User manual for - TIMER SLC-94
- 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
is designed for precision time (period) measurements, e.g. duration of time
interval and mesurements of machine's operating time
. Signals from push-buttons or
contactors of control devices are connected to the terminals placed on back side of the
counter. Properly programmed counter allows to measure time period between { START } and
{ STOP } signals. Other configuration allows to measure the activity time of { START } signal
( line { STOP } is then unused). In addition the measure can be started, stopped and cleared
using local keyboard (on front of the device) or via RS-485 interface.
Apart from basic function of time counting, totalizer is also available. Both counters, main
timer and totalizer are triggered and stopped simultaneously. Time counting is realised in
range 0 ms to 99 999.9 hours (maximum possible value). The device ensures a wide range of
precision and presentation formats of timer and totalizer.
Build in two relay outputs allow use of this counter for control in many time depend processes.
Build in RS-485 interface allows full control and programming of the device.
