Checking operation

• The sensitivity of the photoelectric cursor is adjusted in the factory but we
recommend that you check the operation (as described in section 5) and adjust this
setting, if necessary, before you install the instrument.

• The instrument must be securely fixed to a wall or rigid bracket, independent of
pipework or vibration.

• It is important to use the correct density manometer liquid AWS 10 or VOLT 1S
depending on the model (consult us).

After fixing and levelling the ECM controller, unscrew the right hand connection
(viewed from the front) and slowly pour the manometer fluid, using the spout on the
Diagrama 2
bottle, up to the zero point on the scale.

Replace the connection. If necessary make fine adjustements to the zero point by

moving the graduated scale. Connect the manometer to the pressure or vacuum
source with clear tubing.

For a positive pressure (+), connect the tube to the left hand connection 0
of a vertical manometer, and to the right hand connection of an inclined
manometer. Make the opposite connections for vacuum.
For differential pressure measurement: connect the higher pressure (before
the filter) to the manometer (+) connection and the lower pressure to the
manometer (-) connection (after the filter).
