Muting lamps
The muting controller PMUT X1P is designed for use with one or two muting lamps. As
soon as the inputs of the light guard are muted, the Muting lamp ML1 will light. The PMUT
X1P monitors the connected muting lamps during the muting cycle. If muting lamp ML1 is
defective (e.g. coiled filament broken or lamp switched off), then the PMUT X1P automatic-
ally switches to muting lamp ML2. A high signal is present at semiconductor output Y34
(muting lamp 1 defective). If muting lamp ML2 is defective or is not connected, a high signal
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.
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.
} Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele-
ment (e.g. retaining bracket or an 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 [ 512]" 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 [ 512]).
