5.6
Relay Switching Performance
Display information depends upon selected relay switching performance,
i.e. LoLo, LoHi, HiHi or HiLo.
Select the required function with the
⇑
and
⇓
keys. Save values to memory
with the P key.
5.7
Limit Value Switching Points
Depending upon the selected switching function, either Lo-1 and a numeric
value, or Hi-1 and a numeric value blink alternately at the display.
The numeric value corresponds to limit value 1.
Select the required value with the
⇑
and
⇓
keys. Save values to memory with
the P key. Depending upon the selected switching function, either Lo-2 and a
numeric value, or Hi-2 and a numeric value blink alternately at the display.
The numeric value corresponds to limit value 2. Select the required value with
the
⇑
and
⇓
keys. Save values to memory with the P key.
5.8
Setting Hysteresis
HYST and a numeric value blink alternately at the display.
The numeric value corresponds to the selected hysteresis in
±
format.
Select the desired hysteresis with the
⇑
and
⇓
keys. Save values to memory
with the P key.
5.9
Securing the Selected Limit Values
Either Uloc or Loc is displayed.
LoLo
=
Both relays for limit values 1 and 2 are active,
if the measurement value is less than the selected limit values.
LoHi
=
The relay for limit value 1 is active, if the measurement value is less than
limit value 1. The relay for limit value 2 is active, if the measurement value
exceeds limit value 2.
HiHi
=
Both relays for limit values 1 and 2 are active, if the measurement value
exceeds the selected limit values.
HiLo
=
The relay for limit value 1 is active, if the measurement value exceeds limit
value 1. The relay for limit value 2 is active, if the measurement value is
less than limit value 2.
Uloc
=
The selected limit values can be changed, even if programming is protected
against unauthorized or inadvertent changes by means of an external
connection between terminals 10 and 11.
Loc
=
The selected limit values are protected against unauthorized or inadvertent
change by the program protection function.
Then the limit values cannot be changed.
