6.3 Gripper Pulse Mode
The best way of handling two copies in a Gripper, and cut-edge first delivery is to attach a
Gripper pulse to the speed sensor input. This is a signal which is normally available in
Gripper conveyors. Normally it is a proximity switch which senses each Gripper. This pulse
can be connected to the input on the DENEX Gripper LED as described in chapter 4.
With DIP-switches the Gripper Pulse Mode is selected.
In this mode, the output signal is activated when a copy edge comes, and it stays on until
the Gripper pulse/proximity switch changes status, see figure 6.3.1.
There are four alternative setting depending on desired polarity of DENEX Gripper LED
Output Pulse and Speed Sensor Input.
During the time that the output pulse is active, no extra pulses can be sent. This will
simulate a mechanical switch (Ferag-finger), since the pulse stays on for a specific
distance instead of a fixed time, but without the bouncing that mechanical sensors
produce.
By making an adjustable bracket where either the sensor or the proximity switch for the
Gripper pulse can be adjusted sideways, a Blocking Zone of any size can be chosen.
