  • Page 9: Function Description

    AND/OR connection The PNOZ e2.2p has two logic inputs S35 (OR) and S36 (AND) for logic connections between several units. Operating modes Automatic start: Unit is active once the input circuit has been closed within the simultan- eity period.

  • Page 10: Installation

    The unit and the input circuits must always be supplied by a single power supply. The connection cables between the PNOZ e2.2p and the pushbuttons should not be laid directly next to power cables, otherwise inductive and capacitive interference coup- ling can result.

  • Page 11: Preparing For Operation

    The power supply must comply with the regulations for extra low voltages with protect- ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410. Ensure the wiring and EMC requirements of EN 60204-1 are met. Terminal Y5 is provided for Pilz-internal diagnostic purposes. Preparing for operation Supply voltage...
