IMPORTANT INSTRUCTIONS:
• This manual contains instructions for the MCS-12-IS (in the rest of the manual called by calibrator)
designed for use in hazardous areas. Read the entire manual before using the calibrator.
• Before using the calibrator, carefully read the section “Special conditions for safe use”.
• Keep the calibrator in a dry environment whenever possible.
• In case of failure or suspected failure, especially in safe operation, send the instrument for repair to the
factory., always send the instrument to the factory for repair.
• When not in daily use, before starting up, let the calibrator be turned on for at least one hour.
The warranty conditions are available on our website:

Special conditions for safe use
• Use the calibrator only as described in this technical manual.
• The battery should only be charged in a safe area, using the charger provided. To avoid explosion or fire, use only
the battery (BT12-IS) and charger (CG12-IS) specified by Presys.
• Never replace the battery in a hazardous area.
• Do not use the serial communication port in an explosive atmosphere.
• The calibrator's aluminum metallic enclosure is protected by a leather case (BC12-IS) that should always house it
when in a hazardous area.
• The intrinsic safety of the instrument is only valid for the connections shown in this manual, respecting the
intrinsically safe input and output parameters. The entity parameters and connections are illustrated in items 2.4, 2.5
and 2.6 - Operation.
• To avoid damage to the instrument and invalidate the Ex certification, never apply a voltage greater than 30 V
between the terminals and the metallic enclosure of the instrument.
• Never open the calibrator. Opening the enclosure may void the calibrator Ex certification.
• Do not use tools on the calibrator that may cause sparks; this practice can cause an explosion.
• Never perform maintenance on the calibrator; the components used are specified and cannot be changed.
• Never use the calibrator in an area close to explosive dust.

1 - Introduction
1.1. General Description
MCS-12-IS is a universal process calibrator designed to be used in hazardous areas where explosive or
flammable vapors are present. Enables the measurement and generation of signals used in Instrumentation and
Process Control. It is designed to provide the necessary resources in order to facilitate the work of keeping the
instruments of the process adjusted and calibrated. It has high levels of accuracy, including aspects related to
changes in ambient temperature and the maintenance of specifications over long periods of time. Its construction
takes into account the field use, thus including items of great value such as: bag with straps to fasten on the belt or
on the shoulder allowing freedom for the hands, liquid crystal display with high contrast facilitating visibility in low light
environments, rechargeable battery and large memory capacity to store the values obtained, making it possible to
transfer them to the microcomputer, when necessary. In addition to these, several construction factors that add
quality and efficiency to MCS-12-IS can be mentioned.
It incorporates the most modern concepts of union of adjustments and calibrations with information
technology, where data are shared both by the instrument and by the computer, giving efficiency to the treatment of
information, in the form of issuing reports and certificates, the automated management of tasks and the organization
and archiving of data, that is, it covers an entire context aimed at complying with quality procedures, mainly related to
the ISO-9000 standard.

Probe
Independent input for RTD (Probe). Probe is a high accuracy 4-wire Pt100 available under previous consult.
For a higher level of accuracy, it is possible to configure the parameters of the sensor Callendar-Van Dusen
curve in the MCS-12-IS, correcting the errors found in the sensor certificate (see section 3.8.3 - Probe).
Software Special Functions
- Any output programmable in:
1) STEP: 10%, 20%, 25% or up to 11 programmable setpoints via key or adjustable time.
2) RAMP: up and down with programmable travel and dwell time.
- Special functions:
1) SCALE: makes the scaling of both input and output in 6 digits and allows the configuration of decimal point.
2) CAL: scales the input in same unit of output.
3) CONV: converts any input into any output, galvanically isolated.
- MEM command: It can store up to eight types of configuration chosen by user.

2.2. Battery and charger
The calibrator is supplied with rechargeable batteries which enable up to 8 hours of continuous use. This
autonomy is reduced when the current output or the 12 Vdc power supply for transmitters. A charger is also provided,
which can be connected to 110 or 220 Vac. Care should be taken when changing the 110-220 Vac selection switch in
the charger; time required for a full charge is 14 hours. When the display indicates LOW BAT, it is necessary to
recharge the instrument, which will continue in operation for a few minutes. The battery should only be charged in
a safe area. Only the charger (CG12-IS) and battery (BT12-IS) specified by Presys must be used, otherwise
there is a risk of fire or explosion.
The batteries used by the calibrator are made of Nickel - Metal Hydride (Ni - MH). This new technology
for rechargeable batteries does not have the undesirable characteristics of memory effect and environmental
pollution as their preceding batteries made of Nickel Cadmium (Ni-Cd).
2.3. Using Calibrator: Basic Functions
When powered on, the calibrator goes through a self-test routine and shows the last adjustment date and
the value of the battery voltage. In case of failure, it displays a message to indicate RAM error or E2PROM error; if
that occurs, the instrument should be sent for repair. The battery voltage is constantly monitored and the low battery
warning is provided.

After the self-test is completed, the display shows the starting menu:
 IN OUT EXEC
CONF ADJ COM
IN / OUT - Selects the input/output functions
ADJ - Selects functions which adjust the calibrator itself (see chapter Adjustment).
Do not enter in ADJ option before reading the warning in section 4 - Adjustment.
COM - Refers to the communication with the computer, described in an appropriate manual.
EXEC - Used to activate an input or output option which has been previously selected.
CONF - Takes to the sub-menu:
 CF PRG MEM DATE
FN BAT LCD P
CF changes both the input and output temperature units from °C to °F and vice-versa. It also enables to
choose the temperature scale between IPTS-68 and ITS-90. It follows the encoding scheme described below:
C-90 ITS-90 temperature scale in Celsius degrees.
F-68 IPTS-68 temperature scale in Fahrenheit degrees.
