3. Specication

GTD-5000F 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 flammable gases with vacuum construction and

to prevent accidents in advance. GTD-5000F 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).

1. Overview

GTD-5000F

Instruction Manual

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, PoE (Power over Ethernet) network signal, or Alarm signal.

5.5. Installation Cable Length [Figure 8. GTD-5000F Installation Cable Length Calculation]

■ The maximum length between GTD- 2000Tx and power supply is decided by wire specification.

■ Max. Installation Length = VMAXDROP ÷ IMAX ÷ WIRER/m ÷ 2

·VMAXDROP: Maximum Power Loop Voltage Drop

(=Power Supply voltage - min operating voltage)

·IMAX : Max. Current of GTD-2000ExW

·

WIRER/m: The resistance of the wire (ohms/meter value available in wire manufacturer's specification data sheet)

■ Example of installation lengths using 24 V power supply and 16 AWG is as follows.

·GTD-5000F minimum operating voltage = 18 V DC

·VMAXDROP = 24 - 18 = 6V

·IMAX = 0.55A ( 550mA )

·6 ÷ 0.55 ÷ 0.01318 ÷ 2 = 413.8502m ≒ 413m

Power cable installation for each cable type is as shown in the table below.

Instruction Manual 6. Operation6. Operation

6.1. Power On 6.2. Measuring Mode

■ 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 (IR-S: IR type Sensor, CT-S: Cartridge type Sensor), and sensor data are being loaded,

is displayed. After displaying "R180~R001", it enters measuring mode (for O2 sensor, it displays 1800~0001).

■

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.

- It is categorized into IR type sensor (IR-S) and cartridge type sensor (CT-S).

- 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 cartridge warm-up, it counts from R4~R1 then enters measuring mode.

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

- It displays gas concentration received from sensor cartridge on LCD digital display in numbers and the

current flow rate in bar graph.

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

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

- When input gas concentration from sensor cartridge 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.
