Warnings
The pattern controller monitors warning conditions like:
Trigger 1 - 4 too short (clipping), T1- 4 max distance exceeded (jamming),
Ch1 - 4 short circuit, etc.
NOTE: Warnings appear in the display. They remain visible until they are
acknowledged by pressing any button.
The pins A, B and C at the remote output (refer to Page 22) are wired as an
alarm output. The alarm output can be used for a machine stop signal or to
trigger a remote device.
When a fault occurs, there are two cases in which the alarm output is
activated. In all other cases, only a warning appears in the display.
1. Short circuit of the gun output
2. The jam detector signals a fault

Fault Condition
A fault condition occurs typically when there is a hardware or software
defect. When a fault condition occurs, the user will need to take immediate
action.
Warning Condition
A warning condition alerts the user that there may be an error with the
setup of the pattern controller. When a warning condition occurs, immediate
action may not be required.
