3. Specication

GTD-5100F gas detector has been developed to detect gas leaked from industrial sites and various gases generated from

factories, gas storages, and manufacturing processes that produce or use toxic gases by suction method and to prevent

accidents in advance. GTD-5100F gas detector is installed in areas with gas leak hazards, continuously monitors gas leak at

all times, and measures gas by sucking in the external air using a built-in pump. It displays measurements on 7-segment LED

and supports various industrial interfaces including Analog 4-20 mA standard output, RS-485 and PoE. It provides relay contact

signal in an event of gas leak alarm. Also, DC 4-20 mA standard output is possible for connection up to max. 2500m of output

signal transmission distance between the gas detector and receiver (When CVVS or CVVSB 1.5s sq↑ shield cable is used). RS-

485 network signal can be transmitted up to 1000m (When a cable designated for RS-485 is used).

This product can be installed in areas with gas leak hazards of all toxic and flammable gases. It is a gas detector with

explosion-proof suction construction and built-in diaphragm pump and flow sensor. Gas measurement at installed site is

displayed by built-in 4-digit FND. Internal construction consists of display part that shows measurements, main control

part that measures and controls gas concentration and flow rate, and terminal part that output current output (DC 4-20

mA), RS-485 network signal or Alarm signal.

Instruction Manual 6. Operation 6. Operation

6.1. Power On

■ After checking wiring and power voltage, turn on the power switch located at the front part.

■ Power LED (Green) light on and "SELF" message, indicating that version information, equipped sensor

type (CT-S: Cartridge type Sensor), and sensor data are being loaded, is displayed. After displaying

"R180~R001", it enters measuring mode.

■

It takes approx. 180 sec (1800 sec for O2 detector). When RST (reset key) is pressed when "R180~R001" is flashing,

"R04~R01" is displayed and it returns to measuring mode.

- - When the power switch turns ON, PWR LED lights on and "UX.XX" Firmware Version information is

displayed for 1 sec on FND (concentration display part).

- When the version is displayed as XX.XX, it is in debug mode and a full version of firmware must be

downloaded.

- Sensor type that is equipped in the model is displayed.

- CT-S: Cartridge type Sensor

- During the initial exchange of information between sensor and main unit, "R180~R001" message is

displayed for 180 sec. When RST KEY is pressed at this time, it immediately enters measuring mode.

- For O2 detector, "1800~0001" is displayed and it immediately enters measuring mode when gas value

is 20.9 +/- 3%.

- Upon completion of sensor warm-up, it counts from R4~R1 then enters measuring mode.

- Count display is always displayed when it enters measuring mode from another mode.

6.2. Measuring Mode

- It displays gas concentration received from sensor on FND digital display in numbers and the current

flow rate in bar graph.

- When there is an error in sensor, messages from "E-10" to "E-33", etc. flashes and trouble LED (Orange)

lights on. (8. (Refer to Section Error & Warning Message (Troubleshooting))

- When input gas concentration from sensor is 10% higher than the set high scale value, "OUER" displays

by flashing in 0.5 sec interval.

- When gas concentration is detected to be above the alarm threshold and the alarm dwell time has

passed, alarm function runs.

- Alarm LED Lamp operation flashes in 0.5 sec interval while counting the alarm dwell time and lights on

when it has passed the dwell time.

- Alarm relay turns on when it has passed the alarm dwell time.

- When Alarm Latch Type is in "ON" mode and alarm function runs, the alarm status and gas concentration

value stays (displayed) at the maximum value. When gas concentration decreases below the alarm

value, alarm does not get released and "RESET" key must be ran to release it.

- When Alarm Latch Type is in "OFF", Alarm is released automatically in accordance to gas concentration.

6.3. Mode Configuration

- When "FUNC" key is pressed for 2 sec or longer in measuring mode, it enters password required step.

- In a password required step, "PSWD" (Passwword mode) and password input display ([ - - ]) flashes

in turns with 0.5 s interval.

- Initial factory setting is ([ - - ]) = [00] and the password can be changed from ([00]~[99]). Entering

password followed by pressing FUNC (Function) key enters each mode. Using UP or DOWN key,

each mode can be selected.

- Using UP or DOWN key, it can enter internal mode.

- Internal mode can be set for CONF, PRGM, CALB, ALARM, etc.
