HART Loop Converter KFD2-HLC-(Ex)1.D(.**)
Editing device data: Relay
8.4.3 Start value and end value
Please remember the following when entering the
Start value
and
End value
:
•
Both values must be entered as floating decimal numbers in the unit selected under
Unit
section 8.1.4 and 8.2).
•
The start value must be 1 % smaller than the end value. This is checked by the device and a start
value bigger than the end value will not be accepted. In this case the end value must be entered
prior the start value.
8.4.4 Error current
The following table shows what the current output issues for each characteristic after a fault.
8.5
Relay
The following illustrations show menus for the relay outputs on the KFD2-HLC-(Ex)1.D.2W or KFD2-
HLC-(Ex)1.D.4S. For the current outputs, see section 8.4.
Pressing the OK key in the
Rel1
and
Rel2
menu items on the KFD2-HLC-(Ex)1.D.2W or
Rel1
to
Rel4
menu items on the KFD2-HLC-(Ex)1.D.4S gives you access to a menu for entering separate
parameters for the selected relay. The two or four menus are identical and are therefore described
only once.
On
indicates that the function of a relay (
Trip value
or
Fault indication
) is enabled. If you want to enable
a different function, first call it up with the
S
and
T
keys. Then press the OK key twice. After the first
OK, you can cancel with ESC.
