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.

Operation 4-
The speed monitor can independently monitor two axes for standstill,
speed and direction of rotation. The speed monitor signals the status of
the monitored values to the base unit. Depending on the safety circuit
loaded, the values can be transferred from the base unit, e.g. to a relay
output on the safety system. Incremental encoders and/or proximity de-
tectors can be used to record the values.
The configuration of the speed monitor is described in detail in the
PNOZmulti Configurator's online help.
