SYSTEM STATUS
This screen allows a choice between looking at
System faults or monitoring the status of the inputs
and outputs of the PLC.
7.11.10 SYSTEM FAULTS
In the event that the SYSTEM FAULT light is
illuminated on the control panel, this screen will
give an indication to what was the cause of the fault
and what area needs to be checked.
The E-Stops are monitored for individual input and
in the event that one is depressed, the ESR will drop
out causing the machine to stop, and it will be shown
on this display as to which one was activated.
The operational speeds of the Part Rotation, and
Blast Oscillator are monitored during the cycle. In
the event that they fall outside of their tolerance range for more than 5 seconds, a fault will be
generated and the cycle will be put on hold.
This allows maintenance to check the system and resume operation when a fix is made.
In the event that the Dust Collection System falls out of its desired operating range, a
Photohelic guage will signal the PLC of the alarm and will stop the process cycle. This is
indicated as a RECOVERY FAULT. Once normal operation of the dust collector is resumed,
the process can be continued.
7.11.11 SYSTEM INPUTS
This screen shows the current condition of all the
inputs to the PLC. Green indicates a positive or made
input, red indicates the lack or presence of a input.
