Variable Speed Gear Units and Accessories
Changing
switching
interval X
If no circuit state change occurs at the voltage encoder with rotating shaft of the variable
speed gear unit operating at switching interval X, then the switching interval can be
changed. The circuit state change is indicated by the yellow LED on the front side of the
speed monitor (page 24).
1. If the
yellow LED
on the speed monitor is
constantly lit
, turn the voltage encoder a
half turn counterclockwise at a time and check to see if it is functioning.
2. If the
yellow LED
on the speed monitor is
not lit
, turn the voltage encoder
at most two
times
(for D16/26) or
six times
(for D36/46) by 90 degrees in clockwise direction.
3. If a circuit change still does not occur, check the voltage supply of the voltage
encoder using the evaluation electronics (with WEX version).
Contactless
digital remote
speed indicator
The contactless digital remote speed indicator, which is included in the scope of delivery
with the WEXA version, is connected to the pulse output of the speed monitor type
KFU8-UFC-Ex1.D by P Fuchs.
Do not screw the voltage encoder more than half a turn (for D16/26) or 1.5 turns
(for D36/46) into the mounting hole because the voltage encoder would be
destroyed by a collision with the rotating recesses of the friction ring carrier.
Observe the applicable wiring regulations for potentially explosive areas during
the electrical installation of optional equipment.
