9.2.1.1 Power Input
Input voltage affects the whole unit, including the 48 Volts DC to the STVI from the PoE port,
and may or may not cause permanent damage if voltage is incorrect. These problems can often
be corrected by simply using a better source of input power. See unit front panel for input
voltage rating.
Some symptoms are as follows:
1. Low voltage: Erratic operation, no display, or a dim display.
2. High voltage: Circuit breaker operation on MVCT unit, power supply failure.
a. For MVCT, the internal power supply needs to be repaired or replaced, contact the
factory for further instructions.
9.2.1.2 Ethernet Cable
Basic troubleshooting of the Ethernet communication cable as follows,
1. No power: Check power source and line cord. If the MVCT powers up, but the STVI
display does light up, check the cable and cable connectors. Typical problem is usually a
broken conductor or cracked cable connector. Replace cable to see if this resolves issue.
2. Erratic Manual Control
A. Communication cable is not properly connected, thus cannot receive proper
commands.
B. Internal problem with communications inside the MVCT
Contact the factory for a Repair Authorization Number and return instructions if service is required.
A Repair Authorization (RA) number will be assigned for proper handling of the unit when it arrives at
the factory. Any non-warranty repair cost incurred for the repair or replacement of parts and/or
materials shall be the responsibility of the purchaser.
Provide the factory with model number, Unit serial number, nature of the problem or service required,
return address, your name, and how to contact you should the factory need to discuss the service
request.
You may need to provide a purchase order number, cost limit, billing, and return shipping instructions. If
an estimate is requested, provide the name and contact information.
