(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.
