1.2 Backup
All the parameters for the clock are saved permanently even in the absence of power supply.
However, the date and time (time basis) are not saved by the clocks with batteries.
The clocks powered by external low voltage (+6/24V) keep their time bases during a few days
thanks to their internal battery.
II - INTRODUCTION TO THE
CRISTALYS
CLOCK
The
Cristalys
14 clock is a calendar clock for indoor use, with batteries (type LR14).
The service life of the batteries is over 3 years.
As an option, a bracket (reference 938907) for low voltage power supply (6 to 24V AC or DC)
permits to replace the batteries.
It displays the hours (in 12 hr or 24 hr mode), minutes and date. It automatically manages
summer-winter time changeovers.
An ECO function enables the display to be switched off at night between 11pm and 6am.
It has three menus for making adjustments :
- the
time setting menu
;
- the
configuration menu
;
- the
technician menu
, which is reserved for maintenance personnel.
Adjustments can be made using the two push buttons [SEL] and [+] located on the back of the
clock.
