Terminal board of actuator with electronics DMS2ED.
If the actuator is of the single-phase version the power supply is connected only to terminals
PE, N, U.
The terminals
V, W
remain non-connected. If the actuator is of the version “Replacement of electric-mechanical board” with three-phase
electric motor without power relays, the electric motor is connected to a separate terminal board (not shown here).
Record of position CLOSED:
– In the required position, press push-button Z in the program and confirm the approved record.
Record of position OPEN:
– In the required position, press push-button O in the program and confirm the approved record.
The recorded values are confirmed by pressing push-button START in program DMS2. For the actuator in version
CONTROL, change over the actuator to remote control and, by pressing push-button START, start the autocalibration.
By short starting of the motor in both directions, the actuator measures inertia and changes over to the regulating
regime. Information on the course of autocalibration is signalized next to push-button START. The autocalibration
cannot be started in case the torque relay is switched off. The torque should be left manually.
Other parameters
Check and, if necessary, change other parameters:
Control signal 4 – 20 mA, 20 – 4 mA, 0 – 20 mA, 20 – 0 mA
Insensitivity 1 – 10 %
Function in case of error open, close, stop, to position
Time of torque blocking in end-limit positions 0 – 20 s
Position of torque blocking in end-limit positions 1 – 10 %
Output of position signal 4 – 20 mA, 20 – 4 mA
Function READY combined error
Note: Signal READY is brought out as contact of the relay on the terminal board. If the state ERROR or WAR-
NING is not detected (setting can be made of what is to be evaluated as error or warning), the contact is clo-
sed; in case of error, warning, or if feeding of electronics is interrupted, the contact is opened. The state of the
relay READY is indicated by the LED diode on the source board.
AUTODIAGNOSTICS
DMS2.ED performs continuously its diagnostics and, if a problem is detected, it reports warning or error. The warning
or error is signalized by LED of the display and, possibly, by relay Ready. The warning has no effect on operation of the
system, the error stops the actuator.
Assigning or switching off of warnings and errors is set in window “Warning and error” of the setting program (it is
opened by clicking one of parameters Warning 1 – 4 or Error 1 – 4 in window “Parameters”).
The error or warning are reported by opening the relay READY and by blinking of the red LED diode on the control
unit. Particular error is specified by program DMS2 or on the display.
RESTORING PARAMETERS FROM BACKUP
With the feeding switched off, press push-buttons O and C at the same time. Then, switch on feeding and wait until
red and yellow LED diodes light on. The backup parameters are read.
