2. GENERAL CHARACTERISTICS

LC-94 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.

This is a class A unit. In housing or a similar area it can cause radio

frequency interference. In such cases the user can be requested to use

appropriate preventive measures.

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 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:

- assembly brackets - 2 pieces,

- warranty,

- user’s manual for LC-94 unit (device)

4.2. ASSEMBLY

- The unit is designed for mounting inside housings (control panel, switchboard)

insuring appropriate protection against surges and interference. Metal housings

must be connected to ground in a way that complies with the governing

regulations.

- Disconnect the power supply prior to starting assembly.

- Check the connections are wired correctly prior to switching the unit on.

User manual for - TIMER SLC-94

In order to install the unit, a 90.5 x 4 mm mounting hole (Figure 4.1, 4.2) must be

prepared. The thickness of the material of which the panel is made must not exceed

5mm. When preparing the mounting hole take the grooves for catches located on

both sides of the housing into consideration (Figure 4.1, 4.2). Place the unit in the

mounting hole inserting it from the front side of the panel, and then fix it using the

brackets (Figure 4. ). The minimum distances between the centre points of multiple

units - due to the thermal and mechanical conditions of operation - are 115 mm x

67mm (Figure 4.4).

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.

User manual for - TIMER SLC-94

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

terminated with appropriate insulated cable tips.

- Tighten the clamping screws. The recommended tightening torque is 0.5 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 the unit must be applied. To avoid the 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-485 serial transmission connections.

-In the case of measurement or control signals are longer than 0m or go outside of the

building then additional safety circuits are required.

-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).

User manual for - TIMER SLC-94

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

connections on the back of the unit’s housing (Figure 4.5 - 4.6).
