Status Codes
Determine the status code by counting the number of
times the status indicator blinks.
Status Code 1: Pressure Imbalance
NOTE:
The unit does not check for pressure imbalance
at setpoints less than 250 psi (1.75 MPa, 17.5 bar). The
unit does not check for pressure imbalance for 10 sec-
onds after entering pressure mode.
Unit senses pressure imbalance between components
A and B, and warns or shuts down, depending on set-
tings of DIP switches 1 and 2. To turn off automatic
shutdown and/or tighten pressure tolerances for status
code 1, see
Status Code 1 and 2 Settings
.
1. Check fluid supply of lower pressure component
and refill if necessary.
2. Reduce pressure of higher component by
slightly
turning Recirc/Spray valve for that component
toward Recirc, until gauges show balanced pres-
sures.
NOTE:
Turn Recirc/Spray valve only enough to balance
pressure. If turned completely, all pressure will bleed off.
3. Check fluid inlet strainers and fluid filters at gun.
Status Code 2: Pressure Deviation
from Setpoint
NOTE:
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 at the gun, try using a smaller mix cham-
ber or nozzle.
To turn off automatic shutdown and/or tighten pressure
tolerances for status code 2, see
Status Code 1 and 2

In this example, B side
pressure is higher, so
use the B side valve to
balance pressures.
