Scenario 8 - DXi submaster 001-00 begins an automatic irrigation operation of
program 9 by activating MV1, Pump1 then station 1. Next DX2 satellite 001-02 begins
an automatic irrigation operation of program 5 by activating station 4. After station 4 is
activated by DX2 satellite 001-02 the measured current is below the minimum allowed
current.

Result 8 - DX2 satellite 001-02 deactivates S4, raises alarm 1005 "I Low Limit", and
condemns S4.
DX2 satellite 001-02 resumes automatic irrigation operation of program 5, for none
condemned stations. Manual or automatic operations will not activate S4 until alarm is
cleared
Note, Irrigation at submaster 001-00 is not affected in this scenario.
Scenario 9 - DXi submaster 001-00 begins an automatic irrigation operation of
program 8 by activating station 1. Next DX2 satellite 001-02 begins an automatic
irrigation operation of program 6 by activating MV1, Pump1 then station 4. After
station 4 is activated by DX2 satellite 001-02 the measured current is above the
maximum allowed current.

Result 9 - DX2 satellite 001-02 deactivates S4, raises alarm 1004 "I High Limit", and
condemns S4.
DX2 satellite 001-02 resumes automatic irrigation operation of program 6, for none
condemned stations. Manual or automatic operations will not activate S4 until alarm is
cleared
Note, Irrigation at submaster 001-00 is not affected in this scenario.
Note, DX2 controllers can't run diagnostic or condemn Master Valves or Pumps.
