Malfunctions

Analogue and digital
•
When overloaded, the I-fan will adjust itself back on the basis of maximum power. If the RPM is lower than 93%
of the maximum RPM, an alarm will sound.
•
For other malfunctions, the I-fan will start itself up again independently after a short while. If the motor does not
start up then, the alarm relay will be switched off. If the I-fan no longer starts independently, the I-fan must be
removed from power for at least 30 seconds and then be started up again.
Digital
•
If I/O communication is interrupted, the last set value remains active.
•
Turning the power supply on and off without I/O communication will activate the predefined setting of dipswitch
8 (ON=50%, OFF=100%, see also page 7).

Maintenance

The I-fan requires no specific maintenance. Fancom recommends that your installation technician inspects the
complete climate installation, of which the I-fan is a component, every half-year.
Inspect the I-fan periodically for any damages. Notify your installation technician immediately of any
damages. A damaged I-fan is unsafe!
Check the I-fan for proper functioning regularly.
There must always be power to the I-fan. This prevents the formation of condensation in the I-fan. When
the mains power is interrupted, the alarm relay is also interrupted.
Gndfi
If the I-fan is controlled via the I/O network, this can be
bridged with a manual control via the -10V input. In this
case, both the I/O network and the 0-10V are connected. A
manual control has the following positions:
•
AUT : (0-1V) automatic regulation via the I/O network
•
OFF : (1-1.5V)
•
MAN : (1.5-10V) manual regulation (continuous) via
manual control
