  • Page 18: Operation

    Operation PERATION The Liebert iCOM display provides viewing, trending and configuration capability for Liebert cooling units. All unit settings and parameters can be viewed and adjusted through three menus: User, Ser- vice 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.
  • Page 19 Operation Autorestart When there is a loss of power to the cooling unit and power comes back, the unit will return to its pre- vious 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.
  • Page 20 Operation Chilled Water Units with Variable Fan Speed—EC or Variable Frequency Drives VSD Fan Speed parameter can be found in the Service Menu / Setpoints submenu on page 5 of 6. This menu allows the cooling unit's fan motor speed to be configured and adjusted for a variety of applica- tions.
  • Page 21: General Compressor Requirements

    Operation 3.1.2 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 22: Compressor Timing-Short-Cycle Protection

    This delay may cause a short cycle if there is a very light room load. A short cycle means that the compressor has cycled On and Off 10 times in the past hour. Should this occur, contact your local Emerson representative to adjust the minimum compressor off delay. 3.1.4...
  • Page 23: Mbv Operation After Compressor Is Turned Off

    Operation When Auto BV Control is selected, the motorized ball valve functions as it would be during normal system operation. NOTE Compressor operation will be delayed 30 seconds to allow the motorized ball valve to position itself for initial startup. When Manual BV Control is selected, the user must be careful in setting the MBV position because the ball valves will remain in the position set in the Service menu until the control is switched back to Auto or until a technician changes the valves to another manual position (the motorized ball valve in...
  • Page 24: Temperature Control-Single Source Cooling (No Extra Cooling Coil)

    Operation Temperature Control—Single Source Cooling (No Extra Cooling Coil) 3.2.1 Temperature Proportional Band The control uses the temperature proportional band to determine which operation to perform (cool- ing/heating) and how much capacity to provide. The Temperature Proportional Band is a user-defined range that is divided into two equal parts for cooling and heating.
  • Page 25: Compressor Control

    Operation 3.2.2 Compressor Control Depending on its type, a Liebert Precision Cooling unit may have one or two compressors with or without unloaders or variable capacity. 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 13).
  • Page 26: Figure 15 Two Compressors With Unloaders (Four-Step)

    Operation 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 15).
  • Page 27: Figure 17 Single And Dual Digital Scroll Compressor Activation Points

    Operation On single and dual digital scroll compressor systems, the first compressor is started at 25% calculated output from the temperature proportional band and stopped at 10%. On dual digital scroll compressor systems, the second compressor is started at 35% and stopped at 20%, see Figure 17. When a com- pressor is started, the solenoid is energized longer than it is de-energized to match the call for cooling.
  • Page 28: Chilled Water Control

    Enabling the feedback signal will eliminate the need to drive the valve closed after a loss of power or Unit Off command, decreasing the unit’s restart time. Authorized Emerson personnel should use the following steps to enable the feedback signal: 1.
  • Page 29: Temperature Control-Second Cooling Source

    Operation Chilled water units that contain a motorized ball valve(s) are connected to the control by an analog output. The analog output is driven proportionally to the call for cooling as shown in Figure 19. Larger chill water units may contain two motorized ball valves in which both valves are controlled in parallel.

  • Page 31: Temperature Control-Reheat

    Operation Temperature Control—Reheat If the room air temperature becomes too cold, the control will call for heating. Heating mode is con- trolled by the Temperature Proportional Band, explained in 3.2.1 - Temperature Proportional Band. 3.4.1 Three-Stage Electric, Hot Gas and Hot Water Reheat The Reheat Proportional Band is divided into three equal parts, each representing one reheat stage.
  • Page 32: Figure 22 Two Single-Step Compressors With Scr Reheat Set To Tight Mode

    Operation capacity is provided at 0% calculated output from the Temperature Proportional Band. As the call for cooling increases from 0% to 100%, the reheat capacity is slowly reduced by pulsing the reheat. At 100% call for cooling, the reheat is deactivated and the second single-step compressor is started. As the call for cooling is reduced, the reheat capacity is slowly increased.

  • Page 34: Humidification

    Operation When the return air humidity reaches the end of the proportional band, either 100% or -100%, full dehumidification or full humidification capacity is provided. No operation is performed when a 0% call is calculated. The control varies the call for dehumidifying and humidifying in 1% increments as the return air humidity moves through the proportional band halves.
  • Page 35: Dehumidification

    Operation 3.5.2 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

    Operation Reheat During Dehumidification Hot gas reheat or hot water reheat will start as described in 3.4 - 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.
  • Page 37: Humidity Sensor Reading Control Types

    Operation 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. NOTE The actual air temperature sensor reading is always displayed on the Status menu. The value displayed for the return air humidity sensor reading depends on the Humidity Sensor Control Type (see 3.6.2 - Humidity Sensor Reading Control Types).
