A "warm" start will save allprogrammed information in the <strong>922</strong>'s memory backup. A "cold" start is a "clean"startup condition; all user-programmed information is deleted. Your <strong>Series</strong> <strong>922</strong>leaves the factory programmed for a warm start. DIP Switch #2 selects whetherall SPCLFUNC parameters will be displayed or not. DIP Switch #3 determineswhether the decimal point will be displayed in tenths of units for 0-5V or 4-20mAinput and DIP Switch #4 is for 0-5VDC/0-20mA input or 1-5VDC/4-20mA inputselection. DIP Switch #5 is not used, and DIP Switch #6 is a factory test/calibrateswitch.Changing the Position of a SwitchWhenever you change the position of a DIP switch, follow this procedure:1. Remove power from the <strong>Series</strong> <strong>922</strong>. Turn the front panel screw 90° counterclockwise.2. Grip the front panel bezel and pull it straight out from the control case. Thecontrol chassis will come out of the case as you pull the bezel.3. Set the DIP switch to the position you want.4. Return the control chassis to the case. Be sure you have it orientedcorrectly. It will not fit in upside down, but check just the same. Press firmly,but gently, to seat the chassis.10 WATLOW <strong>Series</strong> <strong>922</strong> <strong>User's</strong> <strong>Manual</strong> Starting Out, Chapter 1
