5. Installation www.gastron.com 10_11 It is prohibited for an individual, other than an approved user or a technician responsible for installation and repair from the head office, to install a gas leak detector on site or open the cover of the installed gas leak detector and manipulate it.
GTD-3000Ex 5. Installation Instruction Manual 5.2. Main PCB Configuration ■ After detaching the display parts, the Main PCB terminal layout appears as shown in the figure below. [Figure 5. Main PCB Terminal Layout] NAME DESCRIPTION CN11 Power & Output Signal Terminal CN10 Alarm &...
5. Installation www.gastron.com 12_13 5.3. Power and 4-20mA Terminal Configuration ■ <Warning - Turn off power before connecting power terminal> ■ After disassembling display parts, there is a terminal block in the Main PCB as shown in the figure below.
5.3.1. Wiring for 4~20mA Source Operation Type ■ Connect 4-20 mA signal terminal at PLC side to 'mA' of GTD-3000Ex. GND terminal is used in common with power. Then, turn on the J1 Jumper. ■ HART Communicator can only be used in models using HART Option board.
■ Connect (+) and (-) terminals for 4-20 mA sink output at PLC side to VISO terminal and power (24V DC) (-) terminal, respectively. Connect‘mA’terminal of GTD-3000Ex to‘GND’ terminal. Then, turn off the J1 Jumper. [Figure 9. 4-20mA 3Wire Sink Configuration] 5.4.
5.4.2. Relay Mode Configuration [Figure 11. Relay Mode Setting] ■ Relay of GTD-3000Ex operates in 2 types of method; Normal open and Normal close. The Jumper is constructed to configure relay operation method at the Main PCB and operating setting is as follows.
16_17 5.5. Installation Cable Length ■ The maximum length between GTD-3000Ex 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.
GTD-3000Ex 6. Detector Operation Flow Instruction Manual 6.1. Initial Operation Status (Power On) ■ After wiring to power terminal at the top of Main PCB board then supply power, the following contents are displayed on LCD. Approx. 30 m of stabilization of time is needed from the initial supply of operation power and it starts to operate normally after sufficient stabilization.
■ When“RESET”key contacts at Program Mode Screen, it returns to Measuring Mode. When "RESET" key contacts at each Program Setting Screen, it returns to the parent step. [Figure 13. GTD-3000Ex Mode Configuration] ■ Operation keys for detector system mode are defined as below.
