Programming and Operation, continued

Note: If your system uses Rain Bird
®
Decoders and
Relay-100, change the Switch Code to 49F390.
Note: If your system’s water supply feeds directly
to a master valve, or if the system uses field
decoders or pressure switches to start pumps, you
may need to change the switch code. Please see
Appendix III: Master Valve and Pump Set-up Tips
on page 97.
4. Move the markers to the Address field and
select OK. The left and right arrow labels now
switch to up and down and the two markers
alternate blinking, indicating an active field.
5. Use the up and down arrows to enter the field
decoder Address marked on the irrigation
drawings.
6. OK accepts the Address and the markers stop
blinking. The up and down arrow labels also
change to right and left arrows. The next set
of options let you enter On and Off delays for
a MV/Booster activation or deactivation . The
On Delay means that the start will be delayed
XX seconds after decoder activation. The Off
Delay means the MV/Booster will remain
activated XX seconds after deactivation of the
decoder. This prevents the MV/Booster from
stopping between two steps. To enter additional
Booster pump Addresses, move the markers
to the OK field and select OK to return to the
Pumps screen.
7. Move the markers to Finish and select OK to
return to the Set-up Data Menu.
Note: To deactivate a pump/master valve for repair
or maintenance procedures, change the address to
zero (0).
Activating Rain or Alarm Sensors
The Rain Bird
®
MDC2 Controller has one sensor
input allowing you to install an optional rain or
alarm sensor. Once you install the sensor, you must
change the sensor status from Passive to Active.
Note: The MDC Controller supports only one Rain
Sensor or one Alarm Sensor. Activate only one
sensor leaving the other Passive. Setting both
sensors as Active actually changes the status of
both to Passive.
1. From the Main Menu, move the indicating
arrow to 1. Set-up Data and select OK.
2. Move the indicating arrow to 5. Sensors and
select OK to reach the Rain and Alarm Sensor
screen.
3. If your system uses a Rain Sensor, press the
buttons pointing to the arrow labels and
change sensor status from Passive to Active.
Note: If your system does not use a Rain Sensor,
keep the status Passive.
