6.4 Heater Break Alarm 

 

Heater Break Alarm is a microprocessor based circuit to diagnose partial or total load failure and 

short circuit on SCR and fuses failure. 

 

• 

discrimination better than 20%; 

• 

latching alarm plus reset; 

• 

relay output 0.5A at 125VAC. 

 

 

Minimum current 3A. If load current is below this value make two turns or more 

around current transformer. H.B. circuit also diagnose fuse failure. 

 

H.B. circuit reads load current via a current transformer 25-50/0.05 or 100/0.05 depending on 

thyristor size.

The thyristor unit is supplied with a normally closed (N/C) contact. 

 

 

In alarm condition and without auxiliary voltage the contact is closed (relay coil not 

energized). In normal condition (no alarm) the contact is open (relay coil energized). 

 

 

 

 

6.4.2 Reset  

 

To reset Heater Break Alarm open RESET contact on terminal 3-4.
