Product Line:
Altistart 46

Environment:
All

Cause:
Replacement

Resolution:
The direct replacement is ATS48.

Here are a few things to consider when converting an ATS46 to ATS48 unit.

The ATS46 uses an N at the end of the part number and the ATS48 uses an Y at the end of the part number.

The dimensions will be different. In most cases the ATS48 is smaller than its equivalent ATS46.

The ATS48 has a built-in keypad, the ATS46 uses a removable keypad. The VW3G48101 is the remote mountable keypad kit for the ATS48.

The shorting contactor is connected from A1 to A2, B1 to B2, C1 to C2 on the ATS46. On the ATS48 connect the shorting contactor from L1 to A2, L2 to B2, L3 to C2. Suggest using power distribution block for the input connections of the shorting contactor.

The ATS46 had 460vac control power (a built -in control transformer is present on ATS46 soft starts). The ATS48 does not have a control transformer built-in. The control power for a ATS48 is 90-270vac and is customer supplied. Customer's typically use 120 vac for the control power for ATS48 soft starts.

The ATS 46 had a NC (R1B-R1D) or a NO (R1A-R1C) for the fault relay.
The ATS46 had a NO (R2A-R2C) for the End of start-up relay.

The ATS48 has a NO (R1A-R1C) for the fault relay.
The ATS48 has a NO (R2A-R2C) for the End of start-up relay.
The ATS48 has a NO (R3A-R3C) for a programmable relay.

The ATS48 does not have a NC relay (R1B-R1D on ATS46), if that contact is being used, you need an interposing relay on the ATS48. Then wire to the NC contact on the relay
(Recommend ice cube relay w/ N/O-N/C cont. w/ coil voltage to COM) – (i.e. 8501RSD41V53 with base 8501nr41)
