Function Tests
For some safety gate applications, safeguarding devices require physical veri-
fication that the device continues to operate properly (e.g., required for Cate-
gory 2 safety gate applications).
If the function test is enabled for the Safety Gate Monitoring function block, a
safety gate test in which the safety gate must be opened and then closed
again can be added as a condition for turning ON the Output Enable signal.
If enabled, the safety gate test must be executed under the following condi-
tions.
1. Startup
The safety gate test must be executed when the NE1A-series Controller is
started (i.e., when the Controller’s operating mode changes from IDLE
Mode to RUN Mode). If the test ends normally, the Output Enable signal
will turn ON.
2. Function Test Request from the Machine
The safety gate test must be executed after the NE1A-series Controller de-
tects the Function Test Signal from the machine turn ON and before the
Function Test Signal turns ON again. If the Function Test Signal turns ON
a second time before the safety gate test is completed normally, a function
test error will occur, the Output Enable signal will turn OFF, and the Func-
tion Test Error signal will turn ON.
3. Error Detected in Safety Gate Monitoring Function Block
The safety gate test must be executed if a function test error, discrepancy
error, or other function block error occurs (after removing the cause of the
error).
The Function Test Required Signal from the Safety Gate Monitoring function
block will turn ON when a safety gate test is required and it will remain ON
until the safety gate test has been completed normally.
Set Parameters
The discrepancy time and synchronization time must be equal to or greater
than the NE1A-series Controller’s cycle time.
