Function description
][Funktionen_Zweihand
 The two-hand control relay must be
activated by simultaneously press-
ing two buttons within 500 ms. If
one or both of the buttons are re-
leased, the unit interrupts the con-
trol command for the hazardous
movement.
 Reactivation: The output relays will
not re-energise until both operator
elements have been released and
then re-operated simultaneously.

 POWER: Supply voltage
 Button 1/Button 2: Input circuits
S11, S21
 Feedback loop: Feedback loop Y1-
Y2
 Output safe: Safety outputs 13-14,
23-24
 Output aux: Auxiliary contacts 31-
32
 t

: Recovery time after power on
 t

Please note:
 Information given in the “Technical
details” must be followed.
 Outputs 13-14, 23-24 are safety
contacts, output 31-32 is an auxilia-
ry contact (e.g. for display).
 Do not use auxiliary contact 31-
32 for safety circuits!
 To prevent contact welding, a fuse
should be connected before the
output contacts (see technical de-
tails).
 Calculation of the max. cable runs
I
max
in the input circuit:
R
lmax
= max. overall cable resist-
ance (see technical details)
R
l
/ km = cable resistance/km
 Use copper wire that can withstand
60/75 °C.
 Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.
