Test Output Mode Setting
The NE1A-SCPU01(-V1) is equipped with four test output terminals.
The NE1A-SCPU02 is equipped with eight test output terminals.
The following settings are supported for the test outputs.

Error Handling
Behavior on Error Detection
The following operations are performed if an error is detected during self-diag-
nosis:
•
The output terminals for which errors have been detected will be made
inactive without intervention from the user program.
•
The error will be recorded in the error history.
•
The NE1A-series Controller will continue to operate.
Error Latch Time Setting
The time to latch the error state when an error occurs in a safety input termi-
nal or test output terminal can be set. The error state will continue until the
error latch time passes even if the cause of the error is momentarily removed.
When monitoring errors from a monitoring system, take the monitoring inter-
val into account when setting the error latch time. The error latch time can be
set in increments of 10 ms between 0 and 65,530 ms. The default is 1,000 ms.
Resetting Errors
Errors detected at test output terminals will be automatically reset after the
error latch time. Leaving the short-circuit state as is may result in failure due to
increased temperatures. If an external load short circuit occurs, remove the
cause immediately.
Channel mode
Description
Not used
The corresponding test output terminal is not used.
Standard output
Connected to the input for indicator light or a PLC. Used as a monitor
output.
Pulse test output
Connected in combination with a safety input terminal and contact output
device. The test output terminal outputs a pulse for circuit diagnosis.
Pulses are output to each test output terminal at a different time.
Muting lamp output
Can be set as the output for a muting lamp. When the output is ON,
disconnection of the muting lamp can be detected.
With the NE1A-SCPU01, only the T3 terminal can be set to this mode.
With the NE1A-SCPU02, the T3 or T7 terminal can be set to this mode.
