Capture time Capture time Capture time Capture time Time base Time base Time base Scenario “Pulse before time base, within the capture time”: · Perform value calculation now. · The time is set to 0 (new relative zero point). · Delete summed intermediate values.
UMG 96-PQ-L 13.16.3 Synchronization priority An external synchronization takes place according to different priorities: · Priority 1: Modbus synchronization For this, set the “Enable flag” (addr.: 822) using the Modbus tool or select the “Synchronization via Modbus” option in the GridVis® software in the drag indicator configuration area. · Priority 2: Synchronization via digital input 3 For this, set the Modbus parameter “FUNC_ SYNC_RECORD” (addr.
www.janitza.de UMG 96-PQ-L 13.16.4 Drag indicator - Measurement device displays As already described in section “13.16 Drag indicator function”, the drag indicator function shows the 3 highest average values of value types over a defined period (time base). The drag indicators of the respective measured value types can be called up on the measurement device display under Menu > Drag indicator.
UMG 96-PQ-L 13.16.5 Delete drag indicator In each drag indicator display of the device - current, active and apparent power - a dialog box for deleting the drag indicator values appears when button 6 is pressed: Fig. Dialog box for deleting the drag indicator values INFORMATION The deletion of current, active power or apparent power drag indicator values of one phase also causes the deletion of the drag indicator values for the other phases of the respective category.
www.janitza.de 13.17 Recordings The standard setting of the measurement device includes 2 recording profiles that you can adapt or expand in the GridVis® software. · The smallest time base for recordings is 1 minute. · A maximum of 4 recordings with 29 measured values each is possible. If min. and max. values are defined as well, the number is reduced to 19 or 14 values respectively.
UMG 96-PQ-L 13.18 Tariff switching The recording of electrical energy values (active, reactive and apparent energy) is done via internal meters for two tariffs each. www.janitza.de INFORMATION Configure tariff switching using the GridVis® software! Switching between the tariffs (HT/LT) is supported by: · Modbus, · digital input 1 (see section “Digital inputs”) or · the weekly timer (see section “Timer switch output”) Fig.
