Setting of parameters
The TCY3 is an
intelligent
controller and can be adapted to fit perfectly into your application. The control operation is
defined by parameters. The parameters are set during operation by using the standard operation terminal.
The parameters are password protected. There are two levels of parameters: User operation parameters for access control
settings and Expert parameters for control functions and unit setup. The passwords for user levels and expert levels are
different. Only control experts should be given the control parameter password.
The parameters can be changed as follows:
1.
Press UP and DOWN button simultaneously for three seconds. The display will indicate the firmware version in the
upper large digits and the revision in the lower small digits. Pressing any key will show: CODE.
2.
Select a password using UP or DOWN buttons. Dial 009 in order to get access to the user parameters.
Press OPTION after selecting the correct password.
3.
Once logged in, the parameter is displayed immediately
4.
Select the parameters with the UP/DOWN keys. Change a parameter by pressing the OPTION key. The MIN and
MAX symbols show up and indicate that the parameter may be modified now. Use UP and DOWN key to adjust
the value.
5.
After you are done, press OPTION or POWER in order to return to the parameter selection level.

Press the POWER key again so as to leave the menu. The unit will return to normal operation if no key is pressed
for more than 5 minutes.
