Technical Guide cation and wired into the correct terminals on the WMVAV controller.
Be sure any expansion boards connected to the WMVAV controller are also correctly wired just as you did for the WMVAV controller.
After all the above wiring checks are complete, apply power to the
WMVAV controller and all expansion boards connected to it.
COMM LED should flicker approximately once every second to indicate communications are occurring. If the LEDs are behaving as indicated, proceed to the next step. If the LEDs fail to light or do not behave as indicated, please proceed to the troubleshooting section of this manual to diagnose and correct the problem before proceeding with the start-up process.
Initialization:
Upon applying power to the WMVAV controller the following should occur:
On system powerup a 30 second start-up delay is performed where all default setpoints are initialized, LED’s are initialized and all outputs are turned off.
When power is first applied, LED2 is turned off for 5 seconds. At this time the LED will “blink” to indicate the setting of the address switch and then extinguish for another 5 seconds. The LED will now “blink” for a 30 second start-up delay to protect the fan and other components from short cycling during intermittent power conditions. If all inputs are operating correctly it will blink once every ten seconds.
Programming The Controller
The next step is programming the controller for your specific requirements. In order to configure and program the WMVAV controller you must have a central operators interface or a personal computer with the
Prism computer front end software installed. Two different central operators interfaces are available for programming of the WMVAV controller. You may use either the Modular Service Tool or the Modular Sys-
tem Manager to access the status and setpoints of any WMVAV controller on your communications loop. See the Modular Service Tool and
System Manager Programming guide for WMVAV controller programming. If you are going to use a personal computer and the Prism computer front end software, please see the WattMaster Prism Programming Manual. No matter which operators interface you use, it is recommended that you proceed with the programming and setup of the controller in the order that follows:
The PWR LED should glow continuously. If this is a stand alone or interconnected system, The COMM LED should also glow continuously after its initial start-up routine. If this is a networked system, The
1.) Configure The Controller For Your Application
2.) Program The Controller Setpoints.
3.) Program The Controller Operation Schedules.
4.) Set The Controller Current Time And Date.
5.) Review Controller Status Screens To Verify System
