1.2 Warranty

•Thewarrantytermsofthisinstrumentthatare

guaranteed are described in the quotation. We

will make any repairs that may become neces-

sary during the guaranteed term free of charge.

•Pleasecontactoursalesofficeifthisinstrument

requires repair.

•Iftheinstrumentisfaulty,contactuswithcom-

plete details about the problem and the length of

time it has been faulty, and state the model and

serial number. We would appreciate the inclu-

sion of drawings or additional information.

•Theresultsofourexaminationwilldetermine

whether the meter will be repaired free of charge

or on an at-cost basis.

The guarantee will not apply in the following

cases:

•Damageduetonegligenceorinsufficientmain-

tenance on the part of the customer.

•Problemsordamageresultingfromhandling,

operationorstoragethatviolatestheintended

use and specications.

•Problemsthatresultfromusingorperforming

1.3 Instruction according

EMC

The ROTAMASS Coriolis owmeter is conform

to the European EMC Guideline and fullls the

following standards:

EN61326-1:2006;

EN61326-2-3:2006;

EN61000-3-2:2006;

EN61000-3-3:1995+A1+A2

ROTAMASSisaclassAproductandshouldbe

used and installed properly according to the EMC

ClassArequirements.

RestrictiononUseofRadioTransceiver:

IMPORTANT

Althoughtheproductshasbeendesignedto 

resist high frequency electrical noise, if a radio

transceiverisusedneartheowmeterorits 

external wiring, the transmitter may be affected by

high frequency noise pickup. To test for such

effects,bringthetransceiverinuseslowlyfroma

distanceofseveralmetersfromtheowmeter, 

andobservethemeasurementloopfornoise 

effects.Thereafter,alwaysusethetransceiver 

outside the area affected by noise.

Installation

The function ground terminal or the PE-terminal

havetobeconnectedtoprotectivegroundto 

ensure electro-magnetic interference protection.

To ensure the EMC specications the following

measures must be carried out :

1. Put the power cables through the ferrite core

clamp before connecting to the terminals as shown

in chapter ´ Installation ´(Power supply wiring).

2. Put the I/O- cables through the ferrite core

clamp before connecting to the terminals as shown

in chapter ´ Installation ´(Power supply wiring).

3.Connectprotectivegroundconductorofpower

supply to PE-terminal in the terminal box (see

chapter ´ Installation ´(Power supply wiring).

4. In case of Explosion proof type instrument, fur-

ther requirements are described in chapter 9

“EXPLOSIONPROTECTEDTYPEINSTRUMENTS”.

The description in this chapter is prior to other de-

scriptions in this instruction manual.
