Lim -rotary switch is set to the TEST position
When the Lim rotary switch is set to the TEST position, automatic control unit OMD200 or OMD300
enters the test sequence. While entering the test sequence OMD200 or OMD300 blinks all LEDs twice to
give the information that the LEDs are functioning.
In the TEST position it is possible to simulate switching and back switching sequences step-by-step by
pressing the AUTO key. The user can interrupt the simulation at any place and return to normal use of
the device. More information, see Section 6.3.
NOTE:
In the TEST sequence the power circuit is switched on!
NOTE:
After testing the user must ensure that the device is not left in the TEST position by
accident.
NOTE:
I
TEST sequence is interrupted for example because of power failure, it is continued from
that same situation where it was when interrupted.
