2. GENERAL CHARACTERISTICS

The SLN-44 is a DIN 48 x 48 mm electronic preset counter with a Blue TN LCD display

with white backlight. The display is 6 digits dual layer display divided into: main display and

sub-display. The main display has a 10.0 x 5.0 mm figure size showing the count value and

the sub-display shows the preset values. Included in the display are preset level indicators and

output indicators which can be toggled by a push of a button.

The SLN-44 is available in 1 or 2 level preset type which makes it an ideal counter for

general counting or total/batching counting applications. It is 100 - 240V AC or 12-24V DC

powered and has an external power supply of 12V DC for sensors. The SLN-44 can count

bidirectional (Quadrature), Add, ubtract or Add/ ubtract and upon reaching the preset

value/s, the built-in output relays are actuated.

Functional modes, operation modes and output modes are fully programmable with the

menu driven display using the front panel buttons. Functional modes includes: count speed

(upto 10 kHz), input signal (contact / open collector or voltage), prescale, decimal point

position, key protection and free write. It has a built-in EEPROM memory to avoid loss of count

during sudden power cut. The front panel protection is IP 54. Wiring connections is secured

with the terminal screws.

This makes the SLN-44 the most versatile and functional preset counter even for the

complicated applications such as packaging (batching), converting (prescale), cut-to-length

and many more.

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 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.

User manual for electronic preset counter SLN-44

Attached with the unit please find:

- user’s manual,

- accessories (gasket, clip and terminal cover).

4.2. ASSEMBLY

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

switchboard) assuring appropriate protection against electric impulse waves.

Metal housing must be connected to the grounding in a way complying with the

governing regulations.

- Disconnect the power supply prior to starting assembly.

- Check the correctness of the performed connections prior to switching the unit on.

In order to assembly the unit, a 45 x 45 mm mounting hole (Figure 4.1) must be

prepared. Place the unit in the mounting hole inserting it from the front side of the

panel, then install the clip into the rear of the counter, push forward and clamp into

4.3. WIRING AND REAR TERMINALS

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 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.

- 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.

- 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). uch cables

should cross at a right angle.

- Use of screened signal cables is recommended. ignal 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 R -485

serial transmission connections.

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

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 measurement signals are executed using the screw

connections on the back of the unit’s housing.
