The figures show the connection between the Orion3 Base and the RT9 safety relay/ Pluto B20 safety PLC when the
AOPD is in Manual Reset mode with a reset button connected to the AOPD.
NB: Do not use varistors, RC circuits or LEDs in parallel with the relay inputs or in series with the OSSD outputs.
NB: The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel, but must be used separately
according to the safety requirements of the plant.
If one of these configurations is erroneously used, the device enters the OSSD Error mode (see paragraph
8
NB: Connect both OSSD outputs to the activating device. Failure to connect an OSSD to the activating device
jeopardises the SIL and/or PL of the system that the AOPD controls.
