COUNT INPUT SIGNALS

The instrument accepts count signals by:
Monodirectional encoders with NPN open collector or push-pull output
Bidirectional encoders with NPN open collector or push-pull output
1 Namur inductor with NPN open collector or push-pull output
2 Namur inductors with NPN open collector or push-pull output 90° degree out of phase

CONNECTION AND MAINTAINANCE

Link connections to the quick-coupling terminal box as mentioned in the enclosed diagram C2639.
To avoid damaging interference it is recommended, as for all low voltage equipment, to use a shielded cable for the
execution of connections and to separate the signal cable path of the counter from possible connection cables of power
utilities.
Counters do not require any particular maintenance. Keys shall not be pressed with sharp objects to avoid damaging of
the keyboard.
PRECAUTIONS
The visualiser is equipped with 2 command outputs which could get into an incoherent state in respect to the machine
working phase during the installing operations: it is recommended to put the machines in safety before starting the
configuring operations.

MANUAL STRUCTURE

Pages 1 to 3 of the present manual relate to the instrument
general working mode. Pages 4 to 6 relate to the operating way
of each operational mode.

INTRODUCTION
CM78N-C02 can be configured by the user to fit to different
operational modes.
The configuration is carried out in two phases:
Phase 1: Setting the basic operational mode
Phase 2: Setting the specific functions
In both phases the configuration is set by entering a numerical
code corresponding to the required operating options.
The available options are listed in the relevant tables at page 3 of
the present manual.
When the instrument is configured according to the requested
operational mode, it is necessary to enter its specific operating
parameters.

OPERATIONAL MODES DESCRIPTIONS
There are three basic operational modes available:
0) Position visualiser
1) Position visualiser with 2 settable thresholds
2) Absolute/relative position visualiser 2 settable thresholds
and 2 settable multiplying factors
A list of the main functions of the three different operational
modes follows:
OPERATIONAL MODE 0:
• Position visualisation
• Multiplying factor
• Count load
• mm/inch conversion
• Count/display block
OPERATIONAL MODE 1:
• Position visualisation
• Multiplying factor
• Count load
• mm/inch conversion
• Count/display block
• 2 alarm outputs
OPERATIONAL MODE 2:
• Absolute/relative position visualisation
• 2 multiplying factor which can be selected by input (the
number of decimals of the second factor can be set
separately)
• Count load
• Count/display block
• 2 alarm outputs
