General: The controller provides unrealistically large temperature jumps - Measured values are shown for a short time when sensor is not connected.

General: The controller provides unrealistically large temperature jumps - Measured values are shown for a short time when sensor is not connected.

- Is the shield for the sensor installed correctly?
- Is the CAN bus shield installed correctly?
Are faults coupled to the control component via the CAN bus?
- Is the PE ground conductor of the store connected correctly (store electrical installation)?
- Are there non-suppressed electronics in the control panel (only for control panel operation) (e.g. regulated drive, phase controller)?
- Is the control panel (control panel operation only) grounded properly?
- Can a low resistance between data cable / sensor cable be measured?
- Is there a short-circuit between sensor cable and refrigerated display case (sensor not installed correctly on case)?
Possible cause:
1. External faults on the control component
2. Control component defective, contact manufacturer.

Erklärung:

Jeder User des EDP hat einen zusätzlichen Cloud-Speicher. Innerhalb der OwnCloud können Pfade erstellt werden, die hierüber mit einer EDP-Komponente verknüpft werden.

Auf diese Weise sind z.B. Massen-Uploads ins EDP möglich, d.h. es können beliebig viele Dokumente in den Pfad der OwnCloud kopiert werden, die dann automatisch in die zugeordnete Komponente im EDP synchronisiert werden.
