Status Codes
Determine the status code by counting the number of
times the status indicator (ST) blinks.
Status Code 1: Pressure Imbalance
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 shut-
down and/or tighten pressure tolerances for status code
1, see Status Code 1 and 2 Settings on page 26.
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.
3.
Check fluid inlet strainers (51a, page 22) and fluid
filters at gun.
4.
Clean or change restrictor at mixer manifold if using
disposable mixer gun kit.
ST
r_256765_313221_b_37
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 after entering pressure mode.
Turn Recirc/Spray valve only enough to balance
pressure. If turned completely, all pressure will
bleed off.
In this example, B side pres-
sure is higher, so use the B
side valve to balance pres-
sures.
