Folks, we are trying to develop standards in developing professional control design submittals....can you give me some ideas on how you do the following
1) symbols ...Temp -pressure or humidity sensors..how do you define these in the symbols page....besides the physical shape do you assign code numbers?
2) system drawing device callouts...assuming you show a device to represent say a temp sensor...do you assign a code to this IE T1-T2..and then a point name ?..do you number these sequentially.....what if you have thermisters and rtd's.....do you use the same code or callout numbers for the same type of sensor from job to job ?....
3) how do you link the sensor device on drawings to the control panel termination locations....so it would be easy for an electrician to install by ?
thank you in advance for any suggestions.....really appreciated
