Connection Diagram (1) Relay module on the GSC+ control. (2) AUX terminal strip. (3) 152-7143 GSC+ Data Cable . (4) Personal Computer. (5) 7X-1425 Data Link Cable. (6) 139-4166 Data Link Cable. (7) 7X-1701 Communication Adapter .Note: 24 VDC 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 7X-1425 Data Link Cable. The metal Deutsch connector should be connected to the "SERVICE TOOL" port on the communication adapter.
Connect the 139-4166 Data Link Cable to the "CONTROL" port on the communication adapter.
Connect 152-7143 GSC+ Data Cable to the opposite end of the 139-4166 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 Sockets. After the terminals have been replaced, the modified portion of the harness can be removed from the 40 pin connector by using the 121-9588 Wire Removal Tool .
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.Note: Power loss to the GSC+ is unacceptable once the process for the update of the software begins. The loss of power may render the GSC+ unusable.
Turn on the PC. The operating system on the computer must finish loading. Flash Update Procedure
