"CLEAR" ROUTINE
A "CLEAR" routine is available that will clear all data, flags, and all other current information from memory. Since MEMORY is battery backed up, turning power off does not clear all fields. A great deal of information is intentionally held for later use. A "CLEAR" routine will clear all RAM data and start with the information stored in the EEPROM. This is the same data that existed when new or data that you may have intentionally saved earlier. All current rate calibration numbers that the unit has "learned" will be overwritten.
To execute a "CLEAR", hold down the "CE" key while turning POWER ON, then release. When done correctly, the display will say ( CLEAR ).
CLEAR does not clear EEPROM information but instead loads EEPROM into RAM. Load Cell weight calibration numbers are NOT lost.
(To load EEPROM with correct RAM information, see KEYPAD, *23)
CLEAR ALL - RESTART
The same as the CLEAR, above, but EEPROM information is also cleared. There are only TWO times when you want to do a CLEAR ALL.
1.When a NEW PROGRAM CHIP has been installed.
New chips often have different PARAMETER table layouts. Information may reside in memory locations that do not match the new program. CLEAR ALL - RESTART fixes this.
2.When all else fails.
CLEAR ALL - RESTART will sometimes fix problems that the simple CLEAR routine misses.
The keys to press on power up are VIEW, BTCH, and EXIT (Top row, left, center, and right). Hold all three down as power is turned on, then release. When done correctly the display will say (CLEARALL).
LOAD CELL calibration WILL be lost. You will have to follow the Load Cell calibration procedure given in this manual.
Since parameter table information is lost, you will want to reenter parameters that were previously modified. See BRIEF EXPLANATION of PARAMETERS for a quick review of which ones might have been changed.
Be certain that your unit displays the proper MODEL number when you turn on power. If not, see SELECTING CORRECT MODEL, page 14.
CORE DUMP
During production or between cycles, the controller can be forced to print a CORE DUMP of Memory. This is helpful to us when elusive problems are occurring related to non predictable environmental problems. If you are having reoccurring problems, we may ask you to use this routine during production to help us diagnose the problem.
To obtain a MEMORY CORE DUMP, have a printer connected. Press three keys at the same time; the PARA, FULL, and ALRM keys; bottom row, left center and right.
