TroubleshooTInG.......................................................................
Problem
No Display
Display reads "Attention" (may
be followed by Sensor number)
Station does not irrigate
Controller does not irrigate
automatically
Rain or other Clik sensor does
not shut down system
Controller does not recognize
output module (station size
shown incorrect)
AC~ fuse blows
Multiple output module failures
83
Causes
Check AC~ power to controller
Facepack is not firmly seated and locked,
and/or 9-pin connector is not fully
connected
Gray ribbon cable is not connected from
back of inner panel to cabinet
ATTENTION indicates an alarm, an
active sensor, or trouble in the system.
ATTENTION means turn the dial to Data
History, select the Alarm Log, and find
detailed messages about each individual
alarm with date and time. A complete list of
alarm messages is included after this table
Field wiring or solenoid problem
Possible programming errors
Sensor shutdown
Programmable Off in effect
Time/Date errors
Incorrect sensor type or connection
Incorrect sensor settings for Program
Module seated incorrectly
Module slot skipped
Station output module overloaded
Incorrect AC wiring
Surge on AC power line
Lightning
Modules not installed correctly
Overcurrent message
Solutions
Fix power supply
Seat facepack in connector
Connect ribbon cable on back of facepack
door
Turn dial to Data History, select Alarm Logs,
and review for individual alarm events
The Controller Log and Station Log may
also be useful supporting information when
diagnosing problems
Perform Manual One- Station start and
observe display and output light
If light is red, check solenoid and field
wiring, including COM (common) wires.
Station outputs must not exceed 0.56A total
Verify all programs Days to Water, Start
Times, and Station Run Times
Check display for Fault indication (if yes,
press + for status)
Check display for Off days
Verify controller time and date, including
AM/PM/24 hour settings
Use one normally-closed Clik-type sensor
per sensor port (SEN1-4). Verify that one
wire from each sensor is to + and one to –.
Do not connect multiple sensors to a single
port
Turn dial to Set Sensor Operation and verify
correct response for each program to the
sensor ( Pause or Suspend)
Verify that modules are seated all the way up
in wiring compartment, and module lock is On
Verify that no module slots have been
skipped, from left to right
Re-seat module, and observe green station
light flashing when module is recognized.
No station light or red light
Swap with known-good module, check for
green light. If new module works, replace
old module (probably surge overload). If
new known-good module also fails to light,
check gold and silver contacts for dirt,
corrosion, pests.
Verify that AC connections are correct for
AC~ supply voltage
Check for lightning damage in vicinity
Check and improve earth ground
Insure that modules are inserted correctly
with ground contact in back, and pushed
all the way up- red light should light
momentarily when module is recognized
Too much current for station output (0.56
Amp max). Divide solenoids over more
station outputs
