Electronic safe lock
When a micro switch is connected to input 2 and the closed micro switch indicates the status
"door open", both checkboxes "Invert input (open contact to trigger)" and "door contact"
must be selected in AS284-USBW or AS284-NETW programming software for a smooth op-
eration.
It is possible to connect additional external signals to the lock terminal block.
It is possible to change the function and polarity of inputs and outputs with AS284-USBW or
AS284-NETW programming software.

Potential-free
contact
Do not apply any voltage,
potential-free contact
only.
Use a suitable micro
switch with gold-plated
contacts
12VDC/50mA (e.g. DB se-
ries by Cherry).
If input 2 is assigned as
"door contact" and not
inverted, an open switch
contact is used as "door
open".
The bolt is as long open as
terminals 7 / 8 are electri-
cally disconnected.
