C.4 E-STOP PROBLEMS AND ANALYSIS
C.4a Troubleshooting the E-stop / Interlock System
Problem:
The condition described is a cover when first open, then closed, and it takes
the E-stop button to be pressed and released then the Restart button
pressed in order to run the machine again instead of just closing the cover
and pressing the restart button.
Some questions:
Does this happen with all the covers or just one specific cover?
Accumulator? feeder? 2 Folder Plate covers? Transfer Conveyor Covers?
Etc...?
Analysis:
The E-stop system actually consists of 2 separate sets of 2 loops. The
covers are connected through 2 series strings and the E-stop Button is
another set of 2 series strings. When a cover opens, both series strings
must open in order to make the E-stop controller happy.
If it happens with just one cover, then one of the 2 magnetic reed relay
switches is always closed (or shorted). This can also occur if one of the blue
bypass jumpers on the Input Output Interconnect Board has not been
removed from the offending module. These should be measured and
checked.
By cycling the E-stop button, you effectively remove power to the e-stop
controller and reset it.
