(n.c.). In addition, the alarm category "Err" has to be assigned to the selected alarm relay in the menu out/r1 or r2. If these conditions cannot be met, periodic inspection of the VMR420 is required! 3.2.6 Time delays The times described below delay the indication of alarms via LEDs and relays. -
Page 18: Delay On Release
3.2.10 Measuring range selection in relation to the response time The VMR420 provides several measuring ranges. Depending on the setting of the response value for overvoltage, the device selects the optimum measu- ring range automatically. If the measured voltage exceeds the set response... -
Page 19: Erasable History Memory
Function 3.2.14 Erasable history memory The first alarm value to occur is written to this memory. Subsequent alarms do not overwrite this "old" value. The memory can be erased via the menu HiS with Clr. 3.2.15 Alarm LEDs show which relay is in the alarm state Once the menu LEd has been activated, the alarm LED AL1 indicates that K1 is in the alarm state. - Page 20 Function The fault for K1 shown in the time diagram below, by way of example, has star- ted during the S.AL phase: S.AL The fault for K1 shown in the time diagram below, by way of example, started when the S.AL phase has elapsed: S.AL VMR420_D00370_00_M_XXEN/07.2018...
