Ramp Up - Set Point Ramp (Up); Ramp Dn - Set Point Ramp (Down); Exit - Back To Work Level - ABB TZIDC Manual

TZIDC, TZIDC-200 DIGITAL POSITIONER | COI/TZIDC/TZIDC-200-EN REV. B
RAMP UP – set point ramp (up)
Here the stroke time for the actuator can be increased. A
setpoint change is not directly transferred to the positioner;
instead, the speed is reduced accordingly. The set value should
always be greater than the shortest stroke time determined
during auto adjust.
Note
To display the stroke time (stroke time up), press and hold the
ENTER button.
CAUTION
The setpoint ramp is deactivated in the case of any functions
which involve approaching the safe position. This even applies
in the case of errors.
The actuator will therefore move without delay.
• Do not reach into the adjustment mechanism.
RAMP DN – Set point ramp (down)
Here the stroke time for the actuator can be increased. A
setpoint change is not directly transferred to the positioner;
instead, the speed is reduced accordingly. The set value should
always be greater than the shortest stroke time determined
during auto adjust.
Note
To display the stroke time (stroke time up), press and hold the
ENTER button.
CAUTION
The setpoint ramp is deactivated in the case of any functions
which involve approaching the safe position. This even applies

EXIT – Back to work level
With this parameter you can leave the configuration level. The
positioner returns to the operating level. Here you can either
save data in the non-volatile memory or discard all previously
made changes (also the changes in other parameter groups).
To exit the configuration level (with or without saving), press
and hold the ENTER button, until the countdown has run from 3
to 0 and finished.
The active saving process is indicated by the message NV_SAVE.
After saving a plausibility check is executed.
If an error occurs during the check or while saving, the data
cannot be saved and an error message is displayed instead (see
Chapter Error codes on page 40).
Selection
NV_SAVE Saves settings in the non-volatile memory.
CANCEL Discards all changes made since the last permanent
save operation.
