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.
