Functions
◦ Extension rack(s)
• Network
◦ PICUS
◦ Modbus
• Controllers connected in a ring for communication redundancy:
◦ If there is a failure: Communication path changed within 100 milliseconds.
• Authentication (other equipment cannot disrupt communication)
• Password protection
◦ Customisable permission levels
Modbus
• Supports multiple Modbus protocols
◦ Standard protocol: Modbus TCP/IP
◦ Supports use and creation of custom protocols
◦ Import and export Modbus protocols
• Convert data units and scaling
• Configure Modbus server settings
Breaker control
• Synchronisation and breaker closing
◦ Dynamic synchronisation: With slip frequency, for fast load acceptance
◦ Static synchronisation: Phases match kept within a phase window
• De-load before opening
• Automatic synchronisation and de-loading
• Operator-initiated synchronisation and de-loading possible
• Breaker types (with configurable parameters)
◦ Pulse breaker, Compact breaker, Continuous breaker
• Breaker position detection and alarms
Advanced blackout
prevention (optional)
• Run with a closed bus tie breaker during critical operations
• If a genset governor or AVR fails, the bus tie breaker trips and disconnects the genset
Redundancy
• True multi-master control
• Busbar can have a ring connection
• DEIF network ring connection
• Internal communication ring connection
• Controller commands and operation using the display unit, inputs, PICUS, and/or Modbus
• Redundant breaker feedback on bus tie breakers and externally controlled breakers
Additional hardware/
software features
• Hardware/software features: Power supply voltage measurement diode offset
• Relay configuration (function, coil state)
• Analogue input sensor failure (below and above range)
• Analogue input pre-configured curves, plus up to 20 customisable curves
• Analogue output pre-configured curves, plus up to 20 customisable curves
• Display unit lamp test
