0-04 Operating State at Power-up (Hand)
Option:
Function:
Select the operating mode upon reconnection of the frequency
converter to mains voltage after power down when operating in
Hand (local)mode.
[0]
*
Resume
Resumes operation of the frequency converter maintaining the
same local reference and the same start/stop condition (applied
by [Hand On]/[Off] on the LCP or Hand Start via a digital input
as before the frequency converter was powered down.
[1]
Forced stop, ref=old
Uses saved reference [1] to stop the frequency converter but at
the same time retain in memory the local speed reference prior
to power down. After mains voltage is reconnected and after
receiving a start command (using the LCP [Hand On] button or
Hand Start command via a digital input) the frequency converter
restarts and operates at the retained speed reference.
2.2.3. 0-1* Set-up Operations
Define and control the individual parameter set-ups.
The frequency converter has four parameter setups that can be programmed independently of
each other. This makes the frequency converter very flexible and able to meet the requirements
of many different AQUA system control schemes often saving the cost of external control equip-
ment. For example these can be used to program the frequency converter to operate according
to one control scheme in one setup (e.g. daytime operation) and another control scheme in an-
other setup (e.g. night set back). Alternatively they can be used by an AHU or packaged unit OEM
to identically program all their factory fitted frequency converters for different equipment models
within a range to have the same parameters and then during production/commissioning simply
select a specific setup depending on which model within that range the frequency converter is
installed on.
The active setup (i.e. the setup in which the frequency converter is currently operating) can be
selected in parameter 0-10 and is displayed in the LCP. Using Multi set-up it is possible to switch
between set-ups with the frequency converter running or stopped, via digital input or serial com-
munication commands (e.g. for night set back). If it is necessary to change setups whilst running,
ensure parameter 0-12 is programmed as required. For the majority of AQUA applications it will
not be necessary to program parameter 0-12 even if change of set up whilst running is required,
but for very complex applications, using the full flexibility of the multiple setups, it may be required.
Using parameter 0-11 it is possible to edit parameters within any of the setups whilst continuing
the frequency converter operation in its Active Setup which can be a different setup to that being
edited. Using parameter 0-51 it is possible to copy parameter settings between the set-ups to
enable quicker commissioning if similar parameter settings are required in different set-ups.
0-10 Active Set-up

Function:
Select the set-up in which the frequency converter is to operate.
