Action Required

 

 

Supply Humidity High

• Verify that the suction pressure is not below 58 psig (400 kPa).

 

• Ensure that the alarm delay is not set too low. The delay should be long

 

enough to allow the Module to control the humitity after start-up.

 

• Ensure the alarm threshold for the humidity of the supply air is set above the

 

humidify and dehumidify setpoints.

 

• Verify that there is proper airflow through the Module. (Check the pressure

 

drop across the evaporator coil.)

 

• Check the capacity output of the humidifier and reduce it if required.

 

• Ensure that there is a proper vapor barrier within the conditioned space.

 

• Verify that the Module is configured and equipped for the dehumidify mode.

 

• Ensure the dehumidify mode is enabled.

 

• Ensure the dehumidify mode is not disabled because of an active custome

 

input mapped to a nonessential lockout.

 

 

Supply Humidity Low

• Ensure the alarm delay is not set too low. The delay should be long enough to

 

allow the Module to control the humidity after start-up.

 

• Ensure the alarm threshold for the humidity of the supply air is set below the

 

humidify and dehumidify setpoints.

 

• Check the capacity output of the humidifier and increase it if required.

 

• Ensure there is a proper vapor barrier within the conditioned space.

 

• Verify the Module is configured and equipped for the humidify mode.

 

• Ensure the jumidify mode is enabled.

 

• Ensure the humidify mode is not disabled because of an active customer

 

input mapped to a nonessential lockout.

 

 

Supply Sensor Fail

• Verify that there is a proper CAN connection between the sensors and the

 

user interface box.

 

• Check the connections of the 25 pin serial communication cable from the

 

main controller board to the customer interface box.

 

• Replace the sensor assembly.

 

 

Supply Temperature High

• Ensure that the alarm delay is not set too low. The delay should be long

 

enough to allow the Module to control the temperature after start-up.

 

• Verify that the supply air temperature alarm threshold is set above the cool

 

and reheat setpoints.

 

• Verify that there is proper airflow through the Module (check the pressure

 

drop across the evaporator coil).

 

• Ensure that the cool mode is enabled.

 

• Ensure that the cool mode is not disabled because of an active customer input

 

mapped to nonessential lockout.

 

 

Supply Temperature Low

• Ensure that the alarm delay is not set too low. The delay should be long

 

enough to allow the Module to control the temperature after start-up.

 

• Verify that the Module is configured and equipped for the reheat mode.

 

• Ensure that the supply air temperature alarm threshold is set below the reheat

 

and cool setpoints.

 

• Ensure that the reheat mode is enabled.

 

• Ensure that the reheat mode is not disabled because of an active customer

 

input mapped to nonessential lockout.

 

• Verify that there is proper airflow through the Module (check the pressure

 

drop across the evaporator coil).

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.
