Resetting fault
Instructions for how to reset a fault can be found in paragraph 8.2.7.
Local/Remote control button
The LOC/REM button is used for two functions: to quickly access the Control page and to easily
change between the Local (Keypad) and Remote control places.
Control places
The
control place
is the source of control where the drive can be started and stopped. Every control
place has its own parameter for selecting the frequency reference source. In the HVAC drive, the
Local control place
is always the keypad. The
Remote control place
is determined by parameter
P1.15 (I/O or Fieldbus). The selected control place can be seen on the status bar of the keypad.
Remote control place
I/O A, I/O B and Fieldbus can be used as remote control places. I/O A and Fieldbus have the lowest
priority and can be chosen with parameter P3.2.1
(Rem Control Place)
. I/O B, again, can bypass the
remote control place selected with parameter P3.2.1 using a digital input. The digital input is se-
lected with parameter
(I/O B Ctrl Force)
.
Local control
Keypad is always used as control place while in local control. Local control has higher priority than
remote control. Therefore, if, for example, bypassed by parameter
(I/O B Ctrl Force)
through dig-
ital input while in
Remote
, the control place will still switch to Keypad if
Local
is selected. Switching
between Local and Remote Control can be done by pressing the Loc/Rem-button on the keypad or
by using the "Local/Remote" (ID211) parameter.
Changing control places
Change of control place from
Remote
to
Local
(keypad).

Anywhere in the menu structure, push the Loc/Rem button.
