The <Current Check> input signal must be set.
Now, the timer is in <Current Check> mode. No starts or program selections entered in
the I/O field will be accepted.

currents are measured. Subsequently, the primary current is checked for any deviation
beyond a specified limit (stated in %) from the secondary current (which is the reference
current in this case). If the primary current exceeds the tolerance limit, an error message
is transmitted.
-
Upon correct completion of the <Current Check>, the <Current scaling/
check finished> signal becomes high and is held until the <Current
Check> input signal is reset.
