39 463X Chlorine System Manual
The troubleshooting table below outlines possible causes and remedies related to the À ow cell panel system.
Refer to the respective transmitter and sensor manuals for speci¿ c component troubleshooting.
Problem Possible Cause Remedies
No water À ow
Inlet pressure below 1 bar (15 psi)
Check source pressure. Remove regulator if pressure is
< 1 bar/15 psi
Damaged À ow regulator Replace À ow regulator
Clogged ¿ lter
Clean ¿ lter or remove pressure regulator if inlet pressure is
below 1 bar (15 psi)
Low water À ow
Clogged ¿ lter Clean ¿ lter
Insuf¿ cient inlet pressure
Increase inlet pressure to speci¿ cation or remove À ow
regulator
Damaged À ow regulator Inspect or replace
Excessive À ow
Excessive pressure over 8 bar (120 psi) Ensure inlet pressure does not exceed 8 bar (120 psi)
Damaged À ow regulator Replace À 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 À ow cell
Leaks around sensor
Damaged sensor O-ring Inspect or replace O-ring
Damaged À ow cell Inspect À 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 À ow cell Route drain line below À ow cell and vented to atmosphere
Algae growth in À ow cell
Low chlorine concentration in water
Locate À ow cell away from light
Exposure to light
Excessive small bubbles in À 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 ¿ ll solution
Chlorine reading too low
Low À ow rate Check source pressure
Filter clogged Clean the ¿ 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
Variable À ow rate Check À ow rate
Clogged ¿ lter Clean the ¿ lter
Contaminated ¿ ll solution Change electrolyte ¿ ll solution
