Intended Use
ROBA
®
-brake-checker products have been developed,
manufactured and tested as electronic equipment in
compliance with the DIN EN 50178 standard and in
accordance with the EU Low Voltage Directive. During
installation, operation and maintenance of the product, the
requirements for the standard must be observed. ROBA
®
-
brake-checker products are for use in machines, systems
and devices and must only be used in the situations for
which they are ordered and confirmed. The products are
designed for installation into electrical control cabinets and
terminal boxes. Using them for any other purpose is not
allowed.
EMC-compatible Installation
• Avoid antennae effects: Keep the supply
cables as short as possible; do not form
rings or loops with the cables!
• Mount good earth connections onto the
metal body of the brake.
• Lay control cables (total length <30 m)
separately from power cables or from
strongly pulsating supply cables!
Continuous drop-out recognition
The continuous drop-out recognition can detect the follow-
ing situation and signal it via the outputs:
Brake is energised --> Undesired movement of the armature
disk for closing the brake (drop-out of the armature disk).
Changes of the output signals:
Control terminal 14: OUT (0.99 × U
I
)
--> 0 VDC
Control terminal 13: ERR (0.99 × U
I
)
--> 0 VDC
Possible Causes
• Excessive temperature
• Marginal dimensioning
• Mechanical influences
Device Fuses
Installation of a device fuse into the supply voltage line of the
ROBA
®
-brake-checker monitoring module.
Short-circuits or earth short-circuits can lead to ROBA
®
-
brake-checkermonitoring module failures. After fuse
elements have reacted to a malfunction, the ROBA
®
-brake-
checker monitoring module must be checked for functional
and operational safety (overexcitation voltage, switch-off
voltage, response delay time, holding voltage). The same
also applies after the magnetic coil of the brake has failed.
