1) If the slave address of AIM-M10 is not set to the default 1, or
the slave Baud is not set to the default 9600, it needs to be set as
the default value.
2) If the communication line with AIM-M10 in the system is not
well connected, check the communication line and confirm
whether the matching resistance is connected properly.
Note: If the above faults occur, interrupt the power to troubleshoot, and adjust the wirings
until everything is normal.
9.3 Settings and debugging
1) When entering the menu settings, ACREL medical IT products need to enter the password. The initial
password of all medical IT products is 0001.
2) After the system is powered on, set the AIM-M10 load current alarm value according to the capacity
of the isolation transformer. The corresponding relations between alarm current and isolation
transformer capacity are: 45A---10kVA, 35A---8kVA, 28A---6.3kVA, 14A---3.15kVA. After you set up,
follow the process step by step to exit and save the setting parameters. The default alarm current
value of the instrument is 35A, if the matching transformer is 8kVA, then this parameter does not
need to be set. 1）
。
3) Communication parameter setting. In order to realize the centralized monitoring function of
multiple sets of insulation monitors through the centralized alarm and display AID150, it is
necessary to set the slave addresses of each AIM-M10 in turn (the master address is used to
communicate with the upper computer, if there is no upper computer, it is not necessary to set it),
and then the communication between the instruments should be connected hand in hand. After setting,
the head and end of the communication bus are connected with a matching resistor of 120Ω (the
resistance must be added, otherwise communication may not be possible). AID150 does not need to
set RS485 communication address. When using AID120 type external alarm and display instrument to
monitor a set of AIM-M10 insulation monitor, the slave address of the insulation monitor should
be 1, and the slave baud rate should be 9600, otherwise it can not communicate.
4) When AID150 is used, the total number of insulation monitors or residual current monitors
connected to RS485 bus should be set first, and the total number should not exceed 16 sets. In AID150,
the setting of this parameter is in the [Comm set] submenu of the menu. The slave address of each
insulation monitor or residual current monitor shall be numbered from 1 to 16 as far as possible.
When the total number exceeds 16 sets, the number of aid150 shall be increased and networking shall
be conducted separately.
