Intended use
The Control Unit is designed for signal processing of a pressure-sensitive protective
device (PSPD). It evaluates the output signals of sensors with monitoring resistor
8k2. The integrated output signal switching device (OSSD) transmits the evaluated
safety signals directly to the downstream control.
Safety instructions
Ä
Maintain distance
When installing in the switch cabinet, ensure sufficient distance from heat
sources (at least 2 cm).
Ä
Check supply voltage
Check supply voltage. It must correspond with the connecting voltage U
S
on the
type plate.
The Control Unit complies with ISO 13849-1:2006 Category 3 PL e. So that the
safety classification is retained, the downstream control must be of the same or a
higher category.
Ä
Observe protection class
Only use the Control Unit in rooms with a minimum degree of protection of IP54
(e.g. switch cabinet).
Ä
Do not open the Control Unit
Never open, tamper with or alter the Control Unit.
