What are the function I can assign to relays (R1, R2 & R3) of ATS48.

How can we help you today?

Relay1 (R1)
- r1F: fault relay. Relay R1 is activated when the starter is powered up (minimum CL1/CL2 control). Relay R1 is deactivated when a fault occurs and the motor switches to freewheel mode. See the special case when the automatic restart function is activated and Faults - causes - remedies page 160 to 164.
- r1I: isolating relay. Relay R1 is designed to control the line contactor on the basis of the RUN and STOP commands and to indicate faults. Relay R1 is activated by a RUN command (or a preheating
command). It is deactivated at the end of braking or deceleration or when the motor switches to freewheel mode after a STOP command. It is also deactivated when a fault occurs. The motor switches to freewheel mode at this point.

Relay2 (R2) (cannot be assigned)
The end of starting relay R2 is activated when the starter is powered up, no faults are present and the motor has completed the start-up phase. It is deactivated in the event of a stop request or a fault. It has one normally open contact (N/O). It can be used to bypass the ATS 48 at the end of the starting phase.

Relay3 (R2)
- no: not assigned.
- tAI: motor thermal alarm.
- rnI: motor powered (indicates that there may be current in the motor).
- AIL: motor current alarm (threshold OIL and time tOL of PrO menu exceeded).
- AUL: motor underload alarm (threshold LUL and time tUL of PrO menu exceeded).
- APC: motor PTC probe alarm.
- AS2: second set of motor parameters activated.
