Set-Up; Start-Up; Installation; Operation - Kendrion EEX Series Operating Instructions Manual

8.2.1 Set-up

Requirements in terms of the permissible number of switching operations per hour and the maximum switching
work per switching operation (see Fig. 32/1) specified in the technical specifications must be strictly observed
during the set-up of machines and plant (jog mode). Failure to observe these instructions may irreversibly
diminish the braking effect and cause malfunctions. Normal operating conditions are those specified by DIN
VDE 0580. The protection rating conforms to EN 60529. In case of deviations, special measures must be taken
after prior consultation with the manufacturer. If vertical brake operation is envisaged, any special requirements
must be agreed with the manufacturer. Bear in mind that the friction disc may freeze if ambient temperatures
fall below 5°C or if the brake remains unpowered for prolonged periods of time. In this case, special precautions
must be taken after consultation with the manufacturer.

8.2.2 Start-up

The brakes must not be put into operation when:
power supply cables/wires or connections are damaged.
•
the solenoid housing or coil sheath is damaged.
•
other defects are suspected.
•

8.2.3 Installation

The voltage level and voltage type specified on the rating plate must be strictly observed when connecting the
brakes described in these operating instructions. Sufficient heat dissipation must be ensured when the brake
is fitted to or incorporated into other equipment. Adequate precautions must be taken to avoid overvoltage
during disconnection or voltage peaks. The magnetic field of the products may cause interference outside the
brake or even feedback to the brake in case of adverse installation conditions. Should you have queries
concerning mounting and fitting conditions, please contact the brake manufacturer and ask for clarification.
Adequate safety measures (DIN 31000; DIN VDE 0100-420) must be taken by the brake user to avoid hazards
to persons and animals or damage to equipment caused by:
direct or indirect effects of electromagnetic fields,
•
heated components,
•
• mobile parts.

8.2.4 Operation

Ensure that live components such as plug contacts or the field coil are not exposed to water. The brake cable
connections must not be crushed, squeezed or exposed to mechanical loads. Make absolutely sure that the
friction surfaces of the friction elements are not contaminated with grease, oil or other fluids to avoid substantial
torque reduction. Bear in mind that the original torque cannot be restored even if the friction surfaces are
cleaned after contact with fluids. The gradual brake wear and the resulting torque reduction of spring-applied
brakes must be taken into consideration during set-up of the machine/equipment. Due to the diverse ambient
conditions in which the brakes may be used, always check that the brake is in perfect working order before
start-up. Torque reductions cannot be ruled out if the brake is used for applications where only minimum friction
work is required. In such cases, the user should ensure that the brake occasionally performs sufficient friction
work. Operation of the brake as pure holding brake without friction work is only allowed after prior consultation
with the manufacturer. If brakes equipped with hand release are used, the handle of the hand release must
only be moved up to the release position in order to avoid deformation or breaks.
