Manual of instructions TT-390 21/35
6.2. Parameter settings MP-888
Each unit requires a different programme setting. For each model is a programme defined that not
every parameter must be set manually. In this program the model specific settings are saved.
365.0°C / 689.0°F
(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 fallen short of.
Change the temperature unit
When the unit started the selected
unit will be indicated for a short time.
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)
0.0°C / 32°F
(-50.0...399.9°C)
(-58.0...751.8°F)
Lower scaling point of the voltage
analog input
0 V corresponds to 0°C
400.0°C / 752°F
(-49.9…400.0°C)
(-57.8…752.0°F)
Upper scaling point of the voltage
analog input
10 V corresponds to 400°C
Temperature
at 0/4 mA INPUT
0.0°C / 32°F
(-50.0...399.9°C)
(-58.0...751.8°F)
Lower scaling point of the voltage
analog input
4 mA corresponds to 0°C
