SIEMENS PXM20-E

All values visible in the system can be displayed in accordance with the defined

operator profile. Typical displays:

• Display of current values

• Setpoint and parameter settings

• Maintenance and error messages

• Alarm lists and single alarm messages with acknowledgement option and/or reset

• Time schedulers (7-day schedules and exception programs)

• Plant switching

• Login and password inputs

An integrated collective alarm message system with acoustic and visual indication is

provided.

As the PXM20 operator unit is designed for end-user operation the operating concept

concentrates on the simplest and clearest possible display following intuitive operating

principles rather then displaying as many values as possible.

• Any text is displayed as clear text in the chosen language.

• To ensure a clear orientation for any operator the two top display lines (header

lines) always show which building services system or which function is currently in

operation.

• The basic concept of the operation ensures that it is always possible to select direct,

with the click of a button on the keyboard, the plant information shown on the

relevant line (direct access keys).

• Any settings or modifications (for example in graphics) can be followed direct on the

display (e.g. graphics display for scheduler).

• The basic concept also ensures that all information and help functions can be called

up any time (info key).
