  • Page 20: General Compressor Requirements

    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.

  • Page 21: Compressor Timing-Units With Two Compressors

    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 tempera- ture threshold, the compressor will be locked out for at least 30 minutes and an alarm will be annun- ciated.

  • Page 22: Motorized Ball Valve In Digital Scroll Units

    Each compressor has one motorized ball valve that is driven by the analog output of the Liebert iCOM control board based on pressure. If there is a call for cooling, the compressor start is delayed by a 30- second timer.

  • Page 23: Temperature Control-Single Source Cooling (No Extra Cooling Coil)

    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 (cool- ing/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.

  • Page 24: Compressor Control

    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 propor- tional band and stopped at 0% (see Figure 12).

  • Page 25: Figure 14 Two Compressors With Unloaders (Four-Step)

    Two Compressors With Unloaders—Four-Step The first two-step compressor is started unloaded at 33% calculated output from the temperature pro- portional 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).

  • Page 26: Figure 15 Digital Scroll Capacity Modulation, 10-100% Variable

    Digital Scroll Compressors A compressor with a suction cutoff unloader can only modulate its capacity between two distinct lev- els: 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.

  • Page 27: Chilled Water Control

    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%.

  • Page 28: Figure 18 Second Cooling Source And Compressorized Cooling

    The Value setting is the factory default setting on free-cooling and dual cooling units. If the tempera- ture 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).

  • Page 29: Temperature Control-Reheat

    ™ GLYCOOL Cooling—Free-Cooling When GLYCOOL cooling is available, the temperature control will calculate a total cooling require- ment 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).

  • Page 31: Scr Reheat

    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.

  • Page 32: Figure 21 Two Single-Step Compressors With Scr Reheat Set To Standard Mode

    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 cool- ing as described in 3.3.2 - Compressor Control.

  • Page 33: Humidity Control

    Humidity Control The control uses the humidity proportional band to determine which operation to perform (dehumidi- fication/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.

  • Page 34: Humidification

    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 humid- ifiers cannot be driven in proportional mode.

  • Page 35: Dehumidification

    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.

  • Page 36: Control Types

    3.7.1 Temperature and Humidity Control Types The Liebert iCOM control has four Temperature and Humidity Control Types: Proportional, PI and Intelligent. Each control type affects the timing and intensity of the cooling/heating and humidify- ing/dehumidifying operations. The Control Type parameter is in the Service menu under Setpoints.

  • Page 37: Humidity Sensor Reading Control Types

    3.7.2 Humidity Sensor Reading Control Types The Liebert iCOM control has three humidity sensor control types: Relative, Compensated and Pre- dictive. The humidity sensor control adjusts how the Temperature and Humidity Control determines the percent requirement for humidification/dehumidification. The humidity sensor control type parameter, Humidity Control Type, is in both the User and Service menus under Setpoints.

  • Page 38: Supply Limit-Optional

    3.7.3 Supply Limit—Optional Chilled water units may be ordered with an additional sensor for monitoring the supply air tempera- ture. This sensor maintains the minimum air temperature under a raised floor to help prevent con- densation 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.

  • Page 39: User Inputs / Customer Inputs

    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.

  • Page 40: Event Types And Properties

    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.

  • Page 43: Next Maintenance Calculation

    To calculate wellness, Liebert iCOM keeps a running total of component working hours and the num- ber of times it has been started. Liebert iCOM relates that data to the optimum/maximum starts per hour. Accordingly, Liebert iCOM will increase or decrease the time before the next service call will be needed.

  • Page 45: 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.

  • Page 46: Figure 23 Teamwork Mode 1 With Two Cooling Units

    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.

  • Page 47: Teamwork Mode 2

    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.
