463X Chlorine Systems Manual
The troubleshooting table below outlines possible causes and remedies related to the fl ow cell panel system.
Refer to the respective transmitter and sensor manuals for specifi c component troubleshooting.
Problem Possible Cause Remedies
No water fl ow
Inlet pressure below 1 bar (15 psi)
Check source pressure. Remove regulator if pressure is
< 1 bar/15 psi
Damaged fl ow regulator Replace fl ow regulator
Clogged fi lter
Clean fi lter or remove pressure regulator if inlet pressure is
below 1 bar (15 psi)
Low water fl ow
Clogged fi lter Clean fi lter
Insuffi cient inlet pressure
Increase inlet pressure to specifi cation or remove fl ow
regulator
Damaged fl ow regulator Inspect or replace
Excessive fl ow
Excessive pressure over 8 bar (120 psi) Ensure inlet pressure does not exceed 8 bar (120 psi)
Damaged fl ow regulator Replace fl ow regulator
Flow cell leaks
Incorrect assembly Inspect, clean, and reassemble
Loose bolts Tighten bolts (8.1 Nm, 72 Lb-In Max)
Defective or missing O-rings Replace O-rings
Damaged sealing surfaces Replace fl ow cell
Leaks around sensor
Damaged sensor O-ring Inspect or replace O-ring
Damaged fl ow cell Inspect fl ow cell
Water leaks out of top vent hole
Drain valve closed or plugged Inspect
Hose connections are backwards Connect water source correctly
Outlet drain not below fl ow cell Route drain line below fl ow cell and vented to atmosphere
Algae growth in fl ow cell
Low chlorine concentration in water
Locate fl ow cell away from light
Exposure to light
Excessive small bubbles in fl ow
cell accumulating on sensors
Water source contains bubbles
Check water source
Water source is saturated with
dissolved gasses
Transmitter does not turn on
No power or external circuit breaker is
switched off
Inspect power and wiring connections
Loose or incorrect wire connections Check connections
Open loop wiring or missing jumper
wire on terminal 1 (Loop 1) on the
wiring enclosure terminal block
Replace jumper wire to terminal 1 or connect a loop device
if the jumper wire to terminal 1 is removed
Chlorine reading too high Breached membrane Replace membrane and fi ll solution
Chlorine reading too low
Electrode needs to be repolished Polish gold electrode
Not enough electrolyte Check electrolyte level
Low fl ow rate Check source pressure
Filter clogged Clean the fi lter
Sensor conditioning not long enough
Allow the sensor to condition for 4 hours
(See 2630 or 2632 sensor manual for details)
Sensor output drifts
Electrode needs to be repolished Polish gold electrode
Not enough electrolyte Check electrolyte level
Variable fl ow rate Check fl ow rate
Clogged fi lter Clean the fi lter
Contaminated fi ll solution Change electrolyte fi ll solution
