Automatic reset

All SIPROCESS GA700 devices feature internal monitoring. When this monitoring is
activated, the standard digital outputs switch after about 4 seconds for a period of approx. 60
seconds to "inactive", i.e. to a recognized safe operating mode. These times are valid for
devices manufactured as of 09/2017. You can find this information on the nameplate. It can
take up to 10 seconds for older devices to switch over, and up to 100 seconds to switch to
safe operating mode.
