[Emergency stop receive: Interlock disable]
When the emergency stop command is received from G(B)-50A, whether to enable or disable the
interlock operation depending on the change in input contact status can be set for each channel.
* The pressed (sunken) button shows the currently "Disable" status.
The interlock operation will be disabled for 15 minutes on the input channel on which "Disable" is
set after the emergency stop command is received from G(B)-50A.
Unless the emergency stop command is received again within 15 minutes, the "Interlock disable"
will be inactive after 15 minutes have passed.
For your safety, "Disable" is set (default) to all channels. However, the setting can be changed
on the unit that is required to be run at emergency. Consider carefully how the unit is required
to be run at emergency, and make the proper setting.
