005 - Station Electrical Current Too Low

Figure 146: Warning 005-Current Low Limit

The measured current lower limit value of electrical current is

less than the established limits. The warning lists the station

number (5) which was on at the time of the lower limit violation,

the Master Valve and/or Pump, as well as the measured electrical

current in amps (0.00). The current reading is the total or sum of

all outputs which are on. Upon detection of this condition, the

controller automatically terminates irrigation on the station and

advances to the next station in the program. Condemned stations

will not irrigate again until the warning has been cleared.

Action:

Step 1 Check field wiring for:

a. Faulty solenoid (open coil)

b. No station connection at terminal output board

c. Improper field wire connections at valve solenoid

d. Poor common connection in field wiring

e. Improper station limits

Step 2 If station limits are suspected, manually turn each

station on and observe the measured amperage

(electrical current) in the display area I=X.XX.

(Refer to Multi-Station Diagnostics procedure.)

Step 3 Compare the amperage reading with the limit setting

to insure that adequate margin exists (typical: 50%

under nominal).
