Description
- Control mechanism: Uses a neutral zone or proportional band based on pressure or temperature sensed in LP suction and HP circuits.
- Load balancing: Special algorithm balances compressor run hours for uniform workload distribution.
- Conversion and display: Controllers convert suction and discharge pressures into temperatures for monitoring.
- Front panel display: Provides comprehensive system status info including suction and condenser pressure (temperatures), load status, alarms, and maintenance alerts.
- Alarm system: Each load has its own alarm input capable of stopping it when triggered. Additionally, there are inputs for low and high pressure switches to ensure system safety; activation of these switches halts the system.
- Programming: Controller can be easily programmed at power on via the HOT KEY.
- Connectivity: Controller can connect to X-WEB, a control and monitoring system, through serial TTL output using ModBus RTU protocol.
