and older style 10K pendant operation. See Section 7-11.3 for details.
DS12
Red
Monitors the watchdog timer.
Normally OFF.
The LED will illuminate momentarily when power is applied to or removed from the system. If
the LED is continuously flashing or ON, the computer is not working properly. If LED is ON
constantly (no flashing), the +5 VDC is probably too low. This could be caused by shorts on the
board or by a defective voltage regulator. If the LED flashes at a constant rate, the microcomputer
chip or EPROM may be defective.
