Automatic on / off
In „automatic“-mode the Wedge barrier moves automatically into the blocking position after
expiration of the time pre-set T10, provided that the light barriers are not interrupted and the
induction loops are not occupied.
The function of control switches “lower”, “stop”, “raise”, induction loops and light barriers is always
independent of the automatic function.
Pulse contact control
If the controller is operated while the Wedge is in an intermediate position, the barrier moves into
the lowered position.
If the controller is operated while the Wedge is in the final position, the barrier moves into the
opposite direction.
Any operation of the controller stops the movement of the Wedge.
If the controller is operated several times during the movement of the Wedge, the following
switching sequence results: “raise“, “stop“ , “lower“, “stop“, “open“, etc.
Proximity switches “lowered” (S6) / “raised” (S7)
The limit switches indicates the final positions of the Wedge.
If the limit switch for the preselected direction is occupied, the respective valve, as well as during
raising the motor will be switched off after expiration of a pre-set time of one second.
Induction loop 1 A2.1 (close / safety) / Induction loop 2 A2.2 (safety)
After passing of both induction loops, and expiration of pre-set time T4, the Wedge raises.
If one of the loops is occupied again while the Wedge is raising, the barrier stops and lowers again.
It raises again if the loops are not occupied and after expiration of the pre-set time.
The function emergency raise will ignore an occupied induction loop.
Light barrier
After interruption of the light beam, the Wedge can’t be raised. If the light beam is interrupted while
the Wedge is raising, the barrier stops and moves back into the completely lowered position.
In „automatic“-mode the Wedge closes again after removal of the disturbance and expiration of the
pre-set time T4. In “manual”-mode a command raise or lower is expected.
If the light beam is not interrupted, the Wedge raises (if the loops are not occupied) after expiration
of the pre-set time T4.
The function “emergency raise” will ignore an interrupted light barrier.
Malfunction
Too high oil temperature, disengaged motor circuit switch, seized run time excess as well as a too
low oil level are faults. If an error occurs, the exit “disturbance” is set immediately.
An emergency stroke of the Wedge into the raised position is possible via the entrance
“emergency raise” except the motor circuit switch is disengaged.
Further electrically controlled movements of the Wedge are afterwards no longer possible! If
necessary, the Wedge can be lowered manually by opening the ball cock valve (5) positioned
directly at the aggregate.
