5.3 Programming Lock - janitza Prophi 12R Manual

Prophi 12R / 12 RS

15 FAN TEMP *
Input of the switching threshold for the fan. *Only active if option 'Fan' is selected
16 HARMONICS THD-V (harmonic limit) [7] %
A limit for the total harmonic distortion (in%) can be entered here. When this
threshold is exceeded, a message is given. THD-V is the ratio of the
geometric sum of the harmonics to the fundamental.
16 HARMONICS THD-I (harmonic limit)
see above, Preset is OFF (-,-)
17 HARMONICS

18 CONTRAST
Adjustment of optimal contrast for the display possible
19 - 28 Programming of all values of the 2nd parameter set (version /S485 only)
*only active if under „INTERFACE: 3 EXT. INPUT" the function
2
„2nd parameter set" is activated
From factory side the values of the 2nd parameter are set equal to the ones of
the normal parameters. By changing of particular parameters for example the
target cos-phi can be changed here. Other cases of application are transformer
switch over or change of switching times.
By applying a control voltage (110...230V) at the external input the 2nd
parameter set is activated with following indicated values:
19. CT primary,
23. Control principle, 24. Output 1st st., 25. Target cos-phi, 26. Switch-on time,
27. Switch off time,
29 Q-OFFSET
H ere an additional capacitive power is switched on independent from target
cos-phi and controlling - e.g. transformer direct compensation.
(value programmable via arrow-keys).
BASIC SETTINGS: [ NO ]
When the selection is made with YES and confirmed with ENTER, all parameters
are reset to the basic setting made by the PFC-system manufacturer.
(Optimal network values when the controller was supplied with a complete PFC-
system). If the controller is supplied from the works, this point corresponds to
the default setting.
CAUTION: All user settings are lost!

5.3 Programming lock

The PROPHI 12 is equipped with a programming lock to ensure protection from
unauthorized or inadvertent changes to the system parameters. The lock can be activated
in Expert Mode1 - item9. If the lock is active, all parameters can be checked but not
changed.
