Mode 1:
+28 VDC on J1-A turns the blower on at 1500±100 RPM. When the air temperature sensor reaches 76.7±3° C (170±5° F), the speed switches to 3000±200 RPM. The blower switches back to 1500±100 RPM when the temperature drops to 68.3±3° C (155±5° F). If the air temperature sensor fails, the blower defaults to the 3000 RPM speed.
Mode 2:
If J1-A optocoupler is off, the blower speed is controlled by PWM (Pulse Width Modulation) signal on J2-A as specified in PWM IN.

The magnitude is the same as input voltage
OFF = < 1mA current flow through J1-A optocoupler input
On = > 5mA current flow through J1-A optocoupler input.

The magnitude is the same as input voltage
Frequency: 1.8 kHz
Speed Control Range: 600 to 3000 RPM
100% Duty Cycle = 3000±200 RPM
60% Duty Cycle = 1800±120 RPM
20% Duty Cycle = 600±40 RPM
0% Duty Cycle = 0 RPM (Off) |
