DRS Introduction
The DRS can monitor up to twenty four separate external circuits and features:-
ۥ Twenty-four inputs in six groups of four.
€‚ Inputs suitable for 12V, 24V, Open Collector and Volt Free
operation.
€ƒ Mains and DC operation.
€„ Common fault output.
Front panel indicators confirm the current status of the connected inputs whilst the
comprehensive diagnostics ease external input and DRS testing.
It is used in conjunction with SID or JNR as part of an IEC 60849 compliant system to
monitor:-
€… Status of external UPS.
۠ DSP watchdog outputs.
€‡ External relay & alarm circuits.
€ˆ Third party, non-networked VA equipment.
A windows based software utility is available for use with the unit allowing simple
system configuration and adjustments. The software allows unit identification,
selection of monitoring type, configuration of the inputs and common fault output
as well as monitoring of mains & DC supplies.

Functionality
Front Panel Controls [See Appendix A]
Front panel controls allow configuration of the unit and LED’s display the current
status of each individual circuit.
The Rx and Tx leds flash to confirm fibre communications.
The PRI and SEC leds indicate a fibre fault
The OK led flashes when any new fault is detected on the
inputs, the units power sources or fibres and the common
fault relay is de-energised.
Press the OK button and the led will illuminate continuously
and the common fault relay is energised. I.e. OK= local fault
acknowledge. When all faults are cleared the led goes out.
The 9 pin D socket is for configuring the unit using the
supplied software. Refer to Appendix B for connection and
software details.
The Diagnostics section is used to
test the units operation as well as
derive additional information on the
connected inputs.
Refer to appendix A for full details.

Inputs indicators are split into six groups, each representing a single input socket
on the rear panel. The group name box is sized to allow the use of standard
adhesive labels for ease of user identification.
During normal operation the input leds will be off when no fault is present. They
will flash when a new fault occurs on the input with this changing to a steady ON
state if the local OK button is pressed. When flashing the Common Fault relay is
de-energised.

Appendix A
Unit and Input Diagnostics
The front panel Diagnostics section allows the verification of the units and any
connected inputs status.
The INPUT switch cycles through display modes;-
NORM =Normal The unit is in normal operating mode.
PWR =Power This displays the mains and battery input status on the
adjacent test leds. T2 indicates that the mains input is
OK and T3 that the battery input is OK.
RAW =Raw Data Allows the selection of one of three test modes
selected by the TEST button that cycles the mode
between T1, T2 and T3 as indicated by the leds above
the Test button. See below for further explanation.
TEST This display mode can only be entered into by the
simultaneous pressing of both the TEST and the
INPUTS button whilst in the RAW mode. See below for
additional information.

RAW DATA
The individual channel status leds are software derived and can therefore be
configured by the configuration utility to be either on or off when a fault condition
exists.
Often to save power and enable rapid location of a fault the system is configured
to only illuminate a led if the channel is in a fault state, this is totally independent
of the network reporting of the fault. In some cases the system specification
requires the opposite with indicators always on when OK and off when a fault.
Whist both are accommodated within the DRS software it is often useful to be
able to view the actual state of inputs both to assist initial set-up and subsequent
fault finding.
Press the INPUTS button to cycle to RAW.
Now press the TEST button to cycle through the three test modes.
MODE LED FUNCTION
1T1 Each channel led shows the real (raw) state of the
input. If the opto isolator is ON (volts present or
contact grounded) the channel led is ON.
2T2 Shows which inputs are active, i.e. set-up for use
using the configuration utility. If the led is on, its in use.
3T3 Rescans the inputs and shows all current input faults.
TEST Mode
To get to test mode select RAW mode using the INPUTS button and then press
and hold TEST switch. Whilst pressing also press the INPUTS switch, then
release both switches.
Pressing the INPUTS switch without the test switch will cause the DRS to skip
the test mode and go back to normal mode.
Once in test mode all fault monitoring is disabled and the common fault relay is
on. All network reported faults are cleared.

Appendix C
Input Description
The DRS has six sets of four opto-isolated inputs for monitoring external events.
When the DRS is networked to either a SID or JNR the events can be registered
on an LCD display. All logged faults can then be printed or stored to a log file on
a PC.
Each input channel can be configured for an external input of 12V DC or 24V DC
or can use the internal 12V DC power supply to allow external volt free or Open
Collector connections to ground to be used.
Connectors
Each group of four inputs is provided with a 15-Pin female Dee-type connector.

N.B. If an external supply or active drive is used, careful attention must be taken
over ground routing.
Configuration
Each input can be configured to operate in three modes :-
‰Disabled.
‰Fault when opto off.
Fault reported when opto-coupler diode is un-powered and
input OK when powered. This is the recommended mode of
operation as a break in the wiring between the contact and
the input will be reported as a fault.
‰Fault when opto on.
Inverse of above.
The status of these inputs is not latched, each input can be assigned an
individual name for easy fault recognition.
Configuration is carried out using the SID/JNR Utility available from Ikon AVS
Ltd.

Ikon AVS ltd DRS V1.00

SID/ JNR DRS Settings
When running the utility and having added a DRS to the configuration, it can set
up as follows.
Setting selector
Selects which section of the DRS configuration is displayed and available for
editing.
Event input settings
Displays the operating mode and details of each event input. These are
€Š Name. This is name that SID/JNR will display for this event input in any
event reporting.
Advise. Keep to 16 characters max for JNR and 20 characters for SID.
€‹ Active. When checked the event input will be used by the fault
monitoring system. When unchecked the input is excluded from the
fault reporting.
€Œ Fault On/Off. When On is selected the system will report a fault when
then event input opto is powered. When Off is selected the fault
condition is reported when the event opto is unpowered.

Appendix E
Power Supply
230V 50Hz, the mains fuse (T500mA 20mm ) is mounted within this connector.
The fuse carrier also contains a spare fuse. To reduce the risk of fire replace the
mains fuse only with the same type.
DC power inlet
In the case of a mains supply failure the supply (24V+/-1V @1A) provided via this
connector will be used instead. The plug is a standard D.C. connector with
2.5mm internal diameter, 5.5mm external and 14mm long. The central pin is the
positive connection. The status of the D.C. input can be included in the fault
monitoring.
