Manual Manipulation: MAN lamp On means manual manipulation. Press SET key select
MV lamp is On, at this moment the window can be set to show the present between the
total power on running time and the whole running time of the motor or value. The
percent shows the location value of the value. When changing the manual manipulate
value, the unit will stop after running the set timing. When it is auto-tune, it displays the
running location value of value.
Auto-tune: the unit runs as PID mode
Auto/manual manipulate converts: Press A/M key to convert.
4. Value feedback signal calibrations
Feedback signal voltage/current: When it is input by voltage 0-5V, 1-5V, 0-10V or
current 0-10mA, 4-20mA, the unit should be calibrated by the factory. Otherwise the
user should calibrate on the spot.
Feedback impedance of value is less than 1K, the user should calibrate on the spot.
Steps are as follows:
Connect all wires, according to the instructions in manual. And then switch
on the power.
Press A/M key to make Man lamp On. Press SET key for more than 3
seconds entering parameter P,I,D...Select LCK and set LCK=000, and then
press SET key for more than 3 seconds again to enter the parameter
calibrate area.
Press SET key to select IN1, set IN1=rt, it means impedance input.
Press SET key, select and select nL1. At this moment, value motor will
close. Waiting for full range running time, till low location switch takes action.
Then press SET key to confirm. The unit will display 0.0 (low values
calibrate) at this moment.
Press SET key, select nH1. At this moment, value motor will open. Waiting
for full range running time, till high location switch takes action. Then press
SET and increase key at the same time, LED flashes, press SET key to
confirm. The unit will display 100.0 (high value calibrate) at this moment.
Feedback impedance of value is more than 1K
External impedance should be used to share partly of the full voltage to make it
about 60mV. Select the input signal IN1=Ln, and then calibrate as mentioned above.
