Hi All,
On our site, we normally use trapped keys for our safety gates, however, for our newest project, I have been told that we will be using AB Guardmaster 440G Spartan Solenoid Interlock Switch - Power to unlock.
I am fairly new to PLC programming and have never programmed anything safety related, and we haven't used these on site before so its not like I can copy any already written code.
How should I go about programming this? Are there any instructions that should be used for the inputs? - eg: Estop etc.
For the output, the plan is for the operator to press a button on the HMI to be able to open the gate while the system is not in a cycle - so is the rung as simple as: button pressed & system not in cycle --> Output on safety card energized (gate open) - or are there any safety related considerations that need to be made?
Thanks
