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 (see
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.

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
OK, you can cancel with ESC.
