Description; Technical Characteristics - c.a.p.t. 1.12.310 Instructions Manual

DESCRIPTION

The motor (E) installed inside the control box 1.12.310 is three-phase induction brake type "COEL" - F71B4-B14. To
the motor are directly connected a reduction gear and an electromechanical terminal board with limit switches. Motor
and auxiliary wiring diagram are represented in the enclosed drawing. Inside the control box take places a heater with
an adjustable thermostat, in order to avoid formation of condense. Motor dimensional and electrical characteristics are
reported in the specific enclosed (catalogue copies).
On internal door are assembled many components like emergency button (SB1), safety lamps for three phase (motor
circuit) (HL1) and single phase (auxiliary circuit) feed to indicate voltage inside the control box (HL2). Moreover, take
place a signal lamp for the wrong phases cyclic sense (HL3) (has to be switched-off when the three phases are cor-
rectly connected) that illuminate after the first running impulse in case phases cyclic sense being wrong. Than, signal
lamp burning when the adjustment operation is out of position (HL4), 1-N (SH1) and N-1 (SH2) push buttons, three
phase input disconnecting device (QS1), local/remote switch (SA1) and the operation counter (CC). On the doors there
are keys. Keys to prevent operation by unauthorized personnel must lock doors.
On auxiliary circuit is provided a H.V. contact with two terminals X2:1 e X2:2. They must be connected to the transfor-
mer's high voltage bus-coupler switch. When the two contacts are closed the high voltage bus-coupler switch must be
open, therefore the transformer is de-energized and it is possible to work with the motor drive.
If the transformer causes extremely strong mechanical vibration, we suggest fixing the motor drive 1.12.310 by vibra-
tion absorbers.
Terminal board X4 has dead contacts (without voltage) for remote signal of positions.
On request, we also supply a remote-control-box. 1.12.350.

Electrical control: by an impulse of about half-second. The tap changing operation will be automatically finished.
Position indication: mechanical, on the control box by a fixed window is possible to read the corresponding position;
electrical, by free terminals on "X4" terminal board for remote lamp panel.
N.B. For different Voltages read the specific attachment.
