2-1 Operating Manual: PSS 3075-3 Series
Overview
A PSS from the PSS 3075-3 series is a complete programmable safety
system in a single unit.
The device descriptions provide information on their function.
The description are made up of combinations of letters and numbers.
• The PSS 3075-3 contains:
- Power supply
- CPU
- 48 digital inputs, 6 of which are alarm inputs
- 18 single-pole outputs, 4 of which are test pulse outputs
- 9 dual-pole outputs
- Programming device interface
(combined RS 232/RS 485 interface)
- User interface
(combined RS 232/RS 485 interface)
• In addition to the features on the PSS 3075-3, the PSS SB 3075-3
contains:
- SafetyBUS p-interface
Additional functions
• DP-S
Interface for connection to PROFIBUS-DP
• ETH-2
Interface for connection to Ethernet
• CANopen
Interface for connection to CANopen
• SE
The name "SE“ can be found only on the type label of the PSS (e. g. PSS
SB 3075-3 ETH-2 SE). It is a PSS that is identical to the corresponding
serial device (e. g. PSS SB 3075-3 ETH-2). The PSS however is intended
for use with SafetyEYE and therefore delivered with a preinstalled user
program.
• NR
Safety system without battery
Operation without a battery results in the following restrictions:
- FS section: Remanant data blocks cannot be used.
- ST section: A general reset is performed each time the section
switches from STOP-RUN.
- Each time the PSS is restarted (voltage switched off and then on
again), the system time is reset to zero.
