setting on blank material, turn the “Trim Pot” counterclockwise until the “Amber
Light” below the “Trim Pot” goes out. Slowly turn the “Trim Pot” clockwise
until the “Amber Light” comes back on. Move the web until the green light
beam sets directly over the registration mark and the “Amber Light” should go
out. If the “Amber Light” stays on - rotate the “Trim Pot” counterclockwise
until it goes out. Move the web slightly left to right by hand so the green light
moves from the registration mark to blank material and watch the “Amber
Light”. The light should quickly flash on and off. If the “Amber Light” is slow
to react turn the “Trim Pot” 1/8 turn clockwise and retest until the light toggles
quickly.
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, , 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.
