User manual - COUNTER SLB-94
- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,
humidity, corrosive gasses and oils.
- Do not use the unit in areas where there is risk of explosions.
- Do not use the unit in areas with significant temperature variations, exposure to
condensation or ice.
- Do not use the unit in areas exposed to direct sunlight.
- Make sure that the ambient temperature (e.g. inside the control box) does not
exceed the recommended values. In such cases forced cooling of the unit must
be considered (e.g. by using a ventilator).
The unit is designed for operation in an industrial environment and must
not be used in a household environment or similar.

GENERAL CHARACTERISTICS
Universal totalizing counter
SLB-94
is designed for counting the pulses related to
physical quantities like
: number of revolutions, details, swichings etc. This counter allows to
counting in three internal registers called: main counter, cycles counter, and totalizer.
Particular counters are related to each other, what is described in this manual in details.
Settable recalculation factors (multiplier, divider and offset) allow displaying of the result
in desired units. It is possible to define four sets of recalculation coefficients mul-div-offset-
point (it means profiles), these profiles make recalculation between units easier. Main counter
range is limited from -99999 to 999999. Build-in totalizer is 12 digits long (-99999999999 to
999999999999).
The unit can control up to 4 external devices (motors, signalising devices) via build in relay
outputs, every in one of two modes (NO and NC). Activation of particular output can be done
after achieving of preset value (threshold) by the counter. Deactivation of the output can be
done after selected time (0 to 99.9 seconds or minutes) or when counted value goes less than
selected threshold related to particular output. The autoreset function allows zeroing of the
counter by itself when it reaches the threshold, and build in cycles counter counts the number
of autoresets or the number of R1 relay switchings. Manual zeroing of the counter causes
storing of present value into internal resets memory and makes possibility of its viewing in
future (maximum 5 last resets).
SLB-94
Is equipped in 3 inputs which allows external reset of selected counter. All
internal registers of the counter (including direct driving of relays) are available via RS-485
interface (with MODBUS RTU protocol). All inputs of the counter are separated.
