Siemens SIRIUS 3UG4 - Menu-Based Operation

3.6 Menu-based operation
Operator controls
The digitally adjustable monitoring relays have three keys for navigating on the menu levels:
• SET key
for navigating to the menu levels and for switching between the menu levels
• 2 arrow keys for setting parameters
Navigation through the menu system of the monitoring relays is explained below in a schematic
diagram.
Depending on the device version and as long as no faults have occurred, one or more di󹪜erent
measuring values ① can be displayed with the help of the arrow keys. In the event of a fault, the
display indicates the type of fault ③ by means of 󹪞ashing symbols. By repeatedly pressing the
SET key brie󹪞y, it is possible to set the desired type of monitoring (overshoot, undershoot, or
range monitoring) and parameterize the lower and/or upper threshold ② in accordance with
the device-speci󹪝c setting ranges. After pressing the SET key for at least 2.5 s, in a further step,
the basic device parameters ④, such as the switching behavior of the output relays, the reset
response in the event of a fault, and/or the tripping delay times can be set.
