On single actuated economizer assemblies you will normally have mechanically linked return, outside and sometimes exhaust dampers. The return damper should be opposite of the outside and exhaust dampers. For example, if the PEARL outputs 10VDC the outside and exhaust dampers will be at 100% open and the return damper should be at 100% closed.
If you installed the feedback signal to the PEARL (step 4 above), you can use the auto-test sequence to verify your dampers are moving correctly. This is explained in the PEARL’s installation guide.
If you do not have the feedback signal, you will want to finish configuring the PEARL through the Pelican App. Then you can turn the Fan to On and the PEARL will open the outside damper to the Minimum Damper Configuration. If you temporarily set the Minimum Damper Configuration to 100%, then the outside damper should go to 100% open and the return damper should go to 100% closed.
During testing if the actuator is not moving in the correct direction, the actuator will normally have a toggle on it that allows you to change the direction it is moving.
