7. TROUBLESHOOTING
Problem Possible cause Correcve acon
The controller
is not starng
aer powering
up the unit
No power /
incompable power
supply
Ensure that the power meets Technical specicaons.
If the power supply is adequate, then switch o the
power rst, open the controller housing and check:
— the fuses are not blown
— wires in screw terminals #30, #31, #32 are not loose
Circuit breaker
trips in the
main panel
Power supply does
not meet system
requirements
The system requires clean power supply compliant with
the Technical specicaons.
Check for brownout, overvoltage, power surges.
The pump will
not start aer
the controller
boots up
Controller is in
Standby mode
Check if the permeate tank is full, or if the oat switch has
stuck in the upward posion. Check that the permeate
pipeline is not blocked or shut o with a valve.
Controller is in Stop
mode
Push START buon to see if it is manually stopped. If
nothing happens, then (remove the power rst!) open
the electrical panel and check that Stop terminals are
connected with a jumper wire.
Controller is in Service
mode but the pump
isn’t running
Thermal protecon switch (built-in the motor juncon
box) may trip due to pump stalling, jamming, or
inadequate voltage. It will release aer cooling down.
Another possibility is a loose wire in the controller
terminal block or in the electrical panel (remove power
before accessing the electrical parts!)
Low feed
pressure
fault occurs
immediately
aer startup
The air has not been
completely purged
from the system
Fill the system completely with water. One way to do this
is to enter controller sengs and temporarily set 1.1 High
pressure pump delay to 255 seconds, then revert back
aer the air bubbles disappear.
Obstrucon in the
water supply pipeline
Avoid using long runs of small diameter pipes. Check that
there are no sharp bends if using a exible hose.
Clogged prelter Check the lter cartridge and replace if necessary.
Do not access any electrical parts before ensuring that the electrical power has been
removed.
Do not access any electrical parts or aempt any diagnoscs / repair unless you are a
trained electrician.
