AM every few milliseconds EEPROM can not keep up to that pace and even if it could it would be used up in a matter of days If you think about how long it would take to make a million changes to the control programming through the front key pad you will see that it would take a very long time to get to use up the life of the EEPROM Adding one of the computer communications options e g 992 993 995 996 changes the picture The speed of computer communications is such that hundreds of instructions can be made in less than a minute In such a situation the million erase write cycles could be used up in a couple of months causing the chip and the control to fail Usually in such a situation the control is under close observation by the host computer It may not be necessary then to have the data written to the EEPROM as it is transitory in nature changing set points for a ramp soak sequence for example Controls equipped with a Serial communications option have a menu item in the Secure menu Star that allows the serial communications to write to RAM Star na The factory default is write to EEPROM Stor YES If your computer system will be making frequent changes to the control we strongly recommend that you select the write to RAM parameter Star na If you are primarily reading from the control there is no need to change the setting For further information on protocols and technical

AUTO MANUAL OPERATION The AUTO MANUAL function allows you to manually adjust the output of the control This is normally used during process setup or start up It can also be used for troubleshooting To switch from AUTO to MANUAL press the DS AUTO MANUAL key and hold for three seconds The MANual indicator will light and the lower display will change from normal to show ing the actual output in percent The value will be the actual percentage of output that was active when the key was pressed This is usually known as bumpless transfer If you wish to change the output while in manual press the UP ARROW or DOWN ARROW keys to change the value and press ENTER to retain it It is important to remember that the value of the display is read as 0 to 100 of the full control output NOT the range between S1OL and S10OH or S2OL and S2OH For example if the set point one output is programmed for 4 to 20 mA S1OL 20 S1OH 100 a reading of 50 in MANUAL represents 10 mA not 12 mA This allows the operator to go above and below the output range to allow for improperly function equipment that may be connected to the control output To return to AUTOmatic control press the ga AUTO MANUAL key again The MANual indicator will go out and the set point will take over However if you want bumpless transfer back to AUTO slowly change the percentage of output until the process variable matches or at least is close to the set point The fu
