Step Thirteen
J. Programming SAFE Mode:
To change SAFE mode.
1. Press the SELECT/FAST button and hold it for 5 seconds until
PROG appears.
2. When SAFE appears, press the SELECT/FAST button.
3. The display will now rotate through 22mA, 21mA, 20mA, 4mA
and HOLD. When you reach the desired setting, press the
SELECT/FAST button to SAVE it..
You have successfully programmed the SAFE mode.
K. Programming Target Calibration (Optional):
The
transmitter’s 4 mA and 20 mA set points can be target calibrated ON
the tank by raising and lowering the liquid level, or OFF the tank
using the distance to a flat reflective target such as a wall. Generally,
target calibration is done ON the tank. To do so, follow the EMPTY
and FULL tank programming steps on the next page.
NOTE: A transmitter installed on a tank operating in the factory
default RUN mode will display the distance from the bottom of
the sensor to the liquid surface. The value will decrease as the
tank is filled or increase as the tank is emptied. Make sure that
you do not overflow the tank or completely empty the tank while
moving the liquid level to the desired high or low set point dis-
tance for target calibration.
TG CAL:
Allows the user to use an unknown distance for setting
of the 4 mA and 20 mA span.
FULL:
Target calibration technique that allows the user to enter
the present distance from the
transducer face to the liquid or a
reflective target as the 20 mA
(FULL) set point
EMPTY:
Target calibration
technique that allows the user to
enter the present distance from
the transducer face to the liquid
or a reflective target as the 4 mA
(EMPTY) set point.
Step Twelve
L. Programming TG CAL EMPTY Tank:
With the tank
EMPTY or the liquid in a low level state, apply power to the transmit-
ter. Begin programming after WARMUP.
1. Press the SELECT/FAST button and hold it for 5 seconds until
PROG appears.
2. When TG CAL appears, press the SELECT/FAST button. The
display will rotate between FULL and EMPTY.
3. When EMPTY appears, press the SELECT/FAST button. WAIT
will be displayed followed by SAVED.
You have successfully programmed the EMPTY or 4 mA value.
M. Programming TG CAL FULL Tank:
With the tank FULL,
or the liquid in a high level state, apply power to the transmitter.
Begin programming after WARMUP.
1. Press the SELECT/FAST button and hold it for 5 seconds until
PROG appears.
2. When TGCAL appears, press the SELECT/FAST button. The
display will rotate between FULL and EMPTY.
3. When FULL appears, press the SELECT/FAST button, WAIT will
be displayed followed by SAVED.
You have successfully programmed the FULL or 20 mA value.
