004 - Station Electrical Current Too High

Figure 145: Warning 004-Current Upper Limit

The measured current upper limit value of electrical current is

greater than the established limits. The warning lists the station

number (17) which was on at the time of the upper limit

violation, the Master Valve (MV1) and/or PUMP, as well as the

measured electrical current in amps (.4). The current reading is

the total or sum of all outputs which are on, including any

Master Valve or Pump. 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 until the warning has been cleared.

Action:

Step 1 Check field wiring for:

a. Faulty solenoid

b. Field wiring which is exposed and submerged in

water

c. Station to earth ground and/or common

resistance path

d. 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. To

assist in the isolation of the faulty station, refer to

Multi-Station Diagnostics procedure.

Step 3 Compare the amperage reading with the limit setting

to insure that adequate margin exits (typical: 20%

over nominal).
