Robertshaw Controls
Hi All
wondering if any can help.
I need the cut out and cut in resistances for a Robert Shaw MP50-9203 Gaurd-Pak V motor protection system.
Its fitted on a compressor for York LCHM60, at the minute its locked out and I am averaging 1.4 ohms across all three sensors.
If this is within its running parameters then i know its knacked, if it isnt isnt then i will need to look into this further.

Re: Robertshaw Controls
Has the Red L.E.D. on the opto isolation board gone out?
This lights to say motor protection is good.
No light means an issue.
Although I suspect you already know this from what you have said?

Re: Robertshaw Controls
hi coolments york motor protection on these compressors ntc as the motor gets hot then the ohms readings come down,the readings start at around 1.7k and come down to about 300 ohms and then the module cuts out so your readings are fine and your module is knackered,any other compressor problems let me know and i might be able to help
