2. GENERAL CHARACTERISTICS
The electronic counters are popular, self-powered LCD totalizers (
SLE-42
) or hour
meters (
STH-42
) in a small form. With a panel size of DIN 48 x 24 mm, they are perfect for
limited space installations. They are powered by a replaceable lithium battery that lasts
approximately 7 years, no external power required. They are available in 7 digits with 8 mm
height figures with front reset or remote reset options. Input signal includes dry contact, open
collector, voltage, wide range voltage at maximum count speed up to 30 Hz. The front panel
protection is IP 54 and wiring connection is easily done via the terminal block connector,
making it secure and reliable. CE, UL and RoHS compliant.

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 2 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:
- user’s manual,
- warranty,
- accessories.
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 22,2 mm mounting hole (Figure 4.1) must be
prepared. Then follow the instructions mentioned below (Figure 4.2):
1. Insert gasket into the unit.
2. Insert the unit into the panel. Use the correct panel cut-out size.
3. Insert the mounting clip to the back of the unit.
4. Push the mounting clip until it locks the unit tightly against the panel.

4.3. WIRING AND REAR TERMINALS
Attention
- 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.
- 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.

4.4. MAINTENANCE
The unit (except battery) 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.
Product marked with this symbol should not be placed in municipal waste.
Please check local regulations for disposal and electronic products.
4.5. BATTERY REPLACEMENT
Precautions when replacing the battery:
- Disconnect the wiring before changing the battery. Do not touch areas subject to
high voltages as this could result to an electric shock.
- Make sure that your body is free from static electricity before changing the battery.
- Use only 3.6V 1/2AA Lithium Battery for this unit.
1) Use a flat screwdriver or any appropriate tool to lift the groove in order to unfasten rear case
from front case.
2) Pull out the rear case from the main body.

3) Replace with a new battery. Make sure that the positive and negative terminals of the
battery are positioned correctly.
4) Replace the rear case to the main body.
Warning!
This unit uses Lithium battery. Properly dispose the battery after use.
Do not short the positive and negative terminals, recharge, disassemble, deform,
or dispose the battery to fire as this may seriously damage it or may cause
explosion.
