Ambient temperature is too cold.
Relocate hoses to a warmer area or
recirculate heated fluid through the
hose.
FTS failed or not installed correctly.
Check FTS, see
Check RTD Cables and FTS, page 65
.
Low supply voltage.
Verify line voltage. Low line
voltage significantly reduces power
available to the hose heat system,
affecting longer hose lengths.
Hose heats but heats
slower than usual
or it does not reach
temperature.
If Hose Resistance Mode is enabled,
the calibration factor may be
inaccurate.
Re-calibrate the hose. Follow the
Calibration Procedure, page 68
.
A and B setpoints too low.
Increase A and B setpoints. Hose is
designed to maintain temperature,
not to increase it.
Ambient temperature is too cold.
Increase A and B setpoints to
increase fluid temperature and keep
it steady.
Flow too high.
Use smaller mix chamber. Decrease
pressure.
Hose was not fully preheated.
Wait for hose to heat to correct
temperature before spraying.
Low supply voltage.
Verify line voltage. Low line
voltage significantly reduces power
available to the hose heat system,
affecting longer hose lengths.
Hose does not
maintain temperature
while spraying.
If Hose Resistance Mode is enabled,
the calibration factor may be
inaccurate.
Re-calibrate the hose. Follow the
Calibration Procedure, page 68
