Determination of the operating hours
The operating hours represent the time during which the supply voltage
is present at the device independent of the operating state.
The number of operating hours is indicated in the TopControl application
on the tab. See chapter 7.4.8.12, Seite 247.
8.1.1. Maintenance of the hardware
8.1.1.1. Fans
In principle the electronics in the TopCon TC.GSS power supply are
maintenance-free.
However, the following components require maintenance depending on
the number of operating hours:
Fans
Electrolytic capacitors.
The TopCon TC.GSS power supplies contain 3 temperature-regulated,
ball bearing mounted fans to cool the electrical and electronic components.
Life-expectancy – fans
Life-expectancy per fan with an average ambient
temperature of 40 ° C
