6.2 Clearance check
Be
fore installaon check the pump clearance.
Use the end of a pen or a similar tool to carefully rotate the rotor. While the rotor is
turning listen out for any clashing between the rotang and stac parts. Ensure the rotor
turns freely. If the rotor does not turn freely, contact your supplier.
6.3 Bearing monitoring and condioning system
To ensure maximum reliability and bearing life nEXT pumps have an integrated system to
manage the bearing condion. The status is indicated by a blue LED on the pump.
The pumps have an integrated baery-backed real me clock that is constantly
monitoring pump storage me.
The TMP motor controller when powered uses its processor and when unpowered the
real me baery backed clock to monitor the TMP inacvity me. Inacvity me refers
to both when the TMP is unpowered and when the TMP is powered but at rest. When
inacvity me exceeds:
▪ the pr
e-dened period of 12 mon
ths, a bearing condioning is required and
"Bearing Run in Mode" (BRIM) will commence at the next pump start.
▪ the pre-dened period of 3 years, a bearing replacement is required. The customer
will be alerted by the major service due indicator on the STATUS LED (yellow) and
on the Bearing LED (blue). Once the bearing is replaced and the major service
reset, a bearing condioning will be required and will commence at the next pump
start.
