8-1 Touchscreen Interface Introduction (MMI)

The Advanced touchscreen interfaces let you control your SCW

Series central chilling station. You can do such things as:

• Control compressors and optional pumps

• View current statuses of operation, such as pressures, temperatures, and capacities

• Handle alarm conditions

The sections in this chapter list special instructions for operating either touchscreen interfaces.

Note: The screens shown in this chapter are sample screens. Actual screen representations may be slightly different in appearance, but are no different in operation. Also, the PLC is configured based on options and system configuration at the time of order. These screens are the basic ones to startup the chiller.
