Alarm from frequency converter
When running frequency controlled fans, you sometimes want to use both a pressure signal from a
pressure transmitter and a digital alarm signal from a frequency converter. An analogue input for a
pressure transmitter and a digital input for "SAF Indication" or "EAF Indication" must then be
configured. The setting "Run indication/Motor protection SAF" or "EAF Indication" must be set to
"Motor protection". A fan alarm will be activated both when there is no pressure signal from the
pressure transmitter, and when the digital signal "SAF Indication" or "EAF Indication" is activated.
17.23 Actuator type
Choose output signals to the actuators connected to the analogue control outputs: 0…10 V DC,
2…10 V DC, 10…0 V DC or 10…2 V DC.
Actuator type
Y1 heating: 0-10V
Y2 exchan.: 0-10V
Y3 cooling: 0-10V
Actuator type
SAF: 0-10V
EAF: 0-10V
Split: 0-10V
Actuator type
Humidity: 0-10V
Extra unit: 0-10V
Y1 Heat/Y3 cool 0-10V
Actuator type
Y4 extra seq: 0-10V
Actuator type
Y5 extra seq: 0-10V
NOTE: Even though many manufacturers state 0…10 V DC as control signal for many actuators,
the actual control signal is more often than not 2…10 V DC. Check the actuator documentation
carefully. If uncertain, choose 0…10V DC. Although control might be less accurate, it will ensure
that the valve always can be driven to its fully opened and fully closed positions.
17.24 Running time, 3-position actuators
These parameters have no function if analogue actuators are configured.
The values are used to determine the control parameters for 3-position actuators.
It is important to set correct values since incorrect values lead to sloppy control.
Actuator run time
Heating: 255 s
Exchanger: 255 s
Cooling: 255 s
