Installation and wiring method of DT1 series voltage monitor

Installation and wiring method of DT1 series voltage monitor

  1. Installation

  For the trough-mounted DT1/C series voltage monitor, after opening the 150+1×70+1 hole, push the meter in, and use the dial to install the fixed rod on both sides.

   Note: Since online communication may be required, it is recommended to consider the space occupied by the DT1/C lead wires and communication interfaces when designing the power distribution cabinet. Please leave a space of 60-80mm.

  2. Wiring

   In the wiring board, pins 1 and 2 of the upper row of SP are connected to 1 voltage signal input; pins 4 and 5 of SP are connected to 2 voltage signal inputs; pins 6 and 7 of SP are connected to 3 voltage signal inputs. The 2 and 3 pins in the lower row of XP are connected to Ug AC power supply, where Ug=AC100V or 220V or 380V, subject to the actual standard operating power supply voltage on the rear panel of the meter. The power circuit fuse (0.25A) has been installed in the table, and there is no fuse on the wiring board.

  Only when the working power supply voltage is the same as the signal voltage level of No. 1 signal, the signal voltage of No. 1 can also be used as the working power supply (that is, the upper row SP1 and pin 2 are used as the working power input pins), subject to the actual rear panel instructions.

   3. Introduction of 1 minute voltage over limit normally open relay contact output

   According to user requirements, our company can provide Shunyang brand DT1/C statistical voltage monitor with 1-minute voltage over-limit relay contact output. Each channel has 1 minute voltage over-limit output relay contacts, and the capacity is 3A125VAC or 28VDC, the working power of the monitor is generally AC220V. That is, when the voltage average value exceeds the upper limit or the lower limit 1 minute before the measured voltage of the 1st, 2nd, or 3rd road, the corresponding alarm relay is closed to make the corresponding contact on; when the measured voltage is 1 minute before When the voltage average value is qualified (that is, when it does not exceed the limit), the corresponding alarm relay is released and the corresponding contact is disconnected. The location of each contact is shown in the figure:
