Description No timer is universal, except this one! 2 reasons why this timer is truly universal: 1. The timer comes with a wide variety of operating modes. 2. If the built-in modes or delays don’t suit your application, you can simply tailor them according to your needs using the supplied PC software.
Plugging in your board for the first time First, you will need to plug your VM206 into an available USB port on your computer so Windows can detect your new device. Then download the latest software version for the VM206 on www.velleman.eu via these simple steps: 1. go to: http://www.vellemanprojects.eu/support/downloads/?code=VM206 2. download the VM206_setup.zip file 3. unzip the files in a folder on your drive 4. double click the “setup.
The VM206 is now programmed! You can check the operation by pressing the TST1 (Start) button. The ‘RELAY ON’ LED indicates the operation. You can stop the timer operation by pressing the TST2 (Reset) button. Power supply Heavy duty relay 12 VDC / 100 mA max. For inductive loads, add optional VDR (e.g., Velleman VDR300) 8 A / 250 VAC NO / NC Relay output Start - Stop Buffered inputs accept dry contact or open collector Status LEDs USB ICSP connector Start - Reset pushbuttons fig.
Description of the timer operation 1: On delay - relay turns on after delay t1 Timing begins on the leading edge of the Start signal. When the set time (t1) has elapsed, the relay contacts transfer to the ON state. The contacts remain in the ON state until the Reset signal is applied or power is interrupted. Start Reset Output fig. 3 2: Off delay - relay turns off after delay t1 When a Start signal is supplied, the relay contacts transfer immediately to the ON state.
Start Reset Output fig. 5 4: Repeat cycle - after delay t1, relay turns on for t2; then repeats Timing begins on the leading edge of the Start signal. A cycle is initiated when the output will be OFF for the first set time (t1), then ON for the second set time (t2). This cycle will continue until the Reset signal is applied or power is interrupted. Start Reset Output fig. 6 5: Repeat Cycle - relay turns on for time t1, off for t2; then repeats Timing begins on the leading edge of the Start signal.
6: Toggle mode When a Start signal is supplied, the relay contacts transfer immediately to the ON state. When the Start signal turns ON again, the relay contacts transfer to the OFF state and on the next Start signal to ON state etc. Start Reset Output fig. 8 7: Start/Stop timer When a Start signal is supplied, the relay contacts transfer immediately to the ON state and the set time (t1) begins. When the set time (t1) has elapsed, the relay contacts transfer to the OFF state.
: Trigger-at-release timer On the trailing edge of the Start signal the relay contacts transfer to the ON state and the timing begins. When the set time (t1) has elapsed, the relay contacts transfer to the OFF state. The timer is reactivated by applying the next trailing edge of the Start signal before the set time (t1) has elapsed. Start Reset Output fig. 11 10: Programmable timing sequence In this mode you can program a sequence of up to 24 timing events.
Relay state Time fields Timing event list fig. 14 Timing sequence user interface Options: • • • • • • add timing / insert timing delete timing copy timing repeat sustain the first state until Start signal is OFF auto start & repeat By selecting the option ‘Sustain ...’, the relay state of the first timing event is sustained as long as the Start signal is ON or the Start button is kept pressed down. Start Reset Output fig.
By selecting the option ‘auto start & repeat’, the timing sequence restarts automatically when the power supply is connected or when there has been a power outage. fig. 16 Normally the relay will be OFF after the last timing event of the sequence. The relay can be forced to stay ON by setting the time of the last ‘ON’ action to zero.
