19 Controls Capability (cont.) (1) The controller is programmed with minimum and maximum temperature setpoints. The current output (and resulting fan speed) will be proportional to the highest input temperature over this temperature range. The full temperature range of each sensor and the desired minimum and maximum setpoints must be specified. (2) Factory set per OEM specifications. (3) The controller will give priority to the input that requires the fan to operate at the higher speed. This priority is factory set and must be specified by the OEM. (1) Provide sensor data sheet with complete specifications. (2) Liquid temp. sensor for engine coolant, liquid temp. sensor for hyd. oil, air temp. sensor for charge air, etc. Technical Specifications Temperature Sensor Inputs Contact Concentric with OEM specific sensor input requirements. The controller ramps output over a factory set value. Specify ramp rates, if other than factory settings. See specification requirements in table below. MinimumTemperature Setpoint MaximumTemperature Setpoint Temperature Sensor Input 1 (1), Sensor Input 2 (1), and Sensor Input 3 (1) Available (2) Available (2) Digital Input 1 (3) and Digital Input 2 (3 ) Ramps output over a 2.5 second period. Specify, if other ramp time required. Specification Information Required Power supply voltage (12 or 24 VDC): Digital (on/off ) inputs (Active high is standard.
