Alarm LED
When
there is an alarm that has not been acknowledged this LEDs will flash. If the alarm has
been
ac
knowledgedbut the condition still exists, the LEDs will remain on.
The
Alarm LED and the Remote Contact will be triggered when:
▪On Supply 1 when priority is Supply 2
▪On Supply 2 when priority is Supply 1
▪Not in Synchronism
▪Supply 1 or Supply 2 are not in spec.
▪There is/was an overcurrent/overload/load fault condition or Overtemperature condition
▪There has been a thyristor/SCR Fault
▪The Auto retransfer to preferred source has locked out & max number of automatic re-transfers
has been exceeded.

Alarm Cancellation Button
Pressing
this button acknowledges new alarms, causing the audible alarm to turn off and the LEDs to
go
from
flashing to solid.
5
Preferred Indicator
These
three LEDs indicate which supply is selected as the preferred supply. Supply 1 ‘I’, Supply 2 ‘II’
or
neither
may be selected.
6
Preferred Button
Pressing
this button repeatedly will scroll through which supply is selected as the preferred supply.
7
Supply 1 Okay LED
Green/Red
indicated that Supply 1 is within/out of tolerance. If fuse is open or blown or there is
no
power
present the power available LED will be Red.
8
Supply 2 Okay LED
Green/Red
indicated that Supply 2 is within/out of tolerance. If fuse is open or blown or there is
no
power
present the power available LED will be Red.
9
Sync Okay LED
Green/Red
indicated whether Supply 1 and Supply 2 are within/not within enough degrees
of
synchronisation
of each other to perform a transparent transfer.
10
On Supply 1 LED
Green/Red
indicates the load is on/not on Supply 1.
11
On Supply 2 LED
Green/Red
indicates the load is on/not on Supply 2.
12
Supply 2 Input
Push
-
in terminal suits 4mm² cable, use a small blade type screwdriver in the top slot and press in; insert the
cable and release.
Repeat for the Neutral Conductor. Note the neutral is not fused. Bare the wire just 8mm.
13
Output Okay LED
Green/Red
indicated the output is OK/faulty.
14
Load LEDs
There
are eight LEDs, the bottom six are Green and indicate roughly 10% - 90% loaded. The seventh
LED
is
orange and indicates 100% loaded. The eighth LED is Red and indicates that the iSTS is over loaded.
15
Remote Contact
Voltage
free alarm for integration into BMS. Do not connect any more than 50V/0.5A, not suitable
for
230
VAC. Contacts are Normally Closed. Contact is held Open when there is no alarm. When power
fails
the
relay contact closes (fail safe). The Remote Contact and the Red Alarm LED are driven by the
same
logic

A. INSTALLATION
a.
The Model R is a 2 pole, single phase DIN Rail mount STS that suits 35mm x 7.5mm rail.
b.
The STS is powered from two separate sources. All precautions to guarantee people’s safety shall be undertaken.
c.
The iSTS R is supplied with 2 DIN rail mounted fuse disconnectors (10x38 aR -20A) placed near the unit
with
sufficient space for cooling. The iSTS and fuses can only be mounted vertically.
d.
Incoming source should be terminated to the fused switch disconnector and then to the STS active inputs.
The
neutrals are not fused and should be terminated directly to the iSTS inputs. Ensure the cables are
securely
connected and supported.
B. SETUP
a.
Ensure that the two input sources are within tolerance, and that they are in synchronism (±15%of rated
voltage,
<10% THD, <15º phase difference)
b.
Connect your critical load to the OUTPUT. NOTE: Due to the nature of Silicone Controlled Rectifiers (SCRs),
some
load (~0.2A) is required for correct operation.
c.
Connect the sources to SUPPLY 1 and SUPPLY 2. If you wish to Confirm Operation you will need to be able
to
switch both sources on and off.
C. STARTUP
a.
Apply power to both input sources.
b.
There will be a short (15 sec) start-up period, after which the iSTS will begin powering your load.
c.
Confirm that the load is receiving power.
d.
Ensure that LEDs are correctly representing the supply status and load. NOTE: Only On Supply 1 LED or On
Supply
2 LED should be Red.
D. CONFIRM
a.
Use the Preferred Button to highlight ‘I’on the Preferred Indicator. Wait for the On Supply 1 LED to turn green
(if
is not already).
b.
Turn OFF Supply 1, and confirm that the iSTS transfers to ‘II’(On Supply 2 LED - green).
c.
Turn ON Supply 1, and confirm that the iSTS auto transfers to Supply 1 after a 3 second delay (On Supply 1 LED
-
green).
d.
Use the Preferred Button to highlight ‘II’. Wait for the iSTS to transfer to Supply 2 (On Supply 2 LED - green).
e.
Turn OFF Supply 2, and confirm that the iSTS transfers to Supply 1 (On Supply 1 LED - green).
f.
Turn ON Supply 2, and confirm that the iSTS auto transfers to Supply 2 after a 3 second delay (On Supply 1 LED
-
green).
