LCD Display
The LCD display is a 2 line, 24 character, with back lighting feature for
easy readability. The first line of the display in most cases will be a
prompt or question. The second line is the response to the prompt or
question.
Diagnostic Tests
During power up the following tests and screens will be displayed.
DIAGNOSTIC TEST 1
This screen is displayed during the Control Panel test.
This screen will be displayed while the Front Panel is initializing and
waiting for the MIB response.
The code will check the functionality of the LED's and the display. Each
state of the LED's will be checked - (red, green, amber and off). The
code will check the LCD display by writing a character to the display,
checking for communications and then reading the character back and
comparing with the code. If an error occurs, the code will halt the
diagnostic test and blink the ERROR LED.
The keypad is also checked during DIAGNOSTIC TEST 1. Each key is
tested to see if it is stuck on. If a fault condition is detected, the test is
halted and the screen will display the first error key found with the
following display:
(BUTTON NAME) KEY STUCK
DIAGNOSTIC TEST 1
The (BUTTON NAME) will be one of the push button names on the front
panel - START, FEED, TEST, STOP, EXIT, MODE, <YES, NO>, OR
ENTER.
When the code has finished the above tests, the code will attempt to
communicate with the 196 Machine Control Board (MIB). If all tests are
complete and no errors detected, then the system will go to the HOME
screen.
