Planning the system
10 SA3-SInstallation&CommissioningManual
4 Planning the system
In order to use the SA3-S safety system together with a lift system, the following requirements must be satised:
1. The lift control system must make available a signal that always becomes inactive when the car
is not to be moved ("in motion" signal). This signal must be inactive on each stop. Level: 0V (car is
moving) / 24V or high impedance (car is not moving). The signal is needed in order to test the solenoids
at the overspeed governor and to allow that the magnetic coil drops with closed doors (quiescent state
of the lift).
2. The product must be supplied with power via a 24V emergency power device.
Reason: If power fails during travel, the solenoids must remain energised until the car stops, as the
safety gear will otherwise be actuated. This delay is taken into account in the device, but can only take
effect if the power supply is ensured for several seconds following power failure. Required is 24V/1A
for about 10 sec. In addition, an UPS is needed in order to energise the solenoid during an emergency
rescue so that the car can be moved. The emergency power supply must be designed accordingly.
3. An override input ensures that the car can also be moved in the event of a power failure so that per-
sons can be freed.
In the override state, the solenoid energises and the safety circuit relay opens. Level: 0V (override) /
high impedance (normal operation). For override, a separate switch must be wired in the control cabi-
net. It is to be labelled with "Ovrd. SA3-S".
4. The safety gear that is to be used in combination with the SA3-S must satisfy the requirements of EN
81-1:1998 + A3:2009 or EN81-2:1998 + A3:2009
5. The car apron must satisfy the requirements of EN 81-1:1998 + A3:2009 point 8.4.
An apron acc. to EN 81-21 is permissible only if the car apron satises the requirements specied in
EN 81-1, section 8.4 over the entire shaft upon leaving the lowest oor. If this cannot be ensured, the
calculation of the permissible upward stopping distance (see chapter "Upward stopping distance") can
only take into account the vertical part of the car below the car threshold for the apron length.
6. A formula must be used to theoretically verify that the car achieves the stopping distance specied in
the standard. The "upward" and "downward" cases are to be calculated separately. The following data
are necessary for this purpose:
› Maximum length of the door zones in the up and down directions (normally 200mm in both
directions)
› Maximum reaction path of safety gear and overspeed governor (the path of the car from the
time the safety cable is blocked until the safety gear reaches its guaranteed braking decelera-
tion) in both directions
› Minimum braking deceleration of the safety gear in both directions
› Internal passage height to the car interior (for calculating the maximum downward stopping
distance)
› Length of the apron below the car (for calculating the maximum upward stopping distance)
› Mass of empty car, cable and counterweight (for calculating the maximum possible upward
acceleration)
The product may only be used if the required stopping distances can be achieved. For some parame-
ters, standard values may be used.
7. The safety circuit of the lift system must be modied according to the specications. In the standard
device, the safety circuit voltage is 230V / 50Hz. Other voltages are possible on request.
8. The PowerGood input signals a power failure at the control system. Level: 24V: current present / 0V or
high impedance: power failure. Ideally, this input is supplied by the power supply of the control system.
9. If the system is equipped with the "approach with open doors" function, the two door zone signals
must be wired. These signals must also be monitored by an external safety circuit bypass control. Level:
24V (door zone) / 0V or high impedance (outside of the door zone).
10. To reset the product in the A3 case or after an error, a button ("reset") can be wired in the control
cabinet. Level: 24V (reset) / 0V or high impedance (normal operation). The button is to be labelled with
"Reset SA3-S". Alternatively, the SA3-S safety device can be reset with the aid of a magnet below the
display.
11. The "error" output of the product can be wired with an error lamp (24V, max. 0.7mA) or with the control
system. This output is for information only and is not a safety function. The error lamp is not necessary if
the device display can be viewed.If the error output is read by the controller, the controller must not stop
the system in case of an error.
Planning the system
SA3-SInstallation&CommissioningManual 11
12. Reset button and error display can be replaced by a "display module" in the control cabinet.
13. Position: SA3-S generates a two-channel incremental output which can be used as a position input for
the control system. The resolution of the output is better than 1mm. Level: differential driver stage (2x
two-wire)
14. For the purpose of the arrest test, a button (N.C.) can be connected in the power supply of the device
(connection B-3). Upon actuation of the button, the solenoid on the overspeed governor deenergises
and the safety gear is triggered.
15. The SA3-S safety system can be installed in hydraulic lifts. If a double-acting safety gear is used here,
the same premises apply as to rope lifts. If only one safety gear should be used in the downwards direc-
tion, the following requirements must be met:
› Safety gear in the downwards direction must conform to the requirements of EN81-2:1998 +
A3:2009.
› According to EN 81 the speed restrictor must also have force guided safety switches which
opens the safety circuit in upward direction during magnet releasing.
› Voltage of safety circuit must act directly on the braking element (e. g. motor contactor), i. e. by
opening the safety circuit the car must come to a standstill through gravitational force.
16. In case of hydraulic lifts the safety gear should not get jammed, during the car with the releasing sole-
noid coil is sinking slowly. For that prupose, the controller might activate the signal „in motion“for a short
time.
17. The SA3-S safety device has electronic inputs. In order to avoid disturbances of the system, carry out
suitable interference suppression measures. These include:
› Suppression circuits of all inductors (contactor, relay, brake systems…)
› Suitable line lter for disruption of safety circuit from motor control
› Suitable shielding of the cables to the motor and to the the inverter etc.
› As possible a separate laying of the disturbing cable lines
18. Your order should indicate the connection variant (NEW LIFT cable or standard cable)

5.1 Circuit variants
There are 4 valid circuit variants for the SA3-S safety system. The following information applies to all variants:
› In case there is no door bypass in the system, the two door zone inputs are not required, they are left open. The
rest of the circuit will remain consistently. It is advisable to use in this case variant 2.
› Both GND potentials (from the power supply 24V and 24V emergency power supply) can be connected together
externally.
› If the system has the auxiliary control, the safety circuit relay can be placed in the safety circuit, where it is
bypassed by the auxiliary control. Safety circuit relay can be located at any position in the safety circuit, e.g.
also in front of the door contacts.
Attention! During simultaneous use of override and auxiliary control make sure that all shaft and car doors are
closed.

4 The unspecied input levels can be set to the opposite potential or be high impedance.
PowerGood (A-1):
The signal indicates to the safety device whether the power supply of the lift is OK. During emergency power
operation, the safety device is separated from the power supply 10 sec. after the car is stopped to avoid loading
the supply batteries unnecessarily.
Error (A-2):
The output indicates that an error which must be reset manually has occurred in the device. A small signal lamp
can be operated on this output. Alternatively, the error can be read on the display.
Door zone (A-3, A-8):
The two door zone inputs indicate that the car is currently in a door zone. They must be independent of one
another (2-channel).
The door zone inputs must be monitored by a tested safety circuit bypass control (EN81-1, 14.2.1.2) which
prevents operation of the lift in case of an error (EN81-1, 14.1.2.3.2.1.).
The door zone inputs are not connected, if the installation has no door bypass (the safety circuit bypass control).
Override (A-4):
If the override input is set to GND, the solenoid energises. It is used for freeing persons. If the safety device is
supplied with power (PowerGood), an error is detected, that ensures that the safety circuit is opened. The over-
ride input also functions in the event of a power failure, since this function is supplied by the emergency power
battery. If override is not active, the input must be high impedance.
Interfaces
18 SA3-SInstallation&CommissioningManual
Attention: The car must not be moved if the solenoid is deenergised, since the safety brake is then active. The
emergency release should remain locked until the override is active.
InMotion (A-6):
The input is used to signal to the safety device that the car is to be moved by the control system. It is needed
for testing the solenoid. In addition, the solenoid deenergises if the car is at a standstill with closed doors (not
"InMotion").
This measure serves to save wear and tear on the solenoid and helps to reduce the stand-by losses. The refe-
rence potential is GND (A-5)
Reset (A-7):
An error state can be reset via this input (see chapter "Behaviour in case of errors").
Position output (B-1, B-2, B-5, B-6)
The control system can be supplied with an incremental position signal via the position output. The reference
potential is GND (A-5)
Display module (B-4, B-8):
An external display module can be connected via this output. It has the same display as the internal display. The
internal 7-segment display on the remote display module is duplicated.

5.3 Connection to the safety circuit
As already explained above (see chapter „circuit types “), there are four possibilities to integrate the system in
the safety circuit of installation.
The system can be delivered for various voltage types of safety circuit (AC and DC). The standard version is
230V/50Hz.
Terminal assignment of signals from the safety circuit:
SA3-S Wire Signal
C-1 1 Door simulation (input, door relay)
C-2 2 Input N-wire (AC) or GND (DC)
C-3 3 Door simulation (output, door relay)
C-4 4 Earth
C-5 5 Earth
C-6 6 Door safety circuit (door input)
D-1 7 Safety circuit relay (input, scct relay)
D-2 8 Output N-wire (AC) or GND (DC)
D-3 9 Safety circuit relay (output, scct relay)
D-4 10 Earth
D-5 11 Safety circuit (scct input)
D-6 PE Earth
Table 5: Pin assignments for the safety circuit
In general:
› The safety circuit must be opened at the input C-6, if the car door or a shaft door is opened.
› The N-wire (the GND wire) of safety circuit must be led over the safety device.
The separation of N-wire connection must cause deactivating of the main contactor!
› The auxiliary control can bypass the safety circuit with a force-guided contact. Bypassing is required to free
trapped passengers.

Variante 1:
Auftrennung des Sicherheitskreises
disruption of safety circuit
Figure 5: Modication of the safety circuit (variant 1)
Explanation of the wiring diagram:
› The safety circuit is interrupted at the end of the series connection of the door contacts. The door contacts are
connected to input C-6.
› With the aid of the door relay, the safety device ensures that the safety circuit is closed if all doors are closed.
For this purpose, the start of the door series connection must be connected to input C-1, and the end (after
interruption) must be connected to C-3.
› The safety circuit input D-5 should be connected to the end of the safety circuit. It is responsible, among other
things for the detection of the loss of traction, i.e., if the a safety circuit is open but the car is still moving or is not
braked, it is „force-braked“.
› The relay of safety circuit can be looped in at any point in the safety circuit. It opens in case of an error (e.g.,
A3 detection) and is closed again by resetting the error. The safety circuit relay is not bypassed by override.
To release persons by means of auxiliary mode control, it must be placed at a point in the safety circuit that is
bypassed by auxiliary mode. The safety circuit relay is opened every 24 hours for a short time. This is neces-
sary to guarantee the proper operation of the relay.
Attention! During simultaneous use of override and the auxiliary control make sure that all shaft and car doors
are closed.
