Page 9: Function Description
AND/OR connection The PNOZ e3.1p has two logic inputs S35 (OR) and S36 (AND) for logic connections between several units. Operating modes Dual-channel operation: Earth faults in the input circuit and shorts between the input cir- cuit contacts will be detected. -
Page 10: Installation
You must comply with the idling capacity at safety outputs 14 and 24 (see Technical details [ 25]). Do not connect undesignated terminals. Output Y32 is an auxiliary output, e.g. for communication with a PLC or text display. Operating Manual PNOZ e3.1p | 10 21240-EN-09... -

(on the input circuit) does not overload the proximity switch. The power supply must comply with the regulations for extra low voltages with protective electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410. Terminal Y5 is provided for Pilz-internal diagnostic purposes. Preparing for operation Supply voltage... -

If you do not wish to connect any contacts to the feedback loop, Y6 must be connected to CAUTION! Do not connect the contacts from external contactors in series to the start circuit. Operating Manual PNOZ e3.1p | 12 21240-EN-09... -
Page 13: Logic Connection Between Several Units
Logically linking the units leads to delays when switching on and off (see on-delay and re- sponse time in the Technical details [ 25]). These are added up with each unit that is logically linked (Example 3 [ 18]). Operating Manual PNOZ e3.1p | 13 21240-EN-09... -

The logic inputs are connected to each other as follows: Safety outputs Input circuit Logic inputs S35 and S36 from the PNOZ e3.1p enable additional PNOZelog or PNOZmulti units to be logically AND/OR connected. Input circuit Logic AND + OR... -
Page 15: Examples
In all the application examples, 2 loads may also be connected to the safety outputs. Example 1: Loads are connected to the safety outputs of Unit 1. In addition, a safety output is AND- linked to 4 other PNOZelog units via the logic input S36.
