Table 14 Liebert HPC (Chiller) - Glossary Controller Liebert iCOM v4 Data Label Data Description Modbus 485 and Modbus IP Protocols - Precision Cooling Products Actual Supply Fluid Temp Set Point The actual set point value being used for the desired fluid temperature at the outlet of the unit. All Pumps Loss of Flow System is shut down due to loss of flow in all available pumps. Ambient Air Temperature Sensor Issue The ambient air temperature sensor is disconnected or the signal is out of range. Ambient Air Temperature Ambient air temperature. Compressor Capacity Control State Compressor capacity control state. When 'ON', the cooling capacity of the compressor has been reduced. Compressor Capacity Normal Compressor has returned to normal load capacity. Compressor Capacity Reduced Compressor capacity has been reduced. Compressor Contactor Issue Compressor contactor is not closing during compressor startup or is not opening during compressor shutdown. Compressor Economizer Utilization Present compressor economizer utilization expressed as a percentage of the maximum. Compressor Head Pressure Compressor head pressure. Compressor High Head Pressure Compressor is shut down due to high head pressure. Compressor Hours Exceeded [Compressor Hours] has exceeded [Compressor Hours Threshold]. Compressor Hours Threshold Threshold value used in the [Compressor Hours Exceeded] event. Compressor Hours Operating hours for compressor since last reset of this value. Compressor Loss of Differential Pressure Compressor is shut down due to low differential pressure. Compressor Low Oil Pressure Compressor low oil pressure. Compressor Low Suction Pressure Compressor is shut down due to low suction pressure. Compressor Not Stopping Compressor commanded to stop, but continues to run. Compressor Shut Down - Ambient Air Low Temp Limit Compressor State Compressor operational state. Compressor Superheat Over Threshold When the temperature of ambient air falls below this lower threshold, the compressor will be shut off. Correct condensing pressure cannot be achieved when temperature is too low. Compressor discharge refrigerant superheat temperature has exceeded an upper threshold. Compressor Thermal Overload Compressor is shut down due to thermal overload. Compressor Utilization Present compressor utilization expressed as a percentage of the maximum rated capacity. Condenser Adiabatic Cooling Utilization Present adiabatic cooling utilization expressed as a percentage of the maximum. Condenser Fan Issue Condenser fan is not operating within its operational parameters. Condenser Fan Speed Condenser fan speed expressed as a percentage of the maximum rated speed. Condenser Inlet Water Temperature Condenser Max Fan Speed Override Condenser Outlet Water Temperature Customer Input 1 Customer input 1. Customer Input 2 Customer input 2. Customer Input 3 Customer input 3. Customer Input 4 Customer input 4. For water cooled condensers, the temperature of the water entering the heat exchanger, before cooling the refrigerant. Fan speed exceeding the maximum set point in order to alleviate a high temperature or pressure condition. For water cooled condensers, the temperature of the water exiting the heat exchanger, after cooling the refrigerant. 50
Table 14 Liebert HPC (Chiller) - Glossary (continued) Controller Liebert iCOM v4 Data Label Data Description Evaporator Fluid Freeze - Auto Reset Evaporator Fluid Freeze - Manual Reset Required Evaporator Inlet Temp Sensor Issue Evaporator Return Fluid Over Temp Alarm Threshold Evaporator Return Fluid Over Temp Warning Threshold Evaporator Return Fluid Over Temp Evaporator Return Fluid Temperature Evaporator Return Fluid Under Temp Alarm Threshold Evaporator Return Fluid Under Temp Warning Threshold Evaporator Return Fluid Under Temp Modbus 485 and Modbus IP Protocols - Precision Cooling Products Evaporator outlet fluid temperature has dropped below the freeze threshold. Evaporator has been shut down, but will restart when the temperature rises above the threshold. Evaporator outlet fluid temperature has dropped below the freeze threshold. Evaporator has been shut down and requires a manual reset. The evaporator inlet temperature sensor is disconnected or the signal is out of range. Alarm threshold value used in the [Evaporator Return Fluid Over Temp] event. Warning threshold value used in the [Evaporator Return Fluid Over Temp] event. [Evaporator Return Fluid Temperature] has exceeded a threshold. The event is deactivated when the temperature drops below the threshold. Fluid temperature measured at the inlet of the evaporator. Alarm threshold value used in the [Evaporator Return Fluid Under Temp] event. Warning threshold value used in the [Evaporator Return Fluid Under Temp] event. [Evaporator Return Fluid Temperature] has dropped below a threshold. The event is deactivated when the temperature rises above the threshold. Fluid Cooling Proportional Band Temperature control band above [Actual Supply Fluid Temp Set Point]. If [Return Fluid Temperature] is within this band, fluid cooling operations are proportionally controlled. Fluid Pressure Fluid pressure. This is the pressure within a closed water/glycol circuit. Free Cooling External Temperature Delta Minimum temperature delta required between return fluid and external ambient air temperatures in order to enable free cooling. Free Cooling Status Free cooling status. Free Cooling Utilization Present free cooling utilization expressed as a percentage of the maximum. Free Cooling Valve Hours Exceeded [Free Cooling Valve Hours] has exceeded [Free Cooling Valve Hours Threshold]. Free Cooling Valve Hours Threshold Threshold value used in the [Free Cooling Valve Hours Exceeded] event. Free Cooling Valve Hours Operating hours for free cooling valve since last reset of this value. Free Cooling Valve Open Position Free cooling valve open position. Humidifier Control Board Not Detected Humidifier control board is required to be connected, but no signal is detected. Low Condenser Refrigerant Pressure Refrigerant pressure in condenser coil is too low. Low Fluid Pressure [Fluid Pressure] has dropped below a specified threshold. Master Unit Communication Lost Communication with master unit has been lost. Pump 1 Loss of Flow Loss of flow is detected in pump 1. This condition occurs when no flow is detected through the flow switch. Pump 1 State Pump 1 operational state. Pump 2 Loss of Flow Loss of flow is detected in pump 2. This condition occurs when no flow is detected through the flow switch. Pump 2 State Pump 2 operational state. Pump Hours Exceeded [Pump Hours] has exceeded [Pump Hours Threshold]. Pump Hours Threshold Threshold value used in the [Pump Hours Exceeded] event. Pump Hours Operating hours for pump since last reset of this value. RAM Battery Issue RAM or RAM backup battery is not operating correctly. 51
