Operation 3.0 OPERATION The Liebert iCOM display for your Liebert cooling unit features an easy-to-use, menu-driven liquid crystal display (LCD). All unit settings and parameters can be viewed and adjusted through three menus: User, Service and Advanced. All active alarms are displayed on the LCD and annunciated. The control is shipped from the factory with default selections for all necessary settings. Adjustments can be made if the defaults do not meet your requirements.
Operation Autorestart When there is a loss of power to the cooling unit and power comes back, the unit will return to its previous operating status—on if it was on before the power off, off if it was off. When power returns, the autorestart time—time-selectable: Single Unit Auto Restart (Service Menu, Options Setup)—controls the start of the unit. The autorestart time runs in a loop, starting the next unit each time when elapsed, starting with Unit # 1.
Operation 3.1.3 General Compressor Requirements Low-Pressure Time Delay When the compressor starts, the low-pressure input is ignored for a selected period of time based on the setting of the Low Pressure Alarm Delay (Service Menu, Options Setup). This time is usually set to 3 minutes on air-cooled units, and to 0 or 1 minute on water cooled units. When this time is expired, a second timer starts to operate if the low-pressure input is active.
Operation Digital Scroll High Temperature A protective maximum operating compressor temperature limit is imposed on units with digital scroll compressor(s) with thermistor. Once the digital scroll temperature reaches the maximum temperature threshold, the compressor will be locked out for at least 30 minutes and an alarm will be annunciated. If after 30 minutes the temperature has cooled to a safe operating temperature, the compressor will resume operation.
Operation 3.2 Motorized Ball Valve in Digital Scroll Units On digital scroll units, discharge pressure is controlled by a motorized ball valve. During unloaded operation, pressure changes during each digital cycle could cause a pressure-controlled water regulating valve to open and close an excessive number of times. The motorized ball valve is designed to maintain a consistent peak discharge pressure on Water/Glycol Cooled Digital Compressor Systems.
Operation 3.3 Temperature Control—Single Source Cooling (No Extra Cooling Coil) 3.3.1 Temperature Proportional Band The control uses the temperature proportional band to determine which operation to perform (cooling/heating) and how intensely to perform it. The Temperature Proportional Band is a user-defined range that is divided into two equal parts for cooling and heating. The Temperature Setpoint is between these two equal parts.
Operation 3.3.2 Compressor Control Depending on the type of Liebert air conditioning unit you have your unit may contain one or two compressors with or without unloaders. Compressor Proportional Bands One Single-Step Compressor Without Unloaders—One-Step One single-step compressor, Cool 1, is started at 100% call for cooling from the temperature proportional band and stopped at 0% (see Figure 12).
Operation Two Compressors With Unloaders—Four-Step The first two-step compressor is started unloaded at 33% calculated output from the temperature proportional band and stopped at 17%. At 80% Compressor 1 will be loaded, at 70% unloaded. The second compressor starts unloaded at 63% and stops at 47%. At 100%, Compressor 2 will be loaded, at 90% unloaded (see Figure 14).
Operation Digital Scroll Compressors A compressor with a suction cutoff unloader can only modulate its capacity between two distinct levels: fully loaded and half loaded. A digital scroll compressor can modulate its capacity anywhere between 10-100%. This variable capacity modulation allows cooling units to control an environment more precisely. Digital scroll capacity modulation is achieved by energizing and de-energizing a solenoid valve on the compressor.
Operation 3.3.3 Chilled Water Control The chilled water control valve is adjusted proportionally as the temperature control varies the requirement for cooling from 0% to 100%. Units with the optional variable speed drive (VSD) control the fan speed in a similar manner, except that the minimum fan speed is 60% when the cooling requirement is less than 60%. Also, the fan is operated at 100% on a call for any heating and/or humidification.
Operation The Value setting is the factory default setting on free-cooling and dual cooling units. If the temperature difference between the second source cooling fluid parameter, Free-cooling Fluid Temperature (User Menu, Sensor Data) and room air is equal to or greater than the adjustable DT Between Room Air / FC Fluid (Service Menu, Setpoints) value, then the second source cooling fluid will be used to provide at least partial cooling (delta T between room and glycol = true).
Operation GLYCOOL™ Cooling—Free-Cooling When GLYCOOL cooling is available, the temperature control will calculate a total cooling requirement of 200% rather than 100%. Assuming that full GLYCOOL capacity is available, the GLYCOOL valve opens proportionally as the requirement for cooling rises from 0 to 100%. If more than 100% cooling is required, then the compressors are activated at 150% and 200% respectively (133%, 163%, 180% and 200% for a four-step system).
Operation Figure 19 Three-stage heating Temp Setpoint: 70°F Proportional Band: 8°F Deadband: 2°F Heat 3 Heat 2 On On 65 -100 % Heating 66 Heat 1 On 67 Heat 3 Off 68 Heat 2 Off ½ Proportional Band Decreasing Temperature 24 ½ Deadband 69 Heat 1 Off 70 0% Heating
Operation 3.5.2 SCR Reheat SCR reheat is a type of electric reheat that provides tighter temperature control than staged electric reheat. SCR reheat capacity modulation is achieved by pulsing the reheat On and Off. Full capacity is achieved by constantly energizing the reheat. Units equipped with SCR reheat can operate in Tight or Standard mode. By default, cooling units with SCR reheat are factory-set to operate in Tight mode.
Operation Standard Mode In Standard mode, the SCR reheat operates only when the Temperature Proportional Band calls for heating. SCR reheat output is adjusted proportionally as the Temperature Proportional Band varies the requirement for heating from 0% to -100%. Compressors operate only when there is a call for cooling as described in 3.3.2 - Compressor Control. Figure 21 illustrates how SCR reheat operates when SCR Control Type is set to Standard mode.
Operation 3.6 Humidity Control The control uses the humidity proportional band to determine which operation to perform (dehumidification/humidification) and how intensely to perform it. The Humidity Proportional Band is a user defined range that is divided into two equal parts for dehumidifying and humidifying. The Humidity Setpoint is located between these two equal parts.
Operation 3.6.1 Humidification Infrared Humidifier There are two types of infrared humidifiers: small pan (IFS) and large pan (IFL). The operating mode of each is similar, however, some of the variables or timings differ. Infrared humidifiers are started at 100% humidification request, and stopped at 0%. Infrared humidifiers cannot be driven in proportional mode.
Operation 3.6.2 Dehumidification The Dehumidification Enable parameter (Service Menu, Options Setup) allows for enabling/disabling the dehumidification function. A call for dehumidification is calculated in the same way as a cooling request. The components (valves, compressors) will follow this dehumidification request as soon as it is higher than the request for cooling. Dehumidification Low Limit Low Limit 1 and Low Limit 2 are used to avoid overcooling a room during dehumidification.
Operation Reheat During Dehumidification Hot gas reheat or hot water reheat will start as described in 3.5 - Temperature Control—Reheat, when the temperature decreases during the dehumidification process. The parameter Electric Reheat Operation defines how the heaters react in case the temperature decreases during the dehumidification process. This parameter does not impact SCR reheat operation.
Operation Intelligent – If Intelligent Control is selected, the return air temperature/humidity is controlled at or near the setpoint. The percent temperature/humidity adjustment required is calculated based on logic that is programmed into the control. These rules simulate the actions that a human operator would take if manually controlling the system. This control type is commonly selected on chilled water units.
Operation 3.7.3 Supply Limit—Optional Chilled water units may be ordered with an additional sensor for monitoring the supply air temperature. This sensor maintains the minimum air temperature under a raised floor to help prevent condensation from forming. In order to avoid supply temperatures that are too low, the Supply Limit can influence the opening of three-point or analog actuators or the output of analog values.
Operation 3.7.5 User Inputs / Customer Inputs The user can connect and specify up to four inputs depending on unit configuration. The user inputs/customer inputs are digital inputs that influence the operating mode of the unit depending on the selection. The customer input configuration settings are in the Service menu under Set Alarms, Screen 2 of 7. The choices for the customer inputs are shown in Table 7 along with their associated reaction.
Operation 3.7.6 Event Types and Properties Liebert iCOM events are used to inform the user of cooling unit operational status. All events are recorded in the Event Log, which is in the User Menu. The user can change the type (alarm, warn, message) and time delay of some events and can also enable or disable some events. These event settings are in the Service Menu under Set Alarms, pages 3 to 7. If an event has a safety function (high pressure, low pressure, main fan overload, etc.

Operation 3.8 POSSIBLE EVENT NOTIFICATIONS Table 9 lists alarms and warnings that may occur in a cooling unit. When any of these occur, they will appear on the Liebert iCOM Status menu and will be recorded in the Liebert iCOM Event log.
Operation 3.9 Next Maintenance Calculation The next maintenance calculation, as well as the included diagnostics feature, will help run the cooling unit optimally to ensure minimum component stress resulting in maximum reliability. The diagnostics will help the service engineer evaluate the unit’s operation, reading back operational data since the last maintenance. 3.9.
Operation Parameters for Next Maintenance Calculation General Maintenance Settings • Maintenance Frequency—can be set as one to 12 months or to zero, which disables maintenance calculation • Max. Bonus—increases the time to next maintenance with the set value, if all components run optimally (number of starts, average running time) • Max.
Teamwork 4.0 TEAMWORK Unit-2-Unit (U2U) Communications via a private network will allow the following functions to be placed into operation when the requirement exists. The user must install the correct hardware (see 5.0 - Installing a Liebert iCOM Unit-to-Unit Network) and properly program the units for the selected functionality. The Liebert iCOM network can perform the following functions: The Teamwork Mode functions allow for multiple stages of cooling/heating and humidification/dehumidification.
Teamwork The number of available units is calculated like: • In non-standby configuration: all units with fan on • In typical standby function (no cascade): all units with fan on • In cascade mode: all units that could operate (no alarm, which forces the unit to switch off, unit not switched off, etc.) NOTE 1. Proportional actuators (chilled water valve, free-cooling actuator) are driven in parallel in all units. 2.
Teamwork 4.1.4 Teamwork Mode 2 Teamwork Mode 2 is designed to prevent units within a group from working against each other or “fighting.” It is best applied in large rooms with unbalanced heat loads. In Teamwork Mode 2, all parameters are shared equal to Mode 1, and Unit #1 averages all of the available unit sensor readings on the network to define whether there is a cooling, heating, dehumidification or humidification request.
Installing a Liebert iCOM Unit-to-Unit Network 5.0 INSTALLING A LIEBERT ICOM UNIT-TO-UNIT NETWORK Connecting multiple Liebert iCOM-controlled cooling units in an Ethernet Unit-to-Unit (U2U) network enables the units to work together to achieve efficient cooling and humidity control of the conditioned space.
Installing a Liebert iCOM Unit-to-Unit Network 5.3 Wiring for Unit-to-Unit Communications—U2U Cooling units come from the factory-wired for stand-alone operation. Liebert iCOM U2U Ethernet Network The Liebert iCOM U2U network must be isolated from other network traffic. The network switch(es) that connect Liebert iCOM controls need to be dedicated to supporting only Liebert iCOM communication. The U2U network cannot be connected to the building or IT network.
