#PCIOMs. Set the number of Programmable Customer Input/Output Modules (PCIOMs) installed in the user interface box. This setting controls the number of input contacts and output relays available in the Input/Output menu.

See “Contacts and Relays” on page 25 to set up the contacts and relays from the display interface.

See the NetworkAIR FM DX 60 Hz Installation manual to connect the contacts and relays to the Main Module.

#Modules in Sys. Indicates the number of Modules in this System. Up to three Modules can be joined together to work as a single System.

Air Filter. Set the type of air filters installed in the Modules of this System to either standard (30- 40%) or high efficiency (65-85%).

Fast Startup. Set the System to bypass the normal start-up sequence and start-up delay the next time power is applied to the System.

Note: The Fast Startup option is not recommended for typical installations.

Airflow. Set the airflow pattern for the Modules in this System.

•Up

•Down

Rej. Method. Indicates the method used for heat rejection by the refrigeration system.

•Air

•Water

•Glycol

Dehum Capacity. The dehumidify mode can be set to use half capacity or full capacity of the cooling coil.

•Half capacity uses one compressor and half of the cooling coil to dehumidify. Rooms with small heat loads should use half capacity to avoid over-cooling while dehumidifying.

•Full capacity uses the entire coil and both compressors.

When the unit is in dehumidification mode the dehumidification solenoid valve on the secondary liquid line is not energized and remains closed. All refrigerant is directed through the expansion valve which feeds three quarters of the cooling coil.

Module Rot. The System rotates the order in which the compressors are engaged to equalize the total number of hours that each compressor runs. Set the number of hours at which to change the order in which the compressors are engaged. A setting of zero indicates that the order in which the compressors are engaged should not be changed.

Refrigerant. Set to the type of refrigerant charge used in the direct expansion refrigeration system..

Suction Pressure Compensation. Allows the System to slow the blowers if the suction pressure gets too high. Use this setting if you are using the FM in a high-density application.

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.
