operation (this also happens if no key is pressed for at least 40 seconds).
Press
“OK”
to switch between the display of the parameter label and its numerical
value. To modify a parameter:
- from the display of its label or value, press
“OK”
and hold down for at least
three seconds
- the display will start to flash and will show the parameter value
- use the
“up” (
�
)
and
“down” (
�
)
keys to increase or reduce the value
- press
“OK”
to confirm the parameter and leave the modification (the display
will stop flashing)
Note: if no key is pressed for at least 40 seconds, the instrument leaves
the parameter modification without memorising the changes made.
During the display and modification of the parameters, the instrument
will continue to operate with the previously set parameters.
If “password 1” is enabled (access password to protect the settings entered-see
system menu), when the
“OK”
key is pressed from normal status the message
“- - - ”
will appear. To set the parameters, enter the previously set password
(a number from 0 to 255) with the
“up” (
�
)
and
“down” (
�
)
keys and press
“OK”
to confirm. If the password is entered correctly, the label of the first menu
will appear. Otherwise, the system will return to normal status.
Advanced programming
Access is gained to advanced programming from normal status by pressing and
holding down the p and q keys for at least 3 seconds.
Note: to reset the default values set in the factory, switch on the instru-
ment while holding down the “OK” key.
These parameters are grouped into eight menus, by type:
1) Regulation
(indicated with
[REG]
): set point, differential, neutral zone
2) Output
(indicated with
[OUT]
): output drive times, PWM cycle time
3) Digital input
(indicated with
[ING]
): function, delay time
4) Alarm
(indicated with
[ALR]
): output status in probe alarm, minimum/maximum
shift, differential, delay time, buzzer enable
5) Display
(indicated with
[DSP]
): set point limits, probe offset, resolution,
measurement unit, measurement filter
6) Sensor
(indicated with
[SNS]
): type of sensor, sensor parameters
7) System
(indicated with
[SYS]
): password, modification enable, operating mode
8) Advanced
(indicated with
[ADD]
): dependence, type, entry, differential/logic
All the parameters inside the menus and their values are listed in the section
that follows.

— [ALR]
alarm menu
— [DSP]
display menu
