Warnings 

 

 Failure  to  follow  the  instructions  in  this  manual  and  on  any  plates  attached  to  the 

product  exposes  persons  to  risks  and  may  cause  damage  to  the  equipment  and 
machinery.

 

 

˗

 

The product must not be used at an ambient temperature lower than -20 °C. 

˗

 

The disc must be made of iron alloy (cast iron or steel) having a hardness in the range 190 to 220 
HB. 

The  technical  department  of  COREMO  OCMEA  can  provide  additional  information  in  order  to  ensure 
correct application and use of the product. 

Dangers caused by a power failure

: A power failure will  cause the brake  to be  applied suddenly.  It  is 

therefore  necessary  to  provide  an  uninterrupted  power  supply  or,  if  the  case  requires,  use  suitable 
power failure warning systems as a brake failure may cause personal injury and damage to property. 

Danger  of  breakage  during  operation

:  To  reduce  the  risk  of  breakage  during  operation  carry  out  the 

periodic inspections shown in this manual. 

Risks  connected  with  changes  in  operating  conditions

:    The  products  are  designed  for  the  purposes 

stated in this user and maintenance manual therefore the minimum power supply pressure is indicated 
to ensure that the brake can be opened and the maximum pressure to ensure that braking is always safe 
and reliable. The operating conditions also vary depending on the diameter of the brake disc used; an 
equation  for  calculating  the  dynamic  torque  as  a  function  of  disc  diameter  is  given  in  this  manual.  It 
should be stressed that an error in calculation will result in a braking torque that is different from the 
desired value and this may represent a risk to safety. 

Residual risk

: Residual risk can be attributed to the operator not following all the procedures stated in 

the user and maintenance manual and not giving due consideration to the warnings.
