Installation notes
- Each terminal block holds a single CHARM and provides the keying and field wiring for the CHARM.
- The CHARM Terminal Block's keying mechanism sets itself to match the inserted CHARM.
- To reset the keying mechanism, remove the CHARM Terminal Block from the CHARM Baseplate, flip the terminal block 180°, and use your fingers to push the two keying posts completely in so they are sub flush to the bottom face of the terminal block. Sub flush is the neutral position. You will hear a click when the posts are in the neutral position. When the posts are in the neutral position, the terminal block can receive a different CHARM type.
- All CHARM types except the Thermocouple / mV input CHARM can use the CHARM Terminal Block.
