‣

Hazardous area

To eliminate a danger for persons or for the facility when the device is used in the hazardous
area (e.g. explosion protection, pressure vessel safety):

Based on the nameplate, check whether the ordered device is permitted for the intended

‣

use in the hazardous area.
Observe the specifications in the separate supplementary documentation that is an integral

‣

part of these Instructions.

5.1 Requirements

5.1.1 Alignment of NMS8x

Flange

Confirm that the size of the nozzle and the flange is matched prior to mounting NMS8x on
the tank. The flange size and the rating of NMS8x vary depending on the customer’s
specifications.

• Check the flange size of NMS8x.

• Mount the flange on the top of the tank. The deviation of the flange from the

horizontal plane should not exceed +/- 1 degree.

• When mounting NMS8x on a long nozzle, make sure that the displacer does not touch

the inner wall of the nozzle.

A0026889

 2 Allowable inclination of mounting flange

1 Nozzle

When NMS8x is installed without a guide system, follow the recommendations below:

• Confirm the mounting nozzle is in the sector between 45 and 90 degrees (or -45 and

-90 degrees)away from the inlet pipe of the tank. This prevents heavy swinging of the
displacer caused by waves or turbulence from the inlet liquid.

• Confirm the mounting nozzle is 500 mm (19.69 in) or more away from the tank wall.

• Confirm the minimum measuring level is at 500 mm (19.69 in) or more above the top

of the inlet pipe by setting the low stop (for details of low stop setting, refer to
"Commissioning" in the separate BA (Instruction Manual)). This protects the displacer
from direct flow of the inlet liquid.

• If a stilling well cannot be mounted in the tank due to the shape or condition of the

tank, attaching a guide system is recommended. Consult E+H services for further
information.

• Before pouring liquid into the tank, confirm that liquid flowing through the inlet of the

A0026890

pipe will not contact the displacer directly.

• When discharging liquid out of the tank, ensure that the displacer will not get caught
in the liquid current and sucked into the outlet pipe.

Proservo NMS83 Installation

5.1.2 Electrostatic charge

When liquid measured by NMS8x has a conductivity of 1 uS/m or less, it is quasi­nonconductive. In this case, using a stilling well or guide wire is recommended. This releases
the electrostatic charge on the liquid surface.

5.2 Mounting of the device

When NMS8x is delivered, the displacer is always shipped separately and there are two
methods to install displacer as follows.

• Installation for displacer shipped separately method

• Installation through the calibration window

5.2.1 Available installations

seals if necessary.

2. Tighten all housing screws and screw covers.

3. Firmly tighten the cable glands.

4. To ensure that moisture does not enter the cable entry, route the cable so that it loops
down before the cable entry ("water trap").

Sensor calibration adjusts the weight measurement of the detector unit. The calibration
consists of three steps as follows.

• ADC zero calibration

• ADC offset calibration

• ADC span calibration
For the ADC offset weight calibration, either 0 g or an offset weight (0 to 100 g) can be used.

Using an offset weight other than 0 g is recommended for density measurement.

Parameter Meaning / Action

Operating mode Select the operating mode (see diagram below).

Contact type Determines how the state of the external switch is mapped to the internal states of the DIO module

54 Endress+Hauser

• Input passive
The DIO module measures the voltage provided by an external source. Depending on the status
of the external switch, this voltage is 0 (switch open) or exceeds a certain limit voltage (switch
closed). These two states represent the digital signal.

• Input active
The DIO module provides a voltage and uses it to detect whether the external switch is open or
closed.

(see table below). The internal state of the Digital Input can then be transferred to a Digital Output
or can be used to control the measurement.

Parameter Meaning / Action

Alarm mode • Off

Alarm value source Select process variable to be checked for limit violation.

• HH alarm value

• H alarm value

• L alarm value

• LL alarm value

No alarms are generated.

• On
An alarm disappears if the alarm condition is no longer present (taking into consideration the
hysteresis).

• Latching
All alarms remain active until the user selects Clear alarm = Yes.

Assign appropriate limit values (see diagram above).

A0032464

 29 Possible locations of the Analog I/O modules, which can be used as an analog output. The order

code of the device determines which of these modules is actually present.

Each Analog I/O module of the device can be configured as 4...20mA analog output. To do so,
assign appropriate values to the following parameters:

Setup → Advanced setup → Input/output → Analog I/O

Parameter Meaning / Action

Operating mode Select 4..20mA output or HART slave +4..20mA output

Analog input source Select which tank variable is transmitted via the analog output.

Analog input 0% value Specify which value of the tank variable corresponds to an output current of 4 mA.

Analog input 100% value Specify which value of the tank variable corresponds to an output current of 20 mA.

1) "HART slave +4..20mA output " means that the Analog I/O module serves as a HART slave which cyclically sends
up to four HART variables to a HART master. For the configuration of the HART output:
