CHANGING THE OUTPUT CONTACT (N.O. <> N.C.)
If necessary it is possible to change the N.O. (normally open contact)
present on the output channels 1 and 2 to a N.C. contact (normally
closed). On the board there are some weld-on contacts near the
relays (see figure alongside): the J2 contacts refer to channel 1, the J3
contacts refer to channel 2:
Using a welding machine for electronic items, remove the weld that
connects the contacts B-C and make a jumper between the contacts
A-B.
