Got your PM. It'll take me some time and I'll work on it for you.
Based on your plan for 6 LED indicator lights, I'm thinking that the switches you chose to use are:
Auber Instruments - Selector Switch, 2-Position Maintained 2 NO
- SW4 units.
Is that correct?
Also, what switch are you planning to use for the main power switch - The SW8 Key Switch or something else?
Your contactors have 240V coils. Correct? You already purchased them? Reason I'm asking is that might change your switch configuration and would possibly need additional modules for the control switches. Also do you have 2 or 3 total contactors? Please let me know.
Here's the plan:
240 volt 50 Amp GFI Spa Panel
6/3 with ground conductor
50 Amp main control power contactor with 120 volt coil
Main power switch
4 30 amp breakers
1 20 amp breaker
1 1 amp fuse for E-stop
1 12 pole terminal block
2 2362 PID's
2 Switches to control PID Power
2 40 Amp SSR
2 30 Amp contactors to control element power 240 volt coils
2 Switches to control Element contactors
2 5500 Watt Elements
2 Switches to control pumps
1 E-stop Switch
6 LED's to indicate power for control switches
2 30 Amp 240 volt receptacles
2 20 Amp 120 volt receptacles
