Test mode
The Test function can be activated with the jumper X32. This must be plugged to X32 (1–2)
during normal operation, the Test position is 2–3.
The Test function is intended for easy commissioning and service tasks. In this operating
mode, no signals pass through the communication converter (Figure 20). The interfaces
available are looped at the inputs, so that parts of the entire communication path can be
checked.
The DR relay is picked up in Test mode.
For more details about the procedure for putting a protection device into operation with the
communication converter, refer to the device manual of the protection device under the
section "Installation and Commissioning".
