Precipitation Sensor (15189 analog)
Dismounting of the protective covering
Loosening the screw (
fi
g. 1) with the provided 3 mm allen key
until the protective covering can be turned right to the stop
position and take off upward then.
Attention!
In order to protect the tipping bucket the
dirt spiral must be inserted in the collection funnel
(
fi
g. 2).
Assembly of the tipping bucket
To avoid damage to the tipping bucket during trans-
port, it is separately packed and should be inserted
in the precipitation sensor on site only after mounting
the gauge on the mast.
For the assembly
fi
rst you must remove the protec-
tive covering.
Attention!
When
fi
tting the tipping bucket, proceed
with utmost caution so that the sharp edges of the
tipping bucket are not damaged and the middle wall
is not bent!
During operation the tipping bucket lies on the precision buck-
et bearings. To reduce the friction, which is produced at one
tipping, the bearings are made of abrasion-resistant delrin.
The mounted tipping bucket is secured against eventual
changes of position by means of two plates.
To insert the tipping bucket,
fi
rst the relocatable locking plate
C
(
fi
g. 3) must be pushed back.
Now insert the tipping bucket

. Make sure that the magnet
E
attached at the middle wall of the tipping bucket rests under
the capsule with the embedded reed contact

.
Finally the tipping bucket must be secured by pushing back
the relocatable locking plate
