Status Code 2: Pressure Deviation from
Setpoint
The unit does not check for pressure deviation at
setpoint less than 400 psi (2.8 MPa, 28 bar).
Unit senses pressure deviation from setpoint, and warns
or shuts down, depending on settings of DIP switches 3
and 4. If equipment cannot maintain enough pressure
for a good mix with an impingement mix gun, try using a
smaller spray tip.
DIP Switch and Function
DIP Switch 1
If selected, causes shutdown or displays a warning if
there is a pressure imbalance exceeds selection made in
DIP Switch 2
DIP Switch 2
If selected, causes shutdown if A and B pressure imbal-
ance is greater than
If selected, causes warning if A and B pressure imbal-
ance is greater than
DIP Switch 3
If selected, causes shutdown or displays a warning due to
deviation of pressure from setpoint exceeds selection
made in DIP Switch 4
DIP Switch 4
Causes warning if deviation of pressure from setpoint is
greater than

To turn off automatic shutdown and/or tighten pressure
tolerances for status code 2, see Status Code 1 and 2
Settings on page 26.
Status Code 1 and 2 Settings
1. Locate switch SW2 on the control board, page 40.
