(a) Selection

following items.

(b) Selecting the pulse unit

1. Restrictions on the pulse input receiving side

2. Selecting the pulse unit

Calculate the total of power supply capacity required for the air-conditioners to be connected.

Maximum operating status of air-conditioner: Estimated overload condition expected in the summer season, for example:

If it is assumed to be the total power consumption @ 1.2;

Example) Provided the total power consumption status = 100 kW and the power factor = 90%

If max. operating status = 100 @ 1.2 = 120 kW, 3-phase, 200 V

I = 120 @ 1,000/(1.732 @ 200 @ 0.9) = 385A

/ The watt-hour meter needs to have a capacity of 400 A.

If we select an oscillation device from Mitsubishi’s products of 400 A:

· K11 type ­ Select the pulse unit 100 kWh/P or 10 kWh/P

· K12 type ­ Select the pulse unit 100 kWh/P or 10 kWh/P or 1 kWh/P

• For a further small pulse unit, consult a watt-hour meter manufacturer.

Check for when the power consumption is 120 kWh (Example)

c If 0.1 kWh/P is selected when the pulse input is the largest: 1,200 P/h = 20 P/min, which means it is 20 pulses/min, and

so this is acceptable.

c If the duty cycle decreases to 1/10 (12 kWh), for example; If 10 kWh/P is selected, 1.2 P/h = 0.02 P/min, which means

that there is no pulse within 10 minutes. It becomes 28.8 pulses for a day. If 1 kWh/P is selected, it is 12 P/h = 0.2 P/

min, which means that there are 2 pulses/10 minutes.

1 pulse a day, it is possible to use 10 kWh/P. However, since it is likely

to produce calculation errors depending on the duty cycle, it is better to use 1 kWh/P.

.User login For owners the fee apportionment for multi machine air conditioners is more complicated and harder to explain to customers. In many cases it’s best to use simple explanations. In addition, consumption for multi machines are calculated based on volume, making it easy for excessive cooling and differences in building load to lead to discrepancies in electricity consumption. These different values are hard to explain. Therefore, it is easier to explain how many horsepower were used for how long.
At this point, recommend [RUN/STOP] registration Both multi machines and single machines use [RUN/STOP] registration. Recommend that separate electricity meters be installed for single machine and multi machine systems. Display every unit of electricity (kW) on the electricity consumption board. For example, register P280H as 28.0. Current operational value = electricity volume @ time of operation, calculated according to the electricity volume ratio.

It is possible to assign two or more meter numbers to one air conditioner’s indoor unit. It is applicable to an air-conditioning

system like a GHP (Gas Heat Pump) system that consumes different energy. It can apply, when measuring an outdoor unit

and each indoor unit with another watt-hour meter. In this case, assign meter number of an outdoor unit to indoor units.

In case of the previous Super Link system, “Unit No.” shows the “Super Link” communication line number (1 – 3) and the indoor unit number (00-47). Input the meter number (1 – 8) without a space into “Meter No.” column.

3 TROUBLESHOOTING
A malfunction has occurred with the unit. The malfunctioning unit is stopped. Contact the shop where the unit was purchased. The shop will need the following information: “unit icon color”, “malfunction situation”, “model name of the malfunctioning unit”, “Error No. (E00)” etc.
A communication problem has occurred. Contact the shop where the unit was purchased. The shop will need the following information: “unit icon color”, “malfunction situation”, “model name of the malfunctioning unit” etc.
Clean the air filter. (See the manual attached to the air conditioning unit for the cleaning method.) Press the filter reset button after cleaning.
Regular inspection is necessary. Contact the shop where the unit was purchased. The shop will need the following information: “maintenance display color”, “unit model name” etc. * The unit number and maintenance display content can be checked on the UNIT INFORMATION screen.
It is possible that there is malfunction due to electrostatic discharge. Turn the power off, then turn it on again (power supply reset). When it does not operate normally with the procedure above, it can be assumed that the unit was damaged, so contact the shop where the unit was purchased with the “malfunction situation”.
· The backlight (illumination) is turned OFF after a fixed period of time to preserve the screen. Touch the screen. (It may take a little time for the display to reappear.)
· It is possible that there is malfunction due to electrostatic discharge. Turn the power off, then turn it on again (power supply reset). When it does not operate normally with the procedure above, it can be assumed that the unit is damaged, so contact the shop where the unit was purchased with the “malfunction situation”.
When multiple units are registered in a group, the settings for the representative unit for the group are displayed. Check the status display for each of the units. Run/Stop displays “Run” if one or more units in the group are running, and it displays “Stop” if all units are stopped.
Check the schedule settings. The group settings that have been scheduled can be changed.
The unit may get warm, but this is not a problem. When the room is hot, it gets warm more readily. Use in an environment where the temperature around it is 40°C or lower.
· If the total operating time in a day is less than 30 minutes, there has been no operation for calculating purposes. Therefore the calculating results may be a little low.
· Even if the air conditioner is not used all day long such as on a holiday, standby electricity is still consumed. If power consumption is allotted to only the operated indoor units on a pro-rated basis, standby electricity consumed on holidays is not included in the calculation result. As a result, the total calculation result becomes different from the actual power consumption. On the other hand, if power consumption of standby electricity is proportionally allotted to all indoor units including those not being operated, the total calculation result coincides with actual power consumption. However, in this case, the power consumption of standby electricity is allotted to not only the tenants actually operating indoor units but also the dummy tenants and the tenants not operating indoor units. This may cause problems among tenants so that this method has not been adopted. If there is any difference between the total calculation result and the actual power consumption, try to reallocate the power consumption to the tenants actually operating indoor units respectively by using the spreadsheet software according to the calculation results.
It is possible that either the definition file has not been saved to the USB memory or there is an error in specifying the folder to be read. Check again and then perform the operation again. If this message appears again, contact the shop where the unit was purchased.
There is a possibility that the USB memory has damaged or the files in the USB memory have damaged. Delete all the files in the USB memory and create them again. If this message appears again, contact the shop where the unit was purchased.
The USB memory may not have been fully inserted. Remove the USB memory, and reinsert it. If this message appears again, it is possible that the USB memory is damaged or the USB memory is not the attachment. Replace it with the bundled USB memory and try the operation again. If this message appears again, contact the shop where the unit was purchased.
