Alarm
If an abnormality occurred in the speed controller or fan, the ALARM LED on the speed
controller blinks in red. Also, the alarm message can be checked by the indication level of
the indicator. If the fan was stopped, ensure safety before removing the cause of the alarm.
Alarm lists
Indicator
status Item Cause Remedial action Status of
fan
Stall
The fan was stopped.
Check the lifetime of
the fan or adherence
of a foreign particle.
Stop *1
There is no pulse
sensor output from the
fan.
Check if there is a
disconnection in the
lead wires of the fan.
Rotating
Overvoltage
The power supply
voltage exceeded
approximately 30 VDC. Check the power
supply voltage.
Stop *2
Undervoltage
The power supply
voltage fell below
approximately 18 VDC.
Overheat
The internal
temperature of the
speed controller
exceeded the specied
value.
Check the number of
units connected and
the operating ambient
temperature.
*1 The fan starts rotating when the cause that the fan has stopped is removed.
*2 The fan automatically starts rotating when the cause of the alarm is removed and the
power supply is turned on again.
z"Stall" alarm
The MD Series Vtype fans have a function of the pulse sensor output. The speed controller
can capture the pulse sensor output of the fan and output as the stall alarm if the fan
stops.
Inspection and maintenance
Inspection
It is recommended that periodic inspections for the items listed below are conducted after
each operation. If an abnormal condition is noted, discontinue any use and contact your

Regulations and standards
CE Marking
This product is axed the CE Marking under the EMC Directive.
zEMC Directive
This product has received EMC compliance under the conditions specied in "Example of
installation and wiring."
•Applicable Standards
EMI: EN 55011 group1 class A, EN 61000-6-4 EMS: EN 61000-6-2
Caution: This equipment is not intended for use in residential environments nor for use on a
low-voltage public network supplied in residential premises, and it may not provide
adequate protection to radio reception interference in such environments.
RoHS Directive
This product does not contain the substances exceeding the restriction values.
Installing and wiring in compliance with EMC Directive
FSC-24 has been designed and manufactured to be incorporated in equipment.
The EMC Directive requires that your mechanical equipment in which the product
is installed satises the applicable requirements. Installation and wiring methods of
FSC-24 explained here represent the basic methods that are eective in helping your
mechanical equipment conform to the EMC Directive. The nal level of conformance of
your mechanical equipment to the EMC Directive will vary depending on control system
equipment including FSC-24 and fans, conguration of electrical parts, wiring, layout,
and the like. It therefore must be veried through conducting EMC measures on your
mechanical equipment.
Without eective measures to suppress the electromagnetic interference (EMI) caused by
FSC-24 in the surrounding control system equipment and the electromagnetic spectrum
(EMS) generated by FSC-24, the function of your mechanical equipment may be seriously
aected. Implementing the following installation and wiring methods allows FSC-24 to
conform to the EMC Directive.
Ferrite core
When extending the cable, wind the cable around a ferrite core twice before use.
The ferrite core reduces the negative eects of external noise.
Use a ferrite core of the model ZCAT3035-1330 (TDK Corporation) or its equivalent. Install
the ferrite core as close as possible to the fan.
