3.0 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.
3.1 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 0.75mm
(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 minimise 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

3.2 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.

4.0 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 acknowledge
4.1 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:
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.
Input Module Relay Configuration.
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.
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.
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.
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.

LC SERIES ENMET
5.0 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 as part of a maintenance contract.
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

Returning an Instrument for Repair
ENMET instruments may be returned to the factory or any one of our Field Service Centers for regular repair

service work.
When returning an instrument to the factory or service center for service, paperwork must be included which
contains the following information:
A purchase order number or reference number.
A contact name with return address, telephone and fax numbers
Specific instructions regarding desired service or description
of the problems being encountered.

for warranty consideration.

sure to include a fax number.
Providing the above information assists in the expedient repair and return of your unit.
Failure to provide this information can result in processing delays.
ENMET charges a one hour minimum billing for all approved repairs with additional time billed to the closest
tenth of an hour. All instruments sent to ENMET are subject to a minimum evaluation fee, even if returned
unrepaired. Unclaimed instruments that ENMET has received without appropriate paperwork or attempts to
advise repair costs that have been unanswered, after a period of 60 days, may be disposed of or returned
unrepaired COD with the evaluation fee.
Service centers may have different rates or terms. Be sure to contact them for this information.
Repaired instruments are returned by UPS/FedEx Ground and are not insured unless otherwise
specified. If expedited shipping methods or insurance is required, it must be stated in your paperwork.

If a component is purchased and installed in the field, and fails within the warranty term, it can be
returned to ENMET and will be replaced, free of charge, per ENMET’s returned goods procedure.
If the entire instrument is returned to ENMET with the defective item installed, the item will be replaced
at no cost, but the instrument will be subject to labor charges at half of the standard rate.
