The PIT js2/PIT js2 bc command device consists of a plastic housing with 3 pushbuttons
and/or 2 pushbuttons and a blind plug.

}
2 pushbuttons (ACT1 and ACT2) for the two-hand function (N/C / N/O contact, respect-
ively)
}
PIT js2: 1 pushbutton (RESET) for the reset function (N/O)
}
PIT js2 bc: 1 blind plug
}
The contacts are connected by a coiled cable with an open end.
Function description
An enabling signal is generated in conjunction with a two-hand monitoring module by simul-
taneously pressing the ACT1 and ACT2 pushbuttons. This overrides the safety function of
the movable guards. Authorised operating personnel then can enter the danger zone to
monitor work processes.
Releasing one or both pushbuttons ACT1 and ACT2 will interrupt the enabling signal. A
subsequent enabling signal can only be generated once both pushbuttons have been re-
leased. On PIT js2, the Reset pushbutton can additionally be incorporated into the control
system to generate a subsequent enabling signal.
Wiring
}
Connect the ACT1 and ACT2 buttons to the control system in such a way that both push-
buttons must be actuated in order to generate an enabling signal.
}
PIT js2: You can connect the Reset button to the control system such that, after releasing
one or both pushbuttons ACT1 and ACT2, a subsequent enabling signal can only be gen-
erated once the Reset pushbutton has been actuated.
