LRV lift control valve

Installation and commissioning

300−I−9010212−E−10/08.08

4.2.4

Electrical emergency−lowering 2 x 24 VDC

Important

: the operator must undertake any further measures required

to ensure short−circuit and overvoltage protection.

If a mains (line) failure occurs, the power supply unit can be powered by
an external battery supply (2 x 24 V) through terminals 12, 19 and 20.

Relay R

drops out when there is a power failure and the two nor-

mally−closed contacts R

−1

and R

−2

connect to the battery

Inputs 19 and 20 have diode−protection from polarity reversal or feed-
back to the battery

The lift can be lowered to a predefined stopping position by means of
"Slow DOWN" or auxiliary speed K6...K8 (travel signals are gener-
ated by the lift control system).

Important

: only possible with 2 x 24V (or 4 x 12V) batteries

Slow DOWN

Auxiliary speed
