Safe monitoring with PSS 4000

In the automation system PSS 4000, the safe monitoring function is completely integrated within the user software. Two different measuring principles, and therefore different functions, can be implemented.

For example, you can monitor up to 8 axes per control system (PSSuniversal PLC or PSSuniversal multi) up to PL e with a compact module and corresponding software blocks – and that's just with one encoder.

You can also implement safe position monitoring in the automation system PSS 4000. Counter modules with software blocks are available for this purpose. Thus, in combination with two (non-safety-related) encoders, you can monitor the safe position of your drives.

• Safe monitoring of up to 8 axes per control system up to PL d
• I/O module can be combined with the control systems PSSuniversal PLC and PSSuniversal multi
• Reduced reaction times, higher productivity
• Errors are minimised and projects can be implemented quickly due to the simple setting of speed functions in the software
• Fast commissioning, maintenance and service due to simple diagnosis of the set limit values and parameters via the tool
• Use of existing encoders
• Realisation of safety functions according to EN 61800-5-2 (up to PL d with just one Sin/Cos encoder, up to PL e with a safe encoder, up to PL e with a combination of encoder and initiator, with additional gear monitoring)

• Safe evaluation of speed, position and standstill using standard rotary encoders
• The safe monitoring function is transferred to the user software
• Higher flexibility due to dynamic limit value monitoring in the application program
• TÜV-approved
• The solution can be universally applied and extended, due to standardised interfaces

• SSR - Safe speed range
• SSM – Safe speed monitor
• SDI – Safe direction
• SOS - Safe operating stop

• SLP - Safe limited position
• SP - Safe position monitoring
