First off I know this can get very involved so I will attempt to respond with whatever questions you guys have. I know this is a very loaded question, so thank you in advance for any responses.
Disclaimer: I would never assume someone is giving 100% accurate advice, I will double check the work I just need some initial guidance.
So I have been tasked with showing a machine is safe using IFA's SISTEMA software.
This machine has 3 Light Curtains. (simplifying by assuming all same part #)
Operator Load: SL-V60H
Conveyor 1: SL-V60H
Conveyor 2: SL-V60H
All safety Relays are : 2700569

All CR's are
Operator Light Curtain
Output:
Conveyor 1 Light Curtain
Output:
Conveyor 2 Light Curtain
Output:
Used to de-energize Hydraulic motor
Main Safety Relay: (2700569)
Inputs:
Energizes Safety Valve to allow for cylinders to actuate
Hydraulic Pump Safety Dump Valve Relay: (2700569)
Inputs:
Verifies Spool has shifted in Safety Valve
Hydraulic Safety Valve Relay: (2700569)
Inputs:
Safety Power:
So I believe I would need a safety function for:
Because these are so daisy chained together I'm kind of at a loss of how to do this.
I believe the safety function for the hydraulic pump would be:

So I believe I would need a safety function for:
Shutting off Hydraulic Pump
Shutting off Hydraulic Safety Valve
Conv 1 Stop condition
Conv 2 Stop condition
Shutting off Hydraulic Safety Valve
Conv 1 Stop condition
Conv 2 Stop condition
Because these are so daisy chained together I'm kind of at a loss of how to do this.
I believe the safety function for the hydraulic pump would be:
Inputs:
CH1. N.C. E-Stop 1 & N.C. E-Stop 2
CH1. N.C. E-Stop 1 & N.C. E-Stop 2
Controller:CH1. N.C. E-Stop 1 & N.C. E-Stop 2
2700569
Output:700S-CFB
Has dual channel, with edm monitoring which would make it class 3 or possibly 4, is that correct?
