Repairs And Returns - KEP MMI-1500 Installation & Operation Manual

4.5 Repairs and Returns

An MMI is designed to provide years of trouble free service. An MMI under goes a full functional test before
shipment.
The MMI warranty is for one year under normal use.
The MMI does not require any "Routine Maintenance" by the user. If a problem should occur, and all troubleshooting
procedures have been exhausted, contact your local representative or distributor.
Use our toll free number to contact KEP if persistent problems are encountered.
Telephone: 1-800-631-2165.
If the product must be returned for any reason, be sure to call KEP and get a Return Goods Authorization
(RGA) number first.
Units should be returned in their original packaging container, otherwise, any suitable rigid container can be
used as a substitute. Use appropriate packing material. Damage due to shipment is not covered by the
warranty. Be sure to include a description of the problem and contact details for our repair department.
All returns are evaluated for proper operation. During evaluation, customer projects are not retained in the
units. If you need your project retained, please indicate this in the documentation included with the unit.
Products passing normal QC tests are returned to the customer and an evaluation charge is incurred.
If the problem is verified and the unit is in warranty, KEP will repair or replace the unit.
5.0 Quick Startup Guide
5.1 Connections
Set up the HMI with PC and PLC as described below.
a) Connect PC [RS-232] port of the HMI to the PC. Since the PC [RS-232] and PLC [RS-485] share the same D-SUB
connector, we recommend using the HMI to PC cable provided (MT5_PC). This splits the port into two separate connectors
to ease the program and test process.
b) Connect either the PLC [RS-485] or PLC [RS-232] port of the HMI to the PLC using the proper cable. (Check the PLC
signal type and cable listing in the back of this manual to assure proper port connections.)
c) Connect DC 24V power to the power connector. See Section 2.2.1 for power connection specifications.
Note: Check that all Dip switches are set to the "OFF" position.
d) Apply power and, if necessary, calibrate contrast adjust to the best viewing performance. (Not applicable for MMI-1500T)
Set new V4.5 hardware versions in RDS mode where contrast can be adjusted electronically.
