Table 14.9.1. Relationship between the input voltage and fan speeds (digital outputs).
Voltage output AO2 from the C35-FC is applied to the FC-RB analog input 2 (AI2). Analog input
2 (AI2) controls the digital output 4 (DO4) with Pulse Width Modulation (PWM). If this voltage
is 7.5V, or 75% of the maximum 10V value, then the DO4 will set the electric valve actuator to
75% open. In the same manner, voltage output 3 (AO3) from C35-FC controls the digital output
5 (DO5) through analog input 3 (AI3) on FC-RB.
