configuration can cause defective operation, which can lead to unit damage or

an accident.

- If in t e case of a defect of unit operation t ere is a risk of a serious t reat

to t e safety of people or property additional, independent systems and

solutions to prevent suc a t reat must be used.

- T e unit uses dangerous voltage t at can cause a let al accident. T e unit

must be switc ed off and disconnected from t e power supply prior to

starting installation of troubles ooting (in t e case of malfunction).

- Neighbouring and mating equipment must meet the requirements of appropriate

standards and regulations concerning safety and be equipped with adequate

anti-overvoltage and anti-interference filters.

- Do not attempt to disassemble, repair or modify t e unit yourself. T e unit

as no user serviceable parts. Units, in w ic a defect was stated must be

disconnected and submitted for repairs at an aut orized service centre.

- In order to minimize fire or electric shock hazard, the unit must be protected

against atmospheric precipitation and excessive humidity.

- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,

humidity, corrosive gasses and oils.

- Do not use the unit in explosion hazard areas.

- Do not use the unit in areas with significant temperature variations, exposed to

condensation or icing.

- 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).

2. GENERAL CHARACTERISTICS

Time counter type SLC-457 is designed for time counting in range from 0 to 100 hours

with resolution of 1 minute. Actual result is showed on 4-digit display, and the user can change

it's bright in 8 steps range. The device is equipped with 4 buttons for main presets

programming. To get high protection level, the keyboard is mounted under transparent

waterproof cover. This feature allows to use SLC-457 in hazardous environments.

To allow user to change presets without opening of cover, an IR sensor is mounted.

Remote controller keyboard is equivalent to the device keyboard (Note, that remote controller

is not a part of the SLC-457 set. It is an option.).

Build in RS-48 communication interface enables remote access to all internal registers.

Baud rate can be changed from 1200 to 11 200 baud. SLC-457 has additional sensor supply

output, non separated, stabilized 24V DC ± %/ max. 100 mA.

4. DEVICE INSTALLATION

The unit has been designed and manufactured in a way assuring a high level of user

safety and resistance to interference occurring in a typical industrial environment. In order to

take full advantage of these characteristics installation of the unit must be conducted correctly

and according to the local regulations.

- Read the basic safety requirements on page 3 prior to starting the installation.

- Ensure that the power supply network voltage corresponds to the nominal

voltage stated on the unit’s identification label.

- The load must correspond to the requirements listed in the technical data.

- All installation works must be conducted with a disconnected power supply.

- Protecting the power supply clamps against unauthorized persons must be

taken into consideration.

4.1. UNPACKING

After removing the unit from the protective packaging, check for transportation damage.

Any transportation damage must be immediately reported to the carrier. Also, write down the

unit serial number on the housing and report the damage to the manufacturer.

Attached with the unit please find:

- warranty,

- user’s manual for SLC-457 unit (device)

4.2. CONNECTION METHOD

Caution

- Installation should be conducted by qualified personnel . During installation all

available safety requirements should be considered. The fitter is responsible for

executing the installation according to this manual, local safety and EMC

regulations.

- The unit is not equipped with an internal fuse or power supply circuit breaker.

Because of this an external time-delay cut-out fuse with minimal possible nominal

current value must be used (recommended bipolar, max. 2A) and a power supply

circuit-breaker located near the unit. In the case of using a monopolar fuse it must

be mounted on the phase cable (L).

- The power supply network cable diameter must be selected in such a way that in

the case of a short circuit of the cable from the side of the unit the cable shall be

protected against destruction with an electrical installation fuse.

- Wiring must meet appropriate standards and local regulations and laws.

- In order to secure against accidental short circuit the connection cables must be

terminated with appropriate insulated cable tips.

User manual for time counter SLC-457

- Tighten the clamping screws. The recommended tightening torque is 0. Nm.

Loose screws can cause fire or defective operation. Over tightening can lead to

damaging the connections inside the units and breaking the thread.

- In the case of the unit being fitted with separable clamps they should be inserted

into appropriate connectors in the unit, even if they are not used for any

connections.

- Unused clamps (marked as n.c.) must not be used for connecting any connecting

cables (e.g. as bridges), because this can cause damage to the equipment or

electric shock.

- If the unit is equipped with housing, covers and sealing packing, protecting

against water intrusion, pay special attention to their correct tightening or clamping.

In the case of any doubt consider using additional preventive measures (covers,

roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric

shock.

- After the installation is completed do not touch the unit’s connections when it is

switched on, because it carries the risk of electrical shock.

Due to possible significant interference in industrial installations appropriate measures

assuring correct operation of t e unit must be applied. To avoid t e unit of improper

indications keep recommendations listed below.

-Avoid common (parallel) leading of signal cables and transmission cables together with

power supply cables and cables controlling induction loads (e.g. contactors). Such cables

should cross at a right angle.

-Contactor coils and induction loads should be equipped with anti-interference protection

systems, e.g. RC-type.

-Use of screened signal cables is recommended. Signal cable screens should be

connected to the earthing only at one of the ends of the screened cable.

-In the case of magnetically induced interference the use of twisted couples of signal

cables (so-called “spirals”) is recommended. The spiral (best if shielded) must be used

with RS-48 serial transmission connections.

-In the case of interference from the power supply side the use of appropriate anti-

interference filters is recommended. Bear in mind that the connection between the filter

and the unit should be as short as possible and the metal housing of the filter must be

connected to the earthing with largest possible surface. The cables connected to the filter

output must not run in parallel with cables with interference (e.g. circuits controlling relays

or contactors).

Connections of power supply voltage and input signals are executed using the screw

connections on the back of the unit’s housing (Figure 4.1 - 4.3).

4.3. MAINTENANCE

The unit does not have any internal replaceable or adjustable components available to

the user. Pay attention to the ambient temperature in the room where the unit is operating.

Excessively high temperatures cause faster ageing of the internal components and shorten the

fault-free time of unit operation.

In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with

small amount of detergent or in the case of more significant contamination ethyl or isopropyl

alcohol.

Using any other agents can cause permanent damage to the housing.

6. PRINCIPLE OF OPERATION

After turning the power supply on, device ID and software version are showed on the

display, next the controller goes to the counting mode. After that unit goes to counting mode,

restoring counter value stored while power down.

6.1. TIME COUNTING MODE

In counting mode actual result is showed on the display. Result represents total time of

high level on {START} input (in „HH . MM” format). Low level on {START} input pauses

counting of time, without clearing of result. Next occur of high level on { START } causes

continuing of time counting (if result has not been cleared). Counting is signalised by blinking

decimal point between displayed hours and minutes. Decimal point lights continuously while

counting is paused.
