Fiessler AKAS-3PM - Input;Output Signals and Status Display

Instead of using a rear protective metal grid, a safety light grid with equivalent switching outputs, e.g.
type Fiessler ULVT / TLVT or ULCT / TLCT as shown in wiring diagram 6/p.33 is possible.
As alternative, the connection of a light grid with antivalent switching outputs is also possible, like p.e. the
Fiessler light grid EU2K 500/2. Wiring Diagram 7/p.33 shows the connection of the Fiessler light grid
EU2K 500/2 as a rear safeguard. In this case, the switches of the lateral protective grids must have anti-
valent switching contacts (1 normally closed and 1 normally open contact each) and the operating mode
with antivalent switching protective door circuits must be selected. In this case, the connector 1 at the
transmitter of the EU2K 500/2 must be wired to the output S_EU2K of the AKAS®.
The lateral protective grids are not monitored. Every switching-over of the selector, the reset buttomn
must be activated for the Emergency-OFF circuits and the circuits of the lateralprotective doors.

Only to use the operation modes D...D... or F...F...!
These modes activates Start interlock for the rear safety lightgrid! (see chapter 6.5.2)
If the connected lightguard does not detect all possible cross circuit and short circuit on the out-
puts OSSD 1 and OSSD2 you have to wire them in a way that no cross and short circuit is possible.
