Status Codes

Determine the status code by counting the number of
times the status indicator (ST) blinks.

F . 9 The Status Indicator
IG
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).
NOTE: The unit does not check for pressure imbalance
for 10 seconds after entering pressure mode.
The unit senses pressure imbalance between
components 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 Status Code 1 and 2
Settings, page 30.
1. Check the fluid supply of the lower pressure
component and refill if necessary.
2. Reduce the pressure of the higher component by
slightly turning the Spray valve for that component
toward Recirc until the gauges show balanced
pressures.
NOTE: Turn the Spray valve only enough to balance the
pressure. If turned completely, all pressure will bleed off.
30
In this example, B side
pressure is higher, so use
the B side valve to balance
pressures.
3. Check the fluid inlet strainers (51a, page 27) and
the fluid filters at gun.
4. Clean or change the restrictor at the mixer manifold
if using disposable mixer gun kit.
Status Code 2: Pressure Deviation from
Setpoint
NOTE: The unit does not check for pressure deviation at
setpoints less than 400 psi (2.8 MPa, 28 bar).
The unit senses pressure deviation from setpoint, and
warns or shuts down, depending on settings of DIP
switches 3 and 4. If the 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 Status Code 1 and 2
Settings, page 30.
Status Code 1 and 2 Settings
1. Locate switch SW2 on the control board. See F
14, page 42.
2. Set the four DIP switches to the desired positions.
