Operating Instructions For Lifts In Tandem Lay-Out - StertilKoni ST 4175 Gebrauchsanweisung

2.6 OPERATION INSTRUCTION FOR LIFTS IN TANDEM LAY-OUT
Two lifts can be joined lengthwise to be able to lift long vehicles.
These lifts are provided with a selector switch (see fig. 2.2). If the position of the selector switch is changed
during operation, then both control boxes are automatically disabled.
Selector switch position 1 (single mode)
Both lifts can be operated independently, with the selector switch in position 1.
Operation is according to the operation instructions as described in § 2.4.
Selector switch position 2 (synchronous mode)
Both lifts must be totally lowered before the selector switch is turned to position 2. This is the default
position for synchronisation of both lifts. Turn both main switches to the 0-position (OFF). Set the selector
switch to position 2 and turn both main switches to the 1-position (ON). The lifts are now operational in
synchronous mode.
Operation is according to the operation instructions as described in § 2.4.
Selector switch position 0
Operation of both lifts is disabled.
Height differences
Height differences are levelled out by the system. The control limits for height differences are:
Start height correction difference between lifts:
End height difference correction between lifts:
Fault situations will disable the control system (e.g. height differences, see § 5.1.2 fault display). Lower
both lifts independently (in single mode, selector switch position 1). Try to raise the lifts in synchronous
mode again (in tandem mode, selector switch position 2).If fault is repeated consult the service department.
