    Step 5 (continued from previous page) use the instructions provided to test any valves (or solenoids or wires) on the stations with faulty resistance measurements (page 10 of this guide). A rain bird tone and probe kit (model ti-tpk) or a rain bird wire sorter (model ti-ws6) can be helpful in locati...

  • Page 5: Voltage Check Of 120V Input

    Voltage check of 120v input for standard outlets: 1) insert probes into outlet one at a time. 2) observe voltage reading on ti-dm200 display. 3) remove probes from outlet for hard wired controllers: 1) turn power off at main circuit breaker. 2) disconnect the wire nuts inside of the controller where...

    Resistance check of each station caution: turn controller off remove cover of controller to expose terminal strip. 1) touch (insert) one probe to the terminal labeled com (for common). 2) touch the other probe to the terminal of the station (or mv) to be checked. 3) check the reading on your multime...

  • Page 11: Voltage Check of Each Valve

    Voltage check of each valve 1) at the controller, turn on the station of the valve to be tested. 2) touch each probe to an exposed part of each of the two splice wires leading into the solenoid. If it is easier, disconnect the solenoid and just check the voltage drop across the two wires coming from...

  • Page 12: Voltage Check of Pump Relay

    Voltage check of pump relay 1) at the controller, turn on the station or master valve (mv) that controls the pump relay to be tested. 2) at the pump relay, expose a part of each of the two wires coming out of the relay. 3) touch a probe to each of the exposed wires. 4) check the reading on your mult...
