4-20 mA MODE
This parameter is selected independent of the Material Mode or Air Mode. Typically, when the display is
programmed for Material Mode, 20 mA will also represent a full tank. Inversely, when displaying in Air Mode, 20
mA will be set to represent an empty tank. However, both functions can be independently reversed if desired.
Note: If engineering units has been selected in the Units menu and a Cone Height greater than 0 has been
specified, the 4-20 mA output will be linearized for the cone section.
If power is in initial start-up or has been lost and restored, the 4-20 mA output will indicate greater than or equal
to a full tank. The actual output could be greater than or equal to 20 mA or less than or equal to 4 mA depending
on the selected mode. When a new reading is requested and the cycle is completed within the set tank
parameters, a new value (typically between 4 mA and 20 mA) will be produced. Once updated, the Yo-Yo sensor
will hold the 4-20 mA value until cycled again.
20 mA = Full (Default)
20 mA = Empty
AUTO-TIMER MODE
When the Auto-timer Mode is set to ON, the Yo-Yo sensor is able to take a reading automatically at an interval
defined in the Auto-timer Time menu. When the Auto-timer Mode is set to OFF, the Yo-Yo sensor will only begin a
measurement when manually requested. It is strongly recommended that the inhibit feature is utilized when using
the Auto-timer Mode.
ON
OFF (Default)

ENAbLE/DISAbLE SENSORS
All disabled sensors can be enabled or disabled from any active (enabled) sensor address. In a new system, the
readout will look for sensor address #01. Addressing is done via an 8-position DIP switch on each sensor. Other
sensors can be enabled from that address. Sensor enable/disable status is stored in EEPROM at the display.
Sensors to not have to sequentially addressed.
SAVE AND QUIT
This entry downloads all parameter additions or charges from the display to the selected sensor. All sensor
configuration information is stored in EEPROM on board each sensor. Enabled/disabled sensor information is
stored in the display.
