Note:
1. The permissive signal 'ARC1-VCHK' is required for ARC SHOT1 operation, but has
been omitted for clarity in this figure.
2. 'ARC1-VCHK' permissive signal is introduced automatically in the TPAR mode. For
ARC-SHOT2 and onwards, the user must introduce the permissive signal from the
VCHK function by using PLC programming.
