External Fault (TRIP-SET)

What does EEr mean?

An external disturbance has been detected, activating a digital signal assigned to the TRIP-SET function (DCTRL1-TRIP-SET). This typically results from a LOW level at the signal source for this function, causing the controller to inhibit. Ignoring this can lead to system shutdown and operational delays.

• External safety device (e.g., emergency stop, limit switch, thermal relay) connected to DCTRL1-TRIP-SET has opened.
• Break or loose connection in the wiring to the digital input configured as DCTRL1-TRIP-SET.
• Faulty external sensor or auxiliary contact providing a LOW level signal to the DCTRL1-TRIP-SET input.
• Incorrect parameter assignment for DCTRL1-TRIP-SET, causing unintended tripping.
• Electromagnetic interference (EMI) causing a momentary drop of the signal level on the digital input.

Click steps to track your progress.

1. 1

   1. Identify the external device connected to the digital input assigned to DCTRL1-TRIP-SET (e.g., C0020 for DI1, C0021 for DI2).

2. 2

   2. Measure the voltage level at the specific digital input terminal configured as DCTRL1-TRIP-SET; it should be HIGH (e.g., 24VDC) when no fault is present.

3. 3

   3. Inspect the wiring to the DCTRL1-TRIP-SET input for continuity, loose connections, or damage.

4. 4

   4. Verify the operational status of the external safety device or sensor connected to this input.

5. 5

   5. Check drive parameter settings for the assigned digital input to ensure DCTRL1-TRIP-SET is the intended function.
