Unit features
}Muting lamp in accordance with EN 61496
}2 semiconductor outputs for function monitoring
}Scope of supply:
– Muting lamp including bulb
– Mounting bracket
– 2 screws
Function description
In muting mode, the operator must be made aware of the hazard that results from the sus-
pension of the safety function. The muting lamp is designed for this purpose. It illuminates
as soon as muting mode is started.
Two semiconductor outputs enable the function of the lamp to be monitored.
}Normal mode:
If the lamp is not operated, both outputs are low. If the lamp is operated and illuminated
(muting mode active), both outputs are high.
}Error during operation
If an error occurs or the lamp is faulty, at least one of the two output signals changes to
low.
Recommendation: To increase the availability of the plant, you can use a second muting
lamp. If one of the muting lamps fails (e. g. faulty bulb), the second muting lamp takes over
its function.

Installation and wiring
The cover must be taken off and the bulb removed for installation and wiring:
}Turn the cover to the right and pull it off upwards.
}While applying slight downward pressure, rotate the bulb by approx. 90° to the right and
pull it out.
Fig.: Take off the cover and remove the bulb
Wiring
CAUTION!
Wire the lamp when it is isolated from the power supply.
}Perforate the stuffing box using a screwdriver.
}Connect the supply voltage and the input signal that signals muting mode to the 3-pole
terminal.
}Depending on the category required, connect one or both semiconductor outputs to an
evaluation device.

Installation
CAUTION!
The muting lamp must be mounted upright.
}Install the base directly on a horizontal surface or on the fastening bracket using the two
screws supplied.
}Install the fastening bracket with the base on a vertical surface.
Fig.: Installation
}Refit the bulb and the cover. To ensure that no dirt enters the housing, the cover must be
securely locked to the base. Rotate the cover to the left until the lug on the cover en-
gages behind the lug on the base.
Fig.: Fit the bulb and lock the cover
If it is necessary to open the cover again, e.g. to replace the bulb, press down the strip un-
derneath the lug using a screwdriver. In this way the cover is unlocked and can be opened
by rotating.
