Eaton E5148C24 Serie Notice De Mise En Service

Operating Instructions
Electronic Preset Counter
E5148C24xx Series
1. Description
– 6 digit preset counter, 2 presets, add./subtr.
– bright 2-line LCD display with symbols for activated
outputs and current preset values
– count and preset range – 999999 to 999999, over- or
underflow without count loss up to 1 decade (will be
indicated by flashing of the display with 1 Hz
frequency)
– programmable to operate as a preset counter, timer or
frequency meter
– one or two preset values (selectable)
– relay or optocoupler outputs
– programming of count functions/operating parameters
via the setting keys. During programming the display
guides the user with text prompts.
– programmable features:
operating mode (output signal at zero or at preset
point, with or without automatic reset)
decimal point
polarity of the inputs (NPN or PNP)
input mode and scaling factor
output signals to be permanent or timed
gate time when programmed as a frequency meter
resolution when programmed as a timer (s, min, h or
h:min:s)
– supply voltage 230V AC, 115V AC, 48V AC, 24V AC or
11 – 30V DC
– backlit display
2. Inputs
2.1 INP A, INP B
Count inputs; max. count frequency 30 Hz or 10 kHz
separately selectable for both inputs via programming
switches C and D at the right side of the housing.

2.2 Gate
Static input; no counting while this input is activated. If
operated as a timer (only h, min and 0.1min resolutions),
the decimal point between the 5th and 6th decade
flashes while gate input is not activated (operating
indication).

2.3 Reset
Dynamic input; sets the counter to zero (adding mode)
or to preset value 2 (subtracting mode).
2.4 Key
Static keyboard lock input. While this input is activated, it
is neither possible to reset the counter nor to change the
preset values.

4. Outputs
4.1 Output 1
Relay with potential free make or break contact or
optocoupler with open collector and emitter.
4.2 Output 2
Relay with potential free change-over contact or
optocoupler with open collector and emitter.
4.3 Activated outputs
will be indicated by I and
For safety circuits the operation of the relay, or the
optocoupler may be inverted. Thus the relay coil will be
dead, or the optocoupler will be locked when reaching
the preset point / zero. For this application, the output
signals Out 1 and Out 2 must be set to – l – (permanent
signal) or – l – l – (timed signal) during the programming
routine.
Caution: For all operating modes with automatic
repetition (AddAr, SubAr, AddbAt, SubbAt) the duration
of the timed signal for output 2 has to be programmed,
otherwise the output signal has no defined duration (see
programming Out 2).
