IRRIGATION ELECTRICAL SYSTEM FIELD TEST FLOW CHART STEP 1: DO YOU HAVE A CORRECTLY FUNCTIONING DISPLAY ON CONTROLLER WHEN YOU OPEN DOOR? YES: JUMP TO STEP 5 NO: CONTINUE TO STEP 2
STEP 2: SNIFF AND VISUAL TEST. DOES THE CONTROLLER HAVE A BURNT SMELL OR PHYSICAL SIGN OF DAMAGE? YES: SEND IN CONTROLLER FOR REPAIR. NO: PROCEDE TO STEP 3
STEP 3: DO YOU HAVE 24VAC ON SECONDARY SIDE OF TRANSFORMER? YES: CHECK TERMALS AND OTHER CONNECTIONS BETWEEN TRANSFORMER & CONTROLLER. IF ALL TESTS GOOD AND CONTROLLER STILL DOES NOT WORK, CHECK FUSE OR CIRCUITBREAKER. POWER DOWN THE CONTROLLER FOR ABOUT A MINUTE BY REMOVING 24VAC POWER, BACK UP BATTERY, AND THE COMMON WIRE(S). RECONNECT 24VAC, THEN COMMON THE BATTERY. IF YOU HAVE DISPLAY, COMPLETELY CHECKOUT CONTROLLER, IF NO DISPLAY SEND CONTROLLER IN FOR REPAIR. NO: CHECK FOR 120VAC ON PRIMARY SIDE OF TRANSFORMER CHECK PRIMARY SIDE AND SECONDARY SIDE FOR CONTINUITY, IF ONE SIDE IS OPEN, TRANSFORMER IS BAD. REPLACE TRANSFORMER AND START AT STEP 1 AGAIN.
STEP 4: CHECK FOR 120VAC AT CONNECTIONS ON PRIMARY SIDE OF TRANSFORMER YES: SHUT OFF 120VAC POWER SUPPLY TO CONTROLLER. DISCONNECT TRANSFORMER WIRES FROM 120VAC SUPPLY WIRES. DISCONNECT WIRES ON SECONDARY SIDE OF TRANSFORMER. CHECK FOR CONTINUITY THROUGH PRIMARY SIDE WIRES. CHECKCONTINUITY THROUGH SECONDARY WIRES. IF EITHER SIDE SHOWS “OPEN”, REPLACE TRANSFORMER THEN START AT STEP 1. NO: CHECK TO MAKE SURE SWITCH FOR POWER SUPPLY IS ON. IF IT IS AND YOU STILL DO NOT HAVE 120VAC AT CONNECTIONS TO TRANSFORMER, CALL YOU FAVORITE ELECTRICIAN. DO NOT WORK WITH 120VAC UNLESS YOU HAVE AN ELECTRICIANS LICENSE.
STEP 5: TEST THE OUTPUTS. DO ALL THE OUTPUTS TURN A SOLENOID ON AND OFF? YES: CHECK CONTROLLER SWITCHES, KEYPAD KEYS, AND FUNCTIONS. IF ALL FUNCTIONS WORK NORMALLY, CHECK PROGRAM, CLOSE DOOR AND GO TO NEXT JOB. NO: TEST NON WORKING ZONES' OUTPUT TERMINALS FOR 24V OUTPUT.
STEP 6: DO ALL TERMINALS HAVE 24VAC OUTPUT? YES: TEST ALL NONWORKING ZONES FIELD WIRING ACCORDING TO THE FIELD RESISTANCE TEST WORKSHEET. NO: SEND IN FOR REPAIR. IF CONTROLLER HAS UPPER AND LOWER BOARDS, SEND BOTH BOARDS IN TO BE REPAIRED.
STEP 7: DID ALL FIELD CIRCUITS TEST OK? YES: CHECK ALL CONTROLLER OUTPUT CONNECTIONS AND RETEST ACCORDING TO STEP 5. NO: DISCONNECT VALVE WIRES FROM BAD CIRCUITS AND COMMON WIRE(S) FROM CONTROLLER. FIND VALVES ON BAD CIRCUIT. DISCONNECT VALVE WIRES FROM FIELD WIRES. TEST OHMS VALUE OF VALVE SOLENOID.
STEP 8: DOES SOLENOID HAVE CORRECT OHMS RATING? YES: TEST FIELD WIRING FOR OHMS NO: REPLACE WITH CORRECT SOLENOID AND RETEST
STEP 9: DOES FIELD WIRING HAVE PROPER OHMS READING?(SHOULD READ “OPEN”) YES: RECONNECT ZONE VALVE WIRE AND COMMON WIRE TO THEIR CORRECT TERMINALS AT CONTROLLER. TURN ON ZONE FROM CONTROLLER. TEST FOR 24VAC AT FIELD WIRES NEAR VALVE. NO: YOU MAY HAVE A SHORT. FIND PROBLEM WITH FIELD WIRING, REPAIR AND RETEST ACCORDING TO FIELD TEST WORKSHEET.
STEP 10: IS THERE 24VAC ON FIELD WIRES AT ZONE VALVE? YES: RECONNECT VALVE SOLENOID WIRES TO FIELD WIRES. TURN ON ZONE AT CONTROLLER. NO: YOU MAY HAVE A BROKEN WIRE. FIND PROBLEM USING PROGRESSIVE ELECTRONICS OR SIMILAR EQUIPMENT, REPAIR AND RETEST FROM STEP 9.
STEP 11: DID ZONE VALVE TURN ON? YES: GO TO NEXT BAD CIRCUIT AND TEST ACCORDING TO STEP 7 NO: CHECK FOR 24VAC AT SOLENOID/FIELD WIRES CONNECTIONS
STEP 12: IS THERE 24VAC AT SOLENOID/FIELD WIRE CONNECTIONS YES: FEEL AND LISTEN FOR VIBRATION/HUM OF SOLENOID. IF NONE, CHECK FOR MECHANICAL OPERATION OF SOLENOID AND/OR VALVE ACCORDING TO THE MANUFACTURES RECCOMMENDATIONS. NO: YOU MAY HAVE A SHORT TO GROUND SITUATION. TEST WITH PROGRESSIVE ELECTRONICS OR SIMILAR EQUIPMENT, REPAIR, AND RETEST FROM STEP 11 © Control Tech USA, Inc 2005
