10. Troubleshooting for the
iDura (inverter range)
A comprehensive list of error messages and their causes
can be found in the Invertek OptiDrive E3 operation
manual.
Below are the typical troubleshooting error messages that may
be received based on Verder factory settings and relate to the
pump conguration:
1. “E-TriP” - the hose burst sensor has been triggered.
Check for a hose burst.
2. “l_t_trP” - suspected motor overtemperature. Allow motor
to cool and restart inverter.
10.1 Hose burst detection and vent
kit
Hose burst sensor supplied as standard with the iDura,
have been pre-wired to the inverter. No further wiring has
to be done by the user to use the hose burst detection.
Verderex hose burst detector and vent kit provide three basic
functions:
1. Stops the pump in conjunction with the inverter, in case of
accidental hose burst;
2. Detect over pressure inside the pump;
3. Release excess pressure from pump housing
The calibrated sensor detects any increase in the pressure
inside a pump casing. As the pressure threshold is reached,
the sensor changes state and this can be used to turn-o󰀨
the pump. The system has a detection threshold of 0.4 Bar
(5.8 P.S.I) and when the casing pressure exceeds this, it
initiate triggers the inverter to stop the pump. In the event of a
pressure rise inside the pump casing exceeding 2bar, the vent
kit helps to release this excess pressure from the pump.
