Introduction

This Special Instruction provides information about configuring the Active Power Control (APC) operating parameter that is called "APC Not Configured". The "APC Not Configured" operating parameter was not used previously.

The operating parameter will be set to "1" as the default. The default setting of "1" means that the APC will not be configured when the unit is shipped from the factory. Due to this change, a service technician will need to contact Caterpillar in order to obtain a "engineering level password". The password is required for the starting procedure of the unit and in order to change the operating parameter.

Important Safety Information

Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs.

A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools in order to perform these functions properly.

Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard.

Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. If a tool, a procedure, a work method, or operating technique that is not specifically recommended by Caterpillar is used, ensure that it is safe for you and for other people to use.

Ensure that the product will not be damaged or the product will be made unsafe by the operation, lubrication, maintenance, or the repair procedures that are used.

Connect a Personal Computer (PC) to the UPS

The following instructions explain the process in order to establish a serial connection from a PC to the UPS.

Single Module System (SMS)

1. Place the system in a de-energized state. Refer to the shutdown procedure that is in Systems Operation Testing and Adjusting, RENR2476, "SMS System Shutdown".

2. Open the left cabinet door (2) and the right (3) cabinet door.

   Refer to Illustration 1 and Illustration 2.

3. Connect a PC to the RS232/RS485 "J1" port (18) that is located on the System Input/Output and Isolation Board. Refer to Illustration 3.

   Note: Ensure that jumper "Jmp 1" (17), that is located on the System Input/Output and Isolation Board, is in the correct position. The lower side must be used for RS232 applications and the higher side must be used for RS485 applications. Refer to Illustration 3 and Illustration 4.

Common

1. Energize the system according to the "SMS System Startup" or the "MMS System Startup" procedures that are in Systems Operation Testing and Adjusting, RENR2476.

2. Turn on the PC.

3. Double click the CSView/UPSView icon that is on the PC desktop in order to start the CSView/UPSView software.

4. Click "PC Settings" on the menu bar. A drop-down menu will appear.

5. Click "Settings". The "CSView/UPS View Connection Settings" dialog will open.

6. Select the "Direct Connect (serial)" button.

7. Select the PC COM port for the serial connection. Check the baud rate. The "Detailed MMU telemetry" button must be checked.

8. Select the "Serial/Modem Port Number" that is appropriate for the PC.

9. Select the desired "Serial/Modem Baud Rate". The default baud rate is 38400.
