Frequently Asked Questions - Typ 901 Kübler

What does the "noFunc" display mean?

The message noFunc indicates that the battery is discharged. The device switches to safety mode: it no longer counts and the relay remains in the last position. Replace the batteries (see manual) and reprogram the device.

How to replace the batteries of the Kübler Typ 901?

Disconnect all voltage, unplug the connector, slide the cover backwards, remove both batteries and insert new ones respecting polarity (negative pole on - mark). Replace one battery at a time to avoid losing settings (more than 20 s absence leads to reprogramming). Use batteries of reference N060045 (Tadiran Lithium SL350/S 1/2 AA 3.6V).

How to set the preset value?

Use the 6 decade keys to modify the value displayed on the lower line. The new preset is taken into account at the next reset (Set key or pulse on the reset input).

How to enter programming mode?

Press simultaneously the Reset key and the keys of the 5th and 6th decades. The display shows INIT then a countdown from 5 to 0. Release the keys at INIT 0 to enter programming. Parameters are set with the decade keys.

Why does the counter not count?

Check: the connection of the counting input (terminals 5 and 7); correct polarity; signal level reaches the switching threshold (HIGH: 12-250 V AC/DC or 2.5-30 V DC depending on model); common ground; and that the key lock input is not activated.

How to test the display?

Press simultaneously Reset and the keys of the 5th and 6th decades. The display shows INIT 5. Release immediately: all segments light up. If you hold the keys, you enter programming and lose settings.

What is the battery life?

The minimum life is 8 years at 25°C for 5×10⁶ relay switchings. It depends on ambient temperature and number of switchings. Replace batteries as soon as the message Lo-bat appears to avoid entering safety mode.

How to configure the relay output as momentary or bistable?

In parameter dELAY: set a value between 0.01 and 99.9 seconds for a momentary signal; set 0.0 for a bistable output (active until reset, only if LooP is off). For LooP on, 0.0 is automatically set to 1.0 s.

What to do if the display flashes?

A flashing display can indicate: an overflow (counter resets to zero) or a low battery (message Lo-bat). In the first case, counting continues; in the second, replace batteries quickly.

How to lock the front keys?

Apply a voltage of +3 VDC to terminal 2 from terminal 1. All keys (including Set) are then disabled. To unlock, remove this voltage.

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 proper operation. Information about the prescribed fuses can be found in the technical data.

The relay output is not protected / overcurrent-limited internally in the device. Without suitable protection of the relay output, undesired heat development or even fire may occur. The relay output must be protected externally by the manufacturer of the plant. It must also be made sure that, even in case of a malfunction, the values stated in the technical data are under no circumstances exceeded.

During installation, make sure that the voltage of the counting and reset inputs and the wiring of the output contacts are both powered by the same mains phase, in order not to exceed the maximum permitted voltage of 250V.

The cables and their insulation must be designed for the planned temperature and voltage ranges. Regarding the type of the cables, adhere to the applicable country and final device standards. 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.

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.

Measures

• Use only shielded cable for signal and control lines. Connect cable shield at both ends. Minimum cable conductor cross-section 0.14 mm² .
• 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-conducting cables.
• Avoid routing signal or control cables parallel to power lines.

1.7 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.

1.8 Start-up

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

1.9 Failure possibilities and causes

2. Inputs

2.1 Reset input terminal 6

This input is connected functionally in parallel with the red Set key and sets the counter to zero in case of adding counting and to the pre-set value in case of subtracting counting. The reset function is dynamic.

2.2 Counting input (Start input) terminal 5 Input damped to 25 Hz for pulse counting with the pulse preset counter or static start input with the time preset counter (time counting active when input is active, time indicator located on top left flashes when time counting is active).

Note: The reset input (terminal 6) and the counting input (terminal 5) are inputs with a common connection (terminal 7) and must be controlled with the same polarity.

2.3 Key lock input

Tre front keys (including the set key) are locked when this input (terminal 2) is set to +3 VDC (terminal 1).

3. Output

Relay with potential-free contact, contact programmable as normally open or normally closed (terminal 3 and terminal 4). For the adding count, the relay is activated when > preset value, for the subtracting count, it is activated when < 0. The output signal is programmable as a fugitive signal between 0.1 and 99.9 seconds or as a bistable signal with the setting 0.0 (Loop OFF) no automatic repetition. When the relay is active, a colon symbol is displayed on the left end of the lower row. The output relay shall not exceed a switching frequency of 4 Hz.

4. Setting the operating mode and the operating parameters

4.1 New installation

In case of a new installation of the counter, after a battery replacement that lasted more than 20 seconds, or if the counter switched over to the „NoFunc“ safety mode because of a too low battery voltage, the preset counter switches automatically to the programming mode. All parameters must then be input again (see 4.2). Parameter modification is also possible during operation. For safety reasons, to access the programming mode, the reset key and the keys of the 5th and 6th decades must be pressed simultaneously. The lower display line then displays the message INIT. If these 3 keys remain pressed, a countdown from 5 to 0 takes place in one-second intervals. If the keys are released

during this countdown, the device switches back to the previous operating mode. If the keys are released after 0 is reached, parameter setting is activated and the first parameter is displayed.

4.2 Setting the parameters

The key of the 1st decade allows switching among the available parameters (e.g. add-sub) and the key of the 6th decade allows switching over to the following function. The duration of the fugitive pulse is set using the keys of decades 1-3. After the last input (dP), the key of the 6th decade allows jumping back to the start of the programming routine; pressing simultaneously the reset key and the keys of the 5th and 6th decades allows saving the parameters.

Note: Every time the programming routine is called up, the counter switches back to the basic parameter setting, i. e. the previous programming is lost and the counter and preset values are reset to zero.

4.3 Parameters description

(see also the function sequence)

Funct.Count: Pulse preset counter operating mode

Funct.Time: Time preset counter operating mode

tMode: Programmable time range (only for Funct.Time), SEC=seconds, Min=minutes, hour=hours

Count Add: Adding counting mode

Count Sub: Subtracting counting mode

LooP off: Automatic repetition off

When parameter LooP is „c

dELAY time is 0.0, the output is activated when the preset value is reached and remains activated until reset is performed.

LooP on: Automatic repetition on

When parameter „LooP is „on“, the counter is reset automatically and the output emits a fugitive pulse for the time of the duration set in dELAY.

rELAY no: Normally open contact

rELAY nc: Normally closed contact

dELAY: Output signal duration: fugitive

signal programmable from 0.01 – 99.9 seconds, 0.0 = bistable output (active until reset) programmable only for Loop off, in case of Loop on, 0.0 is set automatically to 1.0 second.

dP: Programmable decimal point:

pulse preset counter: 0 - 0.00000 only for display purposes, time preset counter 0 - 0.0 (seconds) 0 - 0.00 (minutes, hours) determines the resolution.

If the relay output is switched from „no“ to „nc“, the relay condition must be taken over by pressing the reset key.

5. Operating the counter

5.1 Setting or resetting

The red set key or a pulse on the reset input sets the counter to zero in adding mode and to the preset value in subtracting mode.

5.2 Preset setting

The preset value is displayed in the lower display line. Setting is carried out with the 6 preset keys, each assigned to a decade. The set or modified preset value is taken over at the subsequent setting or resetting of the counter.

5.3 Overflow or underflow

In adding mode, overflow passes from 999999 to zero, in subtracting mode from zero to 999999. The output signal remains unchanged. The display flashes in case of overflow or underflow. The counter stops after the overflow or underflow of an additional decade.

5.4 Lo-Bat indicator

In case of a too low battery load, the message Lo-bat is displayed and the display flashes. The batteries must be replaced when „Lo-bat“ is displayed. If the battery voltage decreases in such a way that safe relay switching cannot be ensured any more, the counter switches to Safe Mode and displays the message „noFunc“. In this mode, the device does not count any more pulses or times, and the relay remains in its

last position. Thys way, the user knows exactly whether the plant is operating optimally, which allows preventing malfunctions. After battery replacement in „noFunc“ mode, the device requires re-parameterizing. Please read chapter Battery replacement to that purpose.

Note: In order to avoid loosing the settings and values because of switching to Safe Mode, the service plan of the device should include timely battery replacement in function of the ambient temperature and of the switching cycles of the relay.

5.5 Battery replacement

Before replacing the batteries, disconnect the voltages or switch the device off. Disconnect the connector from the device. This also makes sure that no untimely pulses set the device in an undefined state during battery replacement. Then push the battery lid backwards and remove the 2 batteries. Position the new batteries so that the „-“ pole is connected to the battery holder marked with „-“ on the printed circuit. After battery replacement, the display may go on displaying the LowBat message for 2 more minutes. Pressing the reset key can shorten this delay, as the device checks the current battery voltage every time this key is pressed. However, this also resets the current counter value.

Important: If battery replacement lasts longer than 20 seconds, the parameters, the preset value and the current counter value can be erased. In order to prevent this loss of information, we strongly recommend replacing the batteries one after the other.

Only use the batteries described in the Technical Data. Otherwise, proper operation cannot be guaranteed.

5.6 Segments test

Segments test is activated by pressing simultaneously the reset key and the keys of the 5th and 6th decades. Init 5 is then displayed; release immediately the keys, the segment test is started and all display segments are displayed. Pressing the 1st decade key calls up the programming mode; all parameters must then be re-programmed.

9. Interference suppression measures

The following interference suppression measures may be required: if the output switches inductive loads (relays, solenid valves), interferences must be suppressed by means of a freewheeling diode for direct current and of an RC element for alternating current. For safe and EMC-compliant operation, use shielded cables for the control inputs (counting, reset and key lock inputs). The shield must be connected at both ends. If this is not possible, a capacitor (e.g. 10 nf) may be integrated on one side in the shield connection.
