Important Notes
Usage for the intended purpose
Use the test station NRA 1-3 only in conjunction with the electrodes NRG 16-19, NRG 16-27 and
NRG 16-28 for monitoring steam traps for banking-up of condensate and loss of steam.
Safety note
The equipment must only be installed and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified personnel who – through
adequate training – have achieved a recognised level of competence.
Danger
The terminal strips of the test station NRA 1-3 are live during operation.
This presents the danger of electric shock.
Cut off power supply before mounting, removing or connecting the terminal strips.
ATEX (Atmosphère Explosible)
According to the European Directive 94/9/EC the equipment must not be used in explosion risk areas.
Explanatory Notes
Scope of supply
NRA 1-3
1 Test station NRA 1-3
1 Installation manual
Description
The measuring electrode detects banking-up of condensate and steam loss either directly in the steam
trap or in separate test chambers.
The measuring electrodes NRG 16-27, NRG 16-28 feature an additional temperature sensor for
measuring the temperature of the condensate.
Up to 16 measuring electrodes and a temperature sensor for measuring the temperature of the installa
tion can be connected to the test station NRA 1-3.
Function
The following electrodes can be used for monitoring steam traps:
n Measuring electrode NRG 16-19 for detecting banking-up of condensate or steam loss (electrode
submerged or exposed)
n Measuring electrode NRG 16-27, NRG 16-28 for detecting steam loss and banking-up of conden-
sate, with the condensate temperature being measured by an integrated temperature sensor
Three LEDs indicate banking-up of condensate, steam loss and malfunction in measuring electrode
(cable disruption, short circuit) and a three-digit seven-segment display shows the number of the
faulty steam trap. If more than one steam trap are defective the numbers of the faulty traps are
indicated one after another.
If banking-up of condensate, steam loss or malfunction in measuring electrode is indicated, an output
relay for the collective alarm will also be energised.
When using the measuring electrodes NRG 16-27, NRG 16-28 you can set the switchpoint for the
message “Banking-up of condensate” as a function of the separately detected temperature of the
installation or of the temperature measured in the steam trap.
The seven-segment display indicates every 6 months the maintenance interval of the measuring
electrodes in the form of an error code.
The seven-segment display indicates also status and error messages.

Test station NRA 1-3a
The enclosure of the test station NRA 1-3a is designed for wall mounting. The four fixing holes are
accessible after opening the base part. For this purpose use a screwdriver with a broad blade to lever
the hinge out of the slot on the left side, see Fig. 2.
Then use suitable screws and wall plugs to fix the rear cover.

Wiring
Connecting line of temperature sensor for detecting the temperature of the installation
Use screened three-core cable (e. g. Ölflex 110 CH, manufactured by LAPP, 3 x 0.5 mm²) for connecting
the sensor. Max. cable length between temperature sensor and test station NRA 1-3: 50 m. Connect
screen to the sensor.
Connecting line of measuring electrodes
NRG 16-19
The measuring electrode comes with a 2 m long connecting line and can be directly plugged into
the test station NRA 1-3. An extension is possible with screened two-core cable, e. g. Ölflex 110 CH,
manufactured by LAPP, 2 x 0.5 mm². Max. cable length between temperature sensor and test station
NRA 1-3: 50 m. Connect screen to the distribution substation.
NRG 16-27, NRG 16-28
Use screened five-core cable (e. g. Ölflex 110 CH, manufactured by LAPP, 5 x 0.5 mm²) for connecting
the electrode. Max. cable length between measuring electrode and test station NRA 1-3: 50 m.
Connect screen to the connecting coupler.
Wiring
NRA 1-3a
With the base part taken off:
1. Loosen the cable glands and pull the connecting lines through the glands.
2. Remove approx. 32 cm of the end insulation of the cable and the screen.
3. Connect the wires to the terminal strips (rear of base part) according to the wiring diagram and use
a cable tie for securing the cable bundle to prevent misalignment.
4. Tighten cable glands to achieve a good seal. Use sealing plugs to seal off cable glands that are not
used.
NRA 1-3e
1. Remove approx. 30 mm of the cable end insulation.
2. Connect the wires to the terminal strips (rear of base part) according to the wiring diagram.
Attention
n To protect the output relays provide the circuit with a T 2.5 A (slow blow) fuse.
n To suppress interferences provide connected contactors with RC combinations as
specified by the manufacturer.
n Install an easily accessible disconnector that serves as means of isolation from the
electrical supply near the test station (EN 61010-1).
n Label this disconnector as means of isolation for the test station.

With the parameter dtS the difference between the condensate temperature in the steam trap and the

The precondition for this operating mode is:

In the parameter mode CAL the condensate temperature from all steam traps is polled, the difference

Starting from the parameter mode ALL, the switchpoint “banking-up of condensate” can be adjusted in

Decommissioning
NRA 1-3
First disconnect the supply voltage and pull the cable out of the cable gland. Then disconnect the
measuring electrodes and pull the electrode cables out of the cable glands.
De-install the test station.
Danger
The terminal strips of the test station NRA 1-3 are live during operation.
This presents the danger of electric shock.
Always cut off power supply before mounting, removing or connecting the terminal
strips!
Disposal
NRA 1-3
De-install the test station NRA 1-3 and separate the waste materials, using the materials
specifications.
Dispose of electronic components (boards) separately.
For the disposal of the test station observe the pertinent legal regulations concerning waste disposal.
