Controller Fault Condition Displays
Below are examples and explanations of the displays which accompany the fault conditions
possible in the ROC-4. Fault conditions always indicated a problem of some sort which requires
corrective action. The displays provide sufficient information to recognize the source of the fault
and the required corrective action.
High Pressure Fault: (Occurs when High Pressure Switch
Closes) Line 1 “Service Fault”
Line 2 “High System Pressure” Line 3
Line 4 “To Reset Push OFF/ON”
Low Pressure Fault: (System is responding to low pressure condition per system settings) Line 1
“Service Fault”
Line 2 “Low Feed Pressure” Line 3
Line 4 “Restart in MM:SS”
Pre Treat Fault: (Pretreat Switch is closed indicating problem with pretreat system). Line 1
“Service Fault”
Line 2 “Pretreat”
Line 3
Line 4 “Check Pretreat Sys.”
Permeate Conductivity Fault: (Permeate conductivity is higher than the alarm set point.) Line 1
“Service Fault”
Line 2
“Permeate TDS xxx ppm” or “Permeate Cond xxx uS” Line 3 “Alarm SP xxx ppm” or
“Alarm SP xxx uS”
Line 4 “To Reset Push OFF/ON”
Feed Conductivity Fault: (Feed conductivity is higher than the alarm set point.)
Line 1 “Service
Fault”
Line 2 “Feed TDS xxx ppm” or “Feed Cond xxx uS” Line 3 “Alarm SP xxx ppm” or “Alarm SP
xxx uS” Line 4 “To Reset Push OFF/ON”
Conductivity Probe Error messages:
Line 2
“Over-range” - Measurement is out of range for the circuit, probe may also be shorted
Line 2
“Probe shorted”
- Short circuit detected on temperature sensor in probe
Line 2
“Probe not detected” - Open circuit detected on temperature sensor in probe
Line 2 “Probe Startup 1”
- Internal reference voltage too high to make valid measurement
Line 2 “Probe Startup 2”
- Internal reference voltage too low to make valid measurement
Line 2 “Probe Startup 3”
- Internal excitation voltage too high to make valid measurement
Line 2 “Probe Startup 4”,
- Internal excitation voltage too low to make valid measurement
