1. General remarks
1.1 General safety instructions
Please read these installation and operating instructions carefully before installing and operating
the brake. Please refer also to the drawings in the various sections. Safety must be given the
highest priority during all work performed on the brake. Switch off the drive unit before performing
work on the brake. Rotating components (e.g. brake disc) must be secured by the operator to
prevent accidental contact.
1.2 Special safety instructions
Danger to life and limb!
It is essential to secure the entire drive train against inadvertent starts dur-
ing brake installation and maintenance. Rotating components can cause
severe injuries. Therefore, rotating components (e.g. brake disc) must be
secured by the operator to prevent accidental contact.
2. Function, Marking, Technical details and Standards
2.1 Function, Operating Principle
The brakes of type EV an EH are machine components, used for the purpose of braking acceler-
ated masses safely and reliably. The combination of brake and brake disc provides a complete
brake unit capable of securing machines and equipment system effectively. Thanks to its univer-
sal design, it can perform the following functions:
•As a holding or parking brake, it prevents the unintended start of a stationary shaft.
•As a stopping brake, it brings a rotating shaft to a complete standstill.
Braking force is generated by spring force (46), the brake is released electromagnetically (2). If
the lining of the friction blocks (1) wears out, the holding or braking torque is reduced because the
spring preload is reduced.
2.2 Marking
These installation and operating instructions apply to:
•the types EV/EH 018/024/028/038 FEM, each with two separate voltage ranges 240V (220 …
240VAC) and 480V (380 … 480VAC).
•installation on horizontal brake discs and vertical brake discs in combination with horizontal
shafts
•for models with and without switches
•for different brake pad material and for brake pads with signal cables.
•with cable bushing (cCSAus type) and plug as connection for the supply voltage

3. Proper use / specified purpose
The brake may only be connected with the voltage marked on the nameplate and corresponding
to the technical details. 240VAC = 220 … 240 VAC, single phase
480VAC = 380 … 480 VAC, single phase
With 50 Hz or 60 Hz (no adjustment necessary), single phase and corresponding to the technical
details. The electrical connection see chapter 8.4.
The brake is designed for use as a holding/parking brake and/or stopping brake.
Other uses are improper and incompatible with the specified purpose. RINGSPANN assumes no
liability for damages resulting from improper use. The risk is assumed by the user alone.
4. Improper use
Operating the brake with other supply voltage as specified on the nameplate is prohibited.
To switch the brake without brake disc is only allowed if the assembly locking nut Pos. 25 in Fig.
5.1 remains on the brake and is loosened not more than 4 mm.
Repeated switching without brake disc and without assembly locking nut can damage the brake.
Unauthorized constructive modifications of the brake are similarly prohibited. If the grub screw
pos. 44 is provided with sealing wax at the factory, the clamping force on the brake must not be
adjusted by the customer!
To protect the brake electronics, the installation of surge protectors is mandatory to con-
trol the overvoltage. These surge protectors must be connected between the customer's
switching relay and the brake electronics.
It is not allowed to mount the brake with the brake body looking downwards:
For damages caused by switching the brake without brake disc or unauthorized constructive
modifications RINGSPANN assumes no liability for damages resulting from improper use. The
risk is assumed by the user alone.
Attention!
To switch the brake without brake disc is only allowed if the assembly locking nut
Pos. 25 in Fig. 5.1 remains on the brake and is loosened not more than 4 mm.

5. Condition upon delivery
The brake is tested prior to delivery. The braking force is adjusted to the maximum braking force.
The compression spring for the clamping force is fixed in the open position by the assembly lock-
ing nut Pos. 25 in Fig. 5.1, to assemble the brake to the disk without supply voltage.
For operation, the mounting lock nut must be removed and the exact air gap adjusted (s. section
8.3).

6. Handling and storage
The weight of the brake depends on the size, between 6,5kg and 50kg, see also chapter 2.3.
The brake is delivered with anti-corrosion protection and can be stored in an enclosed, dry space
for up to 12 months. It is important to prevent condensation from forming. Moist storage areas are
unsuitable.
7. Technical requirements for safe and reliable operation
Mounting the brake to stable, low-vibration machine components ensures low-screech, low-noise
braking.
To protect the brake electronics, the installation of surge protector is mandatory. These surge
protectors (per phase one) must be connected between the customer's switching relay and the
brake electronics. In this case, the surge protector of L1 and L2 is switched to N or PE in order to
derive mains disturbances. For 230 / 400V electric grids e.g., surge protection switch of the brand
"Bourns 1250-xS-230" can be used. In 480V mains surge protectors type "Bourns 1250-2S-400"
can be used.
8. Installation of the RINGSPANN brake
8.1 General instructions for assembly and installation
Before installing the brake, the brake disc must be cleaned with alcohol, e.g. ethyl or isopropyl
alcohol or a water-based surfactant solution (soapy water, etc.) and then rubbed dry with a clean
cloth.
When cleaning the brake disc with a thinner, acetone or a brake cleaning agent, it is important to
ensure that neither these cleaners nor any cleaner residues come in contact with the brake pads.
This is especially important in the case of brakes used only as parking brakes, as no dynamic
braking operations take place during which thinner residues would be rubbed off the brake disc.

Please note!
Oil and rust-proofing-agent residues reduced friction coefficient and thus dimin-
ish transmissible braking torque substantially!
8.2 Prior assembly and installation
Prior to installation, check to ensure that the mounting surface is even and planned run between
the brake disc and the mounting surface is within the tolerance range of 0.2 mm.
Check the axial movement of the brake disc. Axial movement must not exceed ± 0.2 mm.
Maximum permissible lateral brake disc wobble is 0.1 mm. Greater wobble may cause rattling
and shaking of the brake unit.
Attention!
Check to ensure that the brake disc rotates freely.
8.3 Adjust the brake to the brake disc thickness and mount the brake
The brake is delivered with a distance between the friction pads of 13,1 or 25,6 mm. You can ad-
just the distance between the friction pads with the setting screw Pos. 17 and Pos. 41 (see Fig.
8.1 or Fig. 8.2). The adjustment of the air gap between the friction pads and the brake disc is the
same as the adjustment of the brake disc thickness. You can adjust the air gap with the setting
screw Pos. 17 and Pos. 41 (see Fig. 8.1 or Fig. 8.2). The air gap between the friction pad and the
brake disc should be 0,3 mm. A bigger air gap reduces the braking force!
During installation, ensure that the brake pads are centred and in full contact with the surface of
the brake disc. For the distance X and Z see table 8.1 or 8.2. See also Fig. 8.1 or 8.2.
The brake can be hold in position with a lifting belt for the multiple installation positions.

8.4 Electrical Connection
Attention!
To protect the brake electronics, the installation of surge arresters is man-
datory to control the overvoltage. These surge arresters must be connected
between the customer's switching relay and the brake electronics.
Attention!
To protect the electronic against too fast switching, a security feature is inte-
grated in the electronic. The security feature locks the supply voltage and the
brake cannot be opened. After 40 s the electronic will pass the supply voltage
and after a further activation the brake will open.
Attention!
Only trained electrician are allowed to connect the brake with the supply
voltage. The trained electrician must be familiar with the relevant standards
(e.g. in Germany DIN VDE 0113).
Attention!
To use the brake the electronic Pos. 34 (included in the scope of delivery) is
mandatory. Do not connect the brake directly to the supply voltage. To switch the
brake without brake disk is only allowed if theassembly locking nut Pos. 25 in Fig.
5.1 remains on the brake and is loosened not more than 4 mm.
Attention!
For higher operating cycles (> 100 / h), the brake can heat up to 65 ° C.
The following rules must be observed:
a) It is not allowed to use coiled cables in the supply line. (e.g. cable drum, reserve cable loops or
the like)
b) For safe operation of the brake a sufficient grid quality is necessary. See also the standards of
grid quality.
c) Before replacing the electronic, check the coil of the solenoid to be shure that the coil is not
damaged. Please consult RINGSPANN.

8.5 Braking force adjustment
The entire surface of both brake pads must be in contact with the brake disc in order to achieve
the optimum braking effect. The brake pads must also be heated briefly to approx. 200°C. There-
fore, multiple brief braking operations under low spring force and rotating brake disc are required
to heat the brake pads.
Attention!
If the brake is used as parking brake, the brake torques specified are not met.
Reductions of up to 50% of the braking torques are possible.
Attention!
If the grub screw pos. 44 is provided with sealing wax at the factory, the clamp-
ing force on the brake must not be adjusted by the customer!
Attention!

The braking force is adjusted to the maximum braking force. If the braking force should be re-
duced, the clamping force can be reduced by reducing the pretension of the spring. Therefore
you have to loosen the threaded pin Pos. 44 of the spring compression nut Pos. 43. With the
spring compression nut you can adjust the distance S (see Fig. 8.5) according to the values in
table 8.4. If you reduce the clamping force the reaction time of the brake will increase. After the
adjustment, lock the spring compression nut with the threaded pin.

9. Commissioning
Attention!
To switch the brake without brake disc is only allowed if the assembly locking nut
Pos. 25 in Fig. 5.1 remains on the brake and is loosened not more than 4 mm.
Before commissioning you have to switch on the electric current (the solenoid holds the brake
open) and the assembly locking nut Pos. 25, Fig. 5.1 is to be removed.
The brake is now ready for operation.
10. Disassembling the brake
Danger to life and limb!
When disassembling the brake it is essential to ensure that the entire drive
train is secured against inadvertent activation. Rotating components can
cause severe injuries. Therefore, rotating components (e.g. brake discs)
must be secured against accidental contact. To prevent injuries to person-
nel, secure the brake with the aid of an assembly locking device.
Attention - SIZE 018 !!
Do not remove the cables between the brake and the electronics as long as the
brake is energized, this will destroy the magnet! (see figure 8.3).
Secure the open position with the assembly locking nut Pos. 25 and washer Pos. 26 in Fig. 5.1.
Therefore you have to switch on the electric current. After the brake is secured with the assembly
locking nut in open position switch off the electric current.
Attention!
Take care, that the electric supply cable is currentless.
Secure the brake for disassembly.
Remove the screws used to hold the brake in place. The brake can now removed from the
mounting surface.
11. Maintenance
11.1 General maintenance
Maintenance must be performed on the brake at intervals of 4 weeks up to once a year, depend-
ing upon the operating load.
Perform the following checks during every maintenance operation:
•Check brake pads for wear.
•Check the air gap between the brake pad and the brake disk.
•Check the bolt connection between the brake pad and the machine component as well as the
bolt connections for the retaining plates for tightness.
•Check the electric supply cables (sight check)

11.2 Brake pad adjustment, permissable brake pad wear and brake pad replacement
Danger to life and limb!
Brake pads may be replaced only when the equipment system and/or the work-
ing machine is at a complete standstill!
Attention!
Brake pads must not be worn to a residual thickness (mounting plate thickness
plus remaining pad material). Brake pads must always be replaced in pairs.
Only original RINGSPANN brake pads may be used.
Brake pad wear adjustment:
To counter brake pad wear you can adjust the distance between brake pad and brake disc with
set screws Pos. 41 and Pos. 17 (see Fig. 8.1 or 8.2). Therefore you have to switch on the electric
current and screw on the assembly locking nut Pos. 25 in Fig. 5.1. Screw on the assembly lock-
ing nut without tightening torque, only with hands.The gap between brake disc and brake pad on
each side should be 0,3 mm. The maximum allowable distance between brake disk and brake
pad without adjustment is 0,6mm. A greater gap will reduce braking force up to a complete loss of
braking force.
A greater gap will reduce braking force. Consider the maximum permissible wear of the brake
pads (see table 11.1).
After the adjustment of the gap between brake disc and brake pad, lock the set screw Pos. 41
and Pos. 17 with the locking nut Pos. 16 and Pos. 40 (see Fig. 8.1 or 8.2).
Remove the assembly locking nut Pos. 25, Fig. 5.1 The brake is now ready for operation again.
Attention!
The gap between brake disc and brake pad on each side should be 0,3 mm. A
greater gap will reduce braking force. The maximum allowable distance between
brake disk and brake pad without adjustment is 0,5mm (size 018 = 0,3mm). A
greater gap will reduce braking force up to a complete loss of braking force. Con-
sider the maximum permissible wear of the brake pads (see table 11.1).

Brake pad replacement:
Before replacing the brake pads Pos. 1, ensure that the mass held by the brake is secured to
prevent movement, as parts of the brake must be loosened/removed for replacement.
Before replacing the brake pads switch on the electric current (the solenoid opens the brake) and
secure the the brake with the assembly locking nut Pos. 25 and washer Pos.26 (see Fig. 5.1) by
hand. Switch off the electric current.
Remove all tension springs Pos.5 and one of two retainig plates Pos. 6 each side, see Fig. 11.1
Pull out the old brake pads and screw out the set screws Pos. 17 and Pos. 41, Fig. 8.1, so that
the new brake pads can easily inserted. Take care, that the chamfer on the brake pad is on the
outer diameter of the brake disc and the friction material of the brake pad is on the brake disc
side. Fasten the retaining plates again (tightening torque, see table 11.1).

Tab. 11.2
After replacing the brake pads, you have to adjust the air gap between the brake disc and the
brake pad See (chapter 11.2 ). After replacing the brake pads remember the chapter 8.5. The en-
tire surface of both brake pads must be in contact with the brake disc in order to achieve the opti-
mum braking effect. The brake pads must also be heated briefly to approx. 200°C. Therefore,
multiple brief braking operations under low spring force and rotating brake disc are required to
heat the brake pads.
12. Accessories: switches for brake closed, brake open and brake pad wear adjustment
Necessary (Option)
12.1 Installing and connecting the inductive proximity switches for brake closed, brake open and
brake pad wear adjustment necessary
Danger to life and limb!

Danger!
When switching the brake, the lever Pos. 29 and the spring compressor Pos. 27
will move very fast.
The inductive proximity switch must only be mounted and adjusted after the brake has been
adjusted (chapter 8).
The assembly of the inductive proximity switch is only possible after the brake is assembled and
the air gap between brake pad and brake disc is set correctly (see chapter 8 and 9). To indicate
„Brake open“, „Brake closed“ or “Brake pad adjustment necessary” a inductive proximity switch
for each request is to assemble. The inductive proximity switch is part of the sensor kit and
supplied loose as accessory. The sensor kit consists of an inductive proximity switch with two
fastening nuts, a fastening sheet metal and fastening screws and washers. On the brake housing
you can find threads to fasten the fastening sheet metal (see Fig. 12.1). On the metal sheet you
have different assembling possibilities for “Brake open”, “Brake closed” and “Brake pad wear
adjustment necessary” (see Tab. 12.1). You always get a signal for brake status. With one sensor
kit you can detect only one brake status, for further signals you have to order another proximity
switch in NC or NO version (see figure 12.2; 12.3 and 12.4). For sensor kits with more than one
sensor or for special requirements, such as other voltage ranges or low temperatures below -
25°C, please contact RINGSPANN.

To adjust the inductive proximity switch for brake pad wear, you can increase the airgap between
brake disc and brake pad on each side to a value of 0,6mm. Then switch off the brake (brake is
closed). Then fasten the inductive proximity switch in a way that the LED is almost glowing. Then
reduce the airgap to 0,3mm again. Switch on the brake, the LED must not glow after the brake is
in open position. Test the proper function by switching the brake. The LED of the proximity switch
must glow, if the brake status you want to detect is reached.
