is present at semiconductor output Y35 (both muting lamps defective). The "ML Fault" LED
is lit. If the light guards (ESPE) are interrupted when the muting lamps are defective, then
safety contacts 13-14/23-24/33-34 are opened redundantly, auxiliary contact 41-42 is
closed. Status indicators "Output", "OSSD CH.1" and "OSSD CH.2" go out.
NOTICE
Only use muting lamps that switch themselves off if there is a defect.
Installation
}
The unit should be installed in a control cabinet with a protection type of at least IP54.
}
Use the notch on the rear of the unit to attach it to a DIN rail (35 mm).
}
When installed vertically: Secure the unit by using a fixing element (e.g. retaining
bracket or end angle).
}
When installing the light guards (muting sensors, ESPE), it is essential that the respect-
ive standards and regulations are observed. If you are using reflective light barriers
(parallel muting with 2 muting sensors), the light beams must cross within the danger
zone.
}
The start button has to be installed in such a way that the operator can see into the
danger zone when operating the start button.
Wiring
Please note:
}
Information given in the "
Technical details [
21]
" must be followed.
}
Outputs 13-14, 23-24, 33-34 are safety contacts; output 41-42 is an auxiliary contact
(e.g. for display).
}
Auxiliary contact 41-42 should
not
be used for safety circuits!
}
Semiconductor outputs should
not
be used for safety circuits!
}
Delivery status: S51-S52/S61-S62/Y1-Y2/S31-S32 are linked
}
To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [
21]
).

}
Use copper wire that can withstand 60/75 °C.
}
Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
}
Do not switch low currents using contacts that have been used previously with high cur-
rents.
}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
