Troubleshooting
Hose Heat System
Before performing anytroubleshooting procedures:
1. Relieve Pressure. See
Pressure Relief Procedure, page 46
.
2. Turn main power switch OFF.
3. Allow equipment to cool.
Problem
Cause
Solution
Ambient temperature is too cold.
Use auxiliaryhose heat system.
Hose heats but heats slower
than usual or it does not reach
temperature.
FTS failed or not installed correctly. Check FTS, see
Repair Fluid
Temperature Sensor (FTS), page
72
.
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 does not maintain
temperature while spraying.
Hose was not fullypreheated.
Wait for hose to heat to correct
temperature before spraying.
A and/or B heaters are overheating
material.
Check primaryheaters for either
a RTD problem or a failed
element attached to RTD, see
Electrical Schematics, page 134
.
FaultyFTS connections.
Verifythat all FTS connections are
snug and that pins of connectors
are clean. Unplug and re-plug
RTD wires, cleaning off anydebris.
Hose temperature exceeds
setpoint.
Ambient temperature is too high.
Cover hoses or move to a location
with a lower ambient temperature.
