1. If at least one gun works, problem is not with control unit PC board. If control unit PC board is bad,
no gun will work.
2. If more than one gun does not work, while others do, there is a high probability that the problem
is the MGS PC board. (chances are low that multiple guns, connections or flow switches would fail at
the same time).

the MGS unit. Was proper reading
obtained?
Turn IGC board toggle switch off. Does
gun work?
