18. Run the metering pumps until the material has
reached the desired temperature.
NOTE: If you circulate the A side metering pump at
pressures greater than 3000 psi (21 MPa, 210 bar), an
advisory is issued and the yellow LED on the display
illuminates. This is a reminder to select Spray mode
prior to spraying and to circulate at a lower pressure to
avoid excessive pump wear.
NOTE: If you circulate the A side metering pump above
5200 psi (35.4 MPa, 354 bar), an alarm shuts down the
pump to prevent accidentally spraying material while still
in circulation mode.
NOTE: If the circulation valves are closed while
circulating, but the control is left in Circulation Mode, the
machine will alarm after 5 seconds and exit Circulation
Mode. This is done to prevent spraying in Circulation
Mode.
