Page 56: Chapter 6 Configurations
CHAPTER 6– CONFIGURATIONS Chapter Chapter 6 Configurations Switch Access Control The MultiLoad II contains switches which limit menu and configuration access. These switches limit users from accessing Program Mode, as well as from changing Weights and Measures controlled parameters. In Program Mode, the operator has access to the following: The Configuration Menu parameters. -
Page 57: Magnetic Bolts Program / W&M Switches (Current)
CHAPTER 6– CONFIGURATIONS Depending on the date of manufacture, the MultiLoad II may have one of three types of external switch design. All can be sealed and locked to prevent access to Program Mode and to prevent changes of Weights and Measures controlled parameters. 6.1.1.1 Magnetic Bolts Program / W&M Switches (current) This design is the most current and can be found on all new units. -
Page 58: Single Rotary Program / W&M Switch (Obsolete)
CHAPTER 6– CONFIGURATIONS 6.1.1.3 Single Rotary Program / W&M Switch (obsolete) This design consists of a single 3-position external rotary switch with two individual covers which may be locked and sealed with a wire and lead seal. The covers limit the switch rotation to three positions: A - Two covers closed: Program access is denied and Weights and Measures access is denied. -
Page 59: Internal Switch Access Control
CHAPTER 6– CONFIGURATIONS Internal Switch Access Control Two DIP switches on the CPU board also provide the closure of the program mode / W&M switch contacts. When the MultiLoad II/ RCU II does not have the external Program Mode / W&M switch installed, it is necessary to use these DIP switches on the CPU board to enable program mode and W&M access. -
Page 60: Menus And Screens
CHAPTER 6– CONFIGURATIONS Numeric keys (1 through 9 and 0) are used to enter numeric data. Alpha keys are used to enter text, and also to select/deselect alpha character entry. The CLR key is used to clear data entered in error; this is a backspace key erasing characters as the cursor moves backwards. -
