• Set the proportional time cycle parameter, “TC” to 30 secs. or more. Example 2: • Use of “Z-trap” (manufacturer: Fuji Electric Co.) is recommended to protect the relay against switching surges and to ensure the prod- uct’s long life. Connect it between the contacts of the relay as 120V AC shown in the example below. -

The controller then reads the reaction of these test signals on the An example of proportioning would be a vehicle approaching a stop process. Keep in mind that every process is different and therefore sign at an intersection. If the driver were traveling at 50mph and only every reaction to the test signals is different. - Page 20 Integral Time The derivative action changes the rate of reset or integration propor- tional to the rate of change and lag time of the system. By calculating With the proportional band alone, the process tends to reach equilib- the rate of change of the process and multiplying it by the lag time rium at some point away from the main setpoint.
