USER DEFINED SETTIGNS, pin headers. why?, and what's a Pin Header anyways?- Written by Mark Bernal STE

 

 

 

 

 

"Auto Open" is just 1 of 2 options the VFlex board provides you as an alternative to battery backup operation when there is a loss of primary power.

·         Installing a shunt or pin jumper here will Automatically Open the gate when incoming AC power is loss.

·         How does it work? It simple!

1.      The VFlex board monitors the 24VAC that it is receiving from the Power Harness green and white wires.

2.      When that power drops out, the board has no choice but to pull power from the batteries.

3.      This feature uses the batteries to open the gate and keep it open, until the board is supplied 24VAC again.

 

"Last Open" is the other option that the VFlex board provides you as an alternative to battery backup operation when there is a loss of primary power.

·         This option is my favorite of the two! Allows the gate to operate on the battery backup, but when the batteries become critically discharged, the Last operation will be to automatically Open the gate.... Last Open

·         Just like the Auto Open, the board is monitoring the 24VAC supplied to it.

How do we send 24VAC to the control board if you are supplying 110 or 230VAC to the operator??Well, that question will be answered in this blog sometime in the future. So keep checking back here.

 

"Pre-Warning" is a feature often used on industrial applications that require an audible or visual warning that starts 3 seconds prior to the gate moving.

·         Installing a shunt or jumper here will Initiates two triggers for an audio or visual warning, 3 seconds prior to gate motion, and will continue:

1.      Until gate reaches the closed limit: the “Magnetic Lock” terminals provide a contact between “COM” and “N.O.”.

2.      Until gate reaches either limit: the “AUX. PWR” terminals provide 24VDC to power an accessory.

 

“Sync” If you are not going to Synchronize a barrier arm with your Viking gate operator, then don't worry about it. But, for those of you that are, will or do, then this feature will make the task simple.

·         Once you activate this feature, with a shunt or jumper on the pin header, it's as simple as connecting four wires between the barrier arm control board and the VFlex control board.

·         Works perfect with the Viking B-12 Barrier operator and the Mega Arm with their K1 relay.

·         FYI, the Viking B-12 has been temporarily discontinued.

“EXT” Stands for Extra. It has been left open for future developments.
