7.2 TROUBLESHOOTING
7.2.1 ERROR CODES
There are two types of error conditions in the system: emergency shutdown (ESD) conditions and warnings. An
ESD will show red in RHS Control and shut the machine down. A warning will show up as yellow in RHS Control and
will not influence the machine's running. If warning or err
ors persist after you’ve performed the resolution,
perform full power cycle before contacting the Support team at RH Systems ( support@rhs.com ).
EMERGENCY SHUTDOWN CODES DESCRIPTION RESOLUTION
6 [Pl/Ph] Bad pressure Sensor

sensors is too high. Pressure sensors need
recalibration.
Faulty Saturator/Chamber
select solenoids (SOL4 &
SOL5) (see section 6.2.7).
17 [Tp] Presat Temperature
Missing Presat temperature sensor is not
reading and is possibly
disconnected. Check pre saturator
temperature sensor (Ch1)
connection or check
temperature measurement
board (see section 6.7 or
6.1.3).
18 [TS] Sat Temperature Missing Sat temperature sensor is not
reading and is possibly
disconnected. Check saturator
temperature sensor (Ch2)
connection or check
temperature measurement
board (see section 6.7 or
6.1.3).
19 [Tev] Expansion Valve
Temperature Missing Expansion valve temperature
sensor is not reading and is possibly
