When SS (K) times out, SS (U starts and should another sample check reed pulse find the check reed relay point closed again (5 ms later) the Coil Protect latch is set

Current flow could be due to turning a HD on due to print compare.

If this is the case, the block check latch is set preventing the check.

The block check latch is reset after every sample.

Coil protect is also set when an individual HD cannot be reset during limit switch to block a coil protect check when the switch is open and the current is limited. (From PC)-PLB Parity Wrong Write C t r l 1 J - 42039D Clock 34

With current limited coil protect checks can occur while in a print operation, but hammers do not fire and print ready is not dropped. The +60 volt line is limited by a 100 ohm resistor. This allows checking for the failing position while printing.
