* Be sure to set the current time on AG-150A/G-50A and PLC at the initial settings
before starting the operation.
Time monitor Confirms the difference in time between the time reference machine
(AG-150A/G-50A No.1) of this system and all AG-150A/G-50A units and PLCs

<Precautions for using this function>
Basically with this system, the time does not need to be adjusted manually, except for the first time.
(Excluding when correcting an error in the time.) When using the power apportioning billing function, do
not adjust the time needlessly.
Never change the date after starting the power apportioning billing function.
[Description]
With this system, the air conditioner operation data is collected from the AG-150A/G-50A main unit and
the electric amount data is collected from the PLC. The air-conditioning charges are calculated based on
this data using the various amounts and unit prices set in this integrated centralized control software
(TG-2000A). When there is a difference in time between the PLC or AG-150A/G-50A main unit and PC
on which the integrated centralized control software TG-2000A operates, it becomes unable to correctl
y
execute the calculation.
Thus, TG-2000A, AG-150A/G-50A and PLC times are adjusted each day to correct any time erro
r
between the devices. (The time adjustment is based on the No.1 AG-150A/G-50A.)
