Contactor - Honeywell AS302P Operating Instructions Manual

AS302P Single Phase Smart Meter

____________________________________________________________________

Before connecting an external circuit to the Auxiliary Relay Terminals, read the Warnings in Section 2 of

this manual.

A single pole, 100A Contactor is provided in the AS302P.

Contactor Technical Details are given in Section 29.2.

Note that in normal use, the user can Enable the Supply if the Contactor state is Ready for connection (Armed) using the

meter display. Go to General/Contactor and a long press on the "SELECT" button will show PIN code entry for validation

(if enabled). If validation is successful, the Supply status is changed from Armed to Enabled.

The Contactor Display Icon will be 'Flashing' when it is 'Armed'.

Once Armed the Contactor can be Closed By:

-

The Customer pressing a Pushbutton on the Display (PIN)

-

The Customer using the PPMID (PIN)

-

A Command from DCC

The Contactor State will be Locked If:

-

A Disable Command is received from the DCC

-

A Tamper Event is detected and the meter is configured to Disable the Supply

If the Contactor is in a 'Locked' state (Contactor Open and Supply Disabled), this will be shown on the display. It can only

be re-enabled by a Command from the DCC to either Arm or Enable the Supply.

Once the Arm Command is received then the meter changes the state from Locked to Unlocked and needs to determine

what state the Contactor should be in (according to the Meter Logic):

-

If it should be Disabled, the Contactor Remains Open

-

If it should be Armed or Enabled, the Contactor will be put into the Armed State

Once the Enable Command is received, the meter changes the state from Locked to Unlocked and needs to determine

what state the Contactor should be in (according to the Meter Logic):

-

If it should be Disabled, the Contactor Remains Open

-

If it should be Armed or Enabled, the Contactor is put into the Enabled State

The status of the Contactor can be determined from the meter display or via the HAN for display on any Type 1 or 2

Devices.
