Profile-heating (optional)
Condensation on the contact surface of the ProfiDAT
®
profile can lead to insulation faults, as well as increasing oxidation of the rail
and wear of the carbon brushes. The conductor rail heating is designed to prevent condensation, hoarfrost or ice from forming around
the contact surface.
To this end, the ProfiDAT
®
profile is temperature controlled using an optional heating cable starting at a temperature near the dew
point or the point of formation of frost and ice. The trace-heating cable is laid in the cavity of the profile and is supplied as a conductive
loop with external auxiliary power.
The heating power required depends on a number of parameters. It must be taken into consideration that whether ice forms on a
profile or not depends on the installation situation of the profile and its environment,
Where a profile is exposed to wind, wind-chill effects can cause ice to form even when the temperature is still above 0°C.
The profile-heating controller has temperature and dew-point sensors. The profile heating is switched on if the temperature falls
below a certain value and reaches the dew point.
Electrical hazards and sources of danger
DANGER!
Risk of death by electrical shock!
When working on these components, death or injury may result from electrical shock, burns,
or electrical arcs, because they are electrically live:
Conductor rails and current collectors, cables and connections, servomotors, switching
cabinets and control systems.
Before entering the danger zone and working on these components:
Disconnect the system from the power at the main switch.
If there is no main switch, disconnect the energy source from the system according to
the instructions of the system manufacturer.
Secure the system against being switched on again.
Confirm that the power has been disconnected.
Ground and short-circuit parts of the system disconnected from power.
Cover or block off adjacent energized components,
Before each start-up, test the insulation resistance according to locally applicable
technical standards, directives and laws.
WARNING!
Risk of fire!
Overloaded cables are a fire risk!
Before commissioning, test the product in accordance with the manufacturer’s
checklist.
Only have testing carried out by qualified technicians who are familiar with both the
product and the regulations concerning workplace safety and accident prevention.
