Protections 

Thermal  protection:

  The  electronics  are  equipped  with  reducing  thermal  protection.  This 

function  is  a  temperature  limiter  which  reduces  the  output  power,  when  temperature  on  the 
controller rises over 

75°C. In this case relay error function set output error. 

In the event that the temperature of controller is still rising (over 105

°C) the controller stops the 

motor. 

When  the  temperature  controller  falls  below  75°C,  the  motor  automatically  restarts. 

Thermal protection is disabled in fire mode state.

 

 

Under  and  over  voltage:

  The  electronics  are  equipped  with  under  and  over  voltage 

protection.  Electronics  shutdown  when  the  main  voltage  is  not  in  the  required  range.  See 
mechanical and electrical specification. 
 

Blocked  rotor  protection:

  The  electronics  are  equipped  with  blocked  rotor  protection  when 

the rotor of motor is blocked or it is impossible to rotate it. Electronics automatically retries 25 
restarts, than a manual restart by disconnecting the power supply is required. 
 

Motor  phase  fail  /  lose:

  The  electronics  are  equipped  with  motor  phase  fail  protection  in 

event that one of phase motors is damage or missing. In this case electronics stops the motor

 

immediately. Protection is disabled in fire mode state. 
 

Phase  overcurrent  protection:

  The  electronics  are  equipped  with  phase  overcurrent 

protection when current through motor

 

increases up to 10A. In this event electronics stops the 

motor immediately and tries to makes automatically restart. 
 

Rotor  failed  acceleration:

  The  electronics  sre  equipped  with  rotor  failed  acceleration 

protection when the rotor is damaged or is hard to rotate. Electronics automatically retries 25 
restarts  for  every  1second.  If  the  25

th

  restart  is  still  unsuccessful,  then  manual  restart  by 

disconnecting the power supply is required. 
 

Note! 
Heating the controller over the maximal temperature is not allowed. 
Above 

105°C electronics stops the motor (not in fire mode state), and 

restarts  it  again  when  the  temperature  of  controller  falls  below 

75°C. 

However,  if  the  controller  is  overheating  and  motor  was  shutdown, 
disconnect power supply (safety switch) and wait at least 20 minutes 
before  you  service  them.  In  case  of  overheating  of  controller,  the 
metal parts of them  are very hot and could  cause serious  damage to 
your skin. 
If controller starts reducing output power during running, this may be 
reason  of  overheating.  In  this  case  add  small  24V/40mA  fan  on 
controller or ensure air flow through the ribs. Fan can be supplied by 
power  from  controller  (chapter  4.2. 

–  wiring  diagram).  Overheating 

problem  appears  in  the  case  of  installation  of  the  controller  in  the 
space without air flow.
