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 CC–S
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
CC–S , refer to the device manual of the protection device under the section "Installation and
