11.4 Special version of lift devices (integrated contactors, integrated reactance coil)
1) Both DSV 5445-Lift and DSV 5453-Lift can be delivered as the following variants:
Standard Device with side AddOn motor/line filter.
PLUS Device with side AddOn motor/line filter motor contactors, brake contactor, brake
rectifier, line reactor.
PLUS synchron
Device with side AddOn motor/line filter motor contactors, brake contactor, brake
rectifier, line reactor.
In case of synchronous motors the short-circuit, caused by contactor K3Z effects that
the drive trundles slowly away, even if the brake is opened.
2) Additional terminals are provided on the full version of the DSV 5445-Lift (or DSV 5453-Lift) device,
which are assigned as follows:
The upper row for the motor contactor controller is assigned as follows:
A1 A2 Y 32 33 34 35
A1 and A2 are the solenoid terminals for the motor contactors. The solenoid voltage is 230 V AC. The power
contacts are already wired internally; one pair of contacts is interlinked with the AC circuit of the brake
rectifier.
Terminal Y together with terminal L (in the lower terminal strip) forms the contactor interlock with the brake
rectifier. Y is brought out only for inspection purposes; this contact is needed only when the internal brake
contactor should not be used for certain reasons.
The auxiliary normally-open contact is connected to 35 and 33 (to connect the enable signals "ISP" and/or
"E0" on DSV 5445-Lift). The auxiliary normally-closed contacts on the motor contactors lie alternatively
between 34 and 32.
The lower row for the brake controller has the following terminals:
A9 0V 4D 4L NL L 8 7
A9 and 0V are the solenoid terminals of the brake contactor. The solenoid voltage is 24 V DC. The solenoid
can be supplied, for example, from the converter output (i.e. by the associated 80 mA output "A9" at the DSV
5445-Lift).
40 and 4L are for the terminal of the brake magnets (this is already a DC voltage) and NL and L are the AC
supply (max. nominal voltage 240 V AC).
This circuit is, of course, already interlocked with the two motor contactors. Contacts 8 and 7 provide an
additional free normally-closed (!) contact (the three normally-open contacts are located on the DC side, in
this case).
The brake contactor (terminals A9 - 0V) possesses a 24 volt coil and can be fed
directly from A) connector X1.
