OFFLINE DIAGNOSTICS & TROUBLESHOOTING

(REFER TO FIG 48 & 49)

The problems that could be encountered in the Control Center are in the following categories:

•Keypad

•Display

•Serial Input/Output (I/O)

•Digital Input/Output (I/O)

•Analog Inputs

There is a Diagnostic and associated Troubleshooting procedure for each category. They are described on the following pages. The offline diagnostics are accessed from the Diagnostics Main Screen, which is entered using the procedure below. If there is a Remote Control Center problem, determine the category of the problem. Then perform the applicable Diagnostic. If the Diagnostic reveals a malfunction, perform the Troubleshooting procedure to locate the defective component.

There are several documents that must be referred to while performing the Diagnostics and Troubleshooting procedures. Each procedure references the Section and figures of this book that describe the operation of the component being tested.

The Offline diagnostic screens are only available when the panel is powered on (or rebooted) with the Diagnostics Enable dip switch in the Enabled position. When in this mode all normal RCC functions are disabled. If the Diagnostics Enable dip switch is placed in the Disabled position while the panel is in the Offline Diagnostics mode, the Diagnostics task will cause the panel to reboot into the online diagnostics mode.

COM 1 J2 - RS-232.PrinterCOM 1 is connected directly to the Micro. COM 2 through 5 are connected directly to the UART Universal Asynchronous Receive Transmit. The UART converts the parallel data to serial form for transmission to the peripheral device and converts the incoming serial data to parallel form for use by the Micro. It also generates and processes control signals for the Modem communications DTR, CTS, DSR, RTS. Under Program control, the Micro instructs the UART of the desired data transmission Baud rate. A crystal oscillator provides the frequency reference. Each port is equipped with two LED’S; a red one indicates when data is being transmitted to the remote device and a green one indicates when data is being received from the remote device. The RS-232output voltages are industry standard +3 to +15VDC, with +9VDC typical. The RS-485output voltages are industry standard +1.5 to +5VDC, with +2.5VDC typical. A loopback diagnostic test can be performed on each serial port. This test permits verification of the data transmitted from the serial port. Refer to the “Serial Inputs / Outputs Tests” description in this book for details of these tests. The graphic screens that are displayed on the Liquid Crystal Display are created from preformed graphics and messages that are stored in the Program FLASH Memory Card, and real-timesystem operating parameters, such as temperatures. The graphics, message and number data are in the form of digital words. The Display Controller converts this data into display drive signals and sends them to the Display from Microboard J5. The Display has 307,200 pixels arranged in a 640 columns x 480 rows matrix configuration. Each pixel consists of 3 windows; red, green and blue, through which a variable amount of light from the Display backlight is permitted to pass through the front of the display. Imbedded in each window of the pixel is a transistor, the conduction of which determines the amount of light that will pass. The drive signal determines the amount of conduction of the transistor and therefore the amount of light passed through the window. The overall pixel color becomes a result of the gradient of red, green and blue light allowed to pass. The drive signal for each pixel is an 18 bit binary word; 6 for each of the 3 colors, red, green and blue. The greater the binary value, the greater the amount of light permitted to pass. The pixels are driven sequentially from left to right, beginning with the top row. To coordinate the drive signals and assure the pixels in each row are driven sequentially from left to right and the columns are driven from top to bottom, each drive signal contains a horizontal and vertical sync signal Service •BRAM U52 •Flash Memory Card U46 •BIOS EPROM U45BIOS EPROM FLASH MEMORY CARDBRAM FIG. 31 – MICROBOARDService MEMORY CARD SOCKETMEMORY CARD TOP SURFACEPOWER FROMFIG. 33 – SUPPLYPins 1-2 RS-232 Pins 2-3 RS-485 TABLE 2 – MICROBOARD PROGRAM JUMPERSWatchdog protection as follows JP10 - JP26 - Not usedJP34, JP35, JP36, JP37 - Not Used JP39, JP40, JP41, JP42 - Not usedTABLE 3 – MICROBOARD PROGRAM SWITCHES for YORK factory testing onlyNEVER disable the watchdog protec tion!
