Error Peak current
If the motor current increases above the
specified limit (even in a short time-
frame) the device will switchoff.
After a switch off the controller waits for 5 seconds then the
controller attempt a start.
Arises within 60 sec. in series 5 further disconnections a final
switch off with fault indication follows.
Should no further switch off be exceeded in 60 sec. the counter
will be reset.

Add-on modules
If required, an auxiliary module can be retrofitted to the designated slot for motor size “D”, “G”. The extended scope of function is specified in the
documentation for the auxiliary module.
349046 Premium Module
When the auxiliary module is plugged in the controller in the fan is extended to become a full-grade multipurpose controller. For example, “Premi-
um module” provides not only an integrated MODBUS interface, it also enables sensors to be connected straight to the fan.
The module also comes with two analogue inputs and one analogue output.
Mounting the module:
Danger due to electric current
• Always read the safety instructions chapter before mounting!
• The fan in which the module is to be installed must be disconnected from the line voltage for at least 3 minutes before opening!
Attention, electrostatic sensitive devices!
• Damage to electronic components by electrostatic charging must be prevented!
• Touch the protective earth connection in the terminal to equalize the potential immediately before removing the module from the packing. This
applies regardless of whether the device is already connected to the line.
• Equalize the potential again shortly before installation if the module is not installed immediately after unpacking.
• After unpacking the module, check for possible transport damage and insert it in the slot provided. Do not touch the connection!
Procedure:
Mount the module in the housing with the two enclosed screws (permissible tightening torque MA =1.3 Nm)

NOTE: For more information, control, maintenance, diagnostics and troubleshooting refer to EC motors and Add-on modules technical
specification.
FanWall
For bigger air handling units, where more air flow is needed, fan wall can be selected (from 2 to 20 EC fans).
Control types for EC fan wall:
• Control with EMR’ex
No additional add-on modules are needed.
All fans are controlled with 0-10V signal.
