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.

ARNING: The compliance o f the installation to appropriate codes is not ENMET’s responsibility.

W

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 = Ear th
Pin 2 = Live i nput
Pin 3 = Neutral input
Recommendation for mains input cable. 3-Core – 16 AWG Conductors having cross sectional area of 0.75mm

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 D C 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, doo r s e tc
 Install all cables neatly and securely.
 Detectors for gases that are lighter than air should be positioned a t, 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 Microcontr oll er Module

Situated within the LC Control Unit front panel is the Microcontroller Module. This module communica te s 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 configuratio n 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 retransmitte d 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. Lat ching and non-latching functions ca n 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.

5.2.3 1-5V Voltage Output

The LC Control Unit can provide a volta ge o utp ut.
i.e. zero gas = 1V
full scale = 5V

This output is not ideal when transmitting a signal over a large distance. The resistance of a cable attached will cause a voltage
drop to occur.

Switch ON J11, J12 and J14.

NOTE: Incorrect jumper switch configuration can cause damage to the system.

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 Scient ific Contr ols
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 inspectio n at the time of calibration, whereas an installation in a particularly dirty environment may
require weekly inspections. It is the re sponsibility of the syste m engineer to assess the installation environment and determine the
frequency o f routine i ns pections
