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.

If you are using SIPROCESS GA700 devices in critical processes, observe the following

information:

• Monitor the limits externally via the control system.

• If an option module 2.1 is installed, read out the device status via the digital outputs of the

option module.

• Use an available manual measuring range switchover instead of the autoranging.

• Only use the "Total" parameter with the "Off" setting for the measuring range switchover.

• If you use the "Correction of cross-interference" and "External pressure compensation"

functions, store suitable substitute values.

• Only access the measured value via an analog output.
