0...3 0 graphic terminal configuration
in cases 1, 2, and 3 the OFF command is
forced on start-up.
0=standard terminal
1=terminal with ON/OFF command
2=terminal with ON/OFF and control sensor
3=terminal with ON/OFF and high-limit sensor
To read or modify the configuration parameters:
1. Simultaneously press the SEL & PRG buttons
for about 5 seconds until 00 appears, signifying
that the password is ready to be entered;
2. Press the ∆ and ∇ buttons to enter the
password (77);
3. Press the SEL button to confirm the password. If
the password is not correct, the programming
cannot continue, otherwise the parameter A0
appears;
4. Press the ∆ or ∇ buttons to cycle through the
parameters Ax, bx and Cx, Set Point inclusive;
5. Press the SEL button to display the value of the
parameter - the unit of measure is displayed for
one second;
6. Press the ∆ or ∇ buttons to modify the value
(holding down the buttons increases the speed
of the change);
7. Press the SEL button to confirm the change and
move to the next Ax, bx and Cx of the
parameter selection (see Fig. 8.3.3);
8. You can display and alter the subsequent
parameters by repeating steps 4 through 7;
9. Press the PRG button to permanently enter the
new values into memory and terminate the
programming mode.
10.4 Validation of the Modified Parameters
The modifications made to the parameters normally take effect when confirmed with the SEL button, and are
saved permanently with the PRG button. For some parameters relating to the serial connection, the value will
only take effect the next time the unit is switched on. During the programming phase, 5 seconds after the last
button is released, the display begins flashing (to remind the user that the programming phase is in progress).
Sixty seconds after the last button is released, if the value of a parameter is being displayed, any modifications
are ignored and the display returns to the parameter's ID code. After a further 5 seconds, the display begins
flashing again, and after 60 seconds the programming phase is terminated and the parameters return to the
values previous to the programming phase. If, on the other hand, the parameter's ID code is being displayed,
the programming phase is terminated directly after 60 seconds (time out).
