↑
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.

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:
Button Function
M Short Next Menu, next digit, Cancel settings.
(Mode) Long Activate System menu, Save changes, exit menu.
∧Short Display value increments + 1
(UP) Long Display value fast increments
∨Short Display value increments – 1
(DOWN) Long Display value fast decrements
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.

Power save mode
Note:
1. If one of the four (4) input counter display is activated the display will not switch back to normal operating
display by itself.
2. If the Power save mode is activated the display will turn off when the unit was idle for more than 30 sec. By
pressing the M-Button the display can be turned on again (see 1.4.6 Power Save Mode)

1.3 Base menu – Setting the operating modes
The base menu contains all settings for the different operating modes. The existing counts can be displayed,
modified and reset to original stage. The relay output can manually be set to “FREE” or “OCCUPIED”.

1.4.1 Operating Modes/ Switching point
The digital counter can be set to Operating Mode “OPEN SPACE COUNT” or " PASSING VEHICLE COUNT“ .
The two options can be selected by setting the Count threshold to:
Threshold = 0 (Default) →Mode “OPEN SPACE COUNT” see 1.4.1.1
Threshold = 1 = 1..9999 →Mode " PASSING VEHICLE COUNT“ see 1.4.1.2

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.
