The Lock is delivered with the Bolt retracted and ready for
mounting. Do not move the cam (part with square hole) or the
bolt. During installation the bolt must stay in retracted position
and cam lined up as shown right.
1
Prepare the mounting and cable / spindle holes
2
Remove the small combination dial in the middle of the input unit
and remove the spacer ring. (do not throw away!)
3
Put the input electronic cable through the hole in the container door.
Be sure cable is inserted down into the slot in the back of the
keypad housing. Mount the input with two entry screws M4. Do not
tighten the screws yet.
4
Using the mounting screws, mount the lock in the correct position on
the inside of the safe door. Take note of any modifications that may
be needed to accommodate a relocker. Use Loctite to secure the
screws (approximately 3.5 Nm torque). Plug the four input’s prong
connector into the ENT slot of the lock. Thereafter, press the nose of
the plug lightly behind the metal housing so that it does not come
loose during use.
5
Cut the shaft for the mechanical dial and deburr both ends. Length:
41 mm + D
(=door thickness). Insert the cut shaft into the square
hole of the DIAL.
6
Align the input unit (with mounting tool LS-1526) and tighten the 2
screws (hand tight)
7
For a first test, place the previously removed spacer (see 2)
between the dial and the keypad housing. With the bolt still
retracted, push the dial lightly into the keypad hole on approximately
number 93 of the dial.
8
Turn the dial LEFT to extend the bolt. In the LOCKED position, there
should be approximately 1 mm clearance between the lock bolt and
the cavity in the blocking bar of the boltwork. The lock bolt must
move freely into the cavity. Turn the dial several times to assure that
it turns freely.
