F2–16TD2P, DC Output With Fault Protection, continued
When this module is installed, 16 X bits
are automatically assigned as fault status
indicators. Each X bit indicates the fault
status of a particular output.
Fault Status
Operation
Missing external 24VDC
Apply external 24VDC
Open load
Connect the load.
Over temperature
Turn the output (Y bit) off or
power cycle the PLC
Over load current
The fault status indicators (X bits) will
automatically reset once the fault condition is
corrected. Over temperature and over load can be
reset by turning the assigned output off or power
cycling the PLC.
In this example, X8-X23 are assigned as fault
status indicators.
X8: Fault status indicator for Y0
X9: Fault status indicator for Y1
X22: Fault status indicator for Y14
X23: Fault status indicator for Y15
This module detects the following fault statuses and
turns the related X bit(s) on.
1. Missing external 24VDC for the module
2. Open load
3. Over temperature (the output is shut down)
4. Over load current (the output is shut down)
Fault Status
X bit Fault Status Indication
Missing external 24VDC
All 16 X bits are on.
Open load
Only the X bit assigned to the
faulted output is on
Over temperature
Over load current
NOTE:
Open load detection can be disabled by removing
the jumper switch J6 on the module PC board. Disable if
the load might be energized by 200µA, or load resistance
is > 56k
