9.1.3 Configuration
Fig. 5: Configuration
The Configuration tab allows the level transmitter to be configured for the
specific application.
Factory Set:
Auto Threshold:
Default setting is ON and should not be turned off.
This feature allows the unit to automatically adjust the threshold for
optimal performance.
Product Float:
Default setting of ON for all applications.
Interface Float:
Default setting of ON if ordering 2 Loops. Default
setting of OFF if ordering 1 Loop. If the number of floats turned on is
different from the number of floats physically on the level transmitter
the level transmitter will go into Fault.
Serial Number:
Serial Number assigned by MTS at the time of manu-
facture. The serial number is used for tracking and replacement parts.
Do not change.
Temperature:
Default setting of OFF if ordered without temperature.
Default setting of ON if ordered with temperature. Turning tempera-
ture ON when the level transmitter was not ordered with temperature
will not cause temperature to work and will force the level transmitter
into Fault.
Display Enable:
Default setting of ON. Display can be turned off by
changing to OFF and cycling power.
User Configurable:
Reverse Measure:
Allows the end user to change the direction in
which the MTS level transmitter counts. The default setting is OFF and
the level transmitter will reference the tip of the pipe/hose and count
up from the tip. The ON setting will reference the head of the level
transmitter and count up as it moves towards the tip.
Device Address:
The end user can configure the Modbus address.
Default address is 247. The default address should not be used in a
network.
Baud Rate:
Allows the end user to select the desired baud rate. Default
setting is 4800.
Display Setting:
Allows the end user to configure the display. Available
options are level or volume. Default setting is level.
Volume Enable:
Allows the end user to turn ON and OFF the volume
calculation of the LP-Series.
9.1.4 Signal settings
Fig.6: Signal settings
Factory Set:
Gradient:
Is the speed at which the magnetostrictive signals travel
along the sensing element. Typical range is from 8.9 to 9.2. Do not
change unless replacing the sensing element. Changing this number
will directly affect accuracy.
Signal Gain:
Is the strength of the interrogation pulse. MTS uses the
same electronics for all lengths and adjusts the signal based on the
order length. Do not change unless instructed to do so by the MTS
Factory.
