Fan Motor
In the installation option SEG 24, set the fan motor type.
1. In case of the fixed type setting
▶ Connect the PBA Fan out to the motor control signal.
▶ While the contact output for fan out is generated in contact closed, the contact output for fan out is not
generated in contact open.
2. In case of the variable type setting
▶ Connect the PBA H/M/L to the motor control signal.
▶ Depending on the fan out (H/M/L), the corresponding contact output is generated.
• Do not power the motor with the fan speed output contacts. If it is not the motor control signal
but the motor drive power, be sure to connect an external relay.
