Typical Function Of The Atc-300 Controller - Eaton ATC-300 Mode D'emploi

SECTION 4:TYPICAL FUNCTION OF
THE ATC-300 CONTROLLER
The ATC-300 Controller operates as follows.
The input connections of the ATC-300 controller are wetted
and work on an opening or closure of an external contact.
The output connections are dry contacts and function
depending on input connections and / or source availability.
120 Vac, 60 Hz is required to power the ATC-300 controller.
Power is supplied to either pins 1 and 2 or 3 and 4 on the J-7
connector.
Source 1 (S1) sensing is supplied on the J-1 connector;
Source 2 (S2) sensing is supplied on the J-2 connector.

K1 and K2 relays, located on pins 1 and 2 (K1) or pins 3 and
4 (K2) on the J-5 connector, are use to control device posi-
tion. S1 and S2 inputs are located on pins 1 and 2 (S1) or
pins 3 and 4 (S2) on the J-4 connector and are used to sense
device position.
K1 closes until the S1 input is satisfied but no longer than 6
seconds before the S1 device Alarm is triggered and the K1
relay is deenergized. The K2 relay functions the same as the
K1 relay in that it closes until the S2 input is satisfied (closed)
but no longer than 6 seconds before the S2 device Alarm is
triggered and the K2 relay is deenergized. Either input MUST
be satisfied prior to resetting the Alarm. The S1 and S2 con-
nected inputs are wetted inputs that require a contact closure
in order to be satisfied.
