II. IMPLEMENTATION During its first start-up, and also after remaining inactive for more than a month, the detector must be charged, discharged and totally recharged before use. In addition, you are reminded that a gas test must be carried out on any portable gas detector before going to the site.
1. POWER SUPPLY This is supplied by: 3 LR6 1.5 V type AA alkaline dry cells* (DURACEL MN 1500). Or 1 NimH rechargeable batteries pack*
EX 2000 « industrial » EX 2000 « mining » CK 2000
3 separated elements dry cells or
NimH batteries pack
Pack batteries NimH
Pack batteries NimH
The “power supply units” cannot be exchanged in a dangerous area. Warning : substitution of components may impair intrinsic safety. Under the normal conditions of use the instrument will run for
30 hours with dry cells. 24 hours with NimH batteries
IMPORTANT: The instrument is certified for use in group5 I and II explosive atmospheres and only when it is equipped with cells or batteries of a type recommended by the maker. CSA certication covers the following batteries : Duracell MN1500, Panasonic P80 AAS, Saft VSE AA 850, Panasonic HHR 1500, Varta VH 1200 AA) .Recharging the batteries: When it is equipped with accumulators, the device can be recharged by inserting it into a type CR 2002 two-position intelligent charger, or by connecting a “simple” charger to the side socket of the instrument (Industrial EX2000) Depending on circumstances, this charge may last from 4 to 24 hours maximum. IMPORTANT: In order to maximize the life of the batteries, the OLDHAM company recommends that the batteries be fully discharged6 and recharged to the maximum at least once a month on average. * Note : the choice to use dry cells or rechargeable batteries is made by a switch (fig 2, rep 5, page 13)
5 EX2000 "MINING" version : only GROUP I / EX2000 "INDUSTRIAL" versions : only GROUP II 6 for example, by using the Industrial EX 2000 until it goes dead automatically.

2. MEASUREMENT MODULE (FIG. 2. Rep 1)
2.1. Presentation Being a vital element of the gas detector, the measurement module must be treated with care. Mechanical impacts, splashing with water etc. may impair the quality of the measurement or even, in extreme cases, destroy the modules. A water-repellent and anti-dust filter (fig. 2. rep 3) fixed to the “sintered” metal protects the “head” of the module. Different types of modules will be used depending on the version of the instrument.
EX 2000 « industrial »
EX 2000 « mining »
CK 2000
Module type Catalytic Catalytic Catharometric
Measurement range 0 to 100 % LEL 0 to 5, 00 % CH4 or 0 to 4,4% CH4
0 to 100 % v/v gas in air
Warning : substitution of components may impair intrinsic safety.
2.2. Fitting or replacement The module can be plugged in and is accessible once the anti-rotation device has been removed and its protective cap unscrewed (fig. 2. rep 2). It is located on the top of the instrument.
2.3. Precautions The modules are sensitive to certain poisons which can cause desensitivation of them : emanations of silicones at concentrations > 10 ppm, chlorinated or sulphurated products at concentrations > 100 ppm. A lack of oxygen (< 15% O2) may cause a too low signal compared to normal conditions and then would indicate an under-estimated measurement which would be dangerous for the user. The use in an O2 enriched atmosphere may impair the electrical safety.

3. REMOTE SAMPLING
3.1. Presentation:
The gas concentrations can be measured or checked, before entering a vault or highly inaccessible locations using a remote sampling probe.
3.2. The various systems:
The remote sampling systems can consist of a telescopic, rigid or semi-rigid stem and a manual suction bulb.
3.3. Use:
The sampling system
Assemble the sampling system used (probe/bulb/tube/water-repellent filter) and then connect the hose to the gas inlet pipe.
rep. 1
13
Fitting the sampling system to the EX 2000 « Industrial » and « Catharometer » :
The gas inlet pipe (rep. 1) can be inserted into the module very easily, quickly and without tooling.
Fitting the sampling to the EX2000 « Mining » :
The EX2000 « Mining » is equipped with a threaded nozzle.
The gas introduction pipe screws itself directly into the module, without tooling, without any dismantling or adaptation of anything.
Use: pumping and measurement
Using the manual pumping bulb, pump at least 8 times in under 20 seconds in order to obtain a reliable reading. Wait for the measurements to stabilize before confirming them.
Dismantling the pumping system
Never forget to withdraw the gas inlet pipe after using a sampling system or after calibration. This would give rise to underestimation of the measurements which could be fatal to the user!
4. CARRIAGE OF THE INSTRUMENTS, THE OPTIONS:
-The metal clip (fig. 2. Rep4) The user can get on with his work while leaving the instrument to monitor the surrounding atmosphere, attached to his clothing using the clip provided for the purpose. Attention: in order to be able to take readings correctly, the module should never be obstructed. - The leather bag with shoulder strap: provides protection for the EX 2000 while leaving the user’s hands free. Although alerted of correct operation by a loud audible signal, it is essential for the user to be able to monitor the alarm indicator easily.

IV. MAINTENANCE and SERVICING
Important: For any help, please refer to the standard CENELEC EN 50 073 « Guide for selection, installation, use and maintenance of apparatus for the detection and measurement of combustible gases or oxygen ».
Being a safety instrument, it is necessary to calibrate it at least twice a year.
This work is reserved for authorized and qualified personnel since it could possibly jeopardize the safety of detection
All these instructions are also submitted to the domestic regulations of each country.
1. MAINTENANCE OF THE EX2000 AND CK2000
The alarm threshold 1 (programming), can be easily altered and preventive calibration or calibration following the replacement of the module can be carried out using a maintenance programme built into the instrument. In order to use this programme, the maintenance plug supplied with the accessories must be fitted into the socket located on the left side of the instrument (fig. 1. rep 6).
Then press simultaneously on the following keys
A pictogram appears at the bottom right of the display: a key, at the same time than the "programming" menu.
You can now reach the "programming" and "calibration" menus pressing the key
23
1.1. Programming

1.2. Calibration
The only means of checking that the instrument’s detection function is working properly is the calibration performed with the help of a standard gas. This “recommended” standard gas is specified on the label of the detector. Nevertheless, some other standard gas may be used on referring to the table of coefficients: Chapter VIII of this manual. Hence, calibration must be carried out :
- Every 6 months minimum - After an exposure at high gas concentrations - After more than one month storage with no use - After a module change - Following an instrument fault Within the calibration menu the “visible and audible” alarms are not triggered. The “calibration” menu makes it possible to check and adjust the zero in pure air and the sensitivity to gas. CAUTION :
CSA recommends as follows :
Before each day’s usage sensitivity must be tested on a known concentration of CH4 equivalent to 25-50% of full scale concentration. Accuracy may be corrected (see adjustment procedure). High off-scale readings may indicate an explosive concentration.

8 Precaution during the calibration : Check that the flow rate is of 60 l/h. For all versions, use a content with a concentration >10% LEL of the range, otherwise only the zero will be confirmed, maintaining a flow rate of 60 l/h. For CK2000 : contents highly above the UEL (Upper Explosivity Limit) of the gas are recommended (50% for example). Alternatively, a calibration with a mixture in nitrogen can be used, but a mixture in air is nonetheless preferred, as nitrogen and air have slightly different conductivity.
