Dinel, s.r.o. PCU–100
GSM
Be extremely careful when placing the cover in place. It is not possible to set-
tle the front cover arbitrarily, there are located protrusions on the bottom of the
housing and on the body of the boxes. At bad settlement, these protrusions may
prevent the full engagement of the seal and the achievement of full coverage.
For more information on mechanical mounting, refer to the PCU-100 User's Guide.

A measuring probe is connected to the PCU-100 via a current loop (4-20 mA), which stores the
measured value according to the set period, which can be read based on the set current or using
the HART protocol (if the probe allows it). The PCU-100 with HART communication support is called
PCU-100 -_- H. More information on probe connection and proper setup can be found in the PCU-
100 User's Manual.
The measured value is stored in the internal memory and at the same time sent to the dinel.cloud
server together with the time stamp when the value was measured. The value is also shown on the
display if the PCU-100 has a display. The value sent to the server does not contain any information
about the unit (what physical quantity it is) and the user must know the individual values in advance
based on the set ranges and conversions. This setting is described in detail in the PCU-100 User's
Manual.
When using the GSM module, it is also necessary to have the correct time set on the PCU-100. This
must be in UTC for the correct display of the measured value on the web interface of the dinel.cloud
