The ATS46 normally closed contact, R1B-R1D, is not included with the ATS48. How is this function provided with the ATS48?



Add an interposing relay with a normally closed contact (plus a normally open contact if needed for other purposes). Energize the relay coil using the ATS48 normally open contact, R1A-R1C.  Then use the normally closed contact of the relay for the control circuit function.  

ATS48 relay specifications :
Minimum switching capacity: 10 mA for 6 Vdc
Maximum switching capacity on inductive load:
    1.8 A for 230 Vac and 30 Vdc
    Maximum voltage 400 Vac.
