Output Test (Relay)
The first step in testing the operation of the function
outputs is to confirm the positions of the outputs in
the unoperated or
OFF
position. This can be
accomplished by connecting a DMM across the
appropriate contacts and confirming open or closed
contacts. The de-energized or
OFF
positions for
each output is listed in Table 6-2, Output Contacts
