Calculation - the system of the management and automation of the protection el. Installations
67 USD 
You need to make a basic electric scheme and make a list of the necessary components (and if possible a project with visualization) of the control and automatic protection of the extruder-grannulator.Electrical components of the extruder:
9 channels of heating control - TENY by 5 kW 380 v.9 channels of cooling control - ventilators 0.3 kW 220 in
The cooling and heating channels are controlled using the Micro 601 PID regulators.Heating through semestral control, cooling through relay.The main drive - the 380v 30 square meters electric engine is controlled through the PC + ampermeter and the frequency meter on the doors of the control box.The second drive is the electric engine 380v 0.75 square meters of control through the PC + frequency meter on the doors of the control box.The principle scheme is simple enough - it requires electric power protection on all connected powers, on separate groups and each device separately.That is, it needs protection on the entire closet, then on each group separately (heating, cooling, on the PID regulators, on the group other weak precision devices) and on each frequency converter separately and on each TEN and ventilator separately.After the protection, the commute devices go:
by 0.Stop button through the magnetic contactor to the entire closet.

3 .Excerpt/excerpt the granulator engine.The Start/Stop button
and 4.Specific input/output of each PID regulator
and 5.Specific inclusion/exclusion of forced inclusion of each zone of cooling (if for any reason the PID has not included the cooling)

It is just horrors. I went to a meeting as much as I could but DO NOT do more than a month what was planned to do in 3 days and do not respond to the message over the last week it is at all beyond the framework of a healthy fool.
