Disposal
Electronic Components
Products which have not been disassembled can be disposed of
under Code No. 160214 (mixed materials) or components under
Code No. 160216 (Code No. acc. 200/532/EC), or can be disposed
of by a certified disposal firm.
Malfunction
Possible Causes
Measures
Brake does not release
No supply voltage available
Check voltage on input terminal
Brake line interrupted
Check brake supply line (check passage)
Line voltage drop on long line
Check the brake voltage
Air gap not okay
Open and clean the brake, check the air gap. If
possible, adjust the air gap.
No signal
Brake is not permitted
Use released brake
Brake is worn
Open and clean the brake, check the air gap;
replace the brake if necessary
Incorrect input voltage polarity
Check input voltage and rotate if necessary
Error (continuous
signal)
Brake release is not recognised
Check: Brake is not permitted
Incorrect monitoring module (brake nominal voltage)
Brake drop-out is not detected
Brake is not permitted
Check the function of the monitoring module
Break voltage drop
Check network stability and reinstate it
Unit temperature over 90 °C
Check ambient temperature and, if necessary,
improve the cooling.
Warning
Coil temperature of the brake too high
Check effective coil power, ext. Temperature, friction
power
Wear
Replace rotor
Supply voltage too low
Check and, if necessary, increase supply/output
voltage of the monitoring module; check line length
Clock frequency or P
N
(coil nominal capaci-
ty) too high
Lower clock frequency or P
N
(coil nominal capacity)
Unit temperature over 85 °C
Check ambient temperature. Check clock frequency
and P
N
.
Guidelines on the WEEE Directive 2012 / 96 / EU
Avoidance of waste from electrical and electronic devices
and the reduction of such waste through recycling.
Our electromagnetic products (ROBA-stop
®
/ ROBA-quick
®
/ ROBATIC
®
clutches) as well as the components required for
control and monitoring (rectifier / brake-checker) and the
DC motors (tendo
®
-PM) are frequently used in electrical and
electronic devices within the appropriate area of application
of WEEE, independent of the applicable product categories.
The stated products do not fall within the area of application
of this Directive.
They have been classified as electromagnetic / electronic
components (VDE 0580) or as electronic equipment (EN
50178), and have been determined for installation in devices
for "use in accordance with the intended purpose". Only
products which are to be viewed as devices in terms of the
Directive and not as parts or components are subject to
registration obligations.
