Eliwell IWK 32x74 User manual

IWK keyboards can be used for remote
access of IWP series power board functions
by displaying functional parameters and the
operating temperature.
The Split version of the Wide device consists
of two units:
• an IWK keyboard available in several
sizes*
• an IWP power module. The IWK keyboard
is connected to the IWP power module via a
“powered” serial connection.
*Different IWK keyboard models are
available: this technical data sheet
describes the Eliwell standard 32x74 IWK
keyboard. For information on other key-
boards, refer to the relevant technical
data sheets.

ACCESSING AND USING MENUS
LOCAL KEYBOARD PROGRAMMING
MENU
Hold down the “UP” and “DOWN” keys
for at least 3 seconds to access the
“Keyboard Local Programming” menu.
If specified, the access PASSWORD will
be requested (see parameter “PA3”) and,
if the password is correct, the PLO
(Local Parameters) label will appear.
This folder contains the keyboard
local parameters (see Keyboard Local
Parameters table).
If the password is incorrect, the display
will show the PA3 label again. NOTE: the
folder may NOT be visible; if this is
the case, keyboard local programming
cannot be accessed)
To enter the folder, press “set”. The label
of the first visible parameter will appear.
To scroll through the other parameters,
use the “UP” and “DOWN” keys.
To change the parameter, press and
release “set”, then set the desired value
using the “UP” and “DOWN” keys and
confirm with the “set” key. Move on to
the next parameter.
KEYBOARD LOCAL PASSWORD
Password “PA3” allows access to the key-
board local parameters. This password is
not present in the standard configura-
tion. To enable it (value<>0) and assign
it the required value, access the
“Keyboard Local Programming” menu in
the “PLO” folder.
If the password is enabled, it will be
requested when entering the “PLO”
menu.

1 — THE BASE UNIT/KEYBOARD PROGRAMMING/CONFIGURATION CANNOT BE CAR-
RIED OUT IF THE DEVICES ARE CONNECTED TO THE LINK NETWORK. THEREFORE, IT
IS FIRST NECESSARY TO CONFIGURE THE MASTER AND SLAVE DEVICES (WITH
RELATED KEYBOARDS) AND THEN CONNECT THEM TO THE LINK NETWORK.
2 — “FLICKERING” OF THE DISPLAYS ON THE KEYBOARD INDICATES THAT THE CON-
NECTED UNITS ALL HAVE THE SAME ADDRESS: DISCONNECT THE LINK NETWORK
AND PROGRAM EACH UNIT AS DESCRIBED ABOVE.
