External alarm 1

Was bedeutet A07850 ?

The BICO signal for 'external alarm 1' was triggered, indicating that the predefined condition for this alarm has been met. This is a user-configurable alarm tied to an external event, sensor, or logic input. The specific cause is defined by parameter p2112.

• Input signal connected to parameter P2100 (External alarm 1 trigger) transitioned from 0 to 1, indicating a tripped safety interlock or sensor.
• A process limit switch (e.g., high-level sensor, over-pressure switch) wired to a digital input, which is mapped to P2100.
• A PLC output controlling an external warning condition, mapped to the drive's digital input and subsequently linked via BICO to P2100.
• An over-temperature switch on an external motor or bearing, wired to the drive's digital input to trigger the alarm.

1. 1

   1. Identify the digital input (e.g., DI0, DI1) that is BICO-connected to parameter P2100 (External alarm 1 trigger).

2. 2

   2. Monitor the status of the identified digital input using parameter r0722[x] (e.g., r0722[0] for DI0) to verify its current state.

3. 3

   3. Trace the physical wiring from the identified digital input back to its source (e.g., limit switch, sensor, PLC output).

4. 4

   4. Inspect the external sensor or switch for its activated state; for example, check if a pressure switch has exceeded its setpoint.

5. 5

   5. Verify the logic and configuration of the external device causing the alarm, ensuring its operating limits are appropriate for the application.
