Two-Hand Control (switch 1 in position 5)

4 pairs of 2-hand buttons Typ III A or 2 pairs of 2-hand buttons Typ III C
according to EN ISO 13851 can be connected in this function. The number
of connected button pairs has to be selected on the device.
K1 and K2 can only be activated, if 3 conditions are fulfilled:
- First all button pairs have to be in initial position.
- Both buttons of 1 pair have to be pressed within 0.5 sec.
- All connected pairs have to be operated within 15 s.
If changeover contacts are used in the 2-hand buttons the switchover time
has to be less then 50 ms. If it is longer the outputs K1 and K2 are switched
off and the unit gives failure code 7. This failure is stored and can only be
reset by disconnecting the auxiliary supply.

Set-Up Instructions

The device has to be connected as shown in the application examples.
When connecting the push-buttons in parallel or in series the safe function
of the relay is disabled. The buttons must be designed and installed in
a way, that it is not possible to manipulate or to operate them without
intention.
The distance between push buttons and dangerous area must be chosen
in a way that it is not possible to reach the dangerous area after release of
one button before the dangerous movement comes to standstill.
The safety distance "S" is calculated with the following formula:
S = V x T + C
a) moving speed of person V = 1 600 mm/s
b) stopping time of the machine T (s)
c) Additional safety distance C = 250 mm
If the risc of accessing the dangerous area is prohibited while the push
buttons are pressed e.g. by covering the buttons, C can be 0. The minimum
distance has to be in this case 100 mm. See also EN ISO 13851.
