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
