NOTE:
This “
SEt 20
” menu option is in the programming menu.
See Figure C-2 on page C-3 for a map of the menu structure and how to
access the menu options.
To set the 20 mA level:
a) If entering the menu system from the PV display, press the green button
↓
repeatedly until the “
SEt 20
“menu option is indicated (see note above.)
b) Press the blue button
→
to display the PV at 20 mA.
c) If the value is correct, press the red button
↵
to exit to the menu.
(The “
SEt 4
” re-appears. To get to the next menu option, press
↓
.)
d) With the transmitter aimed at a target a distance away equivalent to the
20 mA level, press the blue button
→
to start the ranging. The display
alternately flashes “
20
” and the live measurement reading.
e) Press the blue button
→
to confirm the PV at 20 mA is to be changed to
the same value as the live measurement reading.
f) If the new PV at 20 mA value is correct, press the red button
↵
to save
and then the green button
↓
to exit the menu system and return to the PV
display.
g) If the new PV at 20 mA value is incorrect, press the blue button
→
to exit
to the menu. The menu option “
SEt 20
” re-appears; re-start at step (b) or
press
↓
to exit the menu system and change to the PV display.
Programming of the transmitter is now complete.
Check the main display to ensure the duty, units and PV are correct, and that
relays are on or off according to the set points programmed. The cover may
now be replaced (see “After Completing the Wiring“ on page 3-9).
FINAL CHECKS
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.
POWER FAILURE
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.
