Frequently Asked Questions - Codix 134 Kübler

How to install the Codix 134 in a panel?

Remove the mounting frame, insert the device from the front into the cutout (22.2x45 mm), then slide the mounting frame from the back until it clicks. Ensure the gasket is properly positioned to guarantee IP65 on the front panel.

What types of inputs are available?

Two versions: DC (NPN/PNP) and AC (optocoupler 10...260 V AC/DC). Inputs include Timer Enable, Reset, key lock, and time range selection.

How to set the time range?

Use screw terminal No. 5 (Mode). For DC versions, a contact with GND switches between ranges (e.g., 99999h 59m or 99999.99h). For AC versions, the setting is similar. Reset after change to ensure repeatability.

What to do if the counter does not count?

Check the connection of the counting input (terminals 2 and 3), NPN/PNP polarity, common ground between generator and counter, and signal levels (switching thresholds). Ensure the Timer Enable input is active.

How to reset the counter?

Use the Reset input (terminal 3): for DC, active on negative edge (pulse ≥50 ms); for AC, active on high signal (10...260 V AC/DC). The electrical lock (terminal 4) can disable the reset button.

What is the battery life?

The built-in lithium battery has a life of about 8 years at 20 °C. It is not user-replaceable; at end of life, return the device to the manufacturer.

Can I use a backlight?

Yes, models with backlight option (x=6) require an external power supply 24 VDC ±20%, 50 mA on terminals 7 (-) and 8 (+). Use a slow-blow fuse T0.08 A.

What are the electrical safety precautions?

Before any intervention, disconnect all power sources. Use appropriate external fuses (rating specified in the specifications). Respect overvoltage categories (CAT II) and use suitable cables. SELV circuits must be double insulated.

How to clean the device?

Clean only the front panel with a soft damp cloth. Do not use solvents. The recessed back does not require cleaning. In case of malfunction, return the device to the manufacturer.

What to do in case of display range overflow?

If the value exceeds 99999999, the counter restarts from 0 without leading zero suppression and all decimal points light up. This indicates an overflow; no action needed, but check the set time range.

The device must compulsorily be protected with approved external fuses. The value of these fuses can be found in the technical information.

This symbol is used on the device to remind of the existence of dangers, which are referred to in this manual.

1.3 Use according to the intended purpose

The counter detects and measures pulses, times and frequencies and offers a wide variety of different operating modes. Use for any purpose over and beyond this will be deemed as not in accordance with its intended purpose and thus not complying with the requirements.

The application area for this device lies in industrial processes and controls, in the fields of manufacturing lines for the metal, wood, plastics, paper, glass, textile and other like industries. Over-voltages at the terminals of the device must be kept within the limits of Over-voltage Category II.

The device must only be operated when mounted in a panel in the correct way and in accordance with the section "Technical Data".

The device is not suitable for use in hazardous areas and for areas excluded in EN 61010 Part 1. If the device is used to monitor machines or processes in which, in the event of a failure of the device or an error made by the operator, there might be the risk of damaging the machine or causing an accident to the operators, it is your responsibility to take the appropriate safety measures.

The device has been designed for indoor operation. It may nevertheless be used outdoors, provided the technical data is adhered to. In this case, take care to provide suitable UV protection.

1.4 Mounting in a control panel

CAUTION

Mount the device away from heat sources and avoid direct contact with corrosive liquids, hot steam or similar.

Provide a free space of 10mm all around the device for its ventilation.

The device should be mounted so that the terminals are out of the reach of the operator and cannot be touched by him. When mounting the device, consider the fact that only the front side is classified as accessible for the operator.

1.5 Mounting instructions

1. Remove the mounting clip from the device.
2. Insert the device from the front into the panel cut-out, ensuring the front-panel gasket is correctly seated.
3. Slide the fixing clip from the rear onto the housing, until the spring clamps are under tension and the upper and lower latching lugs have snapped into place.

Note: In case of proper installation, IP65 can be reached on the front side.

1.6 Electrical installation

DANGER

The device must be disconnected from any power supply prior to any installation or maintenance work. Make sure that no more voltages LIABLE TO CAUSE AN ELECTRO-CUTION are present.

Signal lines carrying voltages exceeding 30V AC or 70V DC must be operated with a device allowing disconnecting them from the voltage source. This device must be located close to the equipment and marked as its disconnecting device - excepted when it can be excluded that a defect presents a danger.

Installation or maintenance work must only be carried out by qualified personnel and in compliance with the applicable national and international standards.

Take care to separate all extra-low voltages entering or exiting the device from hazardous electrical conductors by means of a double or reinforced insulation (SELV circuits).

DANGER

The device must be protected externally for its proper operation. Information about the prescribed fuses can be found in the technical information.

• During installation, make sure that the signal inputs are fed from the same mains phase, in order not to exceed the maximum permitted voltage of 250V .
• The cables must be designed for the planned temperature and voltage ranges. Regarding the type of the cables, adhere to the applicable standards of the country and of the plant. The cross sections allowed for the screw terminals can be found in the technical data.
• Before starting the device, check the cables for proper wiring and tightening. The screws of unused screw terminals must be screwed to the stop, so that they cannot loosen and get lost.
• The device has been designed for overvoltage category II. If higher transient voltages cannot be excluded, additional protection measures must be taken in order to limit the overvoltage to the values of CAT II.

1.7 Advice on noise immunity

All connections are protected against external sources of interference. The installation location should be chosen so that inductive or capacitive interference does not affect the device or its connecting lines! Interference (e.g. from switch-mode power supplies, motors, clocked controllers or contactors) can be reduced by means of appropriate cable routing and wiring.

1.8 Measures to be taken:

• Use only shielded cable and control lines. Connect shield at both ends. The conductor cross-section of the cables should be a minimum of 0.14mm^2
• The shield connection to the equipotential bonding should be as short as possible and with a contact area as large as possible (low-impedance).
• Only connect the shields to the control panel, if the latter is also earthed.
• Install the device as far away as possible from noise-containing cables.
• Avoid routing signal or control cables parallel to power lines.

DC versions

Use shielded wires for the counting and control inputs so as to obtain the maximum EMC resistance or connect not used count inputs to ground (0 V).

AC versions

Use shielded wires for the counting and control inputs so as to obtain the maximum EMC resistance.

1.9 Cleaning and maintenance

The front side of the unit should only be cleaned using a soft damp (water!) cloth. Cleaning of the embedded rear side is not planned and is the responsibility of the service personnel or of the installer.

In normal operation, this device is maintenance-free. Should the device nevertheless not operate properly, it must be sent back to the manufacturer or to the supplier. Opening and repairing the device by the user is not allowed and can adversely affect the original protection level.

1.10 Start-up

Is the device set and programmed correctly (function; for counters, max. counting frequency)?
