Toro ECXTRA manual Automatic Circuit Protection, Adding a Zone Module

 Automatic Circuit Protection

The ECXTRA features built-in circuit protection to help prevent damage to the timer caused by excessive current draw on the zone and/or pump/master valve circuits. The instant an overload condition

is detected, the affected zone is turned OFF and the next zone in the watering sequence is turned

ON. The word “Fuse” and the bypassed zone number(s) will begin flashing.

If the condition occurs on the pump/master valve circuit, the timer will alternately display MV and FUSE and discontinue the program operation.

To clear the warning display, press the –/offbutton.

The timer will resume normal operation as scheduled and will attempt to run all zones as programmed.

IMPORTANT: Clearing the display does not correct the problem. The timer will continue to bypass the affected zones or discontinue operation until the overload condition is eliminated. Generally this con- dition is caused by a faulty valve solenoid or pump start relay. Before continuing to operate the timer, take corrective action to resolve the cause of the problem.

3.Place the back of the zone control module (model # 53741) squarely between the guides of the first open expansion slot (from left to right). Pushing lightly on the bottom of the module, slide it upward until it locks into position.

4.To connect the valve wires, refer to “Connecting the Valves” on page 7 or 11.

5.Install the lower front cover.

6.To set the zone run time, refer to “Setting Zone Run Times” on page 28.

7.To test the operation of the new watering zone(s),

refer to “Manual Operation” on page 31.
