• Choose in the menu range " Parameter
adjustment relay outputs " in the menu
item " Mode " the mode " Monitoring " for the
selected relay.
The selected relay becomes energised. By
pushing the key switch (opener opens), the
actual measured value is first of all frozen
and, derived from this, the relay deenergises
if this value is underrun (Low) or exceeded
(High). After a reset and a repeated pushing
of the keyswitch, the actual measured value
is again frozen.
