ZASF – Optional VAV Accessories for use with ZN Line Modules
Optional VAV Accessories for use with ZN Line modules
The ZASF is part of a family of control modules designed specifically for VAV terminal box applications. It is designed to be used with the ZN341v+ and ZN141v+. It mounts directly on the secondary VAV damper shaft and provides an integral actuator and a second integrated flow sensor for damper positioning and air-flow sensing in dual duct or tracking systems.
In many industries, mechanical systems serve as the backbone
Thermal data collected with a thermal imaging camera can be
an invaluable source of complimentary information to vibration
studies in mechanical equipment monitoring.
Mechanical systems will heat up if there is a misalignment at
some point in the system.
Conveyor belts are a good example. If a roller is worn out, it will
clearly show in the thermal image so that it can be replaced.
Typically, when mechanical components become worn and less
efficient, the heat dissipated will increase. Consequently, the
temperature of faulty equipment or systems will increase rapidly
By periodically comparing readings from a thermal imaging
camera with a machine’s temperature signature under normal
operating conditions, you can detect a multitude of different

This thermal image shows an electric engine under normal operation.
Motors can also be inspected with a thermal imaging camera.
Motor failures like brush contact-wear and armature shorts
typically produce excess heat prior to failure but remain
undetected with vibration analysis, since it often causes little
to no extra vibration. Thermal imaging gives a full overview and
allows you to compare the temperature of different motors.
Other mechanical systems monitored with thermal imaging
cameras include couplings, gearboxes, bearings, pumps,
compressors, belts, blowers and conveyor systems.
Examples of mechanical faults that can be detected with thermal
• Lubrication issues
• Overheated motors
• Suspect rollers
• Overloaded pumps
• Overheated motor axles
• Hot bearings
These and other issues can be spotted at an early stage with
a thermal imaging camera. This will help to prevent costly
damages and to ensure the continuity of production.

The BTU07 is a full featured and low cost BTU meter with Modbus over RS485 capability developed specifically for sub metering applications. The DFSR737A is unique among BTU meters by having the BTU calculator separate from the flow sensor, which allows the flow meter to be installed where it is needed, but with the BTU calculator and display installed anywhere it is convenient for tenant reading. The BTU07 comes as a set together with the flow and temperature sensors.
Digital Device Network for Lighting Control
Automated Logic’s Digi-Touch® Network dramatically reduces installation and wiring costs of field input devices, while increasing functionality of lighting switches. The Digi-Touch Network allows addressable Digi-Touch wall switches and Digi-Touch Input Modules to communicate with the LC series of Lighting Control Panels.
Powerful Microprocessor-Based Lighting Control Panels
Automated Logic’s Lighting Control (LC) line brings the power and simplicity of WebCTRL® to your building’s lighting systems. The LC line utilizes advanced microprocessors to provide superior lighting control, while delivering the rapid response required by lighting applications.
Automated Logic’s ZN551 provides unprecedented power and flexibility through fully programmable networked controllers. The ZN551 controllers connect to the Building Automation System (BAS) network using BACnet over ARCNET 156 kbps or MS/TP. The ZN551 supports a line of RS room sensors using Rnet port
High Speed Ethernet Router
The LGR is an extremely powerful, high-speed device router that can connect hundreds of control modules to a BACnet/IP backbone. Support for BACnet/IP, BACnet over Ethernet, ARCNET 156kbps, MS/TP, and BACnet PTP communications are standard. Optional protocol translator packages and a wide range of communication ports allow the LGR to also serve as a gateway to a wide range of open and proprietary networks. Fully programmable, the LGR can also execute complex control strategies for high level system integration.
A Tool for Sustainable Building Operations
Automated Logic’s EnergyReports™ application is an incredibly flexible, easy-to-use reporting tool that gives facility managers the power to produce a wide variety of reports showing a building’s energy consumption. Using dynamic and animated color graphs, EnergyReports allows users to compare energy consumption or demand over different periods with simple drop-down menus and calendar control options. A click of the mouse enables users to normalize consumption data, convert the data to cost or carbon dioxide emissions, and change engineering units on the fly. This gives facility managers a powerful tool to minimize energy consumption, maximize comfort, and achieve sustainable building operations
Balancing Efficiency with Comfort
WebCTRL Environmental Index – Balancing Efficiency With Comfort
As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort.
Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.
WebCTRL Powerful and Intuitive Front End For Building Control
Automated Logic has long been known for its intuitive, powerful front-end building control software. In fact, ALC pioneered graphical programming in the industry. With our graphical user interface, users have such features as hierarchical scheduling, thermographic color floor plans, trending, alarm management, and reporting. And with WebCTRL®, our web-based building automation system, all of these features are available through a standard web browser – without any special software or plug-ins.
Introduction To Building Management Systems
A BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.
Systems linked to a BMS typically represent 40% of a building\\\’s energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.
As well as controlling the building\\\’s internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.
Functions of Building Management Systems
The three basic functions of a central, computer-controlled BMS are:
the building’s facilities, mechanical, and electrical equipment for comfort, safety, and efficiency.
A BMS normally comprises of:
