1.0 Introduction
The LC Series Control Units that provide facilities to monitor a wide variety of industry standard environmental and other sensors.
The LC1 provides 1 monitoring channel.
The LC2 provides up to 2 monitoring channels.
The LC4 provides up to 4 monitoring channels.
The LC-Series Controller has been designed to allow the use of any ENMET sensor transmitter and has been preprogrammed to
match the sensor transmitters supplied at time of delivery. The LC-Series can also be used with any manufactures sensor transmitter
that can produce a voltage or current output within a specified range; however, it is advisable that you contact ENMET for proper
setup and programming instructions. Care has been taken with the design of the MCU housings and internal chassis to facilitate ease
of connection and wire termination. All on-site wiring to the system is via screw terminal connectors. The terminal cover has an
internal label giving details of the external connections.
NOTE:All specifications stated in this manual may change without notice.

3.0 Installation
The LC-Series Controller is fully tested prior to delivery. However, it is recommended that the LC-Series Controller system be
checked after installation is complete.
CAUTION: The MCU Control Units and associated modules contain no user serviceable parts. Refer all servicing to qualified
service personnel
The LC series control units must be mounted in a non-hazardous location where there is no risk of the presence of potentially
explosive gas
Either a 100-240VAC 50/60 Hz supply or a 24V DC supply can be used to power the control unit
The location of installation should be chosen with regard to the following:
This equipment should not be located near to known sources of heat.
Operating personnel should be within convenient reach of the equipment and within audible distance of alarms
Maximum loop lengths of cable run and cable inductance to resistance ratios must not exceed limits shown in the relevant
loop diagrams
Avoid mounting this equipment near potential sources of electrical interference e.g. motors, switch gear, radio transmitters etc.

4.0 Wiring the LC Series
The electrical installation should conform to appropriate electrical codes, such as the National Electrical Code in the United States.
WARNING:The compliance of the installation to appropriate codes is not ENMET’s responsibility.
4.1 System Wiring
All connections should be made according to the appropriate sensor or loop diagram for the configuration required. It is advised
that ‘Bootlace Ferrules’ or ‘flat blade crimps’ be used for tidy and reliable connections of wires into the Control Unit and Detector
Head connectors
Power Supply Input
An isolating switch should be provided between the power source and the MCU control units to allow the supply to be easily
disconnected. This should incorporate over current protection or a circuit breaker. Alternatively, a fused supply would suffice
AC Mains Connection
The power supply board has three screw terminals connector assigned for the connection of an AC supply.
Pin 1 = Earth
Pin 2 = Live input
Pin 3 = Neutral input
Recommendation for mains input cable. 3-Core – 16 AWG Conductors having cross sectional area of 0.75mm2minimum (24/0.2)
DC Voltage Connection
The power supply board has two screw terminals assigned for the connection of a DC supply
Pin 4 = +24V DC input
Pin 5 = 0V DC input
Cable Routing
Due to the low signal levels generated by gas detectors it is recommended that all wiring to the sensors by segregated away from
AC mains or other high voltage/power lines to avoid interference.
Cable Screening
The use of a screened cable is recommended for the installation of all detector heads. The screening is used to minimize the effects
of electrical interference generated by external equipment e.g. motors, switchgear etc. The correct strategy for connecting the
screens depends upon the area in which the detector head is to be used (i.e. hazardous/ non-hazardous). In all cases the screen
should not be connected at the detector head

4.2 Sensor Transmitter Installation
Mounting location for the gas detectors need to be considered individually, initial points for consideration are:
Ensure all gas detectors are mounted to allow routine calibration and maintenance to be carried out as required.
Ensure the proposed site will not interfere with movement of existing equipment, e.g. cranes, doors etc
Install all cables neatly and securely.
Detectors for gases that are lighter than air should be positioned at, or below, a high level.
Detectors for gases that are heavier than air should be located at below head height.
Avoid location the gas detectors adjacent to potential sources of radio frequency interference, e.g. radio transmitters,
control switchgear, motors etc.
Ensure the detectors are mounted with sufficient space to allow air movement around the sensor section.

5.0 Operation
When a preset alarm point is reached, visual and/or audio alarms are activated. The backlit graphics display automatically displays the
channel in alarm and an alarm level Led(s) are activated on the control panel. The LC-8 is factory set to maintain these alarms until
they are acknowledged.
5.1 LC-Series Microcontroller Module
Situated within the LC Control Unit front panel is the Microcontroller Module. This module communicates with all Input channels
connected to the system PCB.
The Microcontroller Module provides a user interface in the form of a back lit graphics display and a four-button multifunction
keypad.
Three LED indications are provided directly by the Microcontroller Module and these are visible via MCU front panel:
Green LED for power.
Red LED indication of Alarm level 1.
Red LED indication of Alarm level 2
Red LED indication of alarm level 3.
Yellow LED indication of fault condition.
An Audible signal is also provided by a sounder mounted within Microcontroller module. This provides a local audible tone during
alarm or conditions.
The Microcontroller Module also provides the user with many configuration and interrogation facilities via the LCD and keypad.
These facilities include:
Sensor Configuration.
Allows adjustment of Sensor type and range (e.g. Flammable 100%LEL).
Calibration of the system.
This allows each channel to be calibrated independently. The sensor zero point and span can both be set via this function.
Calibration of the retransmitted output for each channel.
Calibration of the channel power supply.
Input Module Relay Configuration.
Each Input Module contains two relays for alarm levels 1 and 2. The alarm levels can be individually set to be either rising
or falling.
Fault relay.
All relays can be configured normally energized or de-energized as required. Latching and non-latching functions can also
be selected.
The microcontroller module contains all of the software required to communicate with up to four detecting channels. The software
is common to all LC Series Control Units.

5.2 Analogue Output Configuration
In addition to providing the connections for various connector types, the Input Module can also provide an analogue output. This
output mimics the signal detected so that it may be used by external equipment (e.g. chart recorders, data loggers) for a variety of
purposes.
NOTE: It is important to ensure that the Analogue Output is calibrated if in use (refer to ‘MCU Software Configuration and
System Calibration Manual’).

6.0 Maintenance
Routine Servicing
The MCU Control Unit will provide a reliable and fault free service but they rely upon sensible housekeeping and regular calibrations.
It is recommended that the system be calibrated at least once every six months. This can be arranged with Status Scientific Controls

Routine Inspection
It is advisable to periodically inspect the LC Control Unit Installation:
Check cables to ensure no damage has occurred.
Clean control unit casing using a clean cloth.
Clean detector heads using a clean DAMP cloth.
NOTE: Use of a dry cloth would constitute a static hazard.
Inspect detector heads and ensure the sensor housings aperture is not obstructed.
NOTE: Do not use solvents to clean the LCD display window on the control units or the detector heads
The time interval between routine inspections will depend upon the area in which the equipment is installed. A clean laboratory
installation may only require inspection at the time of calibration, whereas an installation in a particularly dirty environment may
require weekly inspections. It is the responsibility of the system engineer to assess the installation environment and determine the
frequency of routine inspections
