Lads, I have a Copeland 4DT5 220x Compressor on the low temp side of a Supermarket Rack, its running through a Danfoss Fc102p30 VSD. Im getting alot of 'etr over temp' faults. Was wondering if anyone knew or had ideas on what these faults are.. and if anyone has settings/parameters written down if they use Danfoss vsd /copeland combo's. eg min/max frequency settings etc ps.I know the vsd is 30 kw/40 hp, which is larger than needed for this compressor.
