BUILDING AUTOMATION

Parameter “Fan operation mode”

This parameter defines the operating mode of the fan and needs to be considered in conjunction with the technical characteristics of the fan. Options:

Changeover switch

Step switch

Changeover switch: It can set the delay time of fan speed changeover, see next parameter.

This type of control can switch the fan speed to any level, such as directly switching from the first level fan speed to the third stage fan speed, but in any case,

the three channels have only one output.

Step switch: Under this control type, the 3rd-level fan speed is equivalent to the superposition of three one-level fan speeds. For example, when the 3rd-level

fan speed is used, all three channels output simultaneously (such as Output 1&2&3). When the 2nd-level fan speed is used, 2 channels output at the same time

(such as Output 1&2).

Note: This parameter must be considered in conjunction with the technical parameters of the fan.

Parameter “Delay between fan speed switch [50…5000]ms”

This parameter is visible when the operating mode is selected as “changeover switch” and is used to define the conversion delay, which is a specific element of

the fan and should be considered in all cases. Available options:

50...5000

When a fan speed converted telegram is received, the target fan speed will be performed after the delay has elapsed.

If the device receives a new fan speed during the switching delay, the delay time will not be interrupted, but the last received fan speed is executed.

Parameter “When bus failure, Fan speed is”

This parameter notes the action of the fan when the bus is powered down. Options:

Unchange

OFF

OFF: Turn off the fan;

1, 2 or 3: The fan is turned on to fan speed 1, 2 or 3.

Note: If the fan speed is limited to 2, while the parameter selects 3, the fan speed after power failure will maintain the fan speed before power failure.

Parameter “When bus recovery, fan speed is”

This parameter defines the action of the fan after the bus voltage is recovered. Options:

Unchange

OFF

As before as bus fail

OFF: Turn off the fan.

1, 2 or 3: The fan is turned on to fan speed 1, 2 or 3.

As before as bus fail: The fan speed is the same as the speed before the bus is powered down.

Note: Before connecting the fan, in order to obtain a defined fan switch status, it is recommended to connect the bus voltage first to avoid the pos-

sibility of damage to the fan due to incorrect connections. If the parameter 3 is selected in the case of limiting the 2nd fan speed, the fan speed after

the reset does not change.

Parameter “After downloading, fan speed is”

This parameter indicates to turn off the fan after the application is programmed.
