Checking wiring
Before installation check the wiring:
n
Are the temperature sensors wired according to the wiring diagram?
n
Is the wiring of all CAN bus devices in accordance with the wiring diagrams?
n
Is the polarity of the bus line always correct?
n
Are all the end-of-line devices of the bus line provided with a 0 Ω terminating resistor?
Applying supply voltage
Switch on supply voltage. The two seven-segment indicators are tested, which means that all
segments and decimal points are flashing. The test is also carried out whenever the connector for the
bus line is pulled out of the transmitter and then plugged in again.
Changing system configuration
The control units NRS -40. and NRS -40. associated with the temperature transmitter TRV 5-40
are designed for four limiting functions for monitoring liquid level and temperature. The level electrodes
NRG x-40, NRG x-4. and the temperature transmitter TRV 5-40 are to be connected to the control
unit NRS -40.. The level electrode NRG x-4 and the temperature transmitter TRV 5-40 have to be
connected to the control unit -40..
For the operation of the limiting system it is necessary to establish in the control unit the number of
sensors with which the equipment has to work.
For more information see chapter “Commissioning” in the installation manual NRS -40. and
NRS -40..
The following settings can be adjusted with the TRV 5-40:
n
Communication with control unit NRS -40. or NRS -40.
n
Communication with the control unit operating as limiter , , 3 or 4
