Handling the device 6.10 Control locations and priorities Note: if external control by analogue interface is activated (pin REMOTE = low) while the battery test is running, the Control locations are the locations from where the device test is aborted. After external control has left again and if is controlled.
Handling the device 6.12 Functions of the terminal System Bus 6.12.4 Remote sense The remote sense feature is described in section “5. 6.12.1 Two-quadrants operation Installation”. The Share Bus pin (only usable in combination with the power supplies PS9000 and PSI9000) can be used to 6.12.5 Pin assignment of terminal System Bus set up a system for two-quadrants operation.
