Chapter 2 Engineering Work Associated with Operation Change


26

There are two Group command points; "Unit group command (PT1): COPl (Dummy)" and "Group command DI (PT2): SOP (Actual)". It is designed that the Group command is performed by "Unit group command (PT1)" or by "Group command DI (PT2)" if the upper communication is implemented or it is not implemented respectively. (Default setting)

1.1 How to change the setting The Group command operation can be changed as follows: Upper communication implemented (Yes) - => or Upper communication not implemented (No) - => or . To change the operation mode, the shaded portions in the following table should be modified. For example, in order to change =>, Group command DI must be "DEL => ASN", OI operation must be "Enable => Disable", Upper connection information must be "Yes => No".

Basic

Group command DO is used as Group command. (Freeze proofing is not performed.)

ASN DEL No Enable Yes

Group command DI is used as Group command. (Freeze proofing is not performed.)

ASN DEL => ASN No Enable =>

Disable Yes => NoYes

Group command DO is used as Group command. Group command DI is used for Freeze proofing or so.

ASN DEL => ASN

No => Yes Enable

Yes

Basic

Group command DI is used as Group command. (Freeze proofing is not performed.)

ASN ASN No Disable

No

Group command DO is used as Group command. (Freeze proofing is not performed.)

ASN ASN => DEL No Disable =>

Enable No No

Group command DO is used as Group command. Group command DI is used for Freeze proofing or so.

ASN ASN No => Yes

Disable => Enable No

* If OI is not used at the site, it is not required to change.

1) Group command DI Assign/Delete Points can be assigned or deleted by BESS (or Data Setter, PC-MMI).

Important

If Group command DO is deleted and the central control is disabled, the control panel will be error, so the Group command DO must be "assigned" and the central control must be enabled.

2) Global parameter of SW (S of step 9), Freeze proofing Yes/No (GP) panel 4 (Operation management)

Chang it as 0 (No) => 1 (Yes).

Refer to "Chapter 3, 8. panel 4 Operation management" for the detail.

3) OI operation Enable/Disable When Group command is operated by DI only, the Group command operation should be disabled by OI screen touch panel. When you operate the group command (dummy DO) using OI, you have to enable the group command operation on the OI touch panel screen. * If OI is not used at the site, it is not required to change.

If the Group command is used as Dummy DO (operation by OI or Central monitor) and as DI, the Group command OI operation is enabled as shown on the table above (Upper communication: Yes), (Upper communication: No). OI operation Enable/Disable can be altered by PC-MMI.

PC-MMI Operation

The sequence control method is defined by the instrumentation code for PMX-4. (Pump controller, single-pump system chiller controller: Sequential control by flow load, Dual-pump system chiller controller: Sequential control by energy load) The sequence control has three methods; "control by flow", "control by energy", and "control by temperature", these control methods can be changed.

3.1 How to change the method to control by energy, flow 1) Sequence control method change Change the 45th record on the basic parameter. Data Setter Operation Access to the 45th record on (), and enter (: Energy, : Flow) then click . PC-MMI Operation

Keep the service tool opened, select "Search - NC-BUS search" and search PMX-4.

Select PMX-4 and right-click the mouse and select "Basic data" or select "Basic data" from the menu bar.

Select "FIX Changeover", enter (0: Energy, 1: Flow) on the 45th record.

2) Change the point parameter IPD Change the point IPD of "**Start load", "Decrease criteria", "Operating unit total capacity", "Heating capacity", and "Cooling capacity". Set [m3/h or L/min] for flow, [GJ/h or MJ/h] for energy. After the change operation, perform BESS error check.

3. Sequence Control Method Change (Flow/Energy/Supply Water Temp.) - only Chiller Controller -


32

3.2 How to change the method to control by temperature The sequence control by temperature is attained by: - Increase adjustment by the supply water temperature - Decrease adjustment by the return water temperature. By applying dummy load (chiller total capacity) to the sequence control load, units adjustment control by the supply/return water temperature is enabled.

1) Control parameter change Change the MAX global parameter of panel 8 (sequence control load) as -1=>59999.

For the details, refer to "Chapter 3, 12. Panel 8 Sequence Control Load (Flow 1 system) <Item001>", "Chapter 3, 13. Panel 8 Sequence Control Load (Energy 1 system) <Item002>", "Chapter 3, 14. Panel 8 Sequence Control Load (Energy 4 system) <Item003>", "Chapter 3, 15. Panel 8 Sequence Control Load (Flow 1 system) <Item004>".

3.3 Notes • Sequence control method of the pump controller can't be changed. • Sequence control change to temperature can be done for the chiller controller (Single-pump/

Dual-pump). However, performance of the sequence control by temperature will be degraded when number of unit increases, so the number of unit should be limited to 2 or 3.If many units are installed, perform the sequence control with a flow meter equipped.

• The sequence control by energy for the single-pump system chiller controller is disabled at the site where there is less temperature difference since it may cause insufficient flow.

• The dual-pump system chiller controller can be changed to the sequence control by flow. If it is decided to adopt the flow control before ordering, it is better to order the single-pump system chiller controller because of less engineering works.


33

Configuration of the upper communication is defined by the instrumentation code for PMX-4. When a central station is installed at the site where the upper communication is not implemented, in order to connect the PMX-4 to the system, the settings of PMX-4 can be changed from "Upper communication not implemented" to "Implemented" at the site.

In this case, if number of Thermal Source (pump) or control details is to be changed, customization is required because the changes can not be applied at the site. (Only the configuration of the upper communication can be changed from "Not implemented" to "Implemented".)

4.1 How to change the settings The configuration change from "Upper communication not implemented" to "Implemented" is as follows.

1) Change the Point type, UPS setting, and No batch restoration allowed

Check the configuration of the upper communication is "Not implemented" or "Implemented" with the instrumentation sheet, and change the Point type, UPS setting, and No batch restoration allowed. The change point is "Night mode" and "Cooling mode". After the change operation, assign IO, and then perform BESS error check

2) Change the group command settings The usage of the group command differs according to the configuration of the upper communication "Not implemented" or "Implemented".(Not implemented: use it as DI, Implemented: use it as Dummy COP) As shown in this chapter, "1. Group Command Usage Change", change the operation pattern => .

For the details, refer to "Chapter 2, 1. Group Command Usage Change". • Set the "Group command DI(PT2)" as ASN => DEL. • Set the Group command OI operation Enable/Disable as Disable => Enable. • Change the Upper connection information (1BS41) 1: No => 0: Yes.

3) Change power failure related parameter To detect power failure status from the power feeding signal from the upper system, set the followings. • Power supply input setting

Change 1BS37: 17 (Power failure detection by point) => 0 (Power failure detection by power supply signal from the upper controller)

• Power restoration delay time Change 1BS38: 15 => 0 (Upper communication is implemented)

Since capacity of pump does not depend on the outdoor temperature and it hardly require the units adjustment, the Hi limit is set to 0. If the sequence

control decrease point calculation method is (LP:013(NJP))=1, the Lo limit ratio is set equal to the Differential, it is not required to set the Lo limit ratio.

It is an operation gap will be used at the Thermal Source decrease capacity decision. If the sequence control decrease method is "1" (energy saving precedence), the recommended value is 20 % or so. If the sequence control decrease method is "0" (stability precedence), the recommended value is 5 - 10 % or so. When the operating

sequence method is Sequential method/Rotation method/Program method (Sequence control decrease limit operation method = 0), it is used. If Program method (Sequence control decrease limit operation method = 1) selected, set at LP15 - 58.

105

<< General >> When Forced OFF DI is activated, Thermal Source equipments are stopped forcibly. Then the substitute equipments are ON after the waiting effect time has passed. Also while in waiting effect status after the Forced OFF DI was disabled, then the waiting effect time has passed, sequence control will be performed. Therefore this panel enables to follow the load variance while in the waiting effect by doing ON/OFF decision when the Forced OFF DI status is changed.





1 AND V2 0 No.1 ON/OFF decision while Forced off is enabled Set "1" to enable the ON/OFF decision.

3 AND V2 0 No.1 ON/OFF decision while Forced off is disabled Set "1" to enable the ON/OFF decision.

Delay time (Off-delay time) Set the delay time according to the number units that are operated by the Forced OFF DI simultaneously. Calculate the minimum required delay time by the following arithmetic expression. Delay time (sec) ≥ Panel execution cycle (10 sec) + Maximum value of sequential startup and stop x (Maximum number of equipments that are Forced OFF DI operated - 1) Set 40 sec or more to the following value: Sequential startup

(default: 30 sec), sequential stop (default: 30 sec), and Delay time of the Forced OFF DI when maximum number of units is 2 that can be input simultaneously.
