1. Important Remarks
IMPORTANT
▷This document is not a contractually binding document, WISE CONTROL reserves the right to make any changes, without
notice, to the technical characteristics of its equipment in order to improve performance levels, in the interest of its customers.
▷Carefully read the instructions before all first use: This instruction manual must be read by any person who is, or will be,
responsible for the use, maintenance or repair of this equipment.
▷This equipment will conform with the specified performance levels only if it is used, maintained and repaired in accordance
with the directives of WISE CONTROLand by WISE CONTROL personnel or personnel authorized by WISE CONTROL
LIMIT OF RESPONSIBILITY
▷WISE CONTROL hereby reject any and all responsibility with regard to any person for material damage, bodily injury or death
resulting in whole or in part from the inappropriate use, installation or storage of its equipment not conforming to the
instructions and to warnings and /or not conforming to standards and regulations in force.
▷WISE CONTROL does not allow or authorize any company, person or legal entity to assume such responsibility on the part of
WISE CONTROL, even if involved in the sale of the product of WISE CONTROL.
▷WISE CONTROL shall not be liable for any direct or indirect damage, or any direct or indirect legally awarded damages
resulting from the sale and use of any of its products, unless those products were specified and chosen by WISE CONTROL
for the use made of them.
WARNING
▷Do not open the transmitter enclosure with power applied unless it is verified that no combustible gases or vapors are present.
A portable gas detection instrument should be used to ensure that the area is clear of any combustible gases. Calibration or
maintenance should not be performed if there is any indication of the presence of combustible gas at the sensor.
▷It is possible for the transmitter output to drop to a low LEL level after going into high alarm and still have a dangerous level of
combustible gas present. Therefore, precautions should be taken to ensure that the combustible gas has been cleared before
considering the area safe.
▷The sintered metal flame arrestor is an integral part of the combustible gas sensor. DO NOT operate the gas detector if the
flame arrestor is damaged or missing, since the exposed element is a potential ignition source.
CAUTION
▷The wiring instructions in this manual will provide safe and proper functioning of the device under normal conditions. However,
local variations in wiring codes and regulations exist, and total compliance with these ordinances cannot be guaranteed. Be
certain that all wiring complies with all local ordinances. If in doubt, consult the local authority having jurisdiction before wiring
the system.
▷The sensor threads should be coated with silicon free grease to ease both the initial installation and future replacement of the
sensor. The junction box cover threads should also be lubricated. The use of other lubricants is not recommended, since
some materials can cause irreversible damage to the sensing element. Silicon based lubricants must never be used.

2. Introduction
GTX-1010 series is a digital combustible or toxic gas leak transmitter with microprocessor application
circuit. So you can match this detector with one indicator. It consists of the sensor, terminal and explosion
proof housing, which is designed for hydrogen circumstance.
It is upgraded product compare with before product. (easy calibration, stable) The existing transmitter has
a wiring problem because it has “I” type conduit port. But new transmitter has “T” type conduit port.
It is furnished with an explosive-proof housing with removable cover. Generally you may install the gas
detector in the area has a risk of explosion and fire by gas leakage, and you may install the indicator in
the safe area and easy monitoring area.
The GTX-1010D version allows the cell to be used in remote mode up to 15 meters (standard), allowing
detection in extreme inaccessible location or in Zone 0 in the case of the intrinsically safe (IS) version.
Smart Sensors are made of 316L stainless steel, robust and resistance to corrosive agents. Pre-
calibrated sensors can be disconnected by turning the head of the unit. The sensors, which are equipped
with a printed circuit, can be calibrated outside hazardous areas on a bench. The Microprocessor in the
PCB provides a linear 4 to 20 mAsignal, which corresponds to measuring range of gas.
Calibration and sensor sensitivity check can be performed by one person using a standard digital
voltmeter.

2) The place where dusts or corrosion gases are remained
3) The place where the ambient temperature is above 60℃or below -20℃
4) The place where dust or poisoning gas (VCM, Cl2 ) are existed
5) The place where the mechanical vibration or the shock are existed
6) The place near the high current circuit or where high induction interference is existed, an instrument
and a sensor circuit may keep away above 30 cm from the high current or the high voltage circuit,
because it makes induction interference and it would be an indication error and unstableness of
indication.

7. Operation
7.1 Operation mode
7.1.1 Sensor stabilization time (Warm-up)
You have to wait for sensor stabilization time because this unit does not act immediately.
A sensor needs stabilization time for 30 sec.
The transmission output is 3 mA for sensor stabilization time.
7.1.2 Normal action
1) Sensor stabilization time is end, then instrument act for operation mode.
Transmission output is 4 ~ 20 mAin operation mode.
2) Transmission output is changed from 4 to 20 mAdepend on the gas measuring range.
3) The signal through a line is transmitted to indicator than you adjust contact signal to fit a local condition.
7.1.3 Sensor trouble alarm
When the gas sensor is damaged or lead wire is snapped,
1) Transmission output is 2 mA(1 mA for GX-1010 or GX-1010D)
2) If transmission output is decreased below 2 mA by sensitivity decreasing, than the transmission output
is fixed to 2 mA.
7.1.4 Sensor power insufficiency alarm
If the supplied power for sensor is decreased below 18 VDC, than Transmission output is 0 mA.

7.2 Calibration for GT-1010
7.2.1 Power confirmation
1) Power check between +24V and GND terminal (+DC24V)
2) Regular power is DC18V ~ 30V.
7.2.2 Sensor heating current setting
1) Set the DC multimeter to voltage
2) Connect multimeter (+) rod to CP1 check pin,
and connect multimeter (-) rod to CP2 check pin
3) Set the check value is fitted to 295 mV
by controlling “HEAT” variable.
7.2.3 ZERO setting
1) Set the DC multimeter to voltage
2) Connect multimeter (+) rod to CP4 check pin, and connect
multimeter (-) rod to CP5 check pin If 4~20mA is not connect
to output terminal, than you may short terminal #2 and #3
3) At the clean air environment, set the check value is fitted
to 40 mV by controlling “ZERO” variable.
7.2.4 SPAN setting
1) After zero setting at the clean air environment,
inject the standard gas to sensor by using of adapter.
2) After gas injection, set the check value is corresponded
to gas concentration by controlling “SPAN” variable.
Example 1) When you inject 25% LEL gas than set the value to 80 mV.
Example 2) When you inject 50% LEL gas than set the value to 120 mV

16

7.2.3 ZERO setting
1) Set the DC multimeter to voltage
2) Connect multimeter (+) rod to CP4 check pin, and connect
multimeter (-) rod to CP5 check pin
3) At the clean air environment, set the check value is fitted
to 40 mV by controlling “ZERO” variable.

8. Others
8.1 Surge protect
When you use the spare operation device (blocking valve, relay, magnetic S/W and solenoid valve, etc.)
to an alarm output, an instrument is possible to stop operation by strong surge from output contact.At this
time, you may put the R-C damper or the barrister (TNR, ZNR) onto output contact due to protect surge
generation, and you may confirm ground state again.
8.2 Toxic protect
The property of catalyst of catalytic gas sensor is deteriorated by silicon, H2S, Cl2 and HMDS
(Hexamethyl disiloxane) gas, and the lifetime of sensor is decreased. If you have to measure a gas
leakage in this environment, then you may use the toxic protected sensor.
8.3 Repair and Examination
8.3.1 Examination with the naked eye ( more than 1 time per month )
- Harmful materials inflow check on sintered metal
- Sintered metal corrosion check
- Case corrosion check
8.3.2 Simple gas check ( more than 1 time per month )
- Alarm state confirm by 2~3 times gas injection of alarm setting point to detector
8.3.3 Standard gas calibration ( more than 1 time per 3 ~ 6 month )
- Alarm state and indication confirm by standard gas injection to detector
