Fault message
In an error situation the LED's on theEKA 162 will flash and the relay will be activated.
If you push the top button in this situation you can see the alarm report in the display.
There are two kinds of error reports - it can either be an alarm occurring during the
daily operation, or there may be a defect in the installation.
A-alarms will not become visible until the set time delay has expired.
E-alarms, on the other hand, will become visible the moment the error occurs.
(An A alarm will not be visible as long as there is an active E alarm).
