It is important that you read this entire manual carefully and thoroughly.
Limitation of Liability
■ OLDHAM shall not be held responsible for any damage to the equipment or for any
physical injury or death resulting in whole or in part from the inappropriate use or
installation of the equipment, non-compliance with any and all instructions, warnings,
standards and/or regulations in force.
■ No business, person or legal entity may assume responsibility on behalf of OLDHAM,
even though they may be involved in the sale of OLDHAM products.
■ OLDHAM shall not be responsible for any direct or indirect damage, or any direct or
indirect consequence, resulting from the sale and use of any of its products UNLESS
SUCH PRODUCTS HAVE BEEN SELECTED BY OLDHAM ACCORDING TO THE
APPLICATION.
Ownership clauses
■ The drawings, specifications, and information herein contain confidential information
that is the property of OLDHAM.
■ This information shall not, either in whole or in part, by physical, electronic, or any
other means whatsoever, be reproduced, copied, divulged, translated, or used as the

Warnings
■ This is not a contractual document. OLDHAM reserves the right to alter the technical
features of its equipment at any time and for any reason without prior notice.
■ READ THESE INSTRUCTIONS CAREFULLY BEFORE USING FOR THE FIRST
TIME: these instructions should be read by all persons who have or will have
responsibility for the use, maintenance, or repair of the instrument.
■ This instrument shall only be deemed to be in conformance with the published

Important Information
The modification of the material and the use of parts of an unspecified origin
shall entail the cancellation of any form of warranty.
The use of the unit has been projected for the applications specified in the
technical characteristics. Exceeding the indicated values cannot in any case
be authorized.
Catalytic sensors are susceptible to poisoning by traces of several
substances. This leads to an inhibition which can be permanent or temporary
depending on the contaminant, the concentration of the contaminant, the
duration of exposure to the contaminant.
Poisoning may result from exposure to substances as:
• silicones (e.g. waterproofing, adhesives, release agents, special oils
and greases, certain medical products, commercial cleaning agents)
• tetraethyl lead (e.g. leaded petrol, particularly aviation petrol ‘Avgas’)
• sulfur compounds (sulfur dioxide, hydrogen sulfide)
• halogenated compounds (R134a, HFO, etc.)
• organo-phosphorus compounds (e.g. herbicides, insecticides, and
phosphate esters in fireproof hydraulic fluids)
Oldham recommends regular testing of fixed gas detection installations (read
Chapter 8).
Destruction of equipment
European Union only. This symbol indicates that, in conformity with
directive DEEE (2002/96/CE) and in accordance with local regulations,
this product must not be discarded with household waste.
It must be disposed of in a collection area that is designated for this
purpose, for example at a site that is officially designated for recycling of

Chapter 2 | Transmitter Overview
Purpose
Gas detector OLCT 80 is a digital and analog transmitter designed to measure
combustible and toxic gases, as well as oxygen levels, in ATEX zones. The
OLCT 80 has 2 auxiliary inputs, ANA1 and ANA2, with a 4-20 mA signal, to
monitor up to 3 parameters simultaneously.
The transmitter also includes a digital LCD display, two alarm relays with
programmable thresholds and a fault relay.
The device is programmed using an intrinsically-safe infrared remote control
that can be used in ATEX zones.
Versions
Explosion-proof, intrinsically-safe versions
The following types of transmitters are available:
■ Explosion-proof: the enclosure and sensor pack assembly is explosion-
proof. The explosion-proof certified version is designated OLCT 80d.
■ Explosion-proof + intrinsically-safe: the transmitter's enclosure is explosion-
proof and the sensor pack is intrinsically-safe. Only the versions using an
electrochemical sensor are available in this style. The explosion-proof,
intrinsically-safe certified version is designated OLCT 80id.
The table below lists the versions available.

Local and remote sensor versions
There are two different options for the OLCT 80:
■ OLCT 80, which uses a local sensor. It consists of an explosion-proof
transmitter with an integrated intrinsically-safe detection module (B) or
explosion-proof detection module (A).
■ OLCT 80D, which uses a remote sensor. It consists of an explosion-proof
transmitter with a remote intrinsically-safe detection module (D) or explosionproof detection module (C).

Differentiating explosion-proof and intrinsically-safe sensors
In addition to different ATEX markings, explosion-proof and intrinsically-safe
sensors can also be distinguished by the color of their sensor pack:
■ Explosion-proof sensor: unpainted stainless steel sensor equipped with a
sintered metal piece (2 and 4).
■ Intrinsically-safe sensor: blue stainless steel sensor equipped with a
protective Teflon membrane (1 and 3).

Infrared remote control
Description
The IR20 infrared remote control is a stand-alone device that can be used to
configure and control the OLCT 80 remotely without opening its housing.
Certified intrinsically safe, it can be used in IIC-type explosive atmospheres in
surface industries. The maximum range of this remote control is approximately
5 meters under normal daylight conditions. The remote control's rear battery
slot holds two AA 1.5-V batteries.
The leather case must be used in ATEX zones.

Chapter 3 | Menus
Purpose of the menus
The menus allow the user to perform various operations in relation to the OLCT
80's settings (configure the ANA1/ANA2 sensors, alarm thresholds and relays,
RS485 connection, date and time, etc.).
These menus can be accessed using the infrared remote control,
without opening the cover of the OLCT 80. It is important to take the
necessary safety precautions before opening the cover if the device
is installed in an ATEX zone. These precautions include:
■ Obtaining a hot-work permit from the relevant department.
■ Using a portable for detection of combustible gases at all times.
■ Using an intrinsically-safe multimeter, where applicable.
■ Performing the operation as quickly as possible.
This pertains to all OLCT 80 versions, whether equipped with an
explosion-proof or intrinsically-safe sensor pack.
Accessing the menus
Follow the steps below:
■ Point the infrared remote control
toward the OLCT 80.
Figure 12: the remote control pointed
toward the OLCT 80.
■ Push the Menu button on the
remote control.
■ The AFF MES menu will appear
on the display of the OLCT 80.
