The examination can be conducted sequentially in the following order according to the wiring diagrams shown in section 5.4 of this manual: (1) Check whether each four-piece set constitutes an independent IT distribution system, and ensure that the current, resistance and temperature signals monitored by each insulation monitor are connected... -
Page 30: Settings And Debugging
9.3 Settings and Debugging (1) Acrel medical IT products need to enter a password when entering the menu settings, and the initial password for medical IT products is 0001. (2) Rated current setting. After the system is powered on, set the AIM-M10 load current alarm value according to the capacity of the isolation transformer. - Page 31 (4) System number setting. When AID150 is connected to N insulation monitors, it is necessary to set the "number of systems" in the AID150 settings to N. When the number of insulation monitors is more than 16, AID150 should be increased for network monitoring. (5) Communication view and debugging.
