Page 8: Getting To Know The Gl400
Chapter 1 Getting to Know the GL400 The GL400 is enclosed in a UV protected PVC weather-resistant enclosure. The COM port can connect to a PC se- rial port using the included Communica- tion Cable. COM port Access the included 12V, 2 AH lead acid gell cell directly from inside enclosure. - Page 9 Introduction attach cable wires to terminals Connect sensors to the GL400 by threading sensor cables through the enclosure’s strain reliefs (8 on the GL400-7-1 and 2 on the GL400-1-1) and attaching cable wires to the channel terminals. GL400-7-1 GL400-1-1 Each end of the Communication Cable is identical. Connect one DB-9 fe- male connector to your PC and the other to your Datalogger.

Sensors are calibrated to a variety of unit specifications (i.e. meters, percent, etc.), so your bar graph readings may differ slightly. Note that the GL400 terminal strip can only accommodate seven analog sensors, so one channel will not be used.

Global Water recommends that the battery voltage be physically checked based on your recording interval*. Refer to the following table. Note, that the GL400 uses 160µA while “sleeping” and 10mA plus the signal current while taking readings. This table is based on the worst-case scenario where all sensors are providing the maximum signal of 20mA. -

Page 41: Appendix E: Alternate Power Sources
The battery that was included with the GL400 will operate in parallel with the external. Thus, a supplemen- tal 12V source, such as a solar panel, may be added to increase the battery life. If this method is chosen the external source must be diode protected from the battery voltage.
