In this case , the weekly schedule of the G-50A will be inv alidated while the data pre viously set with the web monitor will be validated.
40 8. Step 5: Char ging Function of Ener gy Charge Measuring This step is to set the charging function of measuring instr uments to be perf or med by TG-2000A.
41 (2) What is charge? This represents the charge of electric power , gas or water consumed b y each air conditioner or tenant (In the case of using electric power count by PC direct connect (W att Hour Meter (RS-485)), only electric power can be counted).
42 (4) What is the seasonal charge? The electrical power charge can be divided into the summer seasonal charge and normal charge. Because of this, the f ollowing management can be adapted f or example.
43 8.2 Selection of Char ging Function The G-50A system provides the f ollowing 3 methods to calculate the charge by measuring instruments. F or the objectiv e models that can be charged by each method, please ref er to T able 4-3.

70 9.4 Ener gy Saving Contr ol System Design Flow Fo llowing is the outline of the system design flo w for energy sa ving control e xecution. (1) Deter mine the license type.
71 10. Step 7: Selection of Measuring Instruments (1) Measuring instr uments Use measuring instr uments with recommended pulse signals shown in the T able 10-1 below . We also recommend using a watt-hour meter sho wn in the T ab le 10-2 below . ● ● Make sure pulse unit is set in the measuring instruments.
72 (2) P ower consumption PC direct reading system (RS-485WHM) Please use the RS-485 watt-hour meter sho wn in T able 10-3. ● ● Make sure to set the pulse unit of w att-hour meters. Otherwise, the consumption can not be measured correctly thus hindering the nor mal charging function.
73 11. Step 8: General Purpose Equipment Contr ol TG-2000A can control and monitor system equipment. By using general-purpose control functions, you can control and monitor other manuf acturer’ s ai.
74 11.1 Outline PLC will be used to control general-purpose equipment, along with a DI board (DC input unit) and a DO board (transistor output unit). One icon will be shown on the TG-2000A monitor screen to represent one system equipment, and y ou can operate (one shot pulse output), monitor the status , and monitor for error (le vel input).
75 11.2.2 Determine the control items. After you determine the equipment to be connected, define the control items f or each equipment. Fo r instance, whether y ou want to operate the instrument (ON and OFF) and monitor it, including error monitoring, or just watch f or failure (malfunction).
76 11.2.3 PLC assignment After you determine the control items of the connected instrument, assign PLC ter minals. General-purpose control PLC needs to have one DI board and one DO board mounted regardless of the control items. (There are certain restr ictions about the mounting location and others.
77 11.2.5 Setting of TG-2000A After the assignment of ter minals, TG2000A should be configured. F or each general-pur pose instrument, what to be controlled and monitored should be set up in TG-2000A. Number of connected PLC’ s This shows how man y PLC’ s are connected.
