Terminal board of the 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).
Note:
Signal READY is brought out as contact of the relay on the terminal board. If the state ERROR or
WARNING is not detected (setting can be made of what is to be evaluated as error or warning), the contact is
closed; 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.
In DMS2 setting program we will restore the parameters from backup by pressing button "Restore".
