Thanks a lot guys, just one final thought to discuss:

So the cycle time up means total load time for the compressor, for example If cycle time up and other parameters set as follows:

Cycle time up = 3 sec
Proportional Band = 15 Psi
NZ = 0.5 Psi
SP = 20 Psi
Actual value = 35 Psi

Then Difference = Actual Value – (SP+NZ) = 35-(20+0.5)= 14.5 Psi (for loading)

If Diff < PB Then
Capacity change = (14.5/15) x 3 = 2.89 sec


Therefore, the load solenoid will be ON for 2.89 sec and off for (3-2.89) = 0.1 sec. Is it correct? The above calculation will be valid for 3 sec. Once the 3 seconds elapsed, a new value of suction pressure will be captured and the above calculation will be generated, is it correct also? Or the above calculation will be taking place continuously until the suction pressure meets the SP. The way i understood cycle time is that,there is a cycle time up or down timer that will be resetting automatically once the .acc value becomes equal to .pre value (3 sec in this case), and from the start of the new cycle it will reevaluate the response and actual value.
