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 shut-

down 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

Settings.

In this example, B side

pressure is higher, so

use the B side valve to

balance pressures.
