VEK CN1

Optional 4-pin plug for RS485-Interface

The digital counter VEK CN1 is designed to control small to medium car-parks. Four (4) counting inputs are used to accept outputs from loop detectors and/or traffic gate controllers. The counting inputs increment or decrement the count 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 count hysteresis are adjustable. The output relay can be used to directly control a traffic light or a lot full sign.

Characteristics

Digital counter is specifically developed for small to medium car-parks.

• Vehicle count and open space count.

4-digit display

• Totalize counter -999 bis 9999

4 noise immunity inputs, each function + / - Reset individually adjustable

• 1 Reset input (optional)

1 Relay output 250V, 5A for Traffic lights and Lot Full signs (or others).

• Output 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 counters up to 9,999,999 for statistical use independently displayed.

• Available Open space counter and count hysteresis are adjustable.

Upper and lower counter threshold is adjustable.

• 3 push buttons for user interface.

Power Supply: 12..24V DC oder AC

• No loss of current data storage in case of power failure.

Alarm display when power is/was lost.

• Optional RS485-Interface for data polling, setup or direct communication with a traffic sign.

Compact Plastic housing 0.88” (22,5mm) x 3.15” (80mm) x 3.35” (85mm), with DIN-Rail mount.

1.2 Display and Setup

1.2.1 User interface buttons

The VEK CN1 digital counter is adjusted with the three (3) user interface buttons located on top of the unit. The display shows the current menu and status of the setup. The buttons have following functionality:

Two simultaneously Cancel changes, back to operating mode.

The menu is divided in base menu and system menu. During setup the flashing display signalizes that the settings aren’t saved yet. If the unit was idle for 30sec. the unit goes back to normal operating mode without saving the changes.

1.2.2 Power Failure

During loss of power the current count values and setup are saved. When the power returns the unit goes back in normal operating mode but signalizes with the flashing display that there was a loss of power and the open space count must be checked and if necessary updated.

1.2.3 Display during normal operation

In normal operating mode you can have the display show either how many vehicles entered the car-park or how many open spaces are left (see 1.4.1Operating Mode/Switching point). The relay status is displayed with the

LED-Light. The input status are displayed with 4 dots. Special statuses are directly displayed.

The two options can be selected by setting the Count threshold to:

Threshold = 0 (Default)

Threshold = 1 = 1..9999

1.4.1.1 Operating Mode “OPEN SPACE COUNT“

The “OPEN SPACE COUNT” is preferably used when the control audit count 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 count

(Input 1) and vehicles entering the facility will decrement the count (Input 2). The counter will activate the output relay whenever the open space count is equal or less than “0”. The output relay will be released as soon the count reached the adjusted count hysteresis.

1.4.1.2 Operating Mode „PASSING VEHICLE COUNT“

The “PASSING VEHICLE COUNT” is preferably used when the control audit count 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 count (Input 1) and vehicles leaving the facility will decrement the count (Input 2). The counter will activate the output relay whenever the vehicle count reaches or is higher than the adjusted maximum. The output relay will be released as soon the count reaches or is lower than the adjusted lower count hysteresis.

1.4.2 Count Hysteresis

With the count hysteresis you can set the amount of vehicles that have to leave the facility after the “OPEN

SPACE COUNT” or the “PASSING VEHICLE COUNT” have reached the maximum and triggered the output relay.

Factory default is 1.

1.4.3 Upper Count Level and lower Count Level

The maximum and minimum range of the total count can be adjusted using this menu. This enables the counter to automatically adjust the total in case the maximum or minimum level is reached to prevent a wrongful count to continue. The default is 9999 for the upper and –999 for the lover level.

2 Installation Instructions

2.1 Input voltage

All inputs are provided with Opto couplers. To activate the inputs you can either use the internal switching voltage or use an external supply. When using an external supply you must first change the internal jumper setting of the control board. To do so carefully open the controller housing and set the jumper J2 in accordance with the drawing and table below.

Attention! The control board consists of electrostatic sensitive components. If working on the control boards please use electrostatic save measurements to prevent any damage to the components. Do not touch the board or any of the components! alternativ alternativ either

2.2 Reset Input (optional)

Using one of the inputs as count reset input all counts can be reset to 0 when a signal is applied. According to the relay output setting the relay switches to “OPEN” or “OCCUPIED”. The reset does not effect the adjusted parameters.
