Before setting the parameters, limit switches of the actuator must be connected and adjusted and the position
transmitter must be set. If moment switches are used as limit switches it is necessary to ensure that the actuator or
the valve can produce required tripping moment.
The parameters of the regulator cannot be set as long as the actuator shaft is in one of its extreme positions
and if it is switched off by the limit switch; auto-calibration would not be performed and the regulator would report
an error. Therefore, before setting the parameters, the actuator must be adjusted - e.g. by the hand wheel - so that
the output shaft is in an intermediate position
(i.e. in a position when the actuator is normally not switched off by
any of the limit switches).
Setting of parameters
In setting the parameters according to these instructions, change over to the setting regime by keeping
the push-button SW1 pressed until the yellow diode D3 on the regulator is lit on (about 2 s). Then, release
the push-button SW1 and parameters on the regulator can be set (list through the menu depicted by the yellow
diode D3 by short pressing SW1, set the parameters depicted by the red diode D4 by short pressing the push-
button SW1 ) - see the following Menu 1 - Menu 5. If, by pressing the push-button SW2, the latest value of
the parameter in the particular menu is selected another pressing of the push-button SW2 will bring you back
again to the first value of this parameter. In this way you can select values of parameters in cycles according to
the list for the given parameter. After particular value of the parameter has been selected, press the push-
button
SW1 shortly. The selected value of the parameter is acknowledged and the following menu is chosen.
If, by gradual pressing the push-button SW1, the MENU 5 is reached the following short pressing of the push-
button SW1 will return you again to the MENU 1 (another pressing to MENU 2, etc.]. In this way, the set
parameters can be checked and changed during setting).
Always when red diode
D4 is lit on - during regulation, auto-calibration and in setting parameters - the contact KOK
(terminals J1-4, J1-50) is closed.
The diodes D3 and D4 give a signal by the number of flickering.
Menu 1: Setting control signal
D 3 (yellow)
D 4 (red) 0 – 20 mA
4 – 20 mA
0 – 10 V
Menu 2: Setting response to signal Test and in case of failure
D 3 (yellow)
D 4 (red) opens
closes
no response
Menu 3: Setting mirroring (ascending/descending characteristics)
D 3 (yellow)
D 4 (red) higher signal - CLOSED (descending characteristics - mirroring)
higher signal - OPEN (ascending characteristics - no mirroring)
Menu 4: Setting insensitivity of regulator
D 3 (yellow)
D 4 (red) 1 %
2 %
.... ....
10 %
Menu 5: Setting way of regulation
D 3 (yellow)
D 4 (red) narrow to moment
narrow to position
broad to moment
broad to position
