2.2 Output Relays
This test checks that the output relays are functioning correctly. The output relays should be energised in turn and
the contacts should be checked for correct operation using a continuity tester. The output relays can be energised
in a number of ways. The following is the recommended method:
Assign each output relay in turn to ‘Relay Healthy’ in the output relay menu. On pressing the ENTER key the
output relay selected will be energised. Check with a continuity tester that the actual contacts have operated. De-
select the output relay and check that the contact returns. Consult the schematic diagram or Relay Connections
Diagram in the Technical Manual for terminal numbers.
