Wire Thermal Overloads
Additional thermal overload protection for your blower can be obtained by wiring from the Normally Closed thermal
overload contacts of your blower external motor starter to the ORS SITEPRO™ panel. Wire to input terminals 5 and 7 on
TB3 after removing the existing jumper.
Set Blower Time Delay
As delivered from the factory, the panel is wired to shut down the blower 3 minutes after a High or Low Pressure condition
is detected. The time delay can be reduced to 7 seconds by installing a jumper between terminals TB4-5 and TB4-7.
When a blower thermal overload is sensed (blower thermal overload contacts
open), the blower will shut down and the THERMAL OVERLOAD indicator on
the panel will be illuminated.
