LRV lift control valve
Product description
300−I−9010212−E−10/08.08
1.4.2
Description of function
S
The lift control system sends the command signals to the C−DELCON
via potential−free relay contacts or semiconductors (K1−K4)
S
The feedback value is compared with the demand travel curve
throughout the whole travel.
S
Deviations from the demand curve are corrected by the UP and
DOWN proportional solenoids
S
The closed−loop control ensures that the travel characteristics are
independent of load and temperature
S
The inspection speed can be set through contact K5 of the lift control
system (there is no SIU−1 monitoring during inspection speed with
K5!)
S
Reduced speeds for short travel distances are also possible via
K6−K8
S
The C−DELCON enables soft−stopping (gentle halt) with very accu-
rate positioning (
±
3 mm)
Features
S
The travel curve for the up and down directions is set and adjusted
with the Handterminal or a PC
S
The demand curve can be set and checked at the C−DELCON while
the lift is at standstill
S
Measured values can be checked with the Handterminal
S
The C−DELCON card is easy to exchange (1 card for all valves),
which means that rapid fault−fixing is ensured
Important
: If the C−DELCON is exchanged, the installation−specific
parameters must be replicated in the new card.
