The instrument detects changes in the zero point voltage in an unearthed high voltage network, which is caused by insulation faults. The voltage is normally delivered via a step-down transformer. A green LED indicates that the auxiliary voltage is connected to KPV14x15. The start of the monitoring / measuring function is delayed when the auxiliary voltage is switched on (standard 2 second delay) to avoid a false alarm during start-up. The type of scale depends on which voltage range is to be monitored and can, when ordering, be adapted to the desired measuring range. The LEDs on the scale show the status and give the following message: • ALARM • WARNING • NORMAL The standard variant KPV14E15 has no analog output. KPV14F15 has an isolated analog output signal that is proportional to the meter indication. The three switching relay outputs are configured for Warning (R2), Alarm (R1) and Status (R3). Trip levels and time delays can be set on the unit. The status relay is "fail-safe" and works when either R1 or R2 are tripped. The function of the status relay is inverted (fail-safe) and is activated under normal conditions. The red LEDs flash immediately (approx. 1 flash per second) when set levels pass a trip level. The LED changes function and the relay changes position after the preset delay. If a trip level is missed during the delay interval, the timer will be reset automatically. KPV14 is delivered as standard with automatic reset.
