The troubleshooting of E3 alarm of S&A water chiller CW-5200

E3 means over low water temperature alarm

When alarm occurs

The error code and the temperature will be alternately displayed

The alarm sound could be suspended by pressing any button

Under low ambient temperature( e.g. in winter)

When the cooling water temperature is lower than factory setting startup temperature

It is easy to cause E3 alarm

Now I show you the simple troubleshooting of E3 alarm

1.Startup machine(e.g. laser) to rise cooling water temperature

E3 alarm will be automatically eliminated

2.If the chiller works in a larger temperature difference

Add warm water into the water tank until the water temp restore to normal value

E3 water temperature alarm can be eliminated

If the chiller continues alarming

It is possible that temperature controller or sensor is faulted

Thanks for using S&A chiller.
