ATTENTION!
Before starting to operate IT-12-Exd explosion-proof test transmitter, carefully
read the Operating Manual.
1. DESCRIPTION
The purpose of IT-12-Exd explosion-proof test transmitter (hereinafter “the
transmitter”) is remote setting of main parameters of Spectron-601-Exd series flame
detectors issued on 01.01.2017 or later.
•activating / deactivating the function of automatic transition from the Fire mode
to the Stand-by mode;
•switching detector’s Long Distance and Short Distance sensitivity modes;
•changing detector’s minimal response time.
The transmitter is produced in compliance with requirements to ex-proof equipment
of subgroups IIA, IIB, IIC according to TR CU 012/2011, GOST 30852.0 (IEC
60079-0), GOST 30852.1 (IEC 60079-1) and complies with 1ExdIICT6 explosion-
proof marking.
The transmitter is designed to be used in indoors and outdoors explosion-hazard
areas according to the classification in chapter 7.3. of Electrical Installation Code
(sixth edition), GOST 30852.9, GOST 30852.13 and other directives that outline
application of equipment in explosion-hazard areas.

3. USAGE INFORMATION
3.1. DESIGN AND FUNCTION
The transmitter includes an aluminum body that consists of a reflector, an
electronic board with light-emitting diodes, a mode selection switch and a battery
compartment cover –see Fig. 2. The battery compartment is filled with compound.
The transmitter has 2 functional states:
Functional state 1:
•setting the parameter of Ignition Source Control - activating / deactivating the
function of automatic transition from the Fire mode to the Stand-by mode;
•setting the Sensitivity parameter - switching detector’s Long Distance and Short
Distance sensitivity modes. Functional state 2:
•setting Response Time parameter - selecting the minimal time of detector’s
actuation: 3, 10, 15 or 22 sec.
ATTENTION!
Functional state 1- green light-emitting diodes are on.
Functional state 2- red light-emitting diodes are on.

3.2. CHANGING DETECTOR PARAMETERS
Detector parameters are changed at the distance of maximum 25 meters. Before you
begin make sure that the detector is in the Stand-by mode - single or double indicator
flashes with a 7-second interval.
Select the required mode of transmitter’s operation (F1, F2, F3 or F4) from Table 2
to change the desired parameter.
Turn the transmitter on by turning the switch to align the marking on the body with
the selected mode - F1, F2, F3 or F4. Green light-emitting diodes will turn on at this
time (functional state 1); they start blinking with single or multiple flashes depending
on the selected mode.
The transmitter can be switched to functional state 2 by turning one of the selected
modes (F1, F2, F3 or F4) off for a short time (the switch is in the “off” position
between “F” modes) and then selecting the same mode again.
Example: F1 mode is on, green light-emitting diodes are blinking - transmitter is in
state 1. Put the switch in the “off” state and then turn F1 mode on again - the
transmitter will switch to state 2 and red light-emitting diodes will activate.
For 6 - 8 seconds after turning on, the transmitter reflects only light indicators so
that the nature of flashes could confirm the correct mode selection.
After 6 - 8 seconds the transmitter’s light-emitting diodes will start blinking twice
as frequently, which means a parameter change command started transmitting to the
detector. Point the transmitter in the direction of the detector’s front-face surface and
try to align the transmitter’s axis with the direction to the detector as much as
possible. For the first 5 - 6 seconds the detector’s indicator will show the previous
state of the parameter and will then switch to the new state. The behavior of the
detector’s indicator is demonstrated in Table 2.
After receiving the confirmation of changing the detector’s parameter, turn the
transmitter off by turning the switch until it clicks (light-emitting diodes must go off).

After you turn the transmitter off, the detector will automatically go into the Stand-
by mode.

3.3. BATTERY CHARGING
ATTENTION!
Only charge batteries outside of explosion-hazard areas.
To charge batteries:
•Make sure the transmitter is off (the marking on the body is not aligned with
F1, F2, F3 or F4 signage on the switch, the light-emitting diodes are off);
•Make sure the battery’s temperature is from 0°С to +45°С;
•Unscrew the battery compartment cover, see Fig.2;
•Connect the charging adaptor (included in the delivery package) to 220V, 50Hz
network and to the transmitter’s slot. The batteries need at least 2.5 hours to
charge.
•Disconnect the charging adaptor and screw the battery compartment cover shut
with a 19mm wrench until the sealing ring is compressed;
•The thread joint of the battery compartment cover is covered with TSIATIM-
221 GOST 9433 lubricant.
NOTE
Charge the batteries before using the transmitter. During long storage, battery
capacity is reduced due to standing loss.
3.4. SAFE OPERATION REQUIREMENTS
Assembly and operation shall be performed in compliance with Operating Manual
requirements, chapter 7.3 of “Electric Installation Code”, GOST 30852.0, GOST
30852.1.

Observance of safety rules is a necessary requirement for safe operation and
functioning of the transmitter.
Operation of the transmitter should be performed by authorized personnel that
received training, an assessment by a certification committee and got acquainted with
the Operating Manual and instructed on safe service and maintenance.
Any work associated with removing the battery compartment cover must be
performed only outside of explosion-hazard areas.
Maintenance personnel shall be responsible for occupational safety.
Explosion safety of the transmitter is provided by:
•type “d” ex-proof shell;
•in compliance with GOST 30852.1 conducting parts and sparking parts are
installed inside an ex-proof body that is resistant to explosion pressure and,
along with protection means, prevents explosion transfer to the explosion-
hazard environment; the battery compartment cover is threaded to the body.
•in normal operating mode, the heating temperature of the outer surface does not
exceed temperatures recommended for electrical equipment of the
corresponding temperature class, in compliance with GOST 30852.0;
•the shell corresponds to the high degree of mechanic stress in compliance with
GOST 30852.0.
4. TROUBLESHOOTING
