CAUSE
FTS failed or is not contacting
correctly.
FTS not installed correctly.
Temperature control alarm.
Shorted connection or failed hose heating
element.
SOLUTION
Check FTS. See E04: Fluid
Temperature Sensor (FTS) or
thermocouple disconnected, page 13.
FTS should be installed close to end of
hose in same environment as gun. Verify
FTS installation, page 35.
Check temperature display or diagnostic
code. See Fluid Temperature Sensor
(FTS), page 35.
With hose heat on and temperature
setpoint above displayed hose zone
temperature, verify voltage between
connectors at each section of hose.
Voltage should drop incrementally for
each section of hose further from
Reactor. Use safety precautions when
hose heat is turned on.
