38. On hydraulically operated lifts, the creeping correction system is
activated as soon as the runtime monitoring is activated (terminal
42 = 1) and the lift is immediately shut down .
39. On hydraulically operated lifts, the anti-creep monitor is queried
as follows :
a) the up-creeping monitor automatically causes the car to be
returned to the bottom landing and shut down there. If the
runtime monitoring responds outside the landing area zone dur-
ing this action, the lift is blocked at once and the creeping correc-
tion system is not activated as the first malfunction registered was
»up-creeping monitor«.
b) the down-creeping monitor causes the lift to be shut down at
once. The creeping correction system remains operational.
40. The creeping correction system remains operational if a hydraul-
ically operated lift is overloaded.
41. The overload input is queried at standstill only (terminal 88).
42. The excess pressure switch of a hydraulically operated lift is con-
nected to terminal 35 and queried at this terminal as well. The
basic menu offers − depending on the function − the option to
select or deselect shut-down in case of excess pressure. The cir-
cuit diagrams also remind you of this option
43. A hydraulically operated lift can principally be equipped with an
emergency circuitry down (similar to emergency circuitry »up
only«). If an emergency circuitry down is installed, the following
switches may be bridged: shortfall in pressure, pipe rupture, bot-
tom limit switch and safety gear contact.
C
AUTION
!
A combined safety gear contact/slack rope switch must not be
bridged, nor any other switch. The following applies for the emer-
gency circuitry »down«:
a) The bottom emergency limit switch must not bridged !
b) An emergency circuitry »down« must not be applied in lifts
with 2:1 suspension without slack rope switch!
A
TTENTION
!
Operating instructions and labels on the emergency circuitry unit
must inform about risks !
Example: A defective hydraulic hose or a defective threaded hose
coupling causes the hydraulic oil to be pumped into the shaft pit!
44. The hydraulically operated lift must conform to all stipulations set
out in the relevant local "water protection regulations"!
