Standard setting of controller (programmed RESET of controller) –
In the case of problems with setting the parameters, proceed as follows:
- disconnect the supply voltage
- at the same time, press buttons SW1 and SW2
- switch on the supply voltage
-
keep the buttons pressed down until the yellow LED diode starts to flash which indicates that the basic
setting is complete.
Controller setting procedure:
The initialization routine starts at the switched-on controller, zero system deviation and short pressing of the
SW1 button for ca 2 sec (i.e. until the diode D3 got on). Loosing the button menu control signal starts, what is
shown with 1 blink on the D3 diode as well as one of the default parameters (usually control signal of 4-20mA)
what is shown with 1 blink on the D4 diode. Then the required parameters of the controller can be changed
according to Table 4:
•
press shortly the SW1 button to list the menu shown with the blinking number on the D3 diode.
•
press shortly the SW2 button to set parameters shown with the blinking number on the D4 diode.
After changing of the parameters according to user's wishes, put the controller to autocalibration with
pressing the SW1 button for ca 2 sec (i.e. until the diode D3 got on) , what is shown with 6 blink on the yellow
LED D3 diode.
During this process the controller performs the feedback transmitter and turning sense checking, sets actuator to
the positions "open" and "closed", measures inertia mass in the directions "opening" and "closing", and loads the
adjusted parameters into the EEPROM memory. In case that during the initialization process an error occurs
(e.g. in connection or adjustment) the initialization process will be interrupted and the controller with the
D4 diode
reports about the type of the error. Else after finishing the initialization process the controller is put into the
regulation mode.
Error messages of the controller with D4 diode at initialization
4 blinks..........improper connection of the torque switches
5 blinks..........improper connection of the feedback transmitter
8 blinks..........bad sense of actuator's turning direction or adverse connection of the feedback
transmitter
4.8.2 Watching operation and error states
Watching operation and error states is possible with the EA open.
a)
Operation status with the D3 LED diode indicating:
•
it is continuously lighting - the controller regulates
•
it is continuously not lighting - system deviation in the insensitiveness range - the EA has stopped
b) Error state with the D4 and D3 LED diodes indicating - D4 continuously lighting,
D3 indicates error state with blinking
1 blink (repeated) indication of the "TEST" mode - the EA is put to the position according
to the signal in the "TEST" menu (at connecting the 66 and 86/87
terminals)
2 blinks (repeating after short pause) missing of control signal - the EA is put to the position according to the
signal in the "TEST" menu
4 blinks (repeating after short pause) torque switches activity indication (the EA switched-off with the torque
switches in a mid-position)
5 blinks (repeating after short pause) failure of the feedback transmitter - the EA is put to the position
according to the signal in the "TEST" menu
7 blinks (repeating after short pause) control signal (current at range 4-20mA less than 4mA (3.5mA).
