Front Panel Indicators:

Relay On		Indicates when relay is energized

Fault		Indicates a self-test error or fault condition

Setpoint		Adjusts the set point

Max		Used to adjust the range of the Thermal Signal display from MIN to MAX

Thermal Signal		The amount of thermal energy dissipated by the process for a given range


	The Thermal Signal increases as:

	Flow		The flow rate increases

	Level		The sensor is submerged

	Interface		The sensor is submerged by the second distinctly different process

Electrical Connections:
To assemble the electrical connections to the BASIC, it is necessary to remove the electronics module by using the following steps:

1.		Remove the cover by first turning the external stainless steel locking screw clockwise with a 5/32" Allen Key and then turning the cover counterclockwise.

2.		Observe proper ESD (Electro Static Discharge) handling procedures when removing, handling and storing the electronics module. Electrostatic discharge may damage the electronics! Never place the electronics module on a surface or pass it to another person in a way that would allow an electrostatic discharge to pass through it.

3.		To remove the electronics module, unscrew (counterclockwise) the 2 plastic knobbed fasteners then pull on both evenly and upwards. Be careful with the sensor cable that is attached to the bottom of the electronics module.

4.		Once the module is removed, disconnect the sensor cable by pushing on the black release lever and gently pulling (with fingers) on the corners of the small black connector. Do not pull on the wires. The use of pliers may damage the connector.

5.		Once the module has been removed, you can make the electrical connections to the bottom of the BASIC electronics module as required.

6.		To replace the electronics module in its enclosure, repeat steps 1 through 6 in reverse order. The cable from the sensor to the module can be gently placed between the outside of the two mounting posts located on the inside of the enclosure.
