sweating suction line
what cause a sweating suction line in a split system?
my suction pressure was 68 psi and my high was 224 psi .
Can it be undercharged or overcharged?
dirty indoor coil?
Most of the time it is below the dewpoint and will sweat. That's why the insulation is on it.
Is the suction line insulated?
What baldie said.
Remove those guages, and step away from the unit.
Checking the charge is not a DIY thing.
A suction line will sweat is can even have ice and be OK. As long as the ice goes no farther than the end bell on the compressor it is nothing to really worry about. A little frost on the end bell is just good subcooling for the compressor.

If an uninsulated suction line is below the Outdoor Ambient Temp (OAT) dew point it will condense moisture. Of course, the OAT dew point can vary a great deal; just ignore the sweating issue. (Where is the insulation?)
Forget about a sweating suction line, it is NOT an indication of an incorrect charged system.
Get the airflow right & the Superheat & Subcooling within specifications.
If suction didn`t sweat you wouldn`t need a drain pan.
In my opinion you've left out quite a bit of important information. Whats you indoor metering device (this determines the method for verifying correct refrigerant charge)? Once you've determined method for checking charge, what is the required superheat or subcooling. What are you indoor and outdoor temps (wetbulb and drybulb)? The past few days where I am its been very cool for august (79 degrees high temp) and very dry. I've had 53 degree suction lines that aren't sweating simply because with the low temp and humidity they suction lines are above the dew point.
