The time set -up function comes in two types, date/time set -ups and time monitor set -ups .
Function Contents
Date/time set -up Sets the date/time of all G-50A units connected to the PC (personal computer)
as soon as the PC date/time is set.
Time monitor Confirms the difference in time between the time reference machine (G-50
No.1) of this system and all G-50A units except for No. 1 and the PC.
* PC means a personal computer on which the integrated software TG -2000A operates.
Set the date/time.
[Procedure]
1) Select [Time set -up] button.
Click the [Time set-up] button located in the system
setting group on the initial window.
2) Select the [Date/time set -up] button.
Click the [Date/time set-up] button on the time set-up
select screen.
3) Select the part you want to change.
Click “Year”, “Month”, “Day”, “Hour”, “Minute”, or
“Second” you want to change.
4) Select the “ / ” button.

For this system, the G-50A main unit collects the operation data of the air conditioner from the indoor unit
to which the G-50A is connected in order to calculate the air-conditioning charge on the basis of the data
using the set capacity and charge unit cost. When there is a difference in time between the G-50A main
unit and PC on which the integrated centralized control software TG -2000A operates, it becomes unable
to correctly execute the calculation.
Consequently, the time adjustment is executed everyday between the integrated software and G-50A to
correct the difference in time between each unit. (The time adjustment is based on the No.01 G-50A.)
Because of the reasons shown above, it is not basically necessary for this system to adjust the time
manually, except for the initial setting. Therefore, when the charging function is used, do not adjust the
time unnecessarily.
Note:
• The alarm message shown in the following
illustration is displayed when the [Date/time
set -up] button is clicked.
