VEK CN1
The digital counter VEK CN1 is designed to control small medium car-parks. Four counting inputs are used to
accept outputs from loop detectors and/or traffic gate controllers. The counting inputs increment or decrement the
counter and is displayed on the 4-digit display. The output relay is used to turn on/off traffic signs or lot full signs.
Available open space counter and counter hysteresis are adjustable. The output relay can be used to directly
control a traffic light or a lot full sign.
Characteristics
• Especially developed for small to medium car-parks
• Vehicle counter and open space counter
• 4-digit display
• Totalize counter -999 … 9999
• 4 universal inputs with noise suppression
• Inputs function individually adjustable for increment, decrement or reset
• 1 reset input
• 1 relay output 150V, 5A for traffic lights and lot full signs (or others)
• Output function is adjustable for automatic, permanent free, permanent occupied
• Relay is adjustable to normally open or normally closed mode
• LED to display relay status
• 4 independent input counter up to 9,999,999 for statistical use independently displayed
• Available open space counter and counter hysteresis are adjustable
• Upper and lower counter threshold is adjustable
• 3 push buttons for user interface
• Power Supply 12..24 V DC/AC
• No loss of current data storage in case of power failure
• Display of temporary power failure
• Compact plastic housing 0.88 ” (22,5 mm) x 3.15 ” (80 mm) x 3.35 ” (85 mm), with DIN-Rail mounting

1.2 Operating Modes
The counting unit can be operated in mode “Open Space Counting” or in mode „Passing Vehicle Counting“. The
choice of operating mode occurs with set up the switching threshold. (see 2.4.1 Operating Modes switching )

1.2.1 Operating Mode “OPEN SPACE COUNTING”
The “OPEN SPACE COUNTING” is preferably used when the counting reading of the parking spaces is done
when the car-park is full so less open spaces has to be counted. Vehicles leaving the car-park will increment the
counter (Input 1) and vehicles entering the facility will decrement the counter (Input 2). The counter will activate the
output relay whenever the open space counter is equal or less than “0”. The output relay will be released as soon
the counter reached the adjusted counter hysteresis.

1.2.2 Operating Mode “PASSING VEHICLE COUNTING”
The “PASSING VEHICLE COUNTING” is preferably used when the counter reading of the parking spaces is done
when the car-park is empty so less occupied parking spaces must be counted. Vehicles entering the car-park will
increment the counter (input 1) and vehicles leaving the facility will decrement the counter (input 2). The counter
will activate the output relay whenever the vehicle counter reaches or is higher than the adjusted maximum. The
output relay will be released as soon the counter reaches or is lower than the adjusted lower counter hysteresis.
1.3 Pulse Inputs
The switching status of inputs is in normal operating mode displayed with four decimal points on the display. The
function of Inputs can be independent set on:
• increment
• decrement
• reset counter or
• no function
(see 2.4.3 Counter Level). Factory setting for input 1 and 3 is set to increment and for input 2 and 4 set to
decrement.
The inputs are interference-suppressed against switch bounces. Input pulses are counted separately of adjusted
function until 9.999.999. Each input pulse counter can be set up and reset separately. (see 2.3.4 Display and
Counter Reset).
1.4 Reset Input
With the Reset Input the counter reading can be reset to 0. The relay output will be adequate to the preferences set
on free or used. The adjustment parameters and the input pulse counter will not be changed. Is the output state
manually set on free or used (see 2.3.3 Set Relay Output manually to “Free” or “Occupied”) so the relay will stay in
this state.
