Functions
5 - 2 Detailed Explanation of Functions
5 - 2 - 1 Monitoring
(1) Air conditioner status monitoring (Air conditioners that can handle Daikin’s DIII-NET)
Allows you to know the detailed operating status such as running/stopped status, temperature setting, operating mode, the occurrence and content of
errors and filter sign for each air conditioner targeted for monitoring.
The occurrences and the contents of errors are displayed in the error message area. When an error occurs on an air conditioner targeted for monitoring,
or the management item icon flashes. You can set a buzzer notification of the occurrences of errors and have the printer automatically printout of the
contents of the errors.
Management points: 1 indoor unit = 1 item
The number of management items of equipment connected to DIII-NET, with the total number of air conditioners is 256 /(per 1 iPU unit)
When expanding to the maximum number: 1,024 items/(when 4 iPUs are connected)
The number of management items can be fewer than those listed above depending on the number of outdoor unit in the air conditioning system.
*Refer to our D-BACS Design Guide for details regarding the method for connecting air conditioners that can handle DIII-NET and the restrictions on
the number of units.
(2) Cumulated Value Upper Limit Monitoring
Prints a warning with the daily report of the contents when the cumulated values of the operating time and the start/stop count exceed the set upper
limit values.
The Result: General standards for maintenance of the facility’s equipment and replacement periods are clarified, therefore allowing for planned
maintenance thereby enabling you to expect a reduction of overall maintenance costs.
(3) Continuous Operating Time Limit Monitoring
Displays a fault when a single continuous operating time for the facility equipment exceeds the set upper limit. You can set the buzzer to ring and/or
the printer to automatically print when an error occurs.
You can set the time limit up to a range of 8 digits in one second intervals for each item to control.
The Result: Prevents idling or burnout by issuing an abnormality when the operation of facilities exceed prescribed time or normal operation.
(4) Power Failure Monitoring
You can set the error display and/or buzzer ring for power failures.
Power failures are determined by the power failure signal from a UPS (uninterruptible power supply device.)
(A UPS is connected to the intelligent Manager monitoring system PC and the iPU.)
Operation data is automatically saved when there is a power failure. The system is automatically shutdown approximately 10 minutes later.
