iCOM Controls Training and Service Manual Chapter 1 Temperature and Humidity Control Programs This section provides details on how your Liebert iCOM control responds to the user programmed inputs values and room co nditions. Refer to this section when you need specific information control operati on.
iCOM Control Training and Service Manual untrue type of statement is not used. T he consideration now is how to set the input value into a membership set, qualify this membership with rules, then decide on the output consequence for action. It is not really that simple, but it is basically how it works.
iCOM Controls Training and Service Manual more efficient and precise for most applications, but system performance based on room conditions is not as predictable as standard approaches that use a fixed equation.
iCOM Control Training and Service Manual The integral (I) term is determined by tw o things: the difference between the return air temperature and control set point and t he amount of time this difference has existed. This term is expressed in % cooling (heating) desired for each minute and degree above (below) the set point.
iCOM Controls Training and Service Manual A suggested tuning procedure is as follows: 1. Initially adjust the integral and de rivative settings to 0% / degree-min and 0% / degree / min.

iCOM Control Training and Service Manual If the off time is less than 15 hours (or us er programmed value) the pre-fill program is bypassed and the infrared lamps and water valve are activated at the same time to fill the pan to the proper water level and initiate humidification.
iCOM Controls Training and Service Manual Dehumidification Operation The Relative Humidity control program is used to illustrate the dehumidification operation in the following examples. T he basic dehumidification control band is established at the humidity set point with the length equal to ½ of the programmed humidity proportional band value.
iCOM Control Training and Service Manual Note: in the above example that the c ontrol band begins at t he 50% humidity set point and has a length of 4%, which is ½ of the programmed humidity proportional band value. As the return air humidity increases, dehum idification operation is activated at 54%RH or 100% of the dehumidification control band.
iCOM Controls Training and Service Manual The humidity controller activates the firs t stage of dehumidification operation when the return air humidity level increases to 50% of the humidity pr oportional band. The second stage of dehumidif ication is activated when the return air humidity level increases to 100% of t he humidity proportional band.
iCOM Control Training and Service Manual When the return air humidity level decreases to 52%RH or 50% of the dehumidification control band the second dehum idification stage is deactivated.
iCOM Controls Training and Service Manual dehumidification process. T he end user can choose to se lect from the following selections: Parameter Operation No No electric reheat allowed during compressorized dehumidification operation. Normal Electric reheat operates as normal.
iCOM Control Training and Service Manual Additional Programs Start The unit fan is activated. The unit can be switched on/ off from 2 inputs: 1. Remote on/ off input (RSD – Remote Shutdown Device) 2. Display button Note: Switches 1 and 2 are in series; the unit will start only if bot h switches are in the on position.
iCOM Controls Training and Service Manual Fan Alarm / Fan settings The fan operation is controlled by two (2) digital devices: the Loss of Airflow differential pressure switch and the Main fan Overload motor protection. The time delay at the unit start is always 5 seconds shorter than the control delay.
iCOM Control Training and Service Manual The Startup and Freeze Protection Program The sequence for the call for cooling with the program features is as follows: The need for cooling is defined by the cont rol setting for the temperature setpoint, proportional band, and deadband (if us ed).
iCOM Controls Training and Service Manual during the second time frame the cooli ng process locks off and will require a power off sequence. Next Maintenance Calculation Foreword The next maintenance calculation will help r un the Liebert Environmental unit in an optimum way, to ensure minimum co mponents stress resulting in increased reliability.
iCOM Control Training and Service Manual The control always takes the component wit h the most on/ off (cycling) as the reference component, which asking for the nearest maintenance (example: if the fan runs continuously, but the compressor switches on/off all the time, the next maintenance will be calculat ed from the compressor).
iCOM Controls Training and Service Manual Starts per Day Optimum: the number of individual component starts that is considered as good or optimum. To be set by Service Engineer. Starts per Day Worst: the number of individual co mponent starts that is considered as “hunting” or worst case .
iCOM Control Training and Service Manual Freecooling and Dual cooling will operate in the same manner as chilled water with the supervision of the Supply Limit, agai n showing different valve position.

iCOM Control Training and Service Manual 115 The temperature sensor senses a rise in temperature. The rise is transmitted to the C entral P rocessing U nit (CPU). The CPU looks into its memory for information and instructions on what to do with the rise in temperature.
iCOM Controls Training and Service Manual 116 BASIC OPERATION OF THE TRIAC To better understand the operatio n of the triac, we need to look at the movement of electrons in a special type of material used in electronics. Here we have a semiconductor material with what is called a depletion region.
iCOM Control Training and Service Manual 117 The triacs that Liebert uses are standard in the industry and are rated at a 2-amp capacity. You can check these devices for proper operation while they are connected in the circuit. If the load is removed from the device, you can get a false reading from the meter.
iCOM Controls Training and Service Manual 118 Basic Operation of the Opto-Isolator The purpose of the opto-isolator is to prov ide isolation of two voltage sources. This allows a DC voltage source to activa te an AC voltage load device or allows an AC voltage source to provide a DC signal.
iCOM Control Training and Service Manual 119 Troubleshooting the Output Opto-Isolator The opto-isolator IC chips used in these circ uits are the H11J (out put) devices. The drawing shows the pin location for co mponent checks on the output opto. The indented circle in the upper left hand corner of this chip indicates the location of Pin 1.

iCOM Controls Training and Service Manual Note: Use Pin 5 on the input opto-isolator with reference to the V- terminal for voltage check. The vo ltage level is 5 VDC.
iCOM Control Training and Service Manual iCOM Diagnostics / Service Mode Program The iCOM controller has a valuable tool built into software under the SERVICE MENU . This program allows the user to ev acuate and charge the refrigerant circuit at installation, turn on/off all loads (outputs) for testing, and allows user to check all inputs.
iCOM Controls Training and Service Manual Basic Troubleshooting Steps: Example: Unit load is not energizing. Programming: 1. Read and record all program parameter values.
iCOM Control Training and Service Manual 2. If the programming is correct and t he output opto-isolat or is functioning properly but the load device is not acti vated the next step is to check the triac and hard wiring to the load device.
