4.3 Indications on the CONA
®
-control system
The LEDs on the "central status indication" light up continuously to indicate the existence of
a fault. As soon as the steam trap functions correctly again, the LEDs blink to show that the
faults are no longer present. By pressing the Reset button, you can reset a stored fault.
* If the "central status indication" is used, the fault is stored and the "Trap Inspect" LED
blinks.
