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 evacuate and charge the refrigerant circuit at installation, turn on/off all loads (outputs) for testing, and allows user to check all inputs.

The procedure is as follows:

1- From the main screen select the SERVICE MENU parameters. 2- In the SERVICE MENU screen select the SERVICE icon.

3- Enter password and scroll to MANUAL MODE, select YES with the up key. 4- Now scroll to Fan On and select ON with the up key. The fan must be on to operate loads in this mode. You must turn off the fan and service mode when completed.

The Compressor 1 and 2 selections are for the ON/OFF and RUN, EVACUATE, and CHARGE modes.

When user scrolls to the Compressor 1 or 2 positions in the parameters list he must press enter to select the first item. Enter again will move the cursor to the ON/OFF selection first (far right item) then using the up arrow key the compressor may be turn on and down key will turn off. Now with the cursor on the ON/OFF position, now use the right arrow key to select the RUN, EVACUATE, CHARGE function and the up or down arrow key to make changes. The RUN selection is the normal operating position.

Parameters list is found on pages in Chapter 2

Ethernet uses a bus or star topologyand supports data transfer ratesof 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physicaland lower softwarelayers. Ethernet uses the CSMA/CDaccess method to handle simultaneous demands. It is one of the most widely implemented LAN standards iCOM Controls Training and Service Manual •the type of error checking to be usediCOM Control Training and Service Manual There are a variety of standard protocols from which programmerscan choose. Each has particular advantages and disadvantages; for example, some are simpler than others, some are more reliable, and some are faster. From a userspoint of view, the only interesting aspect about protocols is that your computeror device must supportthe right ones if you want to communicate with other computers. The protocol can be implemented either in hardwareor in softwareiCOM Controls Training and Service Manual Understanding IP Addressing: Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet. An IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255represented in decimal form instead of binary form. For example, the IP address 168.212.226.204 in binary form is:Network Information iCOM Control Training and Service ManualWhat is networking?… HUBS AND SWITCHESUNIT IDENTIFICATION OR ADDRESSING iCOM Controls Training and Service ManualTwisted pair - 10baseT - UTP Cable How To Use The Schematics iCOM Control Training and Service ManualiCOM Controls Training and Service Manual Electrical Schematics182769 Liebert DS iCOM Global Control 8 - 12 Ton iCOM Control Training and Service Manual
