The AALBORG YORK 1606-002 UNISAB II Mission Power Panel is a sophisticated microprocessor-based controller designed for the comprehensive management of industrial cooling and compressor systems. As a central interface for the UNISAB II platform, it monitors critical parameters such as suction pressure, discharge temperature, and oil differential pressure to ensure optimal thermodynamic efficiency. This 0319-2002 unit acts as both a protection device and an operational sequencer, preventing mechanical failure through advanced limit sensing while providing a user-friendly diagnostic portal for maritime and land-based refrigeration technicians.
Key Differences from Similar Models
The 1606-002 (0319-2002) model is specifically optimized for Mission Power configurations, distinguishing it from the standard UNISAB II “S” or “D” variants which may lack the specific power management sub-routines found in this version. Unlike the older 1606-001 series, the 0319-2002 features a more resilient power supply board (PSB) that is less prone to “blackout” resets during heavy motor starts on weak electrical grids. Additionally, this specific revision includes updated EPROM/Flash memory capacity to support more complex PID loop tuning and multi-compressor lead-lag logic that is absent in the basic UNISAB I legacy controllers.
Operational Tips
- Backup Battery Replacement: The internal memory is maintained by a lithium battery; if the panel loses its “Real Time Clock” or configuration after a power cycle, the battery likely requires replacement to prevent data loss.
- Pressure Transducer Shielding: To avoid “ghost” alarms or erratic pressure readings, ensure that the analog input cables for sensors are shielded and routed away from high-voltage motor cables to minimize EMI.
- Contrast Adjustment: If the LCD screen appears blank or dark, use the potentiometer on the rear of the display board to adjust the contrast; temperature fluctuations in engine rooms can often cause the liquid crystal to fade.
- Configuration Logic: When installing a new 1606-002, ensure the “Comp Type” (Screw vs Reciprocating) is correctly set in the service menu. Using the wrong compressor profile can lead to incorrect oil pressure trip points and potential mechanical damage.
