Before configuring the PEARL, it is easy to test if the economizer
actuator is correctly wired to the PEARL (A1) output terminal and to
verify damper movement. When powered ON (A1) will output 2.0
VDC. This is the default and typically used as the closed damper
position.
Pressing the MOVE button
will output the opposite voltage or
10.0 VDC. Status light 1 (green light) will begin flashing indicating
the PEARL is moving the damper to the open position.
Opening economizer damper
Pressing the MOVE button again will switch the output back to 2.0
VDC. Status light 2 (blue light) will begin flashing indicating the
PEARL is moving the damper to the closed position.
Closing economizer damper
The MOVE button
can be pressed as many times as required to
test the actuator and damper movement. Flashing green always
indicates the PEARL is outputting a high DC voltage or is opening
the damper, flashing blue always indicates the PEARL is outputting
a low DC voltage or is closing the damper.
