. SYSTEM OVERVIEW & OPERATION
2
.1 Description
A
Static Transfer Switch (STS) provides seamless switching between two power sources to provide
interrupted
power
to a critical load.
The
iSTS continuously monitors the supply sources for failure or degeneration and switches automatically to
the
alternate
source as required to protect the load against failure. The break in the supply transition is so short
that
it
is not seen by the critical load. This switching process is undertaken as a break before make
transfer,
preventing
overlapping which can cause large and unpredictable currents. In 4-pole models, all the
active
conductors
and the neutral are switched. In 3-pole models, only the active phases are switched. Thyristors
are
used
to undertake the switching process.
In
the case of downstream load fault conditions, the fault current drawn from the supply may degrade or
damage
the
supply sources; as a consequence should a fault current exist in the load the iSTS will inhibit a transfer to
the
alternate
source even if this causes source supply degradation or loss. This is to ensure that the fault will not
be
transferred
to the alternate supply with the possibility of degrading both sources.
The
current threshold for isolation is pre-set to approx. 300%of the rated current.
This
unit contains fuses. The fuses are to provide for safe operation even in high fault capacity environments.
It
should
be noted that the fuses are for the protection of the semiconductor switches (SCRs/ Thyristors), not
the
load
. The iSTS does not have any automatic tripping devices, so load discrimination is undertaken in the
primary
and
secondary supply networks.

.1 Safety
The
iSTS is powered from two separate sources. It is important that you install correct signage with
procedures
within
the enclosure and the immediate vicinity to warn personnel of this aspect and what isolation,
checking
and
precautionary processes, and procedures need to be adopted to make the iSTS and equipment
connected
to
the iSTS safe to work on.
This
equipment receives power from more than one source. Disconnect output and all input sources of
power
from
this equipment before servicing.
Do
not proceed with the installation or operation of the iSTS if it has been damaged. Carefully inspect the
iSTS
for
any damage that may have occurred during shipping, unpacking or during and after any
installation
process
.
Take
care when handling the iSTS and ensure that it is physically supported during the installation process.
At
the
end of the installation process the iSTS should be firmly and securely bolted within the rack.
Ensure
the cables are securely connected and supported and all covers plates are replaced. There should
be
NO
live exposed or accessible contacts that could cause electrical shock if contact is able to be made. This
unit
is
designed for fixed wiring installation only.
This
equipment is not suitable for installation into environments that utilise RCD earth leakage detectors
on
the
inputs of the static transfer switch. Consult Static Power for special considerations.
EARTH CONNECTION IS ESSENTIAL BEFORE WORKING ON CIRCUITS
OR CONNECTING / DISCONNECTING SUPPLIES.
TREAT AC INCOMING LEADS AS LIVE IF DISCONNECTING FROM SOURCE.

.3 Cable Termination to the iSTS
1. Attach cables using bolted lug connections to the terminals in the order show below. The terminals have
a
M6/M8 screw
2. To access the input and output terminals by removing the terminal cover and GAL plate from the front
of
the unit. Cables enter from the bottom. Remove the gland plate and make holes suitable for gland.
3. Connect Active, Neutral and Earth cables to the respective terminals as marked at the terminals.
Secure
the connections on the terminal blocks, torque the screw to 25Nm /20in-lbs. All cables connecting to
the
STS should be supported by the gland and not strain the point of connection.
4. All electrical connections are to be realized by properly qualified, skilled and competent service
personnel
only.
5. Open the door of the top enclosure and its GAL panel and check all connections and that all ribbon
cables
are plugged in and secure. That nothing has moved out of place during handling and transport. Check
all
screw connections.
6. Before applying power replace all of the GAL panels removed prior, close the doors and replace
the
termination enclosure cover. Check the ratings of all sources and cables to the iSTS, make sure that
the
rated voltage for the unit corresponds to the ratings plate and the local supply voltage.
7. Turn the maintenance bypass switch to the bypass position (either to S1 or S2). Closer the incoming
source
isolators. (Not the two incoming source isolators provide power to the solid-state portion of the STS
only.
The load will be powered via the maintenance bypass switch.
8. Apply power to the STS. After a few seconds the LED mimic will show the direction of power flow.

.4 Synchronism
The
smoothest change-over occurs when the supplies are in synchronism, so it is best to make sure the
input
supplies
are in synchronism. Some equipment (like transformers and other items) may saturate when a
transfer
occurs
when not in synchronism. This causes large currents to flow into the load which could cause damage
to
the
transformer, trip protective devices or blow fuses.
The
iSTS is configured to optimize the transfers. Manual transfers by default have uninterrupted
transfers,
however,
at greater phase displacements (up to ±180 degrees) a break of up to 12ms is inserted.
3
.5 Start-up
NOTE
: Due to the nature of SCRs (silicon controlled rectifiers) some load of around 0.5A is required for
correct
operation
. Before testing the operation of this iSTS, make sure this load is applied to the output.
1. Ensure that your two input sources are within the tolerances and in synchronism.
2. Once power availability has been confirmed slowly rotate the STS maintenance bypass switch to the
N
(Normal) position
3. Apply power to both input sources. There will be a short 15 second start-up period, after which the
iSTS
will begin powering your load.
4. We recommend at this point that you connect to the STS using a laptop computer. Open up a browser
and
make connection via the LAN. We strongly encourage the setting of the date and time so that real
time
event correlation can be undertaken. The Real Time Clock is backed up by a rechargeable coin cell
battery.
If the battery is flat at the time of commissioning it may take several days to re-charge.
5. The ALARM should not be active. If it is check the following conditions that may be active:
-ON Supply 1 when priority is Supply 2
-ON Supply 2 when priority is Supply 1
- Supply 1 or Supply 2 are not in spec
- Override Switch is in position 1 or 2
- Supply 1 & 2 are not in synchronism
- The unit is too hot (thermal bi-metal switch on H.S. activated)
- There is / was an overcurrent/ overload / load fault condition

.3 Preferred Switch
This
switch allows the preferred source to be set to Supply 1, Supply 2 or None (0), which will take affect
only
when
the preferred source is set to None (0) on the iSTS software. Refer to the Web Interface section
for
instructions
on changing the preferred source through LAN connectivity.
If
the iSTS has transferred the critical load to the alternate source, the iSTS will automatically transfer back to
the
preferred
again when the preferred source is within tolerance and after a pre-set settling delay, typically
4
seconds
.
4
.4 Override Switch
Setting
the override switch to 1or 2 will force the iSTS to stay on that supply even if faults are detected on
that
source
. This switch overrides all other settings. It should not be used to transfer the critical load between
sources
(a
break may result).
NOTE
: The override provides control logic bypass only, it does not provide an alternative path for the load power.
WARNING! The override switch initiates instantaneous transfers and may transfer faults to the load.
WARNING! Never attempt to operate the OVERRIDE switch if the supplies are not in synchronism. There is no
interlock to prevent the switch from being operated when the supplies are not available or not in
synchronism. Refer to the LCD variables display and mimic diagram to check the synchronism state, (SYNC LED
will be RED, variables display will show degrees out of synchronism. Only operate when less than 10 degrees).
If the control is not operating you may need to use other means to determine that the supplies are in
synchronism. Do not operate the OVERRIDE switch onto an absent supply.

. MAINTENANCE BYPASS
5
.1 Overview
Maintenance
Bypass mode allows the load to be connected to one supply without going through the
power
circuit
of the STS.
The
maintenance bypass switch is located on the front of the power module. The switch is normally in the
“N”
position
and can be used to bypass the internals of the STS to either “Supply Source 1”or “Supply Source 2”.
THE MAINTENANCE BYPASS SWITCH SHOULD ONLY BE USED TO SELECT THE PRESENTLY OPERATING SOURCE.
IT CANNOT BE USED TO TRANSFER THE CRITICAL LOAD FROM ONE SOURCE TO THE OTHER.
The maintenance bypass switch utilises make-before-break switching, incorrect operation of the
maintenance bypass features could result in dangerous voltages occurring and short circuits.
Note
: A padlock can be used to stop inadvertent or unauthorized operation of the switch.
5
.2 Maintenance Bypass Procedure
Bypass
Mode on Supply 1
1. Use the TRANSFER pushbutton on the front of the unit to transfer the load to Supply 1.
2. TURN OFF Supply 2 using the isolator switch on the front of the unit.
3. Finally operate the Maintenance Bypass Switch by turning to position 1. The unit will now be in
bypass
mode on Supply 1.
Bypass
Mode on Supply 2
1. Use the TRANSFER pushbutton on the front of the unit to transfer the load to Supply 2.
2. TURN OFF Supply 1 using the isolator switch on the front of the unit.
3. Finally operate the Maintenance Bypass by turning to position 2. The unit will now be in bypass mode
on
Supply 2.
Removing
the Power Module
Once
the unit is in maintenance bypass mode on either Supply 1 or 2, the unit can be tested as the output of
the
solid
-state switch is disconnected by the maintenance bypass switch. To service the switch and before
removing
the
internal Gal panel turn-off the isolators ion the terminal enclosure and remove the control fuses. This will
not
affect
power flow to the load when in maintenance bypass.

.3 Reinstatement from Maintenance Bypass
1. Turn on both Supply 1 and Supply 2 circuit breakers located at the front lower terminal section of the
unit.
Wait for the unit to start up. The mimic on the display screen should show Supply 1 and 2 as GREEN
to
indicate that both supplies are active in the STS.
2. Move or operate the Preferred Source selection switch to the supply that is in bypass.
3. Check the mimic LEDs and ensure that the STS and the maintenance bypass are the same (e.g.
if
Maintenance Bypass is at position 1 then the STS portion powering the load should have 1 Green)
4. Finally operate the bypass switch, returning it to the middle position.
5. The unit will now be normal operation mode.

. WEB BROWSER INTERFACE
Connecting
to the LAN interface can be done two different ways with a RJ45 Cat5 Ethernet cable:
▪To a Network hub/switch using a straight-through cable.
▪To aPC using a cross-over cable (most PCs can now work with a straight-though cable).
6
.1 Connection to a Network
By
default the STS uses s Static default IP address of 192.168.1.2, however, if required from the lan/
HTTP
interface
a DHCP can be selected to have the IP information assigned automatically after the Ethernet cable
is
plugged
in at both ends, this process can take up to several seconds to complete. If your network does not have
a
DHCP
server or if you wish to use a static IP, you can change the IP Allocation on the Communications
Settings
screen
shown below (or the Control Panel page on the Web server).
Use
the Settings/ Control menu, enter the User admin and the passcode 1234to access TCP/IP settings.
Setting
IP
Allocation to Static allows for manual input of IP address, subnet and gateway. If you have lost the IP
address
use
a suitable App to scan for the set IP address of the STS.
iSTS F3

6
.2 Connecting to aPC
When
connecting directly to a PC, both the STS and PC must have statically assigned IP addresses on the
same
subnet
. Set the IP address of the STS in the Communications screen described earlier. By default this is
IP:
192
.168.1.2 with Mask: 255.255.255.0
To
set the IP address of your computer in Windows 7/10 go to: Network and Sharing Centre Change
adapter
settings,
right-click the network interface Properties. Select TCP/IPv4 Properties. Change the values to

Set
Preferred
The
iSTS will stay connected to the preferred supply until there is a failure. In the case of the supply failing,
the
STS
will switch to the alternate supply and then switch back to the preferred after the fault has cleared and
the
incoming
AC voltage has returned to normal. When None is selected, the iSTS will not revert back to the
other
supply
after switching. Internal preferred setting should be on none for this to work correctly.
