Power and Signal Terminal Configuration ■ After detaching the cover, the Main PCB terminal layout appears as shown in the figure below. ■ <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. Holding it with hands and pulling towards ceiling detaches it from the Main PCB. ■ Loosen 5 terminal fixing screws located at top part of detached terminal block CN8 (VIS, +, mA, -, ETH) Connector by turning ccw using a Θ driver. Connect DC 18~24 V power to +, and - then connect signal cable to mA. Tighten 5 terminal fixing screws clockwise (cw) so that terminal does not leave the track then insert Main PCB as the same condition before disassembly. - Page 8 Instruction Manual 14_15 5.4. Method to Connect to External Control Unit 5.5. Installation Cable Length ■ Connect 18 V~31 V DC operation power to CN1 (+, mA, -, ET) Connection Terminal of the gas detector then ■ The maximum length between GTD-2000Tx(2W) and power supply is decided by wire specification. connect a device that can receive 4~20 mA signals to mA. ■ 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-2000Tx(2W) ·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-2000Tx(2W) minimum operating voltage = 16 V DC ·VMAXDROP = 24 - 16 - 5.5 = 2.5V ·IMAX = 0.022A ( 22mA ) ·2.5 ÷ 0.022 ÷ 0.01318 ÷ 2 = 4,310.9 m ≒ 4310 m [Figure 7. Method to connect External Control Unit] [Figure 7. Calculation of GTD-2000Tx(2W) Installation Cable Length] ■ Power cable installation for each cable type is as shown in the table below.
