SE/SG-300 series two-wire compact ultrasonic level transmitters
5.
PROGRAMMING
The EchoTrek can be programmed by the following two ways:
•
Programming without Display Module
see 5.1.
Assignment of the levels to the 4 and 20 mA current output, error indication by the analogue signal and damping can be set.
•
With the
SAP-200 Display Module
, see 5.2.
All features of the unit can be set, such as measurement configuration and optimisation, 32-point linearisation, dimensions
for 11 tanks with different shape and for 21 different open channels (flume, weir, etc).
Devices with the type number
EchoTREK SG...
are already equipped with the SAP-200.
The EchoTREK is fully operational without the SAP-200. The SAP-200 is only needed for programming and/or displaying measurement values.
The unit will measure during programming in accordance with the previous parameters. The new, modified parameters will only be effective after
returning to the Measurement Mode
If the transmitter is left in Programming Mode by mistake, it will automatically return to Measurement Mode after 30 minutes and will operate with the parameters
entered during the last completed programming.
The EchoTREK will be delivered with the following
Factory Default
