MOI-7, MOD-16, MID-16 Connections and Ratings
Local Trouble Input
When terminal 3 of TB3, the local
trouble input, is driven high, it reports a
trouble condition to the MXL. This
input is protected and has a maximum
input rating of 40V. Terminal 2 of TB3
is the common for this input.
Local Lamp Test
Terminal 1 of TB3 is used for a local
lamp test. When this input is pulled
low, the MOD-16 outputs do a lamp
test. Use a normally open momentary
switch connected between terminal 1
and 2 of TB3.
