CONTROL UNIT CUE Rev. A MC Date: 030224
INTRODUCTION
The control unit CUE is the heart of the preventive protection system controlling and
operating all the different functions. The control unit receives and evaluates information
from each detector and activates appropriate output according to the programme, such
procedures as activation of relays, solenoid valves, explosive outputs and/or text messages.
The control unit CU-E has an integrated power supply as well as a battery back-up. Each
control unit may be installed close to the respective risk area that is being protected thus
minimizing installation and maintenance costs. The control unit is equipped for connection
to a network. Up to 31 units can be connected in a network controlled by one master unit
MUE.
The control unit CUE consists of six main components.

FUNCTION
1. Power Supply Unit with battery backup.
The control unit is supplied with AC-voltage from the mains which is transformed to
the required voltages for operating the different systems and for charging the battery.
If the main supply drops out, the control unit will automatically switch over to
battery back-up, thereby maintaining the full functionality of the central unit. When
the main switch is re-established, the control unit will automatically return to normal
AC operation, and the battery will be recharged.
2. Monitoring.
The control unit checks all the connected components with regard to electrical
operation and the internal function of hardware and software. In the case when a
fault alarm is activated the operator receives a message on the LCD-display
clarifying the type of fault.
3. Control system with pre-programmed functions..
For any detector indication or any other input signal, programmed procedures will
immediately take place. These procedures can vary depending on different factors
for example energy level, number of glows or sparks, indications from several
detectors or other input signals.
4. Electronic log-book
The control unit stores events and alarms in the electronic memory, which can be
recalled by the operator on demand.
INSTALLATION
The control unit is shipped ready for immediate installation complete with lockable
enclosure, mounting brackets and cable glands. This items are located under the "flap" in
the box (Note: The delivered mounting brackets and screws should be used). Choice of
cable entry will be determinated by the terminal connections to be used. The control unit
should be located in a well protected area. If the CU-E is located out-doors it must have
adequate weather protection.

CONTROL UNIT CUE Rev. A MC Date: 030224
ELECTRICAL INSTALLATION
1. Power supply
The main connection to the control unit should be individually fused.
2. Installation of cables
All cables to and from the control unit should be installed in the same way as signal
cables in general. The network cables should be installed at least 300 mm away from
the power cables or other source of main disturbance. The network cables must not
be spliced. If there is a risk for cable damage a mechanical protection shall be
provided.
3. Process earthing
It shall be preformed according to standard: XXXXXXXXx
MECHANICAL INSTALLATION
Follow the given instructions in the project documentation. The location of detectors and
extinguishing zones is essential for the correct function of the system.
FIREFLY AB CAN NOT HOLD RESPONSIBLE IF THE INSTALLATION IS NOT
PREFORMED ACCORDING TO THE DRAWINGS ISSUED BY FIREFLY AB.
START UP
Connect the control unit according to the instructions and connecting diagrams issued by
FIREFLY. When all connections have been completed,
turn on the switch SW1:
and SW3:
For switches location see the layout at the end of the manual.
Check if the system gives any malfunction alarms. Check out any reiterated alarms and
make corrections accordingly. Make a function test for all equipment connected and test
outgoing alarms from the control unit (process interlocking control).

TEXT MESSAGES
*OPERATION STATUS MESSAGES
Normal operating conditions –Green LED ON
Test mode where outputs for solenoid valves and explosive release are active.
(Note: All relays are deactivated. Malfunction alarm is given by the malfunction relay
while
the system is in this mode). This test mode is used when testing extinguishing functions.
Test mode where all outputs are deactivated. (Note: All relays are deactivated. Malfunction
alarm is given by the malfunction relay while the system is in this mode.) This test mode is
used when the system should not be in operation, i.e. during maintenance work or when the
process is taken out of operation. This test mode can also be used for testing the system.
*MALFUNCTION MESSAGES
Cause : Incoming supply voltage is missing.
Trouble-Shooting: Check incoming voltage. If supply voltage is correct
the fuses F1 and F2 in the control unit must be checked.
Action: Solve the problem in a suitable way. Replace the fuses.
Cause: Internal voltage is faulty
Trouble-Shooting: Check that no cables are disconnected or that something may
have caused a short-circuit.
Action: Solve the problem or contact Firefly AB.

CONTROL UNIT CUE Rev. A MC Date: 030224
Cause: Broken electrical circuit or faulty battery.
Trouble-Shooting Check that the battery cables are connected and that the batteries
are functioning.
Action: Connect the battery cables. Replace the faulty battery with a new
one.
Cause: Broken electrical circuit between control unit and solenoid
valve
Trouble-Shooting: Check that the cable connector on the solenoid valve is
correctly connected and that there is no damage on the
cable.
Action: Fasten the cable connector or change the cable.
Cause: No contact between control unit and detector No. 1
Trouble-Shooting: Check that the detector is connected in the control unit.
Check that the plug-in cable to the detector is connected to
the detector.
Check that the detector cable is correctly connected to the
control unit.
Check that no cable is damaged.
Action: Connect the detector.
Connect the cable
Correct connection.
Change to new cable.
Cause: Detector of incorrect type is connected to input D1.
Trouble-Shooting: Check in the project documentation which type of detector
should be connected.
Action: Install correct type of detector.

CONTROL UNIT CUE Rev. A MC Date: 030224
Cause: Sensitivity of the detector connected to input D1 is not
Corresponding to the configuration in the control unit.
Trouble-Shooting: Check in the project documentation which sensitivity the
Detector should have.
Action: Change to correct sensitivity.
Cause: The temperature in the detector enclosure has exceeded the
preset temperature limit. The overheating can be caused by
to high temperature in the process or external factors, as
for example heat sources.
Trouble-Shooting: Find the cause for overheating.
Action: If the overheating is caused by the process, contact
FIREFLY for advice
Cause: Humidity in the detector enclosure.
Trouble-Shooting: If the detector is equipped with cooling air check the
instrument air quality.
Action: Dry the unit immediately. Use a cloth or similar for drying
the detector enclosure and the sensor cover. Blow the
electronics dry and clean by using instrument air.
Note: Do not dry the sensor wi
th hot air. The sensor
elements will be damaged if the temperature exceed 60?C.
Cause: The loop for explosive 1 faulty or not activated.
Trouble-Shooting: Check that the explosive output 1 is activated. See menu
EXPLOSIVE OUTPUTS. Check if the explosive loop is
faulty. (short circuits, broken circuits, and used or faulty
protractors.)
Action: Activate explosive output X by using menu EXPLOSIVE
OUTPUTS. Solve the problem in a suitable way.

Cause: The circuit supervised by input sensor 1 is not in it's normal
position (normally open or closed).
Trouble-Shooting: Check the documentation for normal function of the circuit.
Also check all items connected to the input.
Action: Rectify the error.
Cause: Incorrect main program.
Trouble-Shooting: Contact FIREFLY AB.
Action: According to FIREFLY AB’s instructions.

*ACTIVITY MESSAGES
Cause: Explosive output 1 has been activated.
Action: Reset the alarm with key for "reset".
Cause: The system has exceeded any of the presets criteria and
has therefore activated process stop.
Action: Find the cause for process stop and take necessary action.
Thereafter follow the routines that must be carried out after
process stop.
Cause:
Detector X has indicated a glowing particle. The energy
level was measured by the detector to be Y. The energy
level from a glowing particle is measured on a scale from
1-8, where 1 is the lowest and 8 is the highest energy.
Action: The message is for information only. The system has
carried out the pre-programmed procedures automatically.
