4.4.3.2 DELA TIME DELAY
●
The DELA function of the menu makes it possible to program the
time-out after a failure is indicated by the transmitter by sending a
22 mA output current and switching the relay 2 if it has been
connected to an alarm.
●
The delay time will be activated at any time if the transmitter cannot
find or measure the level. The delay time should be selected in
respect to the process conditions eg: a short alarm time for a fast
process control.
4.4.3.3 CHOOSING THE TYPE OF TANK
For a good operation, the transmitter must know in which type of tank it is used.
The following drawings indicate which type of tank has to be selected within the
FILTER menu to obtain the most precise measurements:
By default, configure the mode indicated by the drawings.
Nevertheless, if the transmitter indicates a level which is twice the actual
level or that the tank is empty, the type of tank set within the FILTER menu
does not suit to the application and thus the next type in the list must be
chosen.
If for instance the type „CLOSED“ had been chosen and the transmitter
has this defect, set the type „DOME“.
«CLOSED» «OPEN TAN»
Flat roof
Rod
Plate
«DOME» or «DOME+» «DOME»
