BUILTIN RELAY  BACK EMF PROTECTION
The Art.4833 includes selectable back EMF protection on the relay. The jumpers marked J4 is used to select the protection type.
When using a fail secure lock with connections C & NO the jumper should be in the NO position. When using a fail open lock with
connections C & NC the jumper should be in the NC position and when used to trigger a gate controller or another third party con-
troller the jumper should be removed completely (This disables the protection on the relay).
LOCK RELEASE BACK EMF PROTECTION
A varistor must be tted across the ter-
minals on AC lock release (Fig. 3) and
a diode must be tted across the ter-
minals on a DC lock release (Fig. 4) to
suppress back EMF voltages. Connect
the components to the lock releases as
shown in gures.
