Notes and special instructions. 1. Counting and zeroing signals can only be inputted as non-voltage contact signals, no other electrical signals can be inputted. 2. The contact input should be reliable, so as to avoid false counting caused by contact jumping back, jittering, poor contact, and so on. 3. Avoid the same pipe or stranded wires with strong electric wires or power wires to avoid unnecessary interference. 4.
