Commissioning 5.1 Check proper connection During installation and connection, abide by the relevant standards and regulations and follow the operating manuals for the device. 5.2 Before switching on Before switching on think carefully about these questions: 1. Does the connected supply voltage US correspond to the nameplates information? 2. Is the nominal system voltage of the measuring current transformer not exceeded? 3. Does the measuring current transformer's maximum current corres pond to the nameplate information of the connected device? 5.3 Switching on After switching on, proceed as follows: 1. Connect the supply voltage. 2. Set the bus address/IP address. 3. Set the CT transformer ratio (for each channel). 4. Change the measuring current transformer's counting direction, if required. 5. Set the nominal voltage. 6. Select connection: wye, delta, one-phase-…connection. PEM330-333_D00004_01_M_XXEN/08.2015 33 Commissioning 5.4 System integration and visualisation The universal measuring device PEM333… can be parameterised and queried via Modbus-RTU. For details refer to Chapter 8. Modbus Register Map and to the internet modbus.org. In addition, it can be incorporated into Bender's own BMS (Bender measuring device interface) bus protocol via additional communication modules. This al lows communication with Bender devices (already existing) to realise device parameter setting and visualisation of measuring values and alarms. Examples and information about system integration you will find on our homepage bender.de or you can personally discuss it with Bender service experts (see "Chapter 1. 2 Technical support: Service and support"). 34 PEM330-333_D00004_01_M_XXEN/08.2015 6.

Application/inputs and outputs 7.1 Digital inputs (PEM333… only) The device features two digital inputs that are internally operated with DC 24 V. Digital inputs are typically used for monitoring external states. The switching states of the digital inputs can be read from the LC display or from connected system components. Changes in external states are stored as events in the SOE log in 1 ms resolution. 7.2 Digital outputs (PEM333… only) The device features two digital outputs. Digital outputs are typically used for setpoint trigger, load control or remote control applications. Examples: 1. Available via the buttons on the front panel (see "Chapter 6.9 Setup using the "SETUP" button") 2. Operation via communication interface 3. Control setpoints: Control actions in case of setpoint exceedance 7.3 Display Energy pulsing The two LED pulse outputs are used for kWh and kvarh indication, if the func tion EN PULSE is enabled. The setting can be carried out in the Setup menu us ing the buttons on the front or via the communication interface (PEM333… only). The LEDs flash each time a certain amount of energy is measured (1 kWh resp. 1 kvarh). PEM330-333_D00004_01_M_XXEN/08.2015 59 Application/inputs and outputs In order to determine the actual amount of energy, the flashing frequency can be calculated from the CT ratio and the pulse constant.. Comment:

Pulses per kWh = Pulse constant ratio VT x ratio CT ratio VT x ratio CT = Amount of energy per pulse Pulse constant VT = voltage transformer CT = current transformer

7.4 Digital pulse outputs (PEM333-…P only) The device features two digital pulse outputs for kWh and kvarh, which can be activated via the EN PULSE function. They behave like LED pulse outputs: As soon as a specific amount of energy (1 kWh or 1 kvarh) has been measured, a signal for further processing will be emitted via the outputs. Digital pulse outputs are normally used for accuracy tests. 7.5 Power and energy 7.5.1 Voltage and current phase angles Phase analysis is used to identify the angle relationship between the three phase voltages and currents. 7.5.2 Energy Basic energy parameters include ● Active energy (import and export in kWh) ● Reactive energy (import and export in kvar) ● Apparent energy (Sges in kVAh) The maximum value to be displayed is ± 99,999,999.9. When the maximum value is reached, the energy register will automatically roll over to zero. The energy register can be edited via software (PEM333… only) and the buttons on the front panel, password required. 60 PEM330-333_D00004_01_M_XXEN/08.2015 Application/inputs and outputs 7.5.3 Demand DMD Demand is defined as the approximate average power consumption over a fixed interval. The following values are determined: ● Active power P ● Apparent power S ● Reactive power Q ● I1 ● I2 ● I3 The time specified for measuring can be set using the buttons on the front panel or via the communication interface. The following options are available: 1, 2, 3, 5, 10, 15, 30, 60 minutes During the selected measuring period, the power consumption resp. the im ported power is measured. Then the average demand value is indicated on the display and output via the communication interface. The maximum demand value determined over the whole recording period (peak demand) will be saved and displayed. The peak demand can be reset manually. Setting options see "Chapter 6.10 Setup: Setting possibilities". 7.6 Setpoints (PEM333… only) The device features 6 user programmable control setpoints which provide ex tensive control by allowing a user to initiate an action in response to a specific condition. The alarm symbol at the bottom of the LC display appears if there are any reached/active control setpoints. When the setpoint is reached it will typically result in alarming and fault detection. Setpoints are programmed via the communication interface and have the following setup parameters: 1. Setpoint type: specifies the parameters to be determined and the set point type (limit value exceeded/below limit value). PEM330-333_D00004_01_M_XXEN/08.2015 61 Application/inputs and outputs The following settings are possible: Setpoint type Parameters Values exceeded Phase voltages ULN (x100 V) Line-to-line voltages ULL(x100 V) I (x1000 A) Pges(x1000 kW) Qges(x1000 kvar) Value below limit Phase voltages ULN (x100 V) Line-to-line voltages ULL(x100 V) Power factor λ (×1000) 2. Setpoint limit: Specifies the value that the setpoint parameter must go below or exceed for the setpoint to become active. Returns to normal condition in case of: ● the limit value is exceeded 0.95 x setpoint limit ● the value is below the limit value 1.05 x setpoint limit For P, Q and λ, also negative values can be entered as setpoint limits. 3. Setpoint delay: Specifies the minimum duration ● which the setpoint condition must be met before the setpoint beco mes active or ● which the setpoint return condition must be met before the setpoint becomes inactive. An event will be generated and stored in the SOE Log for any setpoint status changes. The range of the setpoint delay is between 0 and 9,999 seconds. 4. Setpoint trigger: Specifies what action the setpoint will take when it becomes active. This action includes "No Trigger" and "Trigger DOx". 62 PEM330-333_D00004_01_M_XXEN/08.2015 Application/inputs and outputs 7.7 Event log (SOE log) The device can store up to 32 events. If there are more than 32 events, the newest event will replace the oldest event on a first-in-first-out basis: The 33rd event overwrites the first entry, the 34th the second etc. Possible events: ● Failure supply voltage ● Setpoint status change ● Relay actions ● Digital input status changes ● Setup changes Each event record includes the event classification, the relevant parameter values and a timestamp of 1 ms resolution. All event records can also be retrieved via communication interface (PEM333… only). The event log can be cleared using the buttons on the front panel or via com munication interface (PEM333… only). 7.8 Power Quality 7.8.1 Total harmonic distortion The device provides an analysis of the total harmonic distortion. All parame ters can be read from the display or are available via communication interface (PEM333… only). The following parameters are provided:
