MAN0966 04-15
Ensure that this Operating Manual is read and understood BEFORE installing / operating /
maintaining the equipment. Pay particular attention to Warnings and Cautions. All document
Warnings are listed here and repeated where appropriate at the start of the relevant chapter(s)
of this Operating Manual. Cautions appear in the sections/sub-sections of the document where
they apply.
WARNINGS
LeakFilm controllers and sensors are designed for installation and use in ordinary
areas only. Do not install the controllers and the sensors in hazardous areas.
Installation must be in accordance with the recognized standards of the
appropriate authority in the country concerned.
Access to the terminal block for wiring and switches for conguration of the
controller, when carrying out any work, must only be conducted by trained
personnel.
Before carrying out any work ensure local regulations and site procedures
are followed. Appropriate standards must be followed to maintain the overall
certications.
Never attempt to open a plastic enclosure or connector or replace/ret the wire of
the sensor while power is still applied to the controller.
LeakFilm controllers must be earthed/grounded for electrical safety and to limit the
effects of radio frequency interference. Earth/ground points are provided “F.G.” or
“SHIELD” terminal of the controllers.
Ensure that all screens/instrument earth/clean earth wiring is earthed/grounded
at a single point (either at the controller or master controller - BUT NOT BOTH)
to prevent false readings or alarms that may occur due to potential earth/ground
loops.
The plastic enclosure of the controllers is a potential electrostatic charging
hazard. Avoid any conditions that could result in the controllers becoming
electrostatically charged.
Take care when handling LeakFilm sensors as they may be damaged by sharp
tools.
LeakFilm controllers should be handled with care to avoid mechanical shock and
impact.
Do not expose to temperatures, humidity and other conditions beyond the storage
and operating ranges.
LeakFilm controllers must have a suitably rated fuse.
LeakFilm controllers and sensors should be installed in a location free from dust,
direct sunlight, temperature extreme, strong magnetic eld and heavy vibration.

4. Introduction
LeakFilm MC is a master controller to monitor the status of controllers connected to its
communication line. LeakFilm Pro, 5 and HC controllers can be connected to the
LeakFilm MC.
The controller features a buzzer, and 9 push buttons UP, DOWN, LEFT, RIGHT, ENTER,
MENU, RESET, ESC, SILENT for conguration. 4 LEDs indicate the status of fault, leak,
communication error and power and a 20x4 character LCD gives status indication and
conguration.
The master controller also provides 3 relays (fault, leak and communication error) for
controlling external equipment such as alarms, sirens, valves or switches.
LeakFilm MC has been designed to be mounted through 4 mounting holes, so that the user
can easily install the controller on a wall or in the interior of an electrical control panel.
Caution: LeakFilm Mini cannot be connected to LeakFilm MC because it does not
have the appropriate communication feature. LeakFilm 5 should be used instead
to connect to LeakFilm MC.

5. Installation
5.1 Mounting and Location
LeakFilm MC has been designed to be mounted through 4 mounting holes, so that the user
can easily install the controller on a wall or in the interior of an electrical control panel easily.
The following points should be noted when locating the controllers.
• When locating the controllers, consider the possible damage caused by natural events
e.g. rain or ooding. LeakFilm MC provides only IP43, limited water proof feature.
• Consider ease of access to the controller for repair and maintenance.
• Avoid any location mentioned in the above warnings.
See the installation drawing at the end of this manual for mechanical dimensions.

5. Installation
LeakFilm MC (master controller) can be connected to LeakFilm Pro, 5 and HC (slave
controllers) using RS-485 as shown in the above diagram. For LeakFilm Pro or HC
controllers, up to 200 units can be connected to the master controller while LeakFilm 5
is limited to 15 units. When the slave controllers communicate with the master controller,
each slave controller should have a unique ID. See the manual of each slave controller for
instructions on how to set the communication ID.
Caution: Each slave controller connected to LeakFilm MC should have a unique
communication ID, otherwise incorrect data can be transmitted to the master
controller.
Once the LeakFilm MC turns on, it starts to scan all IDs to check the slave controllers
connected to it. The user can determine the maximum ID number (MaxMD) of slave
controllers which is used for scanning from 1 to MaxMD. The acceptable range is 1 to 200
and the default value is 200. See “6.1 Electrical connections” for instructions on how to set
MaxMD.
When you use LeakFilm 5 together with LeakFilm Pro & HC, set the ID of LeakFilm 5
between 1 and 15 rst and then set the IDs for LeakFilm Pro and HC later to the rest of the
numbers, because LeakFilm 5 ID can be set only from 1 to 15 while LeakFilm Pro & HC can
be set from 1 to 200.
It takes around 20-25ms for the master controller to scan 1 slave controller, so it requires
at least 5 seconds (cycle time) to scan 200 slave controllers. If the cycle time is too long for
the application, the number of slave controllers connected to the master controller should
be limited. For example if the cycle time needs to be less than 1 second, a maximum of 40
slave controllers should be connected to one master controller.
Caution: Each slave controller connected to LeakFilm MC should have a unique
communication ID, otherwise incorrect data can be transmitted to the master
controller.
Caution: The number of slave controllers connected to the master controller should
be limited based on the required cycle time.
