4.11.3 Communication Errors
Communication Errors result from problems that the controller encounters in attempting to commu-
nicate with the other components. They do not indicate whether the problem is with the controller or
the component, although the presence of multiple Comm Errors suggests a problem with the
controller.
• Fluorometer Comm Error
• Multiprobe Comm Error
• Pellet Feeder Comm Error
4.11.4 Performance Alarms
Performance Alarms are related to the parameters that comprise the Cooling Water Triangle (scal-
ing, corrosion, microbio). The 3D TRASAR bio-control "Failsafe" alarms are so named to indicate
that the oxidizing biocide is fed in failsafe mode when those alarms are activated, and the relay must
be reset at the controller display by clearing the popup window. The bio-reporter is
never
fed in
failsafe mode.
• System Stress High
• Corrosion #1 High
• Corrosion #2 High
• Nalco Bio-Index High
• Biocide Pump Rate High
• Biocide Pump Rate Low
• Bio-reporter High
• Bio-reporter High Failsafe
• Bio-reporter Low
• Bio-reporter Low Failsafe
• Bio-product High
• Bio-product High Failsafe
• Bio-product Low
• Bio-product Low Failsafe
• Bio Data Noise High
• Bio Data Noise High Failsafe
• Pellet Rotor Current High
• Pellet Supply Low
4.11.5 Control Alarms
Control Alarms are related to the parameters that may be controlled by the 3D TRASAR controller
,
even when the parameters are only being monitored.
• TRASAR High
• TRASAR Low
• Tagged Polymer High
• Tagged Polymer Low
• Conductivity High
• Conductivity Low
• pH High
• pH Low
• ORP High
• ORP Low
Control Alarms in this category are related to Failsafe Duty and can be set to different values for High
and Low alarms via the configurator. In monitoring mode, the parameter monitored may be sepa-
rated from the relay that is on timer control for a different product.
