• Note: Some of the functions/parameters (manual control and TCP/IP
configuration) cannot be modified when using ECD-002 comparing to a set-up by
PC via TCP/IP.
•
Warning:
All alarms are disabled during manual control. We do not recommend
unattended operation of system during manual control.
• The parameters can be accessed via the 4-button keypad. The configuration
parameters are protected by a numerical password. The default password is "12".
To select the parameter configuration:
• Press the PRG button for more than 5 seconds, a flashing "0" is displayed
• Press
or
until "12" is displayed (password)
• Press SEL to confirm password
• Press
or
to show the code of the parameter that must be changed;
• Press SEL to display the selected parameter value;
• Press
or
to increase or decrease the value;
• Press SEL to temporarily confirm the new value and display its code;
• Repeat the procedure from the beginning "press
• To exit and save the new settings: Press PRG to confirm the new values and exit
the parameters modification procedure.
• To exit without modifying any parameters: Do not press any button for at least
60 seconds (TIME OUT).
S p e c i a l F u n c t i o n s :
The Special Functions can be activated by:
• Press
and
together for more than 5 seconds, a flashing "0" is displayed.
• Press
or
until the password is displayed (default = "12").
If password was changed, select the new password.
• Press SEL to confirm password
A "0" is displayed and the Special Function mode is activated.
• Press
or
to select the function. The number of special functions is dynamic
and controller dependent. See list below.
0: Reset controller to factory settings (this action is possible only when digital
input is 0V i.e. open).
1: Displays the current TCP/IP address.
2: Assign temporary 192.168.1.101 as TCP/IP address if EC3-X32 has different
Address.
• Press SEL to activate the function without leaving the special function mode.
• Press PRG to activate the function and leave the special function mode.
