Testing equipment connected to relays
The Supra has two displays for testing equipment connected to relays: one for viewing the states
(ON or OFF) and one for manually testing the equipment connected to each relay. The relay tests
are useful for detecting faulty connections or configuration errors.
Before testing equipment connected to relays, make sure you know what is
connected to each relay. Testing relays without knowing which equipment is
connected to them can damage your equipment. For example, switching on an
actuator’s open and close relays at the same time can damage the
actuator
power supply and the Supra’s relays
.
For more information about what is connected to the Supra, see your installation
worksheets.

The display should look like the following example.
If a relay is closed, the display shows

next to the relay. If a relay is open, the display shows

Confirm the equipment is producing the proper output for the current relay state. Go to the
equipment connected to each stage and check that it is on if the state displays
On
, or off if the

If the displayed states are correct, go to step 9. If any are incorrect, go to the next step.
