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 com-
ponents A and B, and warns or shuts down,
depending on settings of DIP switches 1 and 2.
To turn off automatic shutdown and/or tighten
pressure tolerances for status code 1, see Sta-
tus Code 1 and 2 Settings on page 27.
1. Check fluid supply of lower pressure com-
ponent 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 pressures.
3. Check fluid inlet strainers (51a, page 23)
and fluid filters at gun.
4. Clean or change restrictor at mixer mani-
fold if using disposable mixer gun kit.
Status Code 2: Pressure Deviation
from Setpoint
Unit senses pressure deviation from setpoint,
and warns or shuts down, depending on set-
tings 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 mix chamber or nozzle.
To turn off automatic shutdown and/or tighten
pressure tolerances for status code 2, see Sta-
tus Code 1 and 2 Settings on page 27.
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 pres-
sure mode.
ST
TI7016a
Turn Recirc/Spray valve only enough to
balance pressure. If turned completely, all
pressure will bleed off.
The unit does not check for pressure
deviation at setpoint less than 400 psi
(2.8 MPa, 28 bar).
In this example, B side
pressure is higher, so
use the B side valve to
balance pressures.
