System Display Fault Cause
(most likely to least)
Remedial Action
Very High Cell Current
Cell Amperage
exceeds max limit for
longer than 10 sec.
1. Low water flow
2. Water flow
control valve
failure
3. Brine
proportion
pump
malfunctioning
1. Check fuse for
water solenoid
2. Contact MIOX
Customer
Service
Low Cell Voltage
Cell voltage below
lower limit (30 VDC)
1. Breaker
tripped
2. Contactor
failed
3. Low AC voltage
feeding system
1. Reset large
breaker (CB1)
in switch gear
panel (Figure
33)
2. Contact MIOX
Customer
Service
3. Verify feed
voltage meets
specification
High Cell Current
Cell amperage exceeds
limit for longer than
10 sec
1. Low water flow
2. Water flow
control valve
failure
3. Brine
proportion
pump
malfunctioning
1. Verify water
flow is within
system
specifications
2. Check fuse F10
on control
interface board
(Figure 34)
3. Contact MIOX
Customer
Service
Low Water Pressure
Water pressure below
35 PSI
1. Low water
pressure
2. Water boost
pump failure
1. Verify water
pressure meets
system
specifications
2. Verify
operation of
water boost
pumps. Check
fuse F1 on
control
interface board

Diode Temperature
Temperature of diode
bar in transformer
compartment exceeds
max temperature
1. Insufficient air
flow to
transformer
2. Excessive
current draw
on diode bank
3. Temperature
switch failure
1. Verify cooling
fan operation
2. Verify
operation of
current sensors
3. Replace
temperature
switch
