capacity.

Download CONDENSER_TEMP_MON — free
Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
