| - | Then attach the extension cord to pins 2 and 4 on Vizy's terminal block. | + | Then attach the extension cord to pins 1 (ground) and 2 (12V) on Vizy's terminal block. (We recommend these pins because the solenoid's operating current may exceed Vizy's maximum I/O current of 1000mA, whereas the 12V signal can switch up to 4A. You can verify that the solenoid you're using consumes less than 1000mA with an ammeter and then you can use one of the I/O signals to switch the solenoid if you wish. If you're using a larger solenoid that consumes more than than 1.75A @ 12V, it will likely cause Vizy's 12V power supply to brown-out and reset Vizy.) |
