3.12 Level Unit – Extra Sensor Data
The Extra Sensor Data-window shows the dynamic data and
the database values for the two extra temperature sensors
that can be connected to each transmitter.
Select a new tank by hitting the Tank-button or by hitting the
up or down arrow keys.
The dynamic data box shows:
• Sensor 4 and 5. The temperature measured by the
sensors are displayed in 1/10 of degrees.
The following status are shown:
• TX comfail indicates that the transmitter is not commu-
nicating. This produces an alarm on the alarm row.
• Sensor 4 or 5 fail. The temperature sensor has failed
when its box is checked. This status will also be shown
as an alarm.
The following database data are shown and can be changed:
• Sensor 4 and 5 type. This value shows if it is a three-
wire or four-wire type sensor that is used. The tempera-
ture range is also defined by this value. The following
values can be shown:
• 0. No connected temperature sensor.
• 1. Four-wire sensor. Temperature range 0 to +100°C.
• 2. Four-wire sensor. Temperature range -50 to +250°C.
• 5. Three-wire sensor. Temperature range 0 to +100°C.
• 6. Three-wire sensor. Temperature range -50 to
+250°C.
• Sensor 4 or 5 offset. An offset can be set for each sensor
individually.
Any changes of the database values must be followed by
hitting the Save-button as well as restarting the transmitter
by hitting the Restart TX-button.
