§
§ The OLCT80 is an analogue/digital transmitter designed for gas detection. It can be installed and addressed in
a network or connected to any acquisition system managing an analogue signal (0 to 20 mA).
§
§ The OLCT80 comprises a transmitter (electronic section) and an integrated or remote sensor on the version
OLCT80D.
§
§ It has integrated alarms allowing it to be used as a stand-alone measurement unit, even in ATEX-classified
potentially explosive zones (see Chapter VII).
§
§ In a zone classified as potentially explosive, the OLCT80 can be used as a stand-alone measurement unit.
§
§ An intrinsically safe remote control unit is used for non-intrusive dialogue with the transmitter during
maintenance or configuration operations.
§
§ The OLCT80 can be used as a digital repeater on the network (up to a maximum of 3) when it is installation in
loop configuration. The maximum length of the loop in this case is 4.8 km.
§
§ It has two auxiliary analogue inputs allowing the connection of two additional detectors of any type (gas,
flame, temperature, pressure, etc.), provided that they deliver a 4-20 mA analogue signal (Fig. 5).
§
§ It feeds two alarm contacts and a technical fault contact (2A/250VAC, potential-free).
•
• The relays are actuated:
−
− By the OLCT80 itself using the programmed alarm thresholds,
−
− And/or by the MX62 central unit if the OLCT80 is connected to it.

§Observe the precautions described above.
§Check the overall dimensions of the detector in situ: see Fig. 2 or 3
§Secure the detector: see figures below:
-FIG. 2 : Version with integrated detector;
-FIG. 3 : Version with remote infrared detector
-FIG. 4 : Version with remote detector.
Note: For the OLCT80 with integrated detector, the nose piece must always point downwards.

Carry out installation in compliance with the prevailing standards and classification of the zone.
To ensure that the detector operates correctly, the cable resistance must remain within the limits specified in the
technical characteristics table for the measurement unit connected and the OLCT80 transmitter.

Referring to Figure 1 or 1b as the case may be (stand-alone or connected to anISC/OLDHAM central unit):
§Remove the protection cover and the display card to gain access to the connection terminals
§Check that the main circuit is correctly programmed for the type of detector connected (see Figure 7)
§Feed the cables into the cable glands
§Connect the 2 active wires of the power supply (connectors J1 and J2): V+ and V-
§Connect the transmitter to the earth via the external or internal earth terminals
§Connect the wires for the functions used (4-20 mA, RS485, relays, etc.)
§Refit the display circuit and protection cover correctly
§Check that all cable glands and plugs are tight.

§Check that connection and fastening have been carried out correctly,
§Disable the alarms of the facility to prevent any unintentional triggering during the operation,
§Switch on the powersupply and leave to stabilise for 2 to 3 minutes,
§During the first minute of warming up, the detector delivers a current of 2 mA,
§Check the zero (4 mA) and response to the standard reference gas,
§If necessary, adjust the zero and sensitivity,
§Set the system to normal operation by deactivating the disable.
Note: The detector will now run an automatic cyclic self-test.

Caution:The actions described in this paragraph may affect the reliability of detection and must only be carried
out by authorised and trained personnel.

Gas detection instruments are potential life-saving devices. Recognizing this fact, Industrial Scientific Corporation
recommends that a functional “bump” test be performed on every fixed gas-monitoring instruments as part of a regular
maintenance program. A functional test is defined as a brief exposure of the detector to a concentration of gas(es) in
excess of the lowest alarm set-point for each sensor for the purpose of verifying sensor and alarm operation and is not
intended to be a measure of the accuracy of the instrument.
Industrial scientific further recommends that a full instrument calibration be performed using a certified
concentration(s) of calibration gas(es) quarterly, every 3 months.* Calibrations may be necessary more or less
frequently based, for example, on application, field conditions, exposure to gas, sensor technology, and environmental
conditions. The frequency of calibration is best determined by company policy or local regulatory agencies.
If an instrument fails to operate properly during any functional “bump” test, a full instrument calibration should be
performed successfully prior to use.
These recommendations are based on safe work procedures, industry best practises, and regulatory standards to ensure
worker safety. Industrial scientific is not responsible for setting safety practices and policies.
* For new installations it may be prudent to carry out bump tests frequently at first (perhaps weekly), increasing the
time intervals (to, perhaps, monthly or more) as confidence grows with experience in the installation concerned, on the
basis of the maintenance record.
1.1. Calibration
Calibration is necessary in the following cases:
-Start-up
-Replacement of the sensor block of any electronic circuit
-Constant zero drift
-Periodic test.
Items required for calibration:
-Gas calibration kit (bottle of standard reference gas and its accessories)
-IR20 remote control: non-intrusive setting (access to the maintenance menu)
-Knowledge of the procedure.
Calibration procedure
Preparation
-Check that the facility is operating correctly
-Set up the gas intake system (6331137 or 6331141) depending on the gas (see Page 23)
-Connect the kit pipe to the calibration pipe
-Inject air or standard reference gas from the bottles at a rate of 1 l/mn for explosive gases and 0.5 l/mn for other
gases.
-The concentration of standard reference gas must usually be at least 50% of the measurement range.
-Use the IR20 remote control to carry out the actions.
Calibration
-Check that only clean air is present in the detector, otherwise purge with cylinder of clean air to set up zero.
-Using the remote control unit:
-Validate (1) the Calibration menu (see Section III.1)
-If necessary change the value of the standard reference gas ("+", "-", "Enter" keys on the remote control unit)
-Initialise (1) the Zero function
-Wait for the measurement to stabilise
-Validate (1)
-Initialise (1) the Sensitivity function
-Inject the standard reference gas and wait for the measurement to stabilise
-Validate (1) and confirm (1)
-Finally, stop gas injection and remove the kit from the detector

§When its performance deteriorates or calibration is impossible,
§During preventive maintenance
How?
§Switch off the measurement channel concerned
§Remove the sensor block to be replaced
§Replace it with a new, pre-calibrated block
§Start up the channel, run the sensor replacement menu and check that it operates correctly
§If necessary repeat zero setting (pure air) and sensitivity setting (standard reference gas) using the
Calibration menu (IV.1.1).

Concerning the conservation, of the protection and the improvement of the quality of the environment,
as well as for the protection of the health of the persons and the careful and rational use of natural
resources, OLCT80 has to be the object of a selective collection for the electronic equipments and
cannot be scrapped with the normal domestic waste. The user thus has the obligation to separate the
OLCT80 of the other waste so as to guarantee that it is recycled in a sure way at the environmental
level. For more details of the existing sites of collection, contact the local administration or the
distributor of this product.
