Installation and Maintenance Instructions for

N5500 Capsule Pressure Gauges

6.2 Installation

Devices with a blow-out require a minimum spacing to the rear

(1.0˝).

• Connection to be undertaken by authorized and qualified

personnel only

• Use only with the mechanical process connection provided

– regarding the configuration, see order code on the device

type label, with a matching threaded seal.

• When connecting the device, the pipes must be depressurized.

• The pressure metering pipe must be kept as short as possible

and laid without sharp bends, to avoid the occurrence of

delays.

• Devices with a blow-out require a minimum spacing to the

rear (1.0˝).

6.3 Start Up

The precondition for start-up is proper installation of all elec-

trical feed lines and metering pipes. All connecting lines must

be laid such that no mechanical forces can act on the device.

Before start-up, the seal on the pressurized connection line

must be checked

6.4 Zero point adjustment

The N5500 are supplied calibrated, so that as a rule there is no

need for calibration works at the installation point. Zero point

adjustment on site is standard. For this, proceed as follows:

Depressurize the pressure metering pipe.

• Open the bayonet ring and remove ring and window.

• Hold the pointer in place while turning the screw, until the

pointer (after releasing again) has the correct position.

• Close the case again and pay attention to correct fit of

window, gasket and bayonet ring.

• Liquid filled gauges must

be demounted before the

zero point adjustment can

be done (on a horizontal

area to prevent leaking).

7 SERVICING

The N5500 is maintenance-free. However, to ensure reliable

operation and a long lifetime, it is recommended that it is

checked regularly.

7.1 Safety

When undertaking servicing work on the N5500, the pressure

lines must be depressurized and the plant secured against being

switched on again.

7.2 In-service inspection

The check on function and recalibration is carried out at regular

intervals, depending on the application. The precise testing

cycles should be adjusted in line with the operating conditions

and ambient conditions. In the event of various device

components interacting, the operating instructions for all other

devices should also be taken into account.

• Check on display.

• Check on function, in conjunction with downstream

components

• Check of pressurized connection pipes for seal condition.

• Remove gauge from service should any leaks be identified.

7.3 Cleaning and maintenance

Cleaning is carried out using a non-aggressive cleaning agent,

with the ventilation valve closed and respecting the protection

category of the N5500.

8 APPENDIX

The N5500 is maintenance-free. However, to ensure reliable

operation and a long lifetime for the N5500, we recommend

that it is checked regularly.
