1. General information
1.1 General safety instructions
Read these installation and operating instructions carefully before putting the brake into
operation. Consider these instructions as well as the drawings in the individual sections.
All work with and on the brake is to be carried out considering that "safety is top priority".
Switch the drive unit off before carrying out work on the brake.
Rotating parts (e.g. brake disc) must be secured by the operator against unintentional touching.
1.2 Special safety instructions
2. Configuration, mode of operation and standards
2.1 Function
The brake is a machine element with which accelerated masses can be safely slowed down. In
combination with a brake disc, you have a complete brake for the effective safeguarding of
machines and systems. Thanks to its universal design, it fulfils the following functions:
•
As a holding brake, it prevents a stationary shaft from starting unintentionally.
•
As a stopping brake, it brings a rotating shaft to a halt.
The brake force is generated by a spring (5) and the brake is released by means of an
electromagnet (1). If the friction blocks (2) are worn out, the holding or braking torque decreases
as the spring preload is reduced.
Max. Sound level during opening is 63
dB (measured according IEC 61672-
2 “Fast”, with max.
clamping force).
2.2 Identification
These installation and operating instructions are valid for:
•
the version DV 020 FEM, brake caliper attachment parallel to the brake disc.
•
the DV 020 FEM with left-mounted electromagnet as shown in Fig. 2.1, for mounting on a 12.5
mm thick brake disc.
•
the DV 020 FEM with right-mounted electromagnet.
•
various types of brake-pads, and special brake pad materials.
•
with manual spring force adjustment and special frame.
•
the standard design, the cCSAus design and with proximity switch.
There is a type plate on the brake with a 16-digit part number. The exact design of the brake is
defined by this article number only.
As well as these instructions, please also consider the catalogue data for the brake at
www.ringspann.com and the drawings in the individual sections.
Life-threatening danger!
When assembling, operating and maintaining the brake it is to be ensured
that the entire drive train is secured against being switched on
unintentionally. Moving parts can cause severe injury. Rotating parts (e.g.
brake disc) must be secured by the operator against unintentional touching.
