Preparation for Use
Unpacking
Check that the shipment is complete and that no damage has
occurred during transportation. If the contents are incomplete or
damaged, file a claim with the carrier immediately. Also notify
your local Pendulum sales or service organization in case repair
or replacement may be required.
Check List
The shipment should contain the following:
–
The counter, Model CNT-9X.
–
Line cord.
–
N-to-BNC Adapter (only for CNT-90/91 (R) Option 10 build
in).
–
Built-in options as ordered should be installed. See
Identification below.
–
Folder with Important Information.
–
Certificate of Calibration.
–
A CD-ROM including the following documentation in PDF:
•
Getting Started Manual,
•
User’s Manual,
•
Programmer’s Handbook.
Identification
The type plate on the rear panel shows the type number and the
serial number. See illustration on page 2-4. Installed options are
listed under the menu User Options - About, where you can also
find information on firmware version and calibration date. See
page 3-8.
Installed options can also be identified by checking the full type
number on the type plate.
Reading the Electronic Manuals
You need the Adobe
®
Reader
®
software to be able to read
the manuals on the CD. It is included on the CD or can be
downloaded free of charge from www.adobe.com
.
Insert the CD into the CD-ROM unit of your PC or Mac and
select the file you are looking for from the index.
Installation
Supply Voltage
Setting
The Counter can be connected to any AC supply with a
voltage rating of 90 to 265 VRMS , 45 to 440 Hz. The counter
automatically adjusts itself to the available line voltage.
Fuse
The secondary supply voltages are electronically protected
against overload or short circuit. The primary line voltage side is
protected by a fuse located in the power supply unit.
The fuse rating covers the full voltage range. Consequently there
is no need for the user to replace the fuse under any operating
conditions, nor is it accessible from the outside.
CAUTION: If this fuse is blown, it is likely that the power
supply is badly damaged. Do not replace the fuse. Send the
counter to the local Service Center.
Removing the cover for repair, maintenance and adjustment
must be done by qualified and trained personnel only, who are
fully aware of the hazards involved.
The warranty commitments are rendered void if unauthorized
access to the interior of the instrument has taken place
during the given warranty period.
Grounding
Grounding faults in the line voltage supply will make all
instruments connected to it potentially dangerous. Before
connecting any unit to the power line, you must make sure that
the protective ground functions correctly. Only then can a unit
be connected to the power line and only by using a three-wire
line cord. No other method of grounding is permitted. Extension
cords must always have a protective ground conductor.
CAUTION: If a unit is moved from a cold to a warm
environment, condensation may cause a shock hazard.
Ensure, therefore, that the grounding requirements are
strictly met. Allow enough time for the instrument to adapt
to new ambient conditions before connecting it to line
power.
WARNING: Never interrupt the grounding cord. Any
interruption of the protective ground connection inside or
outside the instrument or disconnection of the protective
ground terminal is likely to make the instrument dangerous.
