Non-observance can result in death, personal injury or substantial property damage. Only a competent electrician is allowed to carry out the electrical installation. Page Introduction Introduction 3. This is possible due to the modern technology applied both in hardware and software solutions. Functional description 5. Table 5. Standard functions Standard functions are used for logics such as interlocking, alarming and control sequencing.

The use of logic functions is not limited and the functions can be interconnected with protection, control, measurement, condition monitoring and other standard functions. Configuration 5. The standard defines the programming language used for configuration. These parameters can be found in the local menu of the machine terminal.

External parameterization The Relay Setting Tool is used for parameterizing and setting the machine terminals externally. The parameters can be set off-line on a PC and downloaded to the machine terminal over a communication port. The menu structure of the setting tool, including views relating to parameterization and settings, is the same as the menu structure of the machine terminal.

The machine terminal has 9 sensor inputs. A current sensor Rogowski coil or a voltage divider can be connected to each sensor input. Should a matching transformer be used on a channel, no sensor is allowed to be used on the same channel or vice versa. Each analog channel is separately configured with the Relay Configuration Tool.

Both the measuring unit for each analog channel and the type of signal to be measured are to be configured. Scaling the rated values of the protected unit for analog channel A separate scaling factor can be set for each analog channel.

The factors enable differences between the ratings of the protected unit generator, transformer, motor, etc. The setting value 1. Technical data of the measuring devices When the machine terminal is configured, the technical data of the measuring devices is set in separate dialog boxes in the Relay Configuration Tool.

The set values will affect the measurements carried out by the machine terminal. Calculated analog channels The machine terminal includes virtual channels to obtain neutral current and residual voltage when sensors are used. Current sensors and voltage dividers are connected to the machine terminal via coaxial cables and therefore a residual connection of phase currents or an open-delta connection of phase voltages cannot be made.

Filter time of a digital input The filter time eliminates debounces and short disturbances on a digital input. Specifically, the changes to the investigation and testing requirements for Power Conversion Equipment and the resulting impact on ratings for short circuit current SCCR.

This technical note reviews how a modbus backwards compatibility mode allows the drive to emulate a drive. This feature is useful for retrofit situations that have an existing PLC.

VD4 - Installation and service instructions. ID: REV: AA. Engineering Guide. ID: HT The BI value changes on the rising or falling edge of the input. To prevent undesired status changes of the digital input due to switch debouncing, etc.

However, the inputs share a common ground. The value of the Input mode parameter determines which range parameter is used. The Temperature range parameter also defines the sensor type to be used, e. Parameter Values Default Transducer supervision The measuring signal level of each transducer is constantly supervised. The linearization curves can be enabled and disabled with the Linear. To be able to maintain the specified accuracy in spite of aging and varying temperature, the card also includes special hardware to allow self-recalibration on the field.

This recalibration procedure runs continuously, even when no measurements are activated, to ensure that the card is always optimally calibrated. Page Rtd Temperature Vs. RTD temperature vs.

All outputs are galvanically isolated from the supply and enclosure of the machine terminal and from each other. For technical data of the analog outputs, refer to Table 5. The transition of the AO IV state may also generate an event. The output behaviour when the value attribute is outside the defined limits is as follows: Output range Value of AO Self-supervision IRF The machine terminal is provided with an extensive self-supervision system.

See also Table 5. The code should be supplied when overhaul is ordered. The following table gives an overview of the fault origin. No 1MKC The cable is connected to the serial RS port of the PC. Parameter Value Default value Explanation Subnet number System structure The system very often resembles the system in the figure below. Display panel HMI The machine terminal is provided with either a fixed display or an external display module. For more information about the rated input voltages, refer to Table 5.

The time stamp of the first alarm is recorded. Successful acknowledgement clears the time stamp line of the alarm view and the corresponding alarm LED. An event is generated on the rising and falling edge of the ON signal and by acknowledgement. Interlocking The interlocking LED text can be defined in the same manner as for the other alarm channels.

The colour of the interlocking LED is yellow and cannot be changed. The normal LED state is inactive no light. Design description 5. Technical data Table 5. Page Terminal Connections 2.
