2 Safety
2.1 General safety regulations
The pawl device may only be operated in a technically perfect condition and in accordance with its
intended use, in a safety-conscious and hazard-conscious manner, in compliance with the manual, the
applicable accident prevention regulations and the guidelines of the local electricity supplier.
This manual is a supplement to the FST manual and the FST Installation and Commissioning manual whose
safety guidelines must always be observed.
2.2 Handling electronic assemblies
Electrostatic charge
›Keep the electronic assembly in its original packaging until installation.
›Before opening the original packaging, a static discharge must be performed. To do this, touch a
grounded piece of metal.
›During work on electronic assemblies, periodically perform this discharge procedure.
›All bus inputs and outputs that are not in use must be equipped with a terminator.
ATTENTION:
The system is only to be put into operation with the ASV switched off (learn drive, calibration and ush
positions).
The ASV is not put into operation until the system has been set correctly.

3 Pawl devices
3.1 Functional principle of a pawl device
The pawl device prevents the car from sinking when loading heavy loads in lifts with large loads (e.g. by
stretching the suspension ropes or compressing the hydraulic oil).
An electromagnetic or electro-hydraulic locking device xes the ush position and thus prevents
movement (step formation) of the lift during loading and unloading.
The follwoing illustrations explain the functional principle using the example of an electromagnetic lock.

2 Car bottom 5 Magnet
3 Locking bolt
3.1.2 Function steps using the example of an upward movement
The lift rst passes the stop (1) and stops. Then the locking bolts are extended (2) The lift then sinks
onto the support brackets provided for this purpose in the shaft of the landing (3).

Pawl devices
8Manual pawl device
When leaving the stop, the car is raised a certain distance (4) and stops. Then the locking bolts are ret-
racted (5) to allow the car to continue its journey (6).

3.2 Support bolt
Rope and hydraulically operated lifts can be equipped with pawl devices of different interlock types.
The control for the landing gear must be adapted to the respective conditions. Each bolt is (must be)
monitored separately in the end position with a contact.
3.2.1 Electromagnetic support bolt = „Solenoid-Pawl“ YES
The touchdown bolts are extended and retracted via controlled electromagnets. As a rule, these are
electric lifting magnets. When controlled, the bolt is tightened. In the de-energised state, the bolt drops
down to the touchdown position pretensioned by a pressure spring.
3.2.2 Electro-hydraulic support bolt = „Solenoid-Pawl“ NO
The oil pressure generated by a hydraulic pump is used via controlled valves to retract or extend the
hydraulic touchdown bolts.
A hydraulic unit, which is usually located on the car, extends and retracts the touchdown bolts.
This is to be set via the following parameters:
..Drive / Pawl control / Solenoid-Pawl: Yes/No
See chapter 5.2.2 Drive parameter settings, on page 16.

If certain states are not reached due to missing feedback or timeouts, the corresponding error code is
indicated in the diagram.
See chapter 6 Error messages, on page 20.
4.1.1 Pawl device for rope lifts
The drive must be adjusted in such a way that it is able to correct (catch up) even a few millimetres.
ASV operation on rope systems usually only prevents the car from sinking, as the car becomes lighter
during unloading and is „pulled away“, i.e. lifted, by the (now heavier) counterweight.
The pawl control does not „hold“ the car.
Settings see chapter „5.2.2 Drive parameter settings“ on page 16.
4.2 Components
The following additional components are required to control a pawl device:
›RIO-2-Module - for bolt control
RIO-2
›Contactors and relays - for signal coupling and power transmission
›Optional: additional suspension cable - for signal transmission between car and machine room.
›Safety circuit bypass control- magnetic switches and magnets for bridging the bolt switches within the
bolt zone.
The bolt zone is the area in which the car can move with the bolts extended without colliding with a landing
bracket.
The length of this zone must be dened by the installation company.

Overload
Interrogation of the pressure switch Overload.
The overload cannot be measured in the mounted state
See chapter 4.5 Overload measurement, on page 12.
Car mounted
Interrogation of the pressure or limit switch for the mounted car (NC function).
The car up signal can be generated in two ways:
›Mechanical switches on the landing troughs, which are actuated by the extended landing pins when the
car is in position.
›Pressure switch on the hydraulic unit of the drive, which signals that the car is in the raised position
when the pressure falls below a dened threshold.
Re-pump (NO contact function) (NO)
Interrogation of the pressure switch when the car has been in the open position for a long time
(normally closed function).
The signal Re-pump prevents a complete loss of pressure in the hydraulic cylinder during long idle times
with the bolt extended.
The signal Re-pump can be generated via two variants:
›Additional pressure switch on the hydraulic unit, which triggers pumping when the pressure falls below
a dened threshold.
›Slack rope switch (for hydraulic rope systems)

Control for pawl devices
12 Manual pawl device
Re-pumping must never lead to the „loss“ of the „Set up“ message (opener function)!
Fine adjustment
Control of an optional ne adjustment pump for slow lifting of the car.
Hydraulic power packs with a high output work more efciently if they are used together with an
additional ne adjustment pump with a lower output. The ne-adjustment pump performs the short
readjustment and repumping operations without switching on the main power unit. This is benecial
for both energy consumption and driving behaviour.
The ne adjustment pump ensures
›a slow lifting of the car with the bolts extended
›a pump-up to prevent pressure loss in the hydraulic cylinder
Without a ne adjustment pump, the car is raised slowly via the main pump.
Fine lowering
Control of an optional ne lowering valve for slow lowering of the car. Without a ne lowering valve,
the car is lowered slowly via the main pump.
4.4 Safety circuit and Safety circuit bypass control
Safety circuit
The contacts of the signals bolt retracted and bolt extended are integrated into the safety circuit. This
means that the car can only be moved within the bolt zone when the bolts are extended.
Safety circuit bypass control
Within the door zone, a safety circuit bypass control bridges
›the contacts of the signals Bolt retracted and Bolt extended,
to allow the car to be raised and lowered slowly in this area with the bolts extended.
›the car and shaft door contacts,
to enable pumping when the doors are open.
See chapter 7 Standard circuit diagrams, on page 21.
4.5 Overload measurement
Due to the largely pressureless hydraulic cylinder of the mounted car, the overload measurement required
by EN81 cannot be carried out by pressure measurement at standstill, as is usually the case, but must be
carried out using a measuring method that is independent of the hydraulic pressure.
Sequence of the overload measurement:
›The car is raised by the lifting distance or, for the time Lifting time Max.
›Measurement of the overload via the pressure switch input RIO-2 X3.7.
»measured weight OK?
-> ride continues
»measured weight to high
->The car is set down on the bolts, the car doors are opened and the car waits until either the light
barrier has been interrupted or the time set in Overload Stg. has elapsed.
›Overload condition is canceled and the process starts again.
See chapter 4.1 Functional principle of a control unit, on page 9.

Control for pawl devices
Manual pawl device 13
4.5.1 Overload measurement for rope systems
In contrast to hydraulic systems, in rope systems the overload must be implemented via sensors, e.g. via
rope or strain gauges.
Contrary to the usual procedure, the overall structure must be able to lift an overloaded car, as only
after lifting from the support bars a load measurement is possible.
If this is not desired or if it is not possible by design, other load measurement methods must be used,
e.g. load measurement via the car oor!
Lift type specic the touchdown of the car in rope lifts is not be regarded as equivalent to that in
hydraulic lifts. The load of the car is never completely placed. In addition, there is a relaxation of the
suspension rope when the car is unloaded, which results in the formation of steps. The pawl device
must therefore be regarded as a means of preventing the car from sinking when it is loaded. In order to
avoid the formation of steps during unloading, it is necessary to readjust the ush position.
