INSTRUCTIONS FOR USE
- Ver.05 - 03/22 - PAG. 2
-
Via RS485 (only for ELK22MPM)
-
Via Ethernet (only for ELK22MPE)
Programming with RS485 or Ethernet can be done via, for example,
operator panel, PLC or computer.
We will indicate "external instrument" the set of all the instruments
that can connect to the centralizing devices.
The programming phases must reflect these steps:
-
Only one centralizing device
o
Power on the device
o
Programming the centralizing device with the
external device
o
Use the device
-
One centralizing devica with N slave device
o
Power on the centralizing deivce
o
Programming the centralizing device with the
external device
o
Connect a slave to the centralizer via bus (, see
Paragraph 4.6). Turn on the product and program
it with the external device connected to the
centralizer.
The external device cannot be
connected to a slave device.
o
Repeat the previous step for each slave in
possession.
o
Use the devices
After having programmed the various devices, it is possible to
control them with the external device connected
only
to the
centralizing device. The slave devices are connected with the bus
(see Paragraph 4.6) to the centralizing device but are controlled by
the external device.
The devices, if more than one, must be connected one by
one and programmed one by one. Each device has the same
default address. (see Paragraphs 3.2.1, 3.3.2 and 3.4.2)
3.2 – PROGRAMMING BY ELK22DKP KEYBOARD (only for
ELK22MP e ELK22MPM)
3.2.1 – DESCRIPTION
Only the ELK22MP and ELK22MPM models can be programmed
via the ELK22DKP keypad. Through the bus connection (see
Paragraph 4.6) it is possible to program the slave products
ELK22MPS. The keyboard connected to the ELK22MP or
ELK22MPM model can program and set the parameters of each
ELK22MPS connected via bus.
The default MODBUS address is 100.

FRONT PANEL DESCRIPTION (ELK22DKP)
1 – Key
: Used to access programming of the operating
parameters and to confirm the selection.
2 - Key
▼
: Used for decreasing setpoint setting, values to be set,
and for parameter or module selection. Long pressed in full menu
programming, it changes the access level of the selected
parameter. (See para. 3.1, 3.3). Long pressed in the menu for the
module selection performs the download of the parameters from the
module to the programming keypad. (See para. 3.5).
3 - Key
▼
: Used for increasing setpoint setting, values to be set,
and for parameter or module selection. Long pressed in full menu
programming, it changes the access level of the selected
parameter. (See para. 3.1, 3.3). Long pressed in the menu for the
module selection performs the upload of the parameters from the
programming keypad to the module. (See para. 3.5).
4 – Key
: When in programming mode, you can use it to quit
programming or to cancel the change of a parameter. During
normal operation, it enables the menu to select a module.
5 – 4 red digits:
Process value during operation, parameter
selected during programming.
6
– 4 green digits:
Setpoint value during operation, value of the
parameter selected during programming.
7 – LED 1
: It indicates OUT1 output status.
LED 2
: It indicates
OUT2 output status.
8 – LED AL
: It indicates the state of the alarm.
9 – LED B1
: In full programming mode, it indicates that the
parameter is not visible in the operator menu.
LED B2
: In full
programming mode, it indicates that the parameter is visible in the
operator menu.
10 – LED °C
: It indicates unit of measure in degrees centigrade.
11 – LED °F
: It indicates measurement units in degrees
Fahrenheit.
12 – LED REM
: In parameters programming mode, it indicates that
you are changing the selected parameter. In module selection
programming mode, it indicates that you are selecting a remote
module.
13 – Led MAN
: In module programming mode, it indicates the
download of a setting.
3.2.3- MODULE SELECTION
Pressing the button
lights up the
REM
LED to indicate that you
can select on which ELK22MP you want to connect to and interact
with the programming keypad.. The 4-color display displays the
read temperature while the 4-screen green display shows the
address of the ELK22MP you are currently selecting. Use the
▲
and
▼
keys to select the desired ELK22MP depending on the
address you set. Pressing the key
confirms the selection of the
ELK22MP with the displayed address.
3.2.4 - SETPOINTS FAST SETTING
The 4 green displays display always displays the setpoint set.
Pressing the
▲
key increases the value and pressing the
▼
key
decreases the value.
These keys act at one-digit steps, but if
pressed for more than half a second, the value increases or
decreases rapidly to allow quick access to the desired value. The
setpoint can be set with a value between the value programmed in
para.
“SSP”
and the value programmed in para.
“FSP”.
3.2.5 - PROGRAMMING THE PARAMETERS
To have access to the operating parameters of the device in the
installer mode, you must press the key
and hold it for about 2
seconds, while pressing the key
for user mode access. The
display will show
“SET”
and then
“PASS”
if a password for the
installer access is set. Use the
▲
and
▼
keys to enter the
password and confirm with
. The red display shows the code that
identifies the parameter, the green display shows the value set and
with the
▲
and
▼
keys you can select the parameter you want to
edit. Once the desired parameter is selected by pressing the key
, the
“REM”
LED lights up to indicate that you are changing the
parameter setting using the
▲
and
▼
keys. After setting the desired
value, press again the key
; the new value will be stored while,
pressing the key
, the new value will not be stored, then the
“REM”
LED will switch off. By using the
▲
and
▼
keys, you can
select another parameter and change it as described. To exit the
programming mode, do not press any key for about 10 seconds if in
user mode or 20 seconds if in the installer mode, or hold down the
key
until you exit the programming mode.
