(1) Relay Module on the GSC+ Control
(2) AUX terminal strip.
(3) 152-7143 GSC Data Cable
(4) Personal Computer.
(5) 160-0140 PC/COMM Adapter Cable (formerly 7X-7425)
(6) 160-0133 Data Link Cable (formerly 139-4166
(7) 171-4401 Communication Adapter (formerly 7X-1701) Note: This procedure is for Generator Set Control + that is mounted in a EMCP II+ Panel. 24DCV must be available from the panel.
Verify that the generator set is not running. Turn OFF the power to the EMCP II+ panel by disconnecting the negative terminal of the battery.
Connect the communication adapter to the PC by using the 160-0141 PC/COMM Adapter Cable.
Connect the 160-0133 Data Link Cable to the "Data Link" port on the communication adapter.
Connect 152-7143 GSC Data Cable to the opposite end of the 160-0133 Data Link Cable.
Connect the "Data+" and "Data-" spade terminals of the cable to the appropriate terminals in the AUX terminal strip. The AUX terminal strip is located inside the EMCP II+ Panel. Connect the "Power+" spade terminal to "RM1" of the relay module on the GSC+. Connect the "Power-" spade terminal to "RM28" of the relay module on the GSC+. Note: For a switchgear conversion that contains the GSC+ control, the connection point for the "Data+" wire is GSC-19 on the 40 pin connector of the GSC+. The connection point for the "Data-" wire is at GSC- 20 on the 40 pin connector of the GSC+. The spade terminals that are on the harness for these wires need to be replaced with two 8T-8730 Connector Socket. After the terminals have been replaced, the modufied portion of the harness can be removed from the 40 pin connector by using the 121-9588 Wire Removal Tool. Contact GSC-2 and GSC-39 must be jumpered together.
Set the engine control switch (ECS) to OFF/RESET. Connect the battery to the electrical system again. Then, turn the ECS to the COOL/STOP position.
Verify that the GSC+ and the communication adapter are receiving power.
Turn on the PC. The operating system on the computer must finish loading. Flash Update Procedure
Note: Before starting this procedure, record setpoints P015, P016, and P026.
Obtain a flash file copy on a floppy disk or a CD-ROM. See Special Instruction, "Accessing Flash Software For Machines".
Find the ET directory by using the "File Manager". Open ET.
Start "WinFlash" by double clicking on the "WinFlash" icon with the pointer of the mouse. "WinFlash" is a part of the ET software package.
After the start-up is complete, ET will automatically try to connect to the GSC+ through the communication adapter.
The "WinFlash" program will display the serial numbers of any modules that are found on the data link.
Select the serial number of the unit that needs the software update. Click "OK". The serial number of the GSC+ that is desired can be obtained by looking at the first value under OP2-2 in Service Mode. In order to obtain the value, press the "Service Mode" key on the GSC+ once. Then, press the "SCROLL UP" key once. The "SCROLL UP" key is also the "LAMP TEST" key. All GSC+ units have a serial number suffix of "HA". This can be used for verification.
Insert the floppy disk or the CD-ROM that contains the flash file. Click on the "Select File" button and open the contents of the appropriate drive. Select the appropriate ".fls" file. If the flash file is already on the hard drive, select the file from the appropriate drive.
If the generator set has an energized-to-run solenoid, proceed to 9. If the generator has an energize-to-shutoff solenoid, wait for at least 70 seconds before proceeding to 9.
Click on the "Begin" button. The flash process should begin. A bar that shows the progress of the update will be displayed on the screen. Note: If power loss to the GSC+ occurs, the Flash Update procedure must be re-started from the first step.
The display of the GSC+ will be blank and the "Fault Shutdown" indicator will be blinking while the software update is in progress.
Do not disturb the process until the process is finished. Once the process is finished, the GSC+ will automatically start working again. Exit the "WinFlash" software.
The GSC+ should now have the new software. In order to verify the version of the software, go to the display at OP2-2. Scroll up one time. Read the part number that is displayed. Check setpoints P015, P016, and P026. Reprogram if necessary.
Turn the engine control switch (ECS) back to the "OFF/RESET" position and disconnect the negative terminal of the battery from the electrical system again. Disconnect the cables for the service tool. Remove the jumper wire from terminals 2 and 39 on the 40-contact connector if necessary. Close the panel.
Reconnect the battery to the electrical system and return the set back to service.
