For fail-safe transmission, the current signals are converted into opti- cal signals and transferred via fiber-optic cables. The monitoring system carries out the following checks: 1. After the by-pass switch has opened and before the vacuum interrupter opens, there must be a current signal. 2. Once the vacuum interrupter opens, there must be no current signal present. If one is present, the monitoring system generates an alarm signal. The monitoring system is also fitted with self-monitoring, which checks the in- ternal circuits. At the input, the electronics are protected by a Zener diode and an interchangeable fuse. 10771253/01 EN Product description 35 4.5.3.2.3 Displays and controls Figure 26: Monitoring system (VIM) displays and controls 1 RESET key (red) 2 TEST key (green) 3 Power LED (green) 4 1 yellow and 1 red LED per phase for signaling errors The following monitoring system (VIM) displays and controls are located in the motor-drive unit control cabinet: – The green TEST key is used to check the internal circuitry of the monitoring system.
