The wiper arm will move twice every 20 mins as a default setting, if the face of
the transducer is dirty and you are unsure as to whether or not the wiper is cleaning
then place the transducer such that the wiper movement will not foul on anything
and use the appropriate function key ( ) to force a wipe (see note below).
The function key will only initiate a wiper sweep on a VT transducer
related to the currently viewed point and will only operate in runmode on
the “Main” display. The function key will not initiate a wiper sweep if the
dual point view is displayed.
If it is necessary to replace the transducer, the following procedure should be
followed.
Disconnect the transducer wiring from the electronics as shown on page 15 and
remove the transducer cable from the electronics enclosure.
The transducer is mounted onto the end of the conduit via its process fitting, this
should be carefully unscrewed in an anticlockwise direction. Make sure the
transducer is not dropped or knocked as this can damage the unit.
When replacing the transducer care must be taken not to over tighten the unit as
this can result in the transducer ‘ringing’. Hand tight is sufficient.
When the transducer is replaced into the application and the power re-applied the
unit will re-initialise and after a short period of time depending on the process
conditions show the correct blanket reading.
