1. 1

   Measure supply voltage to Pressure Sensor 31 and verify it matches specifications.

2. 2

   Inspect wiring and terminal connections for Pressure Sensor 31 from the sensor to the elevator control input module for damage, corrosion, or loose connections.

3. 3

   Verify the output signal from Pressure Sensor 31 at the input module terminals, comparing against expected values (e.g., 4-20mA, 0-10V, or digital state).

4. 4

   Check the Kone Elevator Control system's configuration parameters related to Pressure Sensor 31 for correct scaling, input type, and alarm thresholds.
