PD0009 V1.0 – 22 Jan 2016 5
The following parts are considered to be subject to normal
wear and tear, and as such are not covered by warranty
• Scratches and other visual damage to front panel
Voltages;
The SCS Connect controller must only be connected to
power supplies which comply with the acceptable voltage
ranges specified in the “Technical Specification” section of
this manual. Connection to supply voltages outside of these
ranges can damage electrical circuits, leading to premature
failure, and may cause the SCS Connect controller to
become unsafe. All SCS Connect controller’s ship from the
factory with voltage limits enabled. Disabling this protection
invalidates any warranty due to incorrect voltages.
Maximum voltages are logged by the SCS Connect controller.
Voltage fluctuations and surges;
SCS Connect controller has surge protection as specified
in the “Technical Specification” section of this manual.
Exposure to surge voltages outside these limits, or
excessively repeated surges within these limits,may cause
damage to electrical circuits, leading to premature failure.
Failure due to excessive surge voltages is not covered by
warranty.
Currents;
SCS Connect controller outputs should not be connected to
short circuits or to loads which exceed the currents specified
in the “Technical Specification” section of this manual.
Doing so may cause the controller to fail prematurely or
immediately, and possibly to damage the connected load.
Connection to incorrect loads voids the warranty.
Phase and relay terminals may carry currents high enough
to overheat cable terminations, if these are not correctly
specified and crimped. This may cause risk of electrocution
or fire. Care must be taken to ensure that cables and
terminations are safely terminated.
Segregation of power and signal cabling;
Correct segregation of power and signal cabling must be
followed. Do not run power and signal cables together in
the same conduit. Induction from power cables may corrupt
data signals, leading to incorrect operation.
Consequential failures;
SCS Connect controller includes features to protect both
itself and connected components in the event of a failure.
However failure of connected components may cause
damage to the SCS Connect controller, and failure of the
SCS Connect controller may cause damage to connected
components. Critical or vulnerable components should
be protected independently against failure. SCS Connect
controller is not warranted against damage caused by or to
other components.

Fault
Code
Fault Possible Causes and Actions
1
Door Open
The door has been left open
Closing the door will clear this fault. The door may not be
close properly due to sagging, and may require adjustment.
15
Excessive Condenser Overtemp
The condenser has seen multiple
overtemperature conditions in a short space
of time.
Check that nothing is blocking the condenser e.g. boxes, and
then reset by power cycling. If this fault continues to happen,
check that the condenser fan is functioning correctly.
17
NTC Failure
Either the main temperature sensor probe or
the condenser temperature probe (if fitted)
has failed.
The temperature probe needs replacing. The system will not
run while this fault is present.
19
Refrigeration Failure
The compressor has run continuously for the
configured time without reaching the setpint
temperature
Multiple possibilities, preventing the system from acheiving
temperature.
The system will not reset by power cycling, only by writing to
the “Clear Terminal Alarm” parameter (see page 31)
20
Return Air Under Temp
The temperature has dropped below the
normal mode setpoint by a specified amount
The product temperature keeps getting colder, even when
the compressor is turned off. Check the compressor is
correctly wired, and that the “Compressor State” parameter
is set correctly. Can also be due to an external secondary
compressor relay failure. (See page 31)
21
Triac S1 Overcurrent
The loading on S1 draws too much current
A high current components, such as the compressor, has
incorrectly been connected to the S1 output. Check the
wiring.
22
Triac S2 Overcurrent
The loading on S1 draws too much current
A high current components, such as the compressor, has
incorrectly been connected to the S1 output. Check the
wiring.
Reporting an alarm early will minimise the down time of
the cooler. An alarm code should always be supplied when
reporting an alarm.
32. Event Message Actions
Condenser High Temp
The condensor sensor is seeing a high condensor
temperature
High Voltage
The supply voltage is too high to turn on.
- Check supply levels
- Check the High Voltage Limit settings
Under Voltage
The supply voltage is too Low to turn on.
- Check supply levels
- Check the Low Voltage Limit settings
Door Switch Failed
The door sensor has been seen as open for a
long time, and is assumed to have failed.
- Check the door switch wiring
- Check the door switch operates correctly
- Chcek the Door Switch State parameter is set
correctly
Excessive Door Openings
The door sensor has seen a very large number of
door openings in a very short period of time
- Check the door switch wiring
- Check the door is closing properly
Faults can only be identified by connecting to the controller through bluetooth via the “Field”
App. All faults are logged in the events list, and visible by selecting the yellow triangular fault
symbol in the top menu bar (next to the Main Menu button)

The Wellington SCS Connect App provides a wireless
connection to the SCS Connect controller from mobile devices
fitted with Bluetooth® LE. This gives users and technicians an
unprecedented level of visibility, control and diagnostic tools
to optimise the controller’s performance and to troubleshoot
any problems. The following guide provides an overview of
the app and its capabilities.
Note: Screen shots shown are indicative only. Different
devices have different screen ratios, sizes and resolutions. The
actual image seen on your device may vary from the screen
shots shown in this guide. Holding your device in portrait or
landscape mode may have an effect on appearance and may
change how the various windows and graphics are displayed
and arranged on your screen.
37. Your 9-digit
touch panel
code
Download and install the Connect Field
app from Google Play (Search for “scs
wellington” to find it)
When you first run “Connect Field”, you will
be requested to enter an activation code.
Contact your User Manager or Wellington
to receive your activation code (You must
be connected to the internet at the time of
activation).
Note:
Your activation code is unique to you, and should NEVER be shared with anyone else, as it
determines your personal access level for the app. The same code will give you access to all
SCS apps you are authorised to use.
Once activation is complete, you must
define a 4-digit PIN code. This can be any
code unique to you. Each time you start
the app, you will be required to enter this
same PIN code. This is to prevent other
people accessing the app from unlocked
phones.
You can see which companies you are
activated against from the “Settings” screen.
You can be activated to more than one
company at the same time. Simply select
“ACTIVATE ANOTHER COMPANY”, and enter
the new companies unique activation code,
as in Step 2.

The Desktop App is intended for OEM’s and manufacturers. It
supports easy creation, checking and saving of parameter files
for Lab and Production use:
• Requires a Blue-Giga USB dongle to support BT-LE
• Uses the same activation code as for all other apps
• Connects to the controller in the same way as the mobile app
• Basic 4-screen interface (no hidden menus)
- Diagnostics
- Edit Parameters
- Asset Info
- Firmware Update
†† Due to the poor handling
of Bluetooth LE by Windows,
use of the desktop app on
Windows computers requires
an external Bluetooth device
(“dongle”).
†† The supported dongle is
Blue-Giga model BLED112,
available from Blue-Giga
stockists or from Wellington.
