Hello Guys,
Can someone advise on a problem with a Rittal SK3334.609 mini-cooling chiller.
The unit is about 3 years old and this is the first time it has broken down.
The initial problem was no R134a gas so we called the company that covers the chillers out and they found and fixed the leak, re-gassed and away we go ,but, as this unit is cooling dielectric oil on a spark erosion machine it needs to keep a constant temperature and found that the unit compressor was constantly running and will not cut out and so tried to chill the oil much more than the 2 degree tolerance so have to turn the unit off at the wall until the oil warms up again.
Having looked in the manuals and following the instructions within we tried to fix the Setpoint Temperature and found that it is at 0 Degrees.
Now having tried to change this as the manual stats it will not let us change it, the led stays at zero.
In the Parameters the unit is set at Fixed temperature
We can also change other parameters so the led unit works but cannot fix the Setpoint.
I have contacted Germany and left a message but no reply yet.
Need to sort this so if anyone can advise how to set the temp or whats wrong with the unit that would be great.
Thanks
