The central status indication integrates an AS-i power supply and an AS-i master / gateway.
It allows up to 30 steam traps to be centrally monitored. The AS-i master / gateway has a
PROFIBUS interface as standard to enable all status indications to be evaluated by a
higher-level control. Faults that are indicated when the plant or part of the plant is started up
or shut down can thus be reliably suppressed.
If the status indications are separately evaluated by the "central status indication", the PLC
software in the AS-i master is required. The LEDs on the "central status indication" light up
continuously to indicate the current status of each device. If a fault is detected, it is stored
and a "Trap Inspect" signal is sent to the corresponding measuring amplifier over the AS-i
bus. As soon as the steam trap functions correctly again after a fault has been cleared, the
LED on the central status indication blinks to show that the fault is no longer present. By
pressing the Reset button on the central status indication, you can reset the stored fault.
"Trap Inspect" is indicated on the measuring amplifier by a yellow LED. This permits a
defective steam trap to be identified easily, even in the field.
