DFCK
III
: scheduler module with
integrated clock
The DFCK
III
module allows the management of scheduled
daily and weekly events, in the
Domino
bus system. By
means of the CLOCK function (see the programming man-
ual) it is possible to manage a virtually unlimited amount of
outputs, each one having many turn on and turn off sched-
uled times; as an alternative, DFCK
III
module can manage
up to 15 different zones, with the advantages that each
scheduled time can directly be changed from one or more
DFTouch video-terminal (or other similar device).
For each zone it is possible to set 4 different activation time
intervals (4 times for turn on and 4 times for turn off) for
each of the 7 days of the week.
The main features of DFCK
III
module are:
internal clock with back-up battery and automatic
change between daylight saving and standard time
management of 15 different zones (outputs)
daily and weekly programming for each zone
possibility to enable/disable each scheduled time
calculation of sunrise and sunset times
calculation of sun position (azimuth/elevation)
possibility to install more DFCK
III
(with different ad-
dresses) in the same plant
possibility to set a MASTER clock and some different
SLAVEs (these ones will be synchronized to MASTER)
A 2-way terminal block allows the connection of the module
to the
Domino
bus; as for almost all module of the
Domino
family, the needed supply is derived from the bus.
Near to the bus terminal block, the module features a small
pushbutton for the assignment of the address and a green
LED that shows the operating status; the same green LED
normally flashes every 2 seconds about to signal that the
module is properly supplied and operating.
A small 3-way connector (PRG), under the cover of the bus
terminal block, allows the connection of the optional
tester/programmer.
DFCK
III
module is housed in a standard DIN 2M box for
rail mounting. The user interface can be easily realized by
DFTouch (with special dedicate page) or by a generic
video-terminal.
Note: this manual applies to DFCKIII with firmware version 2.0
or higher.
Address programming
DFCK
III
module takes 1 input address made by 16 points
(15 for the zones and 1 for sunrise/sunset). The assign-
ment of the address module must be executed by DFPRO
or using the proper specific tools (BDTools or DCPIDE); the
address must be in the range 1 to 255.
Since more DFCK
III
modules can be installed on the same
bus, to identify which is the MASTER module and which
are the SLAVE modules, it is necessary to assign an identi-
fication number (ID) by means of the configuration panel in
BDTools (see the related paragraph).
The IDs must be in the range 1 to 8 with the following
meaning:
ID = 1
MASTER module
ID = 2
¸
8
SLAVE module
Every clock circuit of a SLAVE module will be automatically
synchronized to the MASTER module timing.
WARNING: it's important to define, in the case of more
DFCK
III
installed on the same bus, only one MASTER
module (ID=1). If a DFCP controller has been installed
on the bus, each DFCK
III
must be configured as
SLAVE module.
