If a test is carried out while there is a coin going through the Validator, it
may return an erroneous error message. It is necessary to do the test
various times before putting the Validator out of order.
If the Validator is put out of order deliberately, it may be necessary to
establish a reset mechanism when the Validator does respond to a later test
command correctly and without errors
.
It is also advised to carry out another test before communicating a fault in
the Validator to Central.
