Setting The Date And Time - Siemens SIRIUS 3RW55 Equipment Manual

Functions

8.17 Setting the date and time

Parameters
Permissible main power rotation
Response to faulty main power
Typical ambient temperature
(can only be set via 3RW5 HMI High Fea‐
ture)
1) In the 3RW5 HMI High Feature, the parameter is only visible if "Switch substitute value" is selected in the parameter "Response
to CPU / Master Stop".
This function is not available for the 3RW55 Failsafe soft starter.
2)
3) For 3RW55 soft starter from firmware version V2.0
8.17 Setting the date and time
Operating principle
The 3RW55 and 3RW55 Failsafe soft starters have a capacitor-buffered real-time clock with a
power reserve of about 3 days. You can set parameters for the date and time in the 3RW55 and
3RW55 Failsafe soft starters.
If the 3RW5 PROFINET High Feature communication module is used, time synchronization
according to the NTP method is available. You will find further information in the manual of the
3RW5 PROFINET communication module.

Description
• Any (factory setting)
The main power rotation may be "clockwise" or "counter-clockwise".
• Clockwise
The main power rotation must be "CW".
• Counter-clockw.
The main power rotation must be "CCW".
In certain applications, operation of the motor is permitted only in a specified,
preset direction of rotation, to avoid damage. The 3RW55 or 3RW55 Failsafe soft
starter detects the main power rotation via the measurement process. The re‐
quired main power rotation is determined when the application is first commis‐
sioned. Via the "Response to faulty main power" parameter, you can determine the
response of the 3RW55 or 3RW55 Failsafe soft starter to main power rotation
deviations.
• Group error only at ON command (factory setting)
If the 3RW55 or 3RW55 Failsafe soft starter detects a wrong main power ro‐
tation, a fault is generated.
• Warn
If the 3RW55 or 3RW55 Failsafe soft starter detects a wrong main power di‐
rection, a warning is generated.
The 3RW55 or 3RW55 Failsafe soft starter is set to the predominant typical ambi‐
ent temperature actually present in the system. Ensure that the set typical ambi‐
ent temperature is not exceeded.
• 40 °C
• 50 °C
• 60 °C (factory setting)
