General Notes
The product hereby described was developed to perform safety functions
as a part of a whole installation or machine. A complete safety system
normally includes sensors, evaluation units, signals and logical modules
for safe disconnections. The manufacturer of the installation or machine
is responsible for ensuring proper functioning of the whole system. DOLD
cannot guarantee all the specifications of an installation or machine that
was not designed by DOLD. The total concept of the control system into
which the device is integrated must be validated by the user. DOLD also
takes over no liability for recommendations which are given or implied in
the following description. The following description implies no modification
of the general DOLD terms of delivery, warranty or liability claims.
Designated Use
The frequency monitor UH 6937 serves the safety-related detection resp.
monitoring of overfrequency and underfrequency or the monitoring of a set
frequency window. Furthermore, the frequency monitor serves the phase
sequence detection and thus the monitoring of the rotary direction of
motors with 3-phase alternating currents. The measuring of the frequency
and phase sequence is made via the frequency measuring inputs E1a,
E1b, E2L, E2H, E3L and E3H. The frequency limits, the monitoring
function, the rotary direction and further parameters can be set by the
user via the front display and adapted to a variety of applications.
When used in accordance with its intended purpose and following these
operating instructions, this device presents no known residual risks.
Nonobservance may lead to personal injuries and damages to property.
Safety Notes
Risk of electrocution!
Danger to life or risk of serious injuries.
WARNING
• Disconnect the system and device from the power supply and ensure
they remain disconnected during electrical installation.
• The device may only be used for the applications described in the
mutually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• Note the VDE and local regulations, particularly those related to protective
measures.
Risk of fire or other thermal hazards!
Danger to life, risk of serious injuries or property damage.
WARNING
• The device may only be used for the applications described in the mutually
applicable operating instructions / data sheet. The notes in the respective
documentation must be heeded. The permissible ambient conditions
must be observed. In particular, the current limit curve must be heeded.
• The device may only be installed and put into operation by experts who
are familiar with this technical documentation and the applicable health
and safety and accident prevention regulations.
Functional error!
Danger to life, risk of serious injuries or property damage.
WARNING
• The device may only be used for the applications described in the
mutually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• The device may only be installed and put into operation by experts who
are familiar with this technical documentation and the applicable health
and safety and accident prevention regulations.
• The unit should be panel mounted in an enclosure rated at IP 54 or
superior. Dust and dampness may lead to malfunction.
Installation fault!
Danger to life, risk of serious injuries or property damage.
WARNING
• Make sure of sufficient protection circuitry at all output contacts for
capacitive and inductive loads.
!
Attention!
• The safety functions used (frequency monitoring and/or direction of
rotation monitoring) must be checked and triggered during commissioning.
• Any continuously repeated switching over of the speed modus
(always immediately after the expiry of the switchover time period) can
lead to the situation, that the equipment starts to function similarly as in
the 'Muting Mode' (i.e. the speed monitoring function is overridden and
the output relays remain permanently on).
• If the duration of the rotary motion is always shorter than the set discrepancy
time, it is necessary to check whether the measuring frequencies are
properly detected after 24 h resp. before a system is restarted.
• The adjusted parameters must be filled in the „Formular for documentation
of the setting parameters".
• Opening the device or implementing unauthorized changes voids any
warranty
