3.3.3.6RANGE ID RELAYS

There are three dedicated Range ID relay contacts. They are assigned to relays in ascending order—Low range is assigned to Range 1 ID, Medium range is assigned to Range 2 ID, and High range is assigned to Range 3 ID. Table 3-6 lists the pin connections. Contacts are normally open, and they close when 4040 switches to that particular range.
