Edwards nEXT 730D User Manual

When the BRIM process completes, the TMP runs to full speed and normal TMP process
can r
esume.
You can check the TMP inacve me (storage duraon) and reset BRIM status via:
▪ TIC – browsing to the „Service menu“, „Brg Inacve“ will display the TMP inacve
me. See TIC user manual for more details
▪ nST2 – See nST2 user manual for more details.
The purpose of recording the inacve bearing me is to maximize the life of the installed
ball bearing. If the bearings are inacve for a long me, the homogeneity of the grease
distribuon deteriorates, which leads to short-term local overheang of the grease in
the bearing when the pump is directly started up to nominal speed. This can lead to
decomposion or evaporaon of the grease. This grease is then no longer available for
the running me of the bearing and ulmately leads to earlier failure of the ball bearing.
The Bearing Run In Mode (BRIM), on the other hand, restores the homogeneity of the
grease distribuon by gently restarng the pump.
6.4 Bearing run in mode
Bearing run in mode (BRIM) is a start-up sequence for the pump designed to
precondion the bearing to opmise bearing life. The pump goes through a number of
speed steps before reaching full speed.
The BRIM process last around 4.3 hours and the LED indicates when this is running.
BRIM mode can be cancelled by sending a stop signal and then start signal to a pump
currently running the BRIM process. This is NOT recommended and may invalidate
the warranty.
BRIM mode is either triggered:
▪ automacally by the pump
▪ manually thr
ough nST2
▪ manually through the TIC, or
▪ by pressing both speed adjustment push buons (loca
ted behind the service
cover) simultaneously for 2s on the pump.
