RESET command
This command causes the Servo Tyer controller to display the reason for the most recent
controller reset. It does not cause the Servo Tyer controller to reset itself. The possible
reasons for a reset are as follows.
1. Power turned off. This is the most common cause of a reset and it is quite normal
for this to occur. It occurs when the power is turned off for more than a couple of
seconds.
2. External reset. This can be caused by a momentary loss of power such as might
occur from a loose power connector. It also occurs if someone presses the reset
button on the CPU board or if someone turns the power switch on within a second
after the power has been turned off. All occurrences of external resets are also
recorded in the Trouble buffer.
3. Watchdog reset. This indicates a software error. These are indicated in the trouble
buffer.
4. Halt monitor reset. This indicates an internal processor fault. These are indicated
in the trouble buffer.
To invoke the RESET command, simply type: RESET
DEBUG command
When Debug is turned on, the Servo Tyer controller will write a statement to the screen
to indicate every time that the bag switch closes when the Servo Tyer is ready to tie. It
also writes another statement every time that the bag switch opens during normal
operation. This is sometimes helpful, if you are experiencing erratic triggering of the Servo
Tyer. Normally, Debug is turned off.
To turn on Debug, type: DEBUG=1
To turn off Debug, type: DEBUG=0
