IS200EPSMG1AED General electric module

If the system to be measured is a Delta connection, the values are “3 Wire Direct” and “3 Wire Delta / 2 VTs”. The “3 Wire Direct” value should be used for systems that are 600 V or less and directly connected to the PQMII. With external VTs, “3 Wire Delta / 2 VTs” must be selected. The PQMII accepts input voltages from 0 to 600 V AC between any two of the voltage terminals (V1, V2, V3, and Vn). These inputs can be directly connected or supplied via external VTs. External VTs are required for input voltages greater than 600 V AC (lineto-line). When measuring line-to-line quantities using inputs V1, V2 and V3, ensure that the voltage common input Vn is grounded. This input is used as a reference for measuring the voltage inputs. All connections to the PQMII voltage inputs should be connected using HRC fuses rated at 2 amps to ensure adequate interrupting capacity. • VT RATIO: Enter the voltage transformer ratio. All three voltage inputs must be of the same rating. For example, if 4200:120 VTs are used, the VT RATIO should be 4200 / 120 = 35.0:1. This setpoint is not visible if VT WIRING is set to “3 Wire Direct”, “4 Wire Direct”, or “Single Phase Direct”. • VT NOMINAL SECONDARY VOLTAGE: Enter the nominal secondary of the VTs. If the voltage inputs are directly connected, enter the nominal system voltage that will be applied to the PQMII. This setpoint is not visible if the VT WIRING is set to “3 Wire Direct”, “4 Wire Direct”, or “Single Phase Direct”. This value is used to scale an analog output that is assigned to display voltage as a percentage of nominal.

NOMINAL DIRECT INPUT VOLTAGE

 This setpoint is displayed only if VT WIRING is selected as a direct connection. The nominal direct input voltage must be entered in this message. This value will be used to scale an analog output that is assigned to display voltage as a percentage of nominal. • NOMINAL SYSTEM FREQUENCY: Enter the nominal system frequency. The PQMII measures frequency from the Van voltage and adjusts its internal sampling to best fit the measured frequency. If the Van input is unavailable, the PQMII will assume the frequency entered here.

The PQMII has four (4) Analog Outputs configured through four setpoints pages. The ANALOG OUTPUT RANGE setpoint appears in the Analog Output 1 setpoints page only and applies to all four outputs. • ANALOG OUTPUT RANGE: If the T20 option is installed, the Analog Outputs can be configured to operate as 4 to 20 mA current sources or 0 to 20 mA current sources. All four Analog Outputs will operate in the range defined by this setpoint. • ANALOG OUTPUT 1(4) MAIN / ANALOG OUTPUT 1(4) ALT: If the PQMII is used in conjunction with programmable controllers, automated equipment, or a chart recorder, the analog outputs can be used for continuous monitoring. Although parameters can be selected for continuous analog output, all values are available digitally through the communications interface. Applications include using a computer to automatically shed loads as the frequency decreases by monitoring frequency or a chart recorder to plot the loading of a system in a particular process.
