3.3.3.7 RANGE 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.
