Using LEDs As Diagnostic Tools
The following sections describe the functions of LEDs on the AutoSet processor board (see
Figure 2-4 or Figure 2-5) and show you how to use them to diagnose problems.
Remote Reset, Zero Cam, and Setup LEDs
These three LEDs are located at the lower left of the AutoSet processor board just below the
TB101B (1500 units) or TB101A (1504 models) connector and are labelled “Rem Rst”
(DS108), “Z Cam” (DS104), and “Setup” (DS105).
The three LEDs, which are red, indicate the presence of wiring connections at the Remote
Reset (pin 1), Zero Cam (pin 2), and Setup (pin 5 on TB101A, pin 8 on TB101B) terminals on
TB101 connectors. (Pin 5 and pin 8 are not functional on standard AutoSet 1500 and 1504
units, which do not have a repeatability function and, therefore, do not support a Setup Mode.)
When the pin connection is wired properly, the corresponding LED should be lit. If one of
these LEDs does not illuminate, you should first check the wiring at the appropriate pin
number. If the wiring checks out, there may be a problem with that input. Contact Wintriss
Tech. Support for assistance.
Reset, Repeatability Select, and Reverse Select LEDs
These three red LEDS are located just beneath the “Mode” switch block (S101) on the left
side of the AutoSet processor board and are labelled “Reset” (DS101), “Rep Sel” (DS102),
and “Rev Sel” (DS103). On AutoSet Plus units, these LEDs indicate whether the DISPLAY
switch and REVERSE button on the front panel are working properly. On standard AutoSets,
the “Reset” LED indicates whether the RESET button on the front panel is working.
The Reset LED should illuminate when the DISPLAY switch on AutoSet Plus units is turned
to the RESET position or the RESET button on standard AutoSets is pushed. The
Repeatability Select LED should light up when the DISPLAY switch on AutoSet Plus units is
turned to the REPEATABILITY position. The Reverse Select LED should turn on when the
REVERSE button on AutoSet Plus units is pushed. The “Rep Sel” and “Rev Sel” LEDs are
not functional on standard AutoSet units.
If one of these LEDs does not illuminate when the appropriate switch is actuated, check the
ribbon cable connections at the processor and display boards, the ribbon cable itself, and the
wiring connections to the DISPLAY switch or RESET button. If the connections are good
and the LED(s) still does not illuminate, call Wintriss Tech. Support.
