PRESSURE ADJUSTMENT
The intervals at which the compressor loads and unloads, are controlled by adjustable settings within the T1
microprocessor.
The unload setting is typically 10 psi over the customer’s required system pressure
.
The
load pressure setting controls the set pressure. The Variable Frequency Drive (VFD) will speed up the motor
or slow it down to maintain the set pressure.
6.12.1
CHANGING LOAD AND UNLOAD PRESSURES
To change the load and unload pressures, access the P01 menu in the T1 microprocessor, then select the
PL or PU parameters. Raise or lower the settings by using the
+
or
-
buttons. Select
ENTER
to save the new
setting. The T1 microprocessor will keep a minimum of 3 psi between the load and unload pressures.
