CHAPTER 2 Checks and Preparation
2.19 Connecting the 4ch Voltage / Temperature Terminal (GS-4VT) (Optional)
For the specications of the 4ch voltage / temperature terminal, refer to the Instruction Manual supplied with
the sensor.
The connecting procedure between the GL840 and 4ch voltage / temperature terminal is described.
• Turn Off the GL840’s power.
• Connect rmly the 4ch voltage / temperature terminal’s connector to the GL840's GS sensor and terminal /
adapter connection terminal (GS-INPUT).
• Turn On the GL840’s power and make sure that the sensor settings are displayed on the AMP Setting
screen.
4. Connector
1. Hook portion
2. Input terminal
3. Logic / Pulse input terminal
GL840 main module
1. Hook portion ...................Used to mount to a wall.
2. Input terminal .................Used to connect voltage input or thermocouple.
3. Logic / Pulse input terminal ..Used to apply logic input.
4. Connector .......................Used to connect to the connector on the GL840 module.
Please do not use in a state in which only the 4ch voltage / temperature terminal is attached on a wall or
the like.
The damage of the connected cable and connector or the drop of the GL840 may be caused.
< Extension cable >
The module can be used approx. 1.5 m away from the GL840 by using an extension cable for GS (GS-EXC).
However, you cannot connect and use multiple extension cables.
