  • Page 5: General Information

    502 069 02 General information. The PD 3260 Power Monitor is a member of the 3000 series of modules from PROCES-DATA. It provides a three-phase Power Line Monitor and Generator Switch Controller interface to the P-NET Fieldbus EN50170 Vol 1.

  • Page 6: Features

    502 069 02 Features. Power Monitor Channel with three-phase current and voltage inputs. Generator Switch Channel with tachometer and voltage inputs. Thyristor Switch Channel with six modulated outputs for a three-phase thyristor switch. 8 Digital I/O Channels with automatic output functions. Output current measurement and overload protection.
  • Page 7 502 069 02 Digital I/O Channels: Various automatic functions can be selected within each digital channel, such as automatic feedback control (single, as well as double), one-shot output and pulse output. This reduces such basic operations having to be performed at a remote central control point. The output current (Sink), is measured continuously on each channel, and can be read as a value in Amps.

  • Page 9: Connections

    502 069 02 Connections. The PD 3260 Power Monitor is physically designed as a black box, having two 14 pin connectors with screw terminals. The connectors are removable and equipped with a key pin, to avoid reversed connections. Connection identities are printed on the top of the module.

  • Page 10: Memory Types

    502 069 02 Memory types. The PD 3260 stores data in different types of memory, depending on the value of a control variable following a reset or a power failure, and the state of write protection. Some variables are stored in both non-volatile and volatile memory. The state of the module's WriteEnable register, determines whether the contents are changed in both types of memory, or only in the volatile type.
  • Page 11 502 069 02 Read Write, Protected BackUp Write RAM InitEEPROM The variable is stored in both RAM and EEPROM. After a reset, the variable is copied from EEPROM into RAM. When the variable is changed via P-NET, the value is changed in RAM. If WriteEnable is TRUE, the value is changed in both RAM and EEPROM when the variable is modified via P-NET.

  • Page 43: Connections To The Power Monitor Channel

    502 069 02 Connections to the Power Monitor Channel. The Power Monitor Channel has two basic connection schemes, depending on the channel configuration. One is for three-phase systems and one is for single-phase systems. Three-phase system without neutral (ChConfig.Functions = $10). In a three-phase system, the total power of a three-phase power consumer can be measured as the sum of the readouts of three power meters, each measuring a phase voltage and a line current.

The current inputs are high precision factory calibrated. Three-phase system with neutral (ChConfig.Functions = $20): In a single-phase mode, the module may be used to monitor up to three power consuming devices on the same, or different phases, by using the current and voltage inputs separately.
