Hardware

2 Functions of the GST-XT

2.1 Hardware
The GST-XT group circuit board is a traffic control computer for FST-Controllers manufactured by NEW LIFT.
It enables the interconnection of individual FST-Controllers into a group. The GST-XT group circuit board is
suitable for the use of controller models FST(-1), FST-2, FST-2XT and FST-2s. When converting older group
controllers of the FST product family, the current software of the FST-Controllers is mandatory.
The GST-XT group circuit board is located in a separate housing in one of the control cabinets of the group
members. Installation takes place on a TS35 rail. A separate 24VDC voltage supply (switching power supply)
supplies the GST-XT independent of the FST group members and is, thus, separate from their voltage supply.
For processing the group control algorithms, the GST-XT has a 32-bit processor as well as a Neuron processor,
which is responsible for the LON activities.
The GST-XT is equipped with a serial interface that offers all lifts of the group a central modem or fax connec-
tion possibility. The RS232 serial interface of the GST-XT enables the connection of a PC to the lift group for
monitoring and remote control by means of the ELEVISION lift monitoring software as well as the connection of
a fax modem or a protocol adapter module (PAM) for evacuation controllers.
Depending on the number of BUS members of the shaft bus, it may be necessary to use a power repeater. This
galvanically isolates the BUS modules from the GST-XT or FST and amplifies the supply voltage as well as the
data signals.
The integrated SD card interface enables recordings, which are useful for traffic analysis. Should it be neces-
sary to update the GST-XT software, a USB connection is available for convenient updates by means of a USB
stick (optional).

2.2 LON technology

All electronic assemblies of the FST are based on local operating network technology, abbreviated LON-tech-
nology. This open network technology is used, in particular, in building automation.
Communication is via a serial bus, the so-called LON bus. The processor assembly of the FST main circuit
board coordinates all data traffic of the lift system from the control cabinet.
The LON bus is looped through from electronic assembly to electronic assembly with pre-assembled, four-core
cables. External data exchange is subject to the standardised protocols of the LonMark standard.

2.3 Operating principle of the GST-XT

The GST-XT group circuit board likewise makes optimised use of LON technology, which is implemented in
the FST-Controllers. By means of this technology, the GST-XT becomes aware of all activities on the LON bus
and, thus, of all measured and actual characteristics of all lift systems participating in group mode. Thanks to its
32-bit computing power, the GST-XT can intelligently process this information and thereby ensure efficient traffic
management of all group members.
A mixture of automatic and configurable functions lends the GST-XT a unique level of flexibility, even for the
most demanding installations.
The incoming calls for the shaft bus are processed further by the GST-XT and calculated taking into account a
number of criteria of the group algorithm. Based on this group algorithm, the GST-XT then distributes the calls
to the individual FST-Controllers within the group.
In the unlikely event of a GST-XT failure, an emergency program within each FST-Controller takes over the
drive commands. For installations that require a high level of readiness, a multiple-redundant group controller
option can be integrated by mounting at least two GST-XT group circuit boards within the group. In the event of
a system failure of the primary GST-XT, one of the secondary GST-XT takes over the group controller function.

GST-XT manual 7
Functions of the GST-XT
Operating principle of the GST-XT

Stored in the GST-XT memory are copies of the parameter sets of all connected FST-Controllers. In this way,
the GST-XT can include information about door times, drive curves, drive calibration data and shaft dimensions
of the individual controllers in the group algorithm.
If control parameters are changed in one of the FST menus, this is automatically detected by the GST-XT and a
copy of the changed parameter set stored in memory.
Should it be necessary to change date and time settings on a controller, all controllers of the group accept the
new time settings in synch.

Technical details and data

3 Technical data
The GST-XT consists of an FST and the GST-XT group circuit board, which is installed in a separate housing.
Power for the GST-XT, as well as the shaft bus and its members, is supplied by means of an external 24VDC
mains device. As a result, the GST-XT remains switched on even after the FST is switched off. Not until the
shaft bus input (F6) is switched off is the GST-XT de-energised.

6 GST-XT commissioning

6.1 General
On delivery, the GST-XT-Controller is preconfigured to your specific requirements. Commissioning the GST-
XT-Controller therefore only involves setting (checking) a few parameters and performing a few simple tests to
check the group function. The GST-XT-Controller is not commissioned until after all FST-2-Controllers participat-
ing in group mode have been commissioned. The following requirements must be met for all lifts participating in
group mode prior to commissioning of the GST-XT-Controller:
››Fully commissioned shaft positioning (calibration drive successfully completed)
››All landing call modules are connected to the appropriate control cabinets as per the bus plan
››Enabled and functional landing control
››Establish LON BUS cable connection between GST-XT and FST. See bus diagram.
››All shaft buses are functional, any necessary power repeaters (shaft or controller) are connected to LON BUS
according to bus diagram and to the supply voltage (see wiring diagram) and are ready for operation.
››Released and functional car doors (test menu)
All parameters mentioned in the following can be found in the FST and GST-XT menu. The GST-XT menu is
available on all FST-Controllers that participate in group mode.

6.2 Commissioning steps

The GST-XT-Controller is commissioned in the following steps

The bus connection plugs of the FST-Controllers may differ from the previous controller, FST(-1)! If nec-
essary, use the wiring diagrams to check this.

6.2.2 Establishing bus connections

To ensure communication of the FST-Controllers participating in group mode with the GST-XT-Controller,
the connection cables between the individual FST control cabinets must be plugged-in according to the bus
diagram.

Plugging-in bus cables

►►Have the wiring diagrams of each of the FST-Controllers participating in group mode at hand and open the
bus diagram (last page before the legend: "Bus topology")
►►Establish the cross connections between the FST control cabinets specified in the bus plan using the bus
cables intended for this purpose
►►Be certain to plug in terminators - designation "T" - according to bus diagram
Now switch on the FST-Controllers with controller fuse. Wait until the boot process of the FST-Controllers
has concluded and then continue with Chapter 6.2.3.

6.2.3 Checking basic settings in the FST-Controllers

The basic settings of all FST-Controllers participating in group mode are checked in the FST under:
››--FST INFORMATION--
››MAIN MENU / Configuration / Group Settings
››MAIN MENU / Calls / Call Floor

24 GST-XT manual
 GST-XT commissioning
Commissioning steps

Checking the lift ID-numbers

►►Simultaneously press +  ; --FST INFORMATION-- appears on the first line
►►Use the � button to scroll until the LiftID:appears
►►Note the ID number: ABCDEFGH

►►Press  to exit the FST information menu

►►Under MAIN MENU / Configuration / Group Settings / Lift ID-Number, compare the ID
number set here with the ID number noted previously
►►Both IDs must match
►►Repeat the procedure for all FST-Controllers participating in group mode.
Only change the IDs in consultation with the NEW LIFT service line!
All FST-Controllers participating in group mode must have a unique lift ID-number (FST A (No.0) ... FST H
(No.7)).

The lift ID-number must correspond to the jumper settings (see wiring diagram) of bus modules FSM
and FPM as well as the configuration of the landing call modules. If not observed, function of the FST-
Controllers cannot be guaranteed! Lift ID-numbers that are assigned twice lead to massive malfunctions
of the GST-XT- and FST-Controllers!

Activate all FSTs as group members

Select under MAIN MENU / Configuration / Group Settings / Group Member

►►Set with �/� YES and confirm with 

Setting offset properties

The group offset is the offset between the shafts of the FST-Controllers participating in group mode.
If the bottom floor of all FST-Controllers is the same physical floor of the building, the group offset = 0 (normal
case). If this is not the case, the group offset of the FST-Controller that travels to the bottom floor is to be set to
0; for the other FST-Controllers, the value is to be set so that it corresponds to the floor offset of the shafts.

Error-free function of the GST-XT controller board is ensured only if the group offset is set correctly.
In the event of uncertainties regarding the group offset, contact the NEW LIFT service line!

GST-XT commissioning
Commissioning steps

Setting offset properties

►►MAIN MENU / Configuration / Group Settings / Group Floor Offset.
►►Use � to set the group offset and confirm with .
►►Repeat the procedure for all FST-2-Controllers participating in group mode.
If one of the FST-Controllers has a group offset > 0, specify for this FST-Controller whether or not the set value
is to affect control of the floor position indicator and departure arrow. This occurs separately for the position
indicators in the car (flr offset-car) and on the floors (flr offset-landing).

Offset properties for position indicators car & landing

►►Select MAIN MENU / Configuration / Group Settings / Flr Offset-Car or Flr
Offset-Landing.
►►Use �/� to set YES or NO and confirm with .
►►Repeat the procedure for all FST-Controllers whose group offset is > 0.
How the group offset affects control of the floor position indicators and departure arrows is now set.

Correct function of the floor position indicators and departure arrows is only ensured if parameters Flr
Offset-Car/ Landing are set correctly.
In the event of uncertainties, contact the NEW LIFT service line.

Checking bus masks

The FST menu of each FST-Controller has two bus masks that define to which bus lines of the landing control
this FST-Controller responds (ADM-Bus Mask-1 and ADM-Bus Mask-2). Bus-Mask 1 defines to which landing
lines the FST-Controller responds in normal group mode. Bus-Mask 2 defines to which bus lines the FST-Con-
troller responds if individual lifts were separated from the group (e.g. by a programmable input/output).
The Bus-Mask 1/2 parameters are 8-bit registers with the following structure:

Bit 0: bus line 0 1 = FST responds to corresponding bus line

Bit 1: bus line 1 0 = FST does not respond to corresponding bus line
Bit 2 - 5: bus line 2 - 5
Bit 6: bus line 6
Bit 7: bus line 7

Fig. 6.4: Structure of the Bus-Mask 1 / 2 parameters

Adjust standard setting bus masks

►►Select MAIN MENU / Configuration / Group Settings / ADM-Bus Mask-1.
►►Select the individual figures with � � and adjust both figures to FF with �/� and confirm with .
►►Repeat the procedure for all FST-Controllers.

Normally, the value FF is set for both bus masks, i.e. calls from all bus lines can be sent to all participat-
ing FST-Controllers.
Only in special cases or if lifts are dynamically separated from the group is a setting other than FF necessary.
Proper function of the GST-XT controller boards is ensured only if the bus masks are properly set.
In the event of uncertainties, contact the NEW LIFT service line.

Following successful group function test, complete by confirming the parameters, i.e., according to Chapter
6.2.7:
►►MAIN MENU / GST MENU / Configuration / FST->GST auto-cfg
►►Select YES with � and confirm with .
The parameter sets of all connected FST-Controllers are now automatically transferred to the GST-XT controller
board via the LON bus. This procedure is indicated in the same way as "Loading FST parameters" via the LEDs
of the GST-XT and in the FST display.

Completing the check of the GST-XT basic settings

►►Now press the � button several times to exit the submenu or main menu of the FST.
►►If parameters were changed, the Save changed values? message appears, prompting for confirmation.
►► Use the � >YES<button if a change was knowingly made. Confirm selection by
pressing the  button. The standard display then appears as shown in, e.g., Chapter 4.2.

6.2.7 Testing group function

The function of the GST-XT-Controller is tested by actuating the landing call and observing the call acknowl-
edgement and the departure arrows and floor position indicators. This procedure must be repeated step-by-step
on all floors and access sides.

Testing landing calls

►►Actuate landing calls in both directions and observe the call acknowledgement.
The call acknowledgements of all landing calls (all bus lines) illuminate in both directions of travel.
One of the group lifts arrives on the floor and extinguishes all call acknowledgements in one direction of travel
(all bus lines).
►►Use a car call to send the lift that arrived in the direction of travel that was extinguished to a different floor
(ideally, one as far away as possible).
A second lift arrives at the floor and extinguishes the still-illuminated call acknowledgements (all bus lines).
►►Repeat the procedure on all floors.

Test departure arrows and chime

►►Actuate landing calls in both directions and observe the departure arrows.
One of the group lifts arrives at the floor and activates its departure arrow in the current direction of travel.
The arrival gong sounds.
After the car call priority time elapses, both departure arrows are activated.
►►Use a car call to send the lift to a different floor (ideally, one as far away as possible) and again actuate the
landing calls.
►►Repeat the procedure until the departure arrows and gongs of all group lifts have been activated once.
►►Repeat the procedure on all floors.

Completing the group function test of the FST-Controllers and GST-XT

►►See Chapter 6.2.6 "Automatically loading FST parameters"
The GST-XT-Controller is now commissioned.

Programmable inputs/outputs
General

8 Programmable inputs/outputs
The GST-XT-Controller has eight programmable inputs/outputs, which are located on plug X2. They are used
for the order-related definition of group-wide functions.

8.1 General
Characteristics of a programmable input/output:
››Assigned function
››Signal direction (input or output)
››Active level (+24 V or GND)

Function
Each input/output can be assigned a function via the GST-XT menu directly on-site.

Signal direction
The signal direction of the inputs/outputs is subdivided into input and output functions.

Level
The active level of the function can be defined with + 24V (normally closed function) or GND (normally open
function).

Input functions
The input function is triggered as soon as the state at the input/output changes from the inactive level to the
active level (normally open function: from +24V to GND, normally closed function: from GND to +24V).

Output functions
As soon as the condition of the output function is fulfilled, the state at the input/output switches from the inac-
tive level to the active level (normally open function: from +24V to GND, normally closed function: from GND to
+24V).

8.2 Programming
The inputs/outputs are programmed in the GST-XT menu via a hexadecimally encoded value that results from
the sum of a defined function code and individual option codes.
The setting is made under GST-Menu - Configuration - I/O-Programs in the so-called "raw register".

8.3 Setting the raw register

Each of the eight programmable inputs/outputs has a raw register. The raw register is an eight-digit hexadeci-
mal value by means of which the corresponding terminal can be assigned a function from the function table.
Furthermore, the active level, the signal direction and the function parameters are set in the raw register.

Fig.8.1 Function of the individual digits of the RAW register

Function table
The function table contains all functions that can be assigned to a raw register. The "Param." column specifies
whether or not the corresponding function has function parameters. If there are function parameters, these are
explained in a separate description. The "Raw" column shows two possibilities for the last two digits of the RAW
register. The one at the left corresponds to the "active low" level (normally open), the one at the right corre-
sponds to the "active high" level (normally closed). The setting is to be made according to the hardware wiring
of the terminal.

30 Special function (internal use) Yes Input ...F2/...F3
31 Floor locking Yes Input ...FA/...FB

8.4 Function "group division"

The function "group division" enables the dynamic splitting of individual lifts from the GST-XT group function;
these lifts then function as single lifts with their own landing control. Thus, a group of four can become a group
of three plus one single lift as soon as a switch is thrown.
Required for this function are multiple shaft buses that can be assigned to the individual lifts via parameter "bus
mask 2" (see FST manual).
