Normal Operating Status
In this status, the G9SP-series Controller is executing programming and oper-
ating normally. Operating status is divided into the following two states. For
details, refer to 9-3 Configuration Lock and Automatic Operation.
Stopped But No Error Detected
The G9SP-series Controller is not executing programming and operation is
stopped. However, no particular error has been detected in this status, and so
observe the following points to perform operation.
Status Action
Normal operating
status after complet-
ing user testing
User testing has been completed, and normal operation is
being performed in automatic operating mode. No particular
measures are required.
Normal operating
status during user
testing
User testing has not been completed, and so operation is
being performed with the configuration unlocked. The present
operation is normal, but the system will start in IDLE Mode at
the next startup. Change the operating mode from the G9SP
Configurator at every startup until user testing has been com-
pleted.
Operating status is
normal, but the
Safety Output does
not turn ON.
The following causes are possible. If none of the actions cor-
rects the problem, the Unit may be faulty. In that case, replace
the Unit.
1. Check to see if the output tag is ON.
Use the program monitor to see if the output tag is displayed
in green, indicating that it is ON.
2. Check to see if the Safety Output terminal is set.
Open the Safety I/O terminal settings to check the setting.
3. Either 24 V is not being applied to other Safety Output ter-
minals or Standard Output terminals or the power supply
positive terminal is not connected.
If this occurs, the output power supply OFF test will fail, so
the Safety Output will not turn ON for safety reasons. Check
the wiring and cycle the output power supply.
Status Action
Internal power not
supplied
Check the following before supplying the rated power.
• Is the power supply voltage within the specifications?
• Is the wiring correct or connected properly?
The Unit may have failed if the measured voltage at terminal
V1/G1 is normal. In that case, replace the Unit.
Stopped in IDLE
Mode
1. Change the operating mode using the G9SP Configurator
(9-2 Changing the Operating Mode).
2. Refer to 9-3 Configuration Lock and Automatic Operation if
the system starts in IDLE Mode when it was previously op-
erated in RUN Mode.
3. The mode will change from RUN Mode to IDLE Mode when
the Force Mode times out. Take suitable measures, such as
starting Force Mode again.
