specified input levels.
MUX.x Ext Sync Loss MUX.x Ext Inp Sync Err TTX External Input Sync Loss
Occurs when configuring stack
and unit encounters momentary
loss of signal. If unit is functioning normally, clear faults and continue
operations.
If unit continues to log this as a current fault, reset unit.

Verify MCPC stack configuration. Ensure encoder MUX
rates are in sync.
MUX.x Loc Input MUX.x Loc Input Loss TTX Local Input Loss If current fault, reset unit. If unit continues to fail, contact
Tiernan Customer Service.
If in fault history log, clear faults and continue operations.
MUX.x Loc PAT MUX.x Loc PAT Timeout TTX Local PAT (program
association table) Timeout
Occurs on power-up. If unit is functioning normally, clear faults and continue
operations.
If unit continues to log this as a current fault, reset unit.
MUX.x Loc Sync MUX.x Loc Input Sync TTX Local Input Sync Loss
Occurs when configuring stack
and unit encounters momentary
loss of signal. If unit is functioning normally, clear faults and continue
operations.
If unit continues to log this as a current fault, reset unit.
