13. System Operation Precautions

The following describes the precautions to be taken when operating the system. Always read this section before using the system.

13.1 Usage Right

Use this program based on agreement to the following usage rights.

13.2 Operation and Setting Precautions

(1) System configuration and charge system setting changes

- When using the charge function, always carry out the settlement of accounts operation before changing the system configuration and charge system settings.

- When the system configuration was changed, also change or check the charge system settings.

(2) Serial port setting changes

- When using the charge function, carry out settlement of accounts operation before changing the serial port setting.

(3) Time setting

- Do not change the time setting except during test operation. When the charge function is used, the air-conditioning charge is affected.

- When using the charge function, there are times when the time can not be changed.

- While using MJ-310E, never use the Windows “Date and Time Properties”. While MJ-310E is running, do not use Windows Date and time properties.

(4) Fire alarm stop function

- When a failure occurs at the personal computer, I/O board, or a system equipment, the fire alarm stop function may not operate.

- While fire alarm stop is operating, a message box is displayed and man-machine running operation cannot be performed. However, when the message box is cleared intentionally, man-machine running operation is enabled, but do not perform the running operation.

13.3 Air-conditioning Charge Precautions

(1) Using the charge function

- When using this program’s charge function, we recommend that you consent to “Collect air-conditioning charges (including temporary action when failure occurs) by proportional division calculation considered by operation status.” by individual contract with the building owner.

- UPS equipment is recommended to prevent MJ-310E stoppage and data loss, etc. when a power failure or momentary interruption occurs.

- Storing the air-conditioning charge result (block and watt hour meter units) to a device than this personal computer is recommended. (For example, print the air-conditioning charge results on paper and store them.)

(2) Air-conditioning charge calculation (proportional division)

- This is our unique method which makes judgment from the operating status of the air conditioners and proportionally divides the total electric power. Therefore, calculation is not carried out by installing a watt hour meter at the power supply of each air conditioner. This method cannot be used in applications which require a calculation method such that a watt hour meter is installed at each air conditioner.

- When a system abnormality occurs, postpone proportional division calculation to the next day or do not perform proportional division calculation. When you want to correct the proportional division data, use the Charge data maintenance or Remedial apportioning function.

- Since the air-conditioning charge is calculated in block or watt hour meter units, indoor units that are not registered in the charge block are not reflected in the air-conditioning charge.

- Charge block units air-conditioning charge does not include the electric power used by watt hour meter units K controller, A controller OA processing unit, etc. Use the watt hour meter units Air-conditioning energy monitoring display.

- There is an error due to the digits not displayed in the air-conditioning charge calculation results. There is also the possibility of an error of approximately 0.00005 kWh or less in the proportional division.

(3) System change

- When changing the system configuration and charge system settings, carry out settlement of accounts from the day after the settlement of accounts day up to yesterday. For settlement of accounts for the current month, total and use the air-conditioning charge calculated before and after the change. Add the basic charge because the calculated air-conditioning charge total does not include the basic charge.

Mitsubishi Electric Corporation and its suppliers are not responsible for incidental, secondary, or special damage to the user even if notified of the possibility of that type of damage by the seller. They are also not responsible for claims of rights of third parties.

13.4 Others

(1) WindowsNT/Windows 2000 (rebooting)

- Periodically (about once a week) terminate this program and Windows NT/2000 and reboot. Windows NT/2000 generally conceals obstructions to continuous operation for a long time. End and reboot it to minimize the affect on MJ-310E operation.

- An automatic reboot function can be set at this program, but there are cases where automatic reboot cannot restart MJ310E. Therefore, we recommend that you manually terminate this program and Windows NT/2000 and reboot.

(2) Windows (task bar)

- Do not use the Windows task bar during MJ-310E operation.

(3) Printer output

- When using this system with a printer, always turn on the printer power and replenish the paper so that printing can be performed. When printing is not possible, a “Cannot print” message is displayed.
