Alarm
Type
Indication
Probable Cause
Corrective Action
[XX] Corrosion ([XX] = Probe metallurgy)
High
Mesurement
exceeds High
Alarm threshold
1) Insufficient flow rate past probe.
2) High Alarm threshold set too low.
3) Corrosion treatment program needs adjustment.
1) Verify minimum of 5 gpm flow is present.
2) Readjust alarm threshold.
3) Consult your Nalco Representative.
Cell Fouling
High
Mesurement
exceeds High
Alarm threshold
1) Fluorometer flow cell is fouled.
2) High Alarm threshold set too low.
1) Clean flow cell with supplied brush and cleani ng
solution. Recalibrate as needed.
2) Readjust alarm threshold.
Control Relays (TRASAR, Tagged Polymer, Bio-reporter, Oxidizing Biocide, Blowdown, pH)
Relay
Timeout
Relay has been
activated for
longer than relay
timeout limit
1) Tank empty/pump lost prime/faulty pump or valve.
2) Relay Timeout Limit set too low.
3) Feed/bleed rate too low for demand.
1) Check tank/pump/valve/feed line. Repair as
needed.
2) Readjust alarm threshold.
3) Increase feed/bleed rate.
General Sensors
Sensor
Error detected
with indicated
sensor probe.
1) Wiring or other connecti on is loose.
2) Sensor probe failure.
1) Retighten wires or other connections. Be sure wire
insulation is not preventing good contact.
2) Replace probe. Probe replacement may be
included in purchased service plan.
Sample
Flow
Low
Insufficient water
flow through
fluorometer cell
1) Flow rate too low or back pressure too high. Flow
switch requires 0.5 gpm.
2) Flow switch fouled.
3) Flow switch wiring is loose or not making good
connection.
1) Investigate and correct.
2) Clean flow switch.
3) Replace flow switch
Interlock
Absent
The interlock
input has been
deactivated
1) The interlocking device is not active.
2) Interlock is not used and jumper is not in place.
3) Interlock wiring is loose or not making good
connection.
1) Check. This may be expected operation.
2) Replace jumper (refer to wiring diagram for
location and di rections.
3) Check and correct wiring connections.
Fluor.
Comm.
Controller is
unable to
communicate
with the
fluorometer
1) Cable connector on Fluorometer is loose.
2) Wiring from fluorometer is loose or miswired in
controller.
3) Component failure.
1) Disconnect and inspect for bent pins or signs of
damage, then reconnect.
2) Check and correct if needed (see wiring diagram
for details).
3) Reboot system by momentarily cycling power to
initiate recovery. If unsuccessful contact Help D esk at
630-305-CHEM for assistance.
Sensor
Board
Comm.
The sensor
board is not
communicating
with the
controller
1) Sensor board is loose preventing good con nection.
2) Component failure.
1) Gently press on "Red" circuit board inside
controller to ensure snug fi t.
2) Reboot sytem by momentarily cycling power to
initiate recovery. If unsuccessful contact Help D esk at
630-305-CHEM for assistance.
3D Bio Control
Pellet
Feeder
Comm.
Controller is not
communicating
with Pellet
Feeder
1) Pellet Feeder cable loose or connections not made
correctly.
2) Pellet Feeder power switch is not turned on.
3) Component failure.
1) Disconnect and inspect both Pellet Feeder
connector and wi ring in controller, then reconnect.
2) Turn power switch on.
3) Reboot system by momentarily cycling power to
initiate recovery. If unsuccessful contact Help D esk at
630-305-CHEM for assistance.
Pellet
Feeder
Busy
The Pellet
Feeder has not
completed a
pellet feed
before the next
pellet is called
for
1) Pellet supply is low.
1) Check and fill Pellet Feeder, or redistribute
remaining pellets.
Pellet
Supply
Low
The Pellet
Feeder has not
fed a pellet
when called for
1) Pellet Feeder is empty.
1) Check and refill Pellet Feeder.
Pellet
Sensor
Error
The Pellet
Sensor LED is
blocked.
1) The clear pellet feed tube is blocked or dirty
preventing light transmission.
1) Check and clean feed tube usi ng supplied brush.
