Rain Bird RASTER
TM
(Rapid Station Test Routine), continued
9
6. The display shows “TEST M1” and “TEST M2” as
the RASTER
TM
begins to check the operation of the
master valves (an automatic valve installed on the
mainline pipe upstream from the station valves).
7. If the display shows “SHORT M1” or “OPEN M1”
or “SHORT M2” or “OPEN M2” there may be a
faulty circuit between the controller and the
master valve. (On irrigation systems not equipped
with a master valve, the “OPEN M1” or “OPEN
M2” indicator is normal and requires no service.)
See “Troubleshooting Open and Shorted Valve
Circuits” on page 11 for more information.
