6.5 PRESSURE ADJUSTMENT
To change the load and unload pressures, or to see the fault history press the + and - keys
simultaneously. Use the + or - keys to set the code to 0009. Use the ENTER key to move forward a digit
and to enter when complete. This will allow access to P-01 and P-02, operation and fault history menus.
Use + or - to scroll through the menu pages, ENTER to select a page, + or - to scroll through the
parameters, ENTER to select the one to change. Use + or - to change the value, ENTER to store, and C
to move back out.
The load pressure setting on the T1 microprocessor controls the set pressure. It will speed the motor or
slow it down to maintain this pressure. Once the motor is running at the minimum pressure, pressure will
creep up to the unload pressure where the compressor will unload. To change the control pressure
setting, load setting, access P-01 above, and scroll to Pl parameter. Press ENTER. Raise or lower the
setting using the up or down arrow keys. It will increase or decrease the pressure as you move the
setting, but will not store the value until you press ENTER. It will still vary between the load and unload
pressures unless you also change the unload pressure. The T1 will keep a minimum of 3 PSI between
the load and unload pressures. Do not bring the control set point up as this may increase the current to
levels the drive will fault on. Consult the factory if there are any questions.
If the pressure reading is cycling up and down between load and unload rapidly, you can decrease the
load pressure to help it gain control. Don’t go above the factory setting. There are also some additional
control parameters in the microprocessor which can further smooth the operation. These P and I control
functions are in the P-08 menu. It is best to have a surge tank after the compressor.
6.6 SERVICE/MAINTENANCE PROCEDURES
After changing the air filter element, oil, separator, or oil filter, the service timer on the microprocessor
must be reset.
Use the + key to scroll to P04. Press ENTER. H3 will be in the parameter field. Press ENTER to change.
Use the + key to set the time until the next service of the oil filter. Press ENTER to save. Press the + or –
to scroll to the next timer you want to reset. Press ENTER to select, and ENTER again to change. After
changing with the + or – keys, press ENTER to save. When finished, press the C button to exit to the P04
menu and C again to exit to the main screen. If there were any alarms for the service timers, they may
now be reset with the RESET key. When finished, press the C button to exit to the P04 menu. Press C
again to exit back to the operations screen. Please note these are countdown hours until the next service
is needed.
