GCM/LCM Programming (NW8K302)
Course Description 
This course covers all the aspects for an operator using the SIGNAL computer and the NETWORK 8000 controllers. It covers the architecture and overviews the functions of each device in the NETWORK 8000. The operator will be given a broad overview of block programming, specifically referring to the MZ II and the GCM/LCM. The operator will learn how to access each device and examine the existing block programs. This knowledge will allow the operator to make SIGNAL a more useful tool. The course also covers basic procedures for navigating through the NETWORK 8000 SIGNAL control panels, making changes and performing overrides from a monitor screen, adding points through the Project Manager, uploading and downloading databases, setting up an alarm and remote trend, adding users, handling exceptions and alarms, running the Calendar program, creating a new control panel, and graphics creation and modification. For more information, review the course objectives as to the specifics of what is or is not taught. Presentation and lab exercise times are evenly divided. Students work in pairs at a training station. At the Training Center, equipment at each station includes a GCM, LCM, MZ II, MF II, PEM and MicroNet 2000.

Intended Audience

The NETWORK 8000 SIGNAL Basic Operations course benefits building operating personnel who are new to the NW8000 devices and SIGNAL but are responsible for the day-to-day interaction with the pre-programmed NETWORK 8000 system.

HVAC100 or HVAC Controls Introduction Self-Study

Course Objectives

Pre-course Objectives
Course #NW8K201 pre-course material's goal is to provide students with a basic understanding of HVAC so as to reduce class time spent on topics other than system operations. Following pre-course studies students should be able to:

  • Explain or define the following HVAC terms: setpoint, control point, offset, throttling range, differential, action, reset, primary sensor, secondary sensor, reset schedule, 2-position control, floating control, proportional control, PI control, analog and digital.
  • Explain the function and basic operation of the following Control System equipment: sensor, controller, controlled device, normally open and normally closed valves and dampers, steam converters, chillers, cooling towers, pumps, boilers, air handling units (AHU).
  • Explain the functions of the following computer and NW8000 equipment and terms
  • Explain the concepts of the following energy management schemes: timed programmed commands, Duty Cycle, Optimum Start/Stop, Electric Demand Limiting, Enthalpy Optimization, Night Purge Cycle.
  •  Demonstrate a basic understanding as to what is meant by a "sequence of operation" for HVAC equipment.
Course Objectives
Upon completion of the course, the student should be able to:

  • Describe the functions of the NW8000 equipment to include GCMs, LCMs, MF IIs and MZ IIs. 
  • Identify the communication buses in NW8000 architecture, including the LAN, ASD, and LCM bus.
  • List the programming I/O and communication capabilities of the LCMs, GCMs, MZ IIs and MF IIs.
  • Address the devices in the NW8000 system.
  • Identify the communications lights, address switches and wiring terminals on the NW8000 devices.
  • Give examples of AI's, AOs, DIs and DOs.
  • List the three types of block attributes.
  • Identify and define the three parts of a block address for a GCM/LCM in terms of Nxx:Gxx:Lxx, Block Type, Block Name, and Attribute.
  • Define block programming and explain the overall functions and differences of the key blocks found in the GCM/LCMs and the MZ IIs.
  • Explain how the eight input priorities are used in AO and DO blocks. In addition, the student will show how ONDV and OFFDV attributes are used with the IPRs.
  • Logon and Logoff any NW8000 Controller.
  • Login and Logout of the SIGNAL Interface Program on a personal computer.
  • Use, navigate and view dynamic graphics found under the Monitor Screens button.
  • Explain pyramid architecture of the Project Manager button to include the project, the site, the gateway, the panel and the points.
  • Change values such as setpoints, throttling ranges, differentials and occupied times at the NW8000 local area controllers (terminal mode and PSI)
  • Change any input or output value that appears on the SIGNAL monitor screen.
  • Perform overrides and clear overrides on NW8000 local area controllers, perform timed overrides and clear overrides using SIGNAL.
  • Demonstrate the ability to respond to alarms and exceptions and generate a report for each area.
  • Interpret and display reports on trended information, interpret historical and real time graphs.
  • Display the ability to modify and override schedules using the Calendar button.
NOTE: This is a basic operator course and does not cover the following:
  • The #NW8K201 course does not cover sales information comparing NETWORK 8000 SIGNAL other manufactures products, nor other products offered by Invensys, such as HOST, UltiVist or DMS.
  • The #NW8K201 course does not cover installation and details of wiring, nor the details of components such as actuator, sensor, valves, dampers, etc.
  • The #NW8K201 course does not cover set-up, graphic generation, nor programming of the system.
  • The #NW8K201 course is not taught using the customer's equipment or database, nor will a customer's equipment, such as a modem, be connected to the training equipment. While this course does address situations and concerns which are typical to most buildings, specific problems or concerns are directed to the local office.
