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.
To get the relay functioning as well, you need to connect the 12 V supply to the SK1 screw connector.
You can disconnect the USB cable and test the timer operation as a stand-alone device with the 12 V supply.
There are two inputs on the board; IN1 and IN2 for remote switches or NPN transistors to control the timer
operation. The switch or transistor connected between IN1 and GND acts as the Start button (TST1) and the
switch or transistor connected between IN2 and GND acts as the Reset button (TST2).
Relay output
The relay contacts are connected to the SK3 connector:
• COM: Common
• NO: Normally Open
• NC: Normally Closed
Space is provided on the board for a transient suppressor (option) to reduce contact wear. Mount VDR1 for sup-
pression of the NC contact. Mount VDR2 for suppression of the NO contact.
