f)Press the red button ↵ to save this false echo and exit to the menu.

However, if this false echo shouldn't be saved, press the blue button → to exit to the menu.

g)To store another false target echo, re-start from step (b).

h)Press the green button ↓ to exit the menu and return to the PV display.

NOTE:

If there are two false echoes stored (“Lrn2”), the transmitter will not allow another echo to be stored until the memory is cleared (see next procedure.)

NOTE:

When a false echo is stored, the transmitter sets up a 'window' around the false target and ignores any echo from that window, unless the echo received from the liquid surface is larger than the stored false echo. There may be no change in the transmitter output current while the liquid level moves through this window, which is equivalent to a distance of 8 in. (20 cm).

NOTE:

See Figure 4-1 on page 4-3 for a map of the programming menu structure and how to access all the menu options.

To clear all the stored false echoes:

a)If entering the menu system from the PV display, press the green button ↓ repeatedly until the “Lrn” menu option is indicated (see above note.)

b)Press the blue button → to enter the “Lrn” menu.

c)With the display indicating “LrnX”, press and hold the green button ↓ for ten seconds to clear the memory. The display then indicates “Lrn0”.

d)Press the red button ↵ to exit to the menu.

e)Press the green button ↓ to exit the menu system and change to the PV display.

Final checks:

a)Check the display is reading correctly.

b)You may wish to check echo size again before re-fitting the enclosure lid.

c)Check that the cover seal is in place in the cover, and is good condition. It should not be twisted or kinked in any way.

d)Carefully set the cover on the transmitter, and tighten the three cover screws equally to seal the instrument.

e)Check that the cable gland is securely tightened and check sealing on the cable sheath.

All parameters are held in EPROM memory. In the event of a power failure, or disconnection from the power supply, the transmitter will remember all of it's last parameter values and will resume correct operation once power is restored.
