5.3. Power and 4-20mA Terminal Configuration
■ <Warning - Turn off power before connecting power terminal>
■ After detaching the display part, 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 counter-clockwise using a Θ driver. Connect DC 18~24 V power to +, and - then connect
signal cable to mA. Tighten 5 terminal fixing screws clockwise so that terminal does not leave the track then insert
Main PCB as the same condition before disassembly.

■ Use CVVS or CVVSB 2.0sq↑ Shield Cable for terminal configuration.
■ To connect 4 Pin terminal from the existing old GTD-2000Tx model, connect terminals in reference to pin #2,
which is +24V.
5.3.1. Wiring for 4~20mA Source Operation Type
5.3.2. Wiring for 4~20mA Sink Operation Type
■ Connect 4-20 mA signal terminal at PLC side to 'mA'
of GTD-3000TxW. 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 'mA' terminal,
respectively. Then, turn off the J1 jumper.
■ HART Communicator can only be used in models
using HART Option board
