Outer diameter 12 mm 

10.

 

Standard configuration in 100 m coils 

  
 

  

The T154 WS control unit has the selection n.o (normally open contact) / n.c (normally closed contact) for the ALARM, TRIP 
and FAULT relays, programming steps from 26 to 31 page 14. Selecting the YES/NO setting introduces the Fail Safe and No 
Fail Safe functions. 

 

 
ALARM AND TRIP   
By setting NO (NO Fail safe) the normally open contacts are in positions 5-7 Alarm and 8-10 Trip, they switch only when the 
pre-set temperature limits are reached. 

 

By setting YES (Fail safe), the normally closed contacts are in positions 5-7 Alarm and 8-10 Trip, they switch only when the 
pre-set temperature limits are reached or as a result of no voltage.  

 

 
FAULT 
By setting YES (Fail safe), contact 11-12 is positioned as normally open, switches (closed) when a fault condition is identified; 
see paragraph on alarms and ventilation on page 12.  

 

Setting  NO  (NO  Fail  safe)  the  contact  11-12  is  positioned  as  normally  closed,  switches  (open)  when  a  fault  condition  is 
identified; see paragraph on alarms and ventilation on page 12.  

 

If the fail safe function is disabled on the fault contact, the control unit will no longer be able to signal the fault due to power 
failure. In this case it is advisable to enable the Fail safe on the ALARM contact for the afore-mentioned indication. 

 

 
NOTE: when the control unit is in one of the modes indicated below, it does not perform any thermal monitoring, moreover 
the relays will all be disabled

 

the FAULT led will flash.   

 
• Vis. display programming. 
•  PRG programming. 
• Test of the relays. 

     
    The FAIL SAFE function is temporarily disabled and the FAULT relay switches.  
    
   

ATTENTION: Entering the relay test mode temporarily disables the failsafe function.  The relays with function       

 

                   enabled switch (ALARM-TRIP-FAULT).
