1.0 introduction
This document contains specific information regarding the
safe installation, operating and maintenance of the Armstrong
Design Envelope pumps and should be read and understood by
installing, operating and maintenance personnel. The equipment
supplied has been designed and constructed to be safe and
without risk to health and safety when properly installed, oper-
ated and maintained. The instructions following must be strictly
adhered to. If clarification is needed on any point please contact
Armstrong quoting the equipment serial number.
1.1 instructions for safe use
No installation of this equipment should take place
unless this document has been studied and under-
stood. Handling, transportation and installation of this
equipment should only undertaken by trained personnel with
proper use of lifting equipment. See later diagrams for lifting ad-
vice. Refer to the pump nameplate for pump speed, pressure and
temperature limitations. The limits stated must not be exceeded
without written permission from Armstrong.
1.2 temperature
Install the Design Envelope unit with adequate access
for routine maintenance. Adequate space, particularly
at the fan inlet 2" (50 mm), is necessary to facilitate
airflow. Where several Design Envelope units are installed in
close proximity, care must be taken to ensure that there is no
re-circulation of exhausted warm air.
Where under normal operating conditions the limit of
68°c/155°f(Restricted Zone) for normal touch, or 80°c/176°f
(Unrestricted Zone) for unintentional touch, may be experi-
enced, steps should be taken to minimize contact or warn opera-
tors/users that normal operating conditions will be exceeded.
In certain cases where the temperature of the pumped liquid
exceeds the above stated temperature levels, pump casing tem-
peratures may exceed 100°c/212°fand not withstanding pump
insulation techniques appropriate measures must be taken to
minimize risk for operating personnel. The ambient temperature
for standard motors must be no greater than 40°c/104°f.

1.5 storage
Pumps not immediately placed into service, or removed from
service and stored, must be properly prepared to prevent exces-
sive rusting. Pump port protection plates must not be removed
until the pump is ready to connect to the piping.
Rotate the shaft periodically (at least monthly) to keep rotating
element free and bearings fully functional.
For long term storage (longer than three months), the pump
must be placed in a vertical position in a dry environment.
Internal rusting can be prevented by removing the plugs at the
top and bottom of the casing and drain or air blow out all water
to prevent rust buildup or the possibility of freezing. Be sure to
reinstall the plugs when the unit is made operational. Rustproof-
ing or packing the casing with moisture absorbing material and
covering the flanges is acceptable. When returning to service be
sure to remove the drying agent from the pump.
1.6 uncrating
Armstrong Vertical In-Line pumps are thoroughly inspected be-
fore shipment to assure they meet with your order requirements.
After removing the pump from the crate, make sure the equip-
ment is in good order and that all components are received as
called for on the packing list. Any shortages or damage should
be reported immediately. Use extreme care in handling the
unit, placing slings and hooks carefully so that stress will not be
imposed on the integrated controls, pump or motor. Never place
cable slings around the pump shaft or integrated controls. The
eye bolts or lifting lugs on the motor are intended for lifting only
the motor and not the complete unit.
1.7 handling design envelope 4300 & 4380 units
To handle Design Envelope 4300 and 4380 units from shipment,
secure the pallet following uncovering the unit, then placestraps
behind the integrated controls (around the motor feet) and
carefully lift the pumping unit to stand the pump vertically up-
right.Lift only suciently to remove the pallet, then lower onto a
flat surface. The pump and motor unit will free-stand on the cas-
ing ribs.Extra care is required to ensure the integrated controls
do not get damaged during lifting and installation.
For Design Envelope 4300 units, remove the coupling guard and
insert lifting straps through the pump/motor pedestal on either
side of the coupling. For Design Envelope 4380 units, remove
the motor eye-bolt and install a swivel hoist ring tied to a lifting
strap. Place secondary lifting straps around the motor feet (and/
or spacers). As the lifting device is engaged (Using a spacer bar
if necessary) and the straps tighten ensure no part of the strap-
ping is touching any part of the control or motor fan cover. Lift
the pumping unit carefully from the pallet in this manner and al-
low the unit to stand upright on a flat surface and re-position the
straps, if necessary, to ensure safe and damage-free transporta-
tion into the pipe installation.

important:
Do not run the pump for any length of time under very
low flow conditions or with the discharge valve closed.
To do so could cause the water in the casing to reach
super heated steam conditions and will cause premature failure
and could cause serious and dramatic damage to the pump and
surrounding area.
2.0 installation
2.1 location
In open systems, locate the unit as close as practical to the
liquid being pumped, with a short, direct suction pipe. Ensure
adequate space is left above and around the unit for operation,
maintenance, service and inspection of parts.
In closed systems, where possible, the pumps should be in-
stalled immediately downstream of the expansion tank /make-
up connection. This is the point of zero pressure change and is
necessary for eective pump operation. Do not install more than
one expansion tank connection into any closed hydronic system.
Electric motor driven pumps should not be located in damp or
dusty location without special protection.
Airflow into the motor and/or motor fan should not
be obstructed.
2.2 installation
When installing vertical in-line pumps, an important consider-
ation to accrue full added-value from the pump design is to en-
sure that the pump is pipe-mounted and free to ‘float’ with any
movement, expansion and contraction of the piping. Should any
vertical in-line pump use supports to the structure it is impera-
tive that no pipe strain is imposed on the pump flanges. Tell-tale
pieces of equipment such as springs or ‘wae’ style neoprene
isolation pads that distort with pressure to indicate added piping
weight, should be used under pump supports should the pump
not be truly pipe mounted.
Design Envelope 4300 and 4380 cannot be mounted with shafts
in the horizontal position.
Various installation arrangements are detailed on Pages 9–12
All Design Envelope 4300 pumps contain a tapped hole in the
motor bracket above the discharge flange to drain condensate
buildup of seal leakage. (fig. 2.14)
2.2.1
Vertical In-Line pumps may be installed directly in the system
piping with no additional support. Pipe hangers are simply sized
for the additional weight of the pumping unit. Many pumps are
installed in this manner and can be mounted at sucient height
to take zero floor space. (fig. 2.1)
2.2.2
Piping in many mechanical rooms is hung close to the ceiling
and larger pumps are mounted near ground level for ease of
maintenance. fig. 2.2 illustrates such an arrangement with the
piping supported at the ceiling and the vil unit installed with an
Armstrong Suction Guide and Flo-Trex valve. Many very large
vil pumps are installed in this manner.
2.2.3
Should additional space saving be required the discharge spool
piece may be replaced by a long-radius elbow.
2.2.4
fig 2.4 illustrates a similar arrangement to fig 2.2 with
additional floor mounted pipe-stools isolated from the structure
by ‘wae’ style neoprene isolation pads under the Armstrong
Suction Guide and Flo-Trex valve.
2.2.5
Floor mounted saddle supports (fig. 2.5)are typical for condens-
er water pumps where cooling tower base is at the mechanical
room elevation.
2.2.6
Where required, additional floor support may be used as shown
in Fig. 2.6. Note that the pump should not be rigidly attached to
the column. Leave a small gap between pump and column or
install a ‘wae’ isolation pad under the pump. It is critical that
piping be installed in such a manner that the pump does not
become a pipe support.

2.2.7
fig. 2.7 illustrates stanchion plates at the pump inlet and outlet
ports that may be supplied for installation convenience. Isolation
pads must be used under the legs and monitored as pipe hang-
ers are adjusted to ensure the pump flanges are not support-
ing the piping. Bolting to the floor or housekeeping pad is not
recommended. If the stanchions are bolted down the bolts must
be isolated from the stanchion or an inertia base and flexible
pipe connectors used.
2.2.8
fig. 2.8 illustrates installations with stanchion plates for seismi-
cally active regions. Seismically rated isolation pads or snubbers
with bolts isolated from the stanchion plates are installed to
restrain the pump during a seismic event. Pipe hangers carry the
weight of the equipment as seismic components are designed
only to restrain the equipment during a seismic event.
2.2.9
Many Vertical In-Line pumps are piped successfully into
grooved piping systems. In-line pumps are supported well by
grooved piping however flange adapter locking devices or a
welded flange at the pump should be used to prevent the pos-
sibility of pipe mounted pumps rotating in the piping. Armstrong
oers grooved suction guides with cast-in outlet flanges and
Flo-Trex valves with Armgrip™ fittings to prevent this
possibility. (fig. 2.9)
2.2.10
Do not support the unit by the motor eye bolts (fig. 2.10)or by
any other part of the motor.
2.2.11
Connecting the pump to a permanent rigid base (fig.2.11)is not
recommended unless isolated from the piping by flexible con-
nectors and the base isolated from the building structure on an
inertia base. (fig. 2.11 is generally acceptable when using
plastic piping).
2.2.12
The motor and integrated control assembly can be rotated in
90° increments to meet installation spacing requirements.
Where applicable, remove the coupling guard to access the
motor bolts.Remove the motor bolts to rotate the motor and
integrated control assembly by hand.Larger motors may need
strapping and slight lifting to break the contact with the ped-
estal.Care should be taken that the controls are not damaged
during lifting and that the flushline, flushline accessories and the
coupling guard removal/seal service window are not compro-
mised following the turn (fig. 2.12).vil pumping units without
integrated controls can also be rotated in a similar manner to
facilitate access to the the motor terminal box.
2.2.13
For d1 and d2chassis Design Envelope units (110 kW–315 kW),
ensure adequate space is available for the access door to swing
open. (fig. 2.13)
important:
All Design Envelope 4300 pumps contain a tapped hole in the
motor bracket above the discharge flange (see fig. 2.14) for
draining the well. Pipe this drain hole to a floor drain to avoid
overflow of the cavity caused by collecting chilled water conden-
sate or from seal failure.
2.3 pump piping – general
Never connect a pump to piping, unless extra care is taken to
measure and align the piping flanges well. Always start piping
from pump.
Use as few bends as possible and preferably long radius elbows.
Do not use flexible connectors on the suction or discharge of a
vertical in-line pump, unless the pump is rigidly mounted to a
foundation.
Ensure piping exerts no strain on pump as this could distort
the casing causing breakage or early failure due to pump
misalignment.
All conecting pipe flanges must be square to the pipework and
parallel to the pump flanges.
Suction and discharge pipes may be increased or decreased at
pump nozzle to suit pump capacity and particular conditions of
installation. Use eccentric reducers on suction connection with
flat side uppermost.
Layout the suction line with a continual rise towards the pump
without high points, thus eliminating possibility of air pockets
that may prevent the pump from operating eectively.
A strainer of three or four times the area of the suction pipe,
installed in the suction line, will prevent the entrance of foreign
materials into the pump. V" (3mm) diameter perforations in the
strainer is typical.
In open systems, test suction line for air leaks before starting;
this becomes essential with long suction line or static lift.
Install, at the pump suction, a straight pipe of a length equiva-
lent to four or six times its diameter; this becomes essential
when handling liquids above 120°f (49°c). Armstrong suction
guides may be used in place of the straight pipe run and
in-line strainer.
Install an isolation valve in both suction and discharge lines on
flooded suction application; these valves are used primarily to
isolate the pump for inspection or repair.
Install a non-slam non-return check valve in discharge line
between pump and isolation valve to protect pump
from excessive back pressure and to prevent water running back
through the pump in case of driver failure on open systems.

2.4 alignment
Design Envelope 4300 units are accurately aligned at the fac-
tory prior to being shipped and do not need re-aligning when
installed. Alignment on a Design Envelope 4300 unit may be
verified by assuring an equal and parallel gap between coupling
halves on both sides of the coupling.
operation
2.5 starting pump
Ensure that the pump turns freely by hand, or with
some gentle mechanical help such as a strap or Allen
key in coupling bolt.
Ensure that all protective guarding is securely fixed in position.
The pump must be fully primed on start up. Fill the pump
casing with liquid and rotate the shaft by hand to remove any
air trapped in the impeller. On Design Envelope 4300 any air
trapped in the casing as the system is filled must be removed by
the manual air vent in the seal flush line. Ensure entrained air is
removed from Design Envelope 4300 pumps, prior to starting,
through the air vent on the seal flush line. Open vent until clear
of air.
Design Envelope 4380 units are fitted with seal flush/vent lines
piped to the pump suction area. When these units operate,
residual air is drawn out of the pump towards the suction piping.
Bump or energize the motor momentarily and check that the
rotation corresponds with the directional arrow on the pump
casing (clockwise when viewed from drive end.).
Start the pump with the discharge valve closed and the suction
valve open, then gradually open the discharge valve when the
motor is at operating speed. The discharge valve may be
cracked or open slightly at start up to help eliminate trapped air.
When stopping the pump: Close the discharge valve and de-
energize the motor.
Do not run the pump against a closed discharge valve for an
extended period of time (a few minutes maximum.)
Should the pump be noisy or vibrate on start-up a common
reason is overstated system head. Check this by calculating the
pump operating head by deducting the suction pressure gauge
value from the discharge gauge reading. Convert the result into
the units of the pump head as stated on the pump nameplate
and compare the values. The system designer or operator
should be made aware of this soon as some adjustment may be
required to the drive settings to make the pump suitable for the
system as installed.
Check rotation arrow prior to operating the unit.
The rotation of all Armstrong Vertical In-Line units is
“clockwise” when viewed from the drive end.
(Looking from on top of/behind the motor).
2.6 general care
Vertical In-Line pumps are built to operate without periodic
maintenance, other than motor lubrication on larger units. A
systematic inspection made at regular intervals, will ensure
years of trouble-free operation, giving special attention to
the following:
• Keepunitclean
• Providethemotorwithcorrectlysizedoverloadprotection
 Keepmoisture,refuse,dustorotherlooseparticlesawayfrom
the pump and ventilating openings of the motor.
• Avoidoperatingtheunitinoverheatedsurroundings
(Above 100°f/40°c).
warning:
Whenever any service work is to be performed on
a pumping unit, disconnect the power source to the
driver, lock it o and tag with the reason. Any
possibility of the unit starting while being serviced
must be eliminated.
If mechanical seal environmental accessories are
installed, ensure water is flowing through the sight
flow indicator and that filter cartridges are replaced
as recommended. (See Armstrong files 43.85 and
43.86 for seal environmental instructions).

2.7 lubrication
Pump
Lubrication is not required. There are no bearings in the pump
that need external lubrication service.
Large Design Envelope 4300 units are installed with a shaft
bushing located beneath the impeller that is lubricated from the
pump discharge.
Motor
Follow the lubrication procedures recommended by the mo-
tor manufacturer. Many small and medium sized motors are
permanently lubricated and need no added lubrication. Gener-
ally if there are grease fittings evident the motor needs periodic
lubrication. None if not.
Check the lubrication instructions supplied with the motor for
the particular frame size indicated on the motor nameplate.
Mechanical Seal
The mechanical seal is fitted with a flush line. The seal is flushed
from discharge of the pump casing on Design Envelope 4300
pumps and from the suction on Design Envelope 4380 pumps.
The Design Envelope 4300 pump is flushed from the pump
discharge because the mechanical seal chamber is isolated from
the liquid in the pump by a throttle bushing. Because the seal
chamber is isolated, seal environmental controls such as filters
and separators, when installed in the Design Envelope 4300
flush line are very eective, as only the seal chamber needs
cleansing, and will prolong seal life in hvac systems.
Do not run the pump unless properly filled with water as the
mechanical seals need a film of liquid between the faces for
proper operation.
Mechanical seals may ‘weep’ slightly at start-up. Allow the
pump to continue operating for several hours and the mechani-
cal seal to ‘seat’ properly prior to calling for service personnel.
The following Armstrong files are available for mechanical seal
replacement instructions:
• Series4300: tc Motor Frame – File 43.88
• Series4380: File 43.81
2.8 system cleanliness
Before starting the pump the system must be thoroughly
cleaned, flushed and drained and replenished with clean liquid.
Welding slag and other foreign materials, ‘Stop Leak’ and clean-
ing compounds and improper or excessive water treatment are
all detrimental to the pump internals and sealing arrangement.
Proper operation cannot be guaranteed if the above conditions
are not adhered to.
note:
Particular care must be taken to check the following before the
pump is put into operation:
aPump primed?
b RotationOK?
c LubricationOK?
dPipe work properly supported?

3.0 ce conformities
For Declaration of Conformity certificates please
contact Armstrong.
The Design Envelope product conforms to the requirements
in the following directive(s), standard(s) or other normative
document(s):
low voltage directive 2006/95/ec
emc directive 2004/108/ec
machinery directive 2006/42/ec
ecodesign directive 2009/125/ec
4.0 mechanical installation
Install the Design Envelope unit with adequate access for routine
maintenance. Adequate space, particularly at the fan inlet (50
mm), is necessary to facilitate airflow. Where several Design En-
velope units are installed in close proximity, care must be taken
to ensure that there is no re-circulation of exhausted warm air.
With reference to fig. 3, the pump should not be
installed with the inverter in the underside position.
This guidance pertains to all pump types and
overrides any instruction in the particular pump
Installation, Operation and Maintenance Instruction.
integrated controls
Power Rating 0.55 kW - 7.5 kW
4.1 enclosure rating
The standard enclosure rating for Design Envelope
pumps is ip55. If the pump is to be installed in a wet or
dusty environment then a higher enclosure rating may
be required (ip56 or ip66 option).
4.2 ambient temperature
To avoid the inverter unit getting overheated, the
ambient temperature is not to exceed 40°c and the 24
hour average temperature is not to exceed 35°c. If the
ambient temperature is in the range of 40°c - 55°c, a
reduction of the service life of the inverter part is to be expected.
5.0 electrical installation
All electrical connections should be carried out by a
qualified and authorised electrician in accordance with
local site regulations and the latest issue of the
iee regulations.
safety, risk of death
Before removing the inverter cover, the system must
be disconnected from the mains supply. After switch-
ing o wait for at least five minutes for the capacitors
to discharge before opening the cover.

caution
High voltage testing (Megging) of the motor / inverter
may cause damage to the electronic components and
therefore should not be carried out.
5.1 earth leakage current
Earth leakage current is primarily caused by the ca-
pacitance between motor phases and the motor frame.
The rfi filter contributes additional leakage current, as
the filter circuit is connected to earth through capacitors.
The size of the leakage current to the ground depends of the
following factors, in order of priority:
1Switching frequency
2Motor grounded on site or not
The leakage current is of importance to safety during handling /
operation of the Design Envelope pump if (by mistake) the
on-board inverter has not been earthed.
attention:
Since the leakage current is >3.5 mA (approx 4 -20 mA),
reinforced earthing must be established which is required if en
50178 is to be complied with. Never use elcb relays that are not
suitable for dc fault currents (type a).
If elcb relays are used, they must be:
• Suitable for protecting equipment with a direct current
content (dc) in the fault current (three-phase bridge rectifier)
•Suitableforpower-upwithshortchargingcurrenttoearth
•Suitableforahighleakagecurrent
5.2 earth leakage current
The number of starts / stops via the mains voltage must not
exceed one time per two mins.
If a higher number of starts / stops is required then the start/
stop digital input must be used (mains voltage directly
connected). This is the preferred method of starting and
stopping Design Envelope Pumps.
The three phase mains must be isolated before
performing maintenance of the pump.
5.3 additional motor protection
With the exception of supply fuses / mcb’s to protect the
installation, no additional overload or over-temperature
protection is required. Motor / inverter protection includes:
•Mainsphaseloss
•Overvoltage
•Undervoltage
•Overcurrent
•Shortcircuit
•Overtemperature
5.4 supply voltage
The supply voltage details can be found on the motor
nameplate. Please ensure that the motor is suitable for the
electrical supply on which it is to be used. The mains supply
for Design Envelope pumps is as follows:
3 × 380/400/415/440/460/480v ±10% Supply
frequency - 50/60hz
5.5 tools for installation

will determine the operation of the pump(see the section on
Control Modes).
• Terminal 1 - 4-20 mA input for a remote feedback device
(when Sensorless control is not used).
•Terminal 2 - 0-10v input for a reference signal (when
Sensorless control is not used).
•Terminal 3 - Digital input for a low water device (pump only
runs if input is ‘logic 1’) - factory linked with zero ohm resistor
to terminal 6.
• Terminal 4 - Digital input for pump start (pump enabled when
‘logic 1’).
•Terminal 5 - Digital input for pump mode (if left at ‘logic 0’
then pump will be in sensorless mode).
•Terminal 6 - 24v dc supply for terminals 3to 5(max 150 mA).
• Terminal 7 - 10v dc supply for terminal 2when used with a
potentiometer (max 15 mA).
•Terminal 8 - 0v for terminals 1to 7and 9.
•Terminal 9 - Digital output for ‘pump fault’ connection to bms
(voltage level will be 24v dc when pump has a fault).
attention:
Terminal 9is not a volt-free contact. Connection of an external
voltage will destroy the unit.
x102 Terminals - Pump Running
The x102 terminals provide a relay changeover contact for
identification of pump running.
Terminals 1 - 2will be made when the pump is running.

5.9.1 connection examples
There are many ways that an Design Envelope pump can be
configured. The following is some examples of the most
common control configurations.
i Sensorless Pressure Control - Connection Details
Design Envelope pumps are factory configured to be
connected as shown below. For a description of sensorless
pressure control please refer to the programming section.
ii Full speed overide
It may be required to run the pump at full speed without
automatic speed control (e.g. during system commissioning).
This can be achieved without programming changes by
making the control connections shown below.

iii Constant curve mode - bms speed control
Where the Building Management System is to be used for
speed control it is necessary to disable sensorless control
and provide the unit with a 0 - 10v dc speed reference signal.
As shown above, in Constant curve mode the pump will speed
up and slow down according to the voltage level of the reference
signal. On a unit configured for 50 hz pump speed the reference
signal is scaled (by default) so that 0v on x100 terminal 2will
equate to 0 hz and 10v will equate to 50 hz.
iv Constant curve mode - Potentiometer speed control
If a potentiometer is to be installed for manual control of
pump speed then the control connections will be as follows:
The recommended minimum speed for Design
Envelope pumps is 580 rpm. Running for long periods
below this speed can damage the mechanical seal.
6.0 programming, monitoring
and diagnostics
A key pad tool (lcp) is available for Design Envelope Pumps as
an option. The lcp gives the user full programming and monitor-
ing capabilities and it is recommended that at least one lcp and
cable kit are purchased for each installation site.
The lcp is connected via a cable to the ‘plug kit’ mounted in one
of the inverter cable entries as shown above.

6.1 lcp functions and operation
The functions of the control panel can be divided into
three groups:
• Display
•Keysforchangingprogramparameters
•Keysforlocaloperation
All data is indicated by means of a 4-line alphanumeric display,
which in normal operation is able show 4measurements and 3
operating conditions continuously. During programming, all the
information required for quick, eective parameter Setup of the
Design Envelope Pump will be displayed. As a supplement to the
display, there are three leds for voltage, warning and alarm.
All program parameters of the Design Envelope Pump can be
changed immediately from the control panel, unless this
function has been blocked via parameter 018.
6.1.1 display
The lcd-display has rear lighting and a total of 4alpha -
numeric lines together with a box that shows the direction of
rotation (arrow) and the chosen Setup as well as the Setup in
which programming is taking place if that is the case.
1st line shows up to 3measurements continuously in normal
operating status or a text which explains the 2nd line.
2nd line shows a measurement with related unit continuously,
regardless of status (except in the case of alarm/warning).
3rd line is normally blank and is used in the menu mode to show
the selected parameter number or parameter group number
and name.
4th line is used in operating status for showing a status text or
in data change mode for showing the value of the selected
parameter.
An arrow indicates the direction of rotation of the pump
(factory set). Furthermore, the Setup which has been
selected as the Active Setup in parameter 004 is shown.
When programming another Setup than the Active
Setup, the number of the Setup which is being programmed will
appear to the right. This second Setup number will flash.
6.1.2 led's
At the bottom of the control panel is a red alarm led and a
yellow warning led, as well as a green voltage led.
If certain threshold values are exceeded, the alarm and/or
warning lamp lights up together with a status and alarm text on
the control panel. The voltage led is activated when the Design
Envelope Pump receives voltage; at the same time the rear
lighting of the display will be on.
6.1.3 control keys
The control keys are divided into functions. This means that
the keys between display and indicator leds are used for
parameter Setup, including choice of display indication during
normal operation.

Operating variables 1,1 and 1,2 and 1,3 in the first line, and operat-
ing variable 2in the second line are selected via parameter 009,
010, 011 and 012.
Read-out state I:
This read-out state is standard after starting up or after
initialisation.
Line 2gives the data value of an operating variable with related
unit, and line 1provides a text which explains line 2, cf. table.
In the example, Frequency has been selected as variable via
parameter 009.
During normal operation another variable can immediately
be read out by using the [+/-] keys.
Read-out state II:
Switching between read -out states I and II is eected by
pressing the [display / status] key.
In this state, data values for four operating values are shown at
the same time, giving the related unit, cf. table. In the example,
Reference, Torque, Current and Frequency are selected as
variables in the first and second line.
Read-out state III:
This read-out state can be held as long as the [display / status]
key is pressed. When the key is released, the system switches
back to Read-out state II, unless the key is pressed for less than
approx. 1sec.
This is where parameter names and units for operating
variables in the first line are given - operating variable 2
remains unchanged .
6.1.5 quick menu
Quick menu gives access to a limited number of parameters
but does not include parameters that may need to be changed
when utilising sensorless control. It is therefore recommended
that parameter changes are made in the standard menu.
6.1.6 menu mode
The Menu mode makes it possible to select and change all
parameters at the user’s option.
However, some parameters will be missing, depending on the
