Examples For Determining Proper Dip Switch Settings To Achieve Optimal Lubrication - Perma Star Control Time Operating Instructions Manual

7.3.1 Examples for determining proper dip switch settings to achieve optimal
lubrication
In the "normal mode" (per 100 operating hours)
Example 1:
A roller bearing is to be provided with 14 cm
operation: 14 cm
The discharge table in chapt. 7.3 on page 14 shows that 3 different settings are
possible for each LC unit size
Variation I:
2.78 cm 3 /100 h for a 60 cm
Variation II:
3
2.78 cm /100 h for a 120 cm
Variation III:
3
2.89 cm /100 h for a 250 cm
At this point, you can calculate the total discharge life of the LC unit (and the ex
change date). Proceed as following:
The roller bearing to be lubricated is installed in a machine which runs 5 days per
week 8 hours per working day.
To Variation I:
The lubricant is sufficent for more than 1 year, not including additional operational
breaks or any other machine standstills.
