6. Maintenance
For a reliable operation of the lock, a certain level of maintenance is required.
6.1 Lubrication
All parts that need lubrication are already lubricated by ASSA ABLOY Hospitality.
No parts should therefore need any further lubrication.
Caution:
The use of lubricants containing solvents or graphite will void the warranty
on the lock.
6.2 Loose screws and functional test
Check for loose screws, especially the door handle fastening screws, at scheduled
times. Also, perform a functional test (see
chapter 5
) at scheduled times; at least
once per year is recommended.
6.3 To replace the batteries
The
LCU 5351
(pos
11
in the exploded views of
section 4.3
) checks the battery
voltage when a staff card is used. The check is performed when the lock motor is
activated. If the battery voltage is below the acceptable, the
LCU 5351
signals with
four short yellow flashes. The door will still unlock as long as the battery voltage is
high enough to operate the lock motor; this gives a green flash. If there is no green
flash at the end, the battery voltage is below next critical level and will not operate
the lock motor.
Important:
Battery check and/or replacement should be performed at
scheduled intervals.
Important:
It is recommended to always make a read-out of the time in the lock
after a battery exchange to make sure that it is correct. Use a service cable and a
service PC with the software
Lock Service 3G
; see
Quick reference guide Lock Service
3G
for details. If the time is not correct, a soft reset has occurred; see details on how
to proceed in step 9 below.
To replace the batteries:

Important:
Make sure to have fresh batteries ready since the
battery holder

with new batteries must be connected as quickly as possible after the
old batteries have been disconnected, else a soft reset may take place.
Do not present any card during the battery exchange. If other batteries than
those provided by ASSA ABLOY Hospitality are used, make sure that they
