3.1 NOTES ON THE USER INTERFACE OPTIONS
The EC-Gold may be configured and calibrated using either of 2 methods:
1. Using the integral DIP switch and Calibration pushbutton. The EC-Gold front cover must be
removed to access the DIP switch. For calibration only, the pushbutton is accessible without
removing the front cover.
2. Using Arjay’s optional 2000-CAL hand held calibrator. The calibrator communicates with the EC-
Gold via the RS-485 connection using the modbus protocol. The calibrator’s LCD and keypad
offer a more convenient method of setting up and calibrating the EC-Gold unit.
3.2 STARTUP
Power up the unit. The status LED should be green. The High and Low alarm LED’s should go off in
less than a minute.
The unit is normally pre-configured and calibrated at the factory so field setup is not required on
startup.
To check calibration, or to re-enter / modify settings, follow the procedures described below. The method
used will depend on if the integral user interface is used (DIP switch / pushbutton) or if the Arjay/Enmet
