4.8.3 

Soft limiter 

This function is available for firmware version 4.0.0 or higher. 

 

 

Use of the Soft Limiter function as a limiter is not permitted for 
ATEX 

and 

IECEx 

applications 

according 

to 

IEC/IEEE 60079-30-1. 

Explosion protection is not ensured by this function. 

Use  hardware  limiter  of  ESTM-L  (SIL  II)  as  limiter  for  ATEX 
and IECEx applications according to IEC/IEEE 60079-30-1. 

To activate the smart limiter set the Sensor Mode to 

both

 and 

the  Controller  mode  to 

soft  limiter

  see  also  chapter  4.8.6 

Sensor Setup. 

If  the  set  temperature  limit  value  (Set  Point  Soft  Limiter)  is 
exceeded,  the  load  relay  or  the  load  is  switched  off 
permanently until a reset is done. This reset can be done by 
the user or by means of the smart reset function. 

Reset  is  possible  if  actual  temperature  (Actual  Value  Soft 
Limiter) at the sensor 2 (TC2) is lower than the set point (Set 
Point Soft Limiter) minus the set hysteresis (Hysteresis Soft 
Limiter). 

Sensor errors (wire breakage, short circuit, etc.) are detected 
automatically. In the case of a sensor error, the load relay or 
the load is switched off permanently until a reset is done by 
the user. 

Smart Limiter Reset 

The Smart Reset function automatically resets the soft limiter 
when  the  actual  temperature  (Actual  Value  Soft  Limiter)  at 
the sensor 2 (TC2) is lower than the set point (Set Point Soft 
Limiter) minus the set hysteresis (Hysteresis Soft Limiter) and 
Smart Reset Status is active. 

T-Off delay is the time that must have passed after the load 
is switched off to enable the Smart Reset. 

Remaining  T-Off  delay  shows  the  remaining  time  until  the 
Smart Reset can be enabled. 

The Smart Reset status 

Enabled

 means that the Remaining 

T-Off delay time has expired or the load has been switched 
off by the controller. 

The smart reset status 

Wait

 means Wait until the Remaining 

T-Off time has passed. 

The Smart Reset status 

Disabled

 means that Smart Reset is 

not  possible  because  the  load  is  switched  on  or  the 
Remaining T-Off delay time has not passed.
