LAMP TEST
When it is desired to verify the display efficiency, put the
instrument in "normal display mode" and push

t and MENU

push-buttons for more than 5 s.
The instrument will light up, with a 50 % duty cycle, all the LEDs
of the display (we define this function "LAMP TEST").
No time out is applied to the LAMP TEST.
When it is desired to come back to the normal display mode,
push any push-button.
During the LAMP TEST the instrument continues to control the
process.

MANUAL MODE
MANUAL mode can be activated automatically at the end of a
program execution or manually when the instrument is in in
STAND-BY mode or it operates in controller mode.
It can be accessed:
- by depressing the MAN push-button for more than 1 sec or
- by acting on a logic input configured as "Au.ñA" (auto/manual

selection).

The command from keyboard is accepted and executed only if
the instrument is in "Normal Display Mode" while the command
from logic input is always accepted.

When in MANUAL mode the LED's MAN lights up while the
middle display shows "ñ." followed by the main output values
(from 0.0 to 99.9%) and the lower display shows "S." followed by
the secondary output value (from 0.0 to 99.9%).
When the device is configured with one control output only and
this output is “Servo”, the display will show the current valve
position.
When the device has two control outputs and one of them is
“Servo”, during valve positioning the display will show the final
position of the valve and not the current position.
The control output and/or the valve position can be modified by
using “

s”and “t”.

To come back to the AUTO mode, depress “MAN” push-button
for more then 1 sec. or toggle the logic input.
The transfer from AUTO to MANUAL is bumpless (this function
is not provided if an output value has been selected at
configuration parameter “Añ.UL” [C.G04]).
The transfer from MANUAL to AUTO is bumpless or bumpless
balanceless (the bumpless feature is not provided if integral
action is excluded).
When the instrument operates in controller mode, if transfer from
AUTO to MANUAL is performed during the first part of SMART
algorithm (TUNE) when returning in AUTO the device will be
forced, automatically, in the second part of the SMART
algorithm (ADAPTIVE).
