Path: Main > Setup > System # > System Config > System Delays

The System Delays protect the Modules in the System from excessive wear and damage and keep the modes (cooling, reheat, and dehumidify) from working against each other.

Comp Min ON. The delay begins when the compressor engages and then prevents the compressor from disengaging until the delay has expired. It protects the compressors from rapidly cycling between on and off and pushing all of their lubricating oil out into the refrigerant line.

Caution: Reducing the Comp Min ON delay can shorten the compressor life by causing excessive wear and damage.

Comp Min OFF. The delay begins when the compressor disengages and then prevents the compressor from engaging until the delay has expired. It protects the compressors from rapidly cycling between on and off and pushing all of their lubricating oil out into the refrigerant line.

Caution: Reducing the Comp Min OFFdelay can shorten the compressor life by causing excessive wear and damage.

Cndsr Vlv Dly. The condenser fluid valve close delay begins when the compressors disengage, and then keeps coolant flowing through the heat exchanger until the delay expires. Once the delay expires, the condenser fluid valve closes.

Intrstg Dly. The interstage delay begins when the first compressor (stage 1) in a Module engages. It prevents a second compressor (stage 2) in a System from engaging until the delay has expired.

Start-up Dly. The start-up delay begins when the System is started and initialized. The System cannot begin operation until this delay has expired. Use the start-up delay to restart equipment sequentially in your room after a power loss.

Mode Dly. The start-up delay begins when the blowers start. It allows the sensors to obtain an accurate reading of the room conditions and it allows the System to check for major alarms before engaging environmental control functions.

Communication Loss Shutdown Delay. Set the communication loss shutdown delay. The delay begins when an Expansion Module loses communication with the Main Module of a System. If communication is not restored before the delay expires, the Expansion Module will shut down. Set the delay for up to twenty-four hours, or set the Expansion Modules to continue operating if communication with the Main Module is lost by selecting Disabled.

DX, FM specifications

The American Power Conversion (APC) DX,FM series represents a cutting-edge solution designed for critical power management and uninterruptible power supply (UPS) applications. Aimed at businesses and data centers that require robust power protection, this series balances high-performance capabilities with advanced technology features.

One of the key distinguishing features of the DX,FM series is its modular design. This allows users to scale their UPS system according to their needs, making it suitable for a variety of environments. Whether you're managing a small server room or a large data center, the modular architecture ensures that you can add or remove capacity with ease. This flexibility not only optimizes initial investments but also supports future growth seamlessly.

The series employs advanced battery technology, which extends battery life and enhances overall performance. With intelligent battery management systems, the DX,FM ensures that battery health is monitored in real-time, preventing premature failures and unnecessary replacements. This leads to reduced maintenance costs and maximizes uptime.

Additionally, the DX,FM series features innovative cooling solutions that enhance performance in high-density situations. Efficient thermal management reduces the risk of overheating, keeping valuable equipment operating optimally. This is particularly crucial in data centers where heat generated by servers can create potential disruptions.

Another significant characteristic of the DX,FM series is its sophisticated monitoring and management capabilities. Integrated with state-of-the-art software, users can gain remote access to their UPS units, enabling real-time tracking of performance metrics. This remote monitoring capability allows administrators to proactively manage power usage and ensure that systems are operating within safe parameters.

Furthermore, the DX,FM series is designed with a high level of redundancy. This built-in reliability feature ensures that if one unit fails, others can seamlessly take over, maintaining power supply continuity. This is critical for mission-critical environments where power outages could result in substantial financial losses or data loss.

In summary, the American Power Conversion DX,FM series incorporates modularity, advanced battery technology, effective cooling solutions, and sophisticated monitoring features to deliver an ideal power management solution for various organizations. Its design prioritizes flexibility, reliability, and efficiency, making it an essential investment for any business looking to safeguard its operations against power disruptions.
