13 ALARM TEMP
[ 50...85]°C
The alarm temperature programmed here is the temperature at which the
capacitor stages are disconnected in steps. The controller’s
alarm relay
responds after ten minutes. At the same time the display shows the cause of the
alarm (over-temperature). If the temperature drops again, the required
branches are automatically re-connected in steps.
The selection is performed with the
é
/
ê
keys. Save and continue with ENTER.
14 MESSAGE RELAY
this item appears if in ExpertMode2 the „alarm-relay“ is set as „message-relay“
The message relay can be programmed for
one
of the following options as
required:
"Fan”
:
Relay switches the external cabinet fan.
(Default)
The switching threshold can be programmed under point 15.
Display:
"F”
"Supply"
:
Message when active power is supplied. Display:
"S”
"Undercurrent”
This message appears whenever the measuring current is not
reached. Display:
"U”
The signal is generated when the value drops
below the response sensitivity of the controller.
"Harmonics”
: This message appears when the limit of the total harmonic distortion
THD-V is exceeded. This value can be set under "27 Harmonics” in%
15 FAN TEMP*
[15...70]°C
Input of the switching threshold for the fan.
BASIC SETTING:
[ NO ]
( YES / 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
(active / inactive / automatic after 24 h)
The device 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
mode. If the lock is active, all parameters can be checked but not changed.
* Only active
if
option 'Fan' is selected
27 HARMONICS (harmonic limit)
[7]%
(0.5 ... 25,5)%
A limit for the total harmonic distortion THD-V (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 uneven harmonics to the fundamental. A warning is
always shown in the display; an output via message relay only takes place
when this was selected in point 14.
