Common Conditions

Your SMV motorized valve was thoroughly checked at numerous quality
control points during and after manufacturing and assembly operations.
It was carefully packed to prevent damage during shipment. Should you
feel that the instrument is not functioning properly please check for the fol-
lowing common conditions first:
=
Are all cables connected correctly?
=
Are there any leaks in the installation?
=
Is the power supply correctly selected according to requirements?
When several meters are used a power supply with appropriate cur
rent rating should be selected.
=
Were the connector pinouts matched properly? When interchanging
with other manufacturers' equipment, cables and connectors must
be carefully wired for correct pin configurations.
