5. Parameter – Overview
Setting depends
on model
(0.0...400.0°C)
(32.0...752.0°F)
If the maximum temperature exceeds,
the heating and cooling are inactive and
the maximum temperature LED lights up
on the controller.
Temperature
deviation control
(Deviation between
set and actual
temperature)
5.0°C / 9.0°F
(0…20.0°C)
(0…36.0°F)
The limit determines the maximum
deviation from the nominal value, which
is still tolerated. If the actual temperature
outside the set point window the alarm
will sound and the Temperature
deviation control LED lights. If the restart
lock (P24) is turned on, the temperature
deviation control is active only when it
reaches the set temperature. A set point
changes the start-up lock again.
Flow measurement
function
If the automatic flow measurement is
enabled, after 20s the measured flow is
stored and monitoring is enabled. The
green LED lights up.
(P3) set to manual
Alarm is triggered when the set value is
exceeded.
Change the temperature unit:
When the unit started the selected unit
will be indicated for a short time.
Setting depends
on model
1: Fe-Ko J
2: NiCr-Ni K
3: Pt 100 2-Draht
4: Pt 100 3-Draht
Selection of temperature sensor
Temperature
adjustment on Pt 100
0.7°C / 33.3°F
(0.0...130.0°C)
(0.0...234.0°F)
When using very long sensor lines
(Pt 100) the resistor of the line can be
compensated. A compare measurement
is needed. For example:
measured temperature: 100°C
indicated temperature: 108°C.
-> set 8°C (difference)
1: Voltage 0-10V
2: Current 0-20 mA
3: Current 4-20 mA
Analog input for setpoint selection.
0-10 V (switching threshold <0.1V)
0-20 mA (switching threshold <0.5mA)
4-20 mA (switching threshold <0.1mA)
