5.2 CONTROLLER SECURITY & ALARMS
5.2.1 Password security
Controller features password security for setting of parameter. A valid password is an alphanumerical code having
minimum three and maximum eight characters.
Units leave the factory without a pre-programmed password and the security function is not active. To activate the
security, a password must be programmed. Once that is done, security can be enabled.
5.2.1.1 Entering a password to gain access to parameters change
When the security function is active any changes to the system settings can be done only after a valid password was
entered. When the ENTER key is pressed to change a parameter, the display will show a message “Enter Password”
on the top line and a blinking cursor on the right hand side of the bottom line. Using INC and DEC keys scroll to the
first character of the password and press ENTER. The character will be substituted by an asterisk (*) displayed to
the left of the cursor. Enter all characters of the password the same way. If the password is less than eight characters
long press ENTER again after last character. If the entered password was correct the display will return to the
selected parameter ready for modification. If the entry was incorrect following will be displayed.
Wrong Password
There is no limit on password entry re-tries. To abort password entry any of the top row buttons should be pressed.
The display will return to the selected parameter. Once unlocked, the security is disabled until there is no keypad
activity for >1 minute.
