In refrigeration control systems, operating convenience should certainly not come off second best. Not only the expert ought to be capable of operating the system; also shop management should have the possibility of intuitively intervening and of accessing information on its status.

The AL 300 operator terminal has been designed for the central parameterisation and operation of E*LDS components. Next to the display of operating data, the AL 300 signals messages and alarms.

The operator terminal offers several operating languages and can be used as an alternative, or in addition, to the system centre. Up to 9 AL 300 operator terminals can be operated together – in the store manager’s office, the building services centre or the headquarters, i.e. at any place where current status information on the refrigeration system matters.

The operator terminal is the system centre’s smaller brother and is, like all other components, connected to the CAN bus. In contrast to the system centre, the operator terminal is not equipped with an interface for the connection of a laptop computer. It does not have a data archive memory of its own, but can be used to access the system centre’s data memory.

The AL 300 operator terminal is available in two versions, one for installation in the switch cabinet door, the other for wall mounting.
