E042 TCU Temperature error • Check TCU to be sure it is not too
close to sources of heat. Relocate
TCU, if possible.
• Verify TCU has room around it for air
circulation. Move objects preventing
air flow.
• Contact technical staff.
If errors persist with proper location and
airflow and correct power is connected,
unit has suffered internal failure. Call
MRC Technical Support.
E043 TCU 75 Ohm Coax Current Error Note - these errors can only appear in a
TX System with TXU and a TCU, when
powering the TXU from the TCU or from
the TCU to the TXU via DC power
superimposed on the coax cable
between the TCU and the TXU.
• Check connection of coax cable
between TCU and TXU. Verify
connectors are fully mated and verify
cable and connectors are
undamaged.
• Make sure all power cables are
connected properly.
• Contact technical staff.
If errors persist with correct coax
connections and correct power
connected, unit has suffered internal
failure. Call MRC Technical Support.
E044 TCU 75 Ohm Coax Voltage Error
E045 TCU 75 Ohm Coax Power Error
E046 TCU Circular Connector Current
Error
• Make sure all power cables are
connected properly and are not
damaged.
• Verify correct DC input power is being
applied to the TCU.
• Contact technical staff.
If errors persist with correct power
connected, unit has suffered internal
failure. Call MRC Technical Support.
