Introduction
Proximity switches or rotary encoders record measured values, which are evaluated in the
speed monitor PNOZ s30. There are 9 monitoring functions (F1 ... F9), which are per-
formed simultaneously.
Up to 16 different parameter sets (P0 ... P15) for the monitoring functions can be selected
via the select inputs.
Configuration of the monitoring functions is menu-driven, using a rotary knob. The outputs
switch depending on the configuration.
An interface is available to connect a contact expansion module PNOZsigma, enabling the
number of outputs to be expanded.
The relay conforms to the following safety criteria:
}
The circuit is redundant with built-in self-monitoring.
}
The safety function remains effective in the case of a component failure.
