Basic Chiller Setup
Press the "NEXT MENU" key and menu 26
(Unit Setup)
will be displayed. Menu 26 has three
screens. This menu is password protected and requires the operator password. Changing the values
in this menu can cause network communications failure.
There are several menus that require resetting the default values for proper unit operation. The setup
procedure will be performed by the startup technician and the information should be recorded for
future use. This following procedure will show how to setup a single compressor
(WSC)
stand-alone
unit without a network.
Set the toggle switch on the face of the MicroTech panel to the stop position. Press the "ALARM"
key under the Category group. This brings up menu 27. Press the "PREV. MENU" key and menu 26
will be displayed. Menu 26 should be the first menu to be modified because the information entered
affects other menus. The following will be in the sequence displayed on the screen. The values
entered will depend upon the unit and the information required should be obtained and recorded
before an attempt is made at inputting the data.
