2000-CAL hand held calibrator is used. Only the integral DIP switch / pushbutton user interface
procedure is described here. See the 2000-CAL hand held calibrator manual for details if using it instead.
3.3 USING THE DIP SWITCH FOR SETUP AND CALIBRATION
Note: all of these settings are preset at the factory as per the customer requirements.
These settings are listed on the packing slip and may be entered in the controller
setting of this manual for future reference. The following procedures should only be
followed if changes are required.
3.3.1 ENTERING SETUP MODE
Set DIP switches 1-6 (switch 7 is not important here) to the ON position, and press the
Calibration pushbutton. The Status LED starts to blink Green indicating the system is now
ready to accept configuration changes.
3.3.2 SETTING CONFIGURATION
1. While the Status LED is blinking green, set the DIP switch as follows:
2. Self Test Feature
: If the sensor is for Carbon Monoxide and supports the self test
feature, then set switch 4 to the On (up) position, else set it to the off (down) position.
3. Single Point / Dual Point Calibration
: The default position is Single Point Calibration.
A Single Point calibration assumes the instrument has already been zeroed
successfully. This mode saves calibration time. The Dual Point calibration is selected
if the sensor has not been successfully zeroed, or if a new sensor is installed in the
field. Set switch 5 On (up) for Single Point and Off (down) for Dual Point calibration.
4. Output Mode
: In Analog output mode, the output is proportional to the gas
concentration. In Discrete Voltage Output mode, the output is set to one of 4 step
values based on alarms and is compatible with Arjay’s ISA 66RLU/Gas-Alert systems.
Notes:
• Wire connections to the OUT terminal are dependent on the type of Output
mode selected.
• When configured for mA out, the transmitter does not become a 2 wire Loop
Powered transmitter. The mA output is referenced to the Ground terminal
(Terminal #2 –see Electrical installation for terminal number details).
For Analog output
, switch 6 should be On (up) and switch 7 should either be Off
(down) for 4-20mA output, or On (up) for voltage output (2V – 10V).
For RLU Discrete Voltage output
, switch 6 should be in the Off (down) position, and
switch 7 should be in the On (up) position.
Note: Switch 7 acts immediately and does not require configuration mode to be
entered, or the Cal pushbutton to be pressed to take effect. It can be changed at
any time.
