Product description
The PS2 system consists of one operator device implemented in the control cabinet door, and one guide
device for snapping onto the DIN rail. The PS2 system makes it possible for the control cabinet manufacturer
to create a control unit in line with the user's wishes in an affordable manner.
Upon request, the PS2 system's inputs can be configured differently. However, the inputs are configured ex-
works, and cannot be modified afterwards. The fill level is optionally determined via dynamic pressure, bubbler
system, external sensor (4 - 20 mA) or float switch. There are two relay contacts available for triggering the
contactor combinations and four relay contacts available for issuing error reports. Control and configuration
are extremely easy. Switch points, times and various functions are configured using a digital potentiometer. All
values can be queried on the LC display. The eight LEDs indicate operational status and error reports. There
are further keys available for the Manual - 0 - Auto functions.
