English
The FC hand terminal is used to set FC
frequency converters. With the hand terminal,
the frequency converter parameters can be
adjusted to the fan concerned. Changed
settings can be stored in two different user
setups, and it is possible to recall the original
factory settings, which cannot be changed. The
frequency converter can be remotely controlled
while operating values such as frequency,
current and output can be read on the hand
terminal display.
PRODUCT PROGRAMME
Type
FC-HTERM
Hand terminal for FC frequency
converters
FUNCTION
The hand terminal communicates directly with
the FC frequency converter by means of
Modbus commands. Factory and user setups
are stored in the frequency converter, and the
settings will be remembered even if the power
supply or hand terminal is disconnected. If the
hand terminal is not used for more than 10
minutes, it will automatically revert to the main
menu so that the risk of incorrect operation is
reduced. Possible settings and displays appear
from Table 1.
By turning the hand terminal button, it is
possible to scroll upwards or downwards
through the menus. Selections are made by
pressing the button. Selected values are
changed by turning the button. Menus are
exited by pressing the button.

INSTALLATION
The FC hand terminal can be positioned in the
accompanying wall bracket (fig. 2), which must
be fitted on a plane surface.
The hand terminal is removed from the wall
bracket by pushing the terminal upwards and
then pulling it out.
CONNECTION
Connect the hand terminal to the FC frequency
converter by means of a bus cable fitted with an
RJ12/6 connector at each end (fig. 3).
In the frequency converter, set the jumper "Ext.
Supply" as illustrated in fig. 3. For further
information on the frequency converter, please
refer to the FC instruction manual.
LED indication
The hand terminal has two LEDs (fig. 4), which
indicate the following:
On
Flashing
Red LED
Alarm active
Green LED
OK
Override by means of hand
terminal
Alarms
Current alarms are read as shown in Table 1.
Alarms are automatically reset if the alarm
situation passes, and the frequency converter
restarts. However, once the maximum number
of restarts has been exceeded, the alarm must
be reset by selecting "Reset Alarm" in the alarm
menu. Alternatively, the "Alarm reset" input can
be short-circuited to ground (fig. 5) or the
supply voltage disconnected.
