• The AAR is controlled by a single analog input signal with two potentiometers controlling each output relay. The two 10 amp output relays can be independently set to fi¬xed or adjustable dead-band. “Fixed”, the relay will turn “ON” at the level set by the Low pot and will turn “OFF” at a fi¬xed 3% of the input signal below the turn-on level. “Adjustable” allows a flexible range of dead-band adjustment using both the High and Low potentiometer. The edge-connector feature allows signal and power connections to be extended to the next board. This allows the installer to wire the fi¬rst unit, then slide additional units together by plugging into a power, and signal bus without the need to strip and terminate additional wires. The AAR can be fi¬eld calibrated, however, factory calibration is available upon request for an additional charge. Relay trip points can be factory calibrated, saving installation time and expense.
