For commissioning connect the PTC-thermistor’s
from the main terminal box of the main motor onto
terminals 1X1:27/28
For your convenience the implemented insulation
amplifier transform all incoming reference values into
a suitable current signal for the control board (11U1).
To adjust the insulation amplifier turn the screw into
the right position (see wiring diagram, page 12).
The motor-starter (13Q1) includes a thermal and
over-current protection to protect the external fan
cooling only. The motor has to be connected onto
terminals 1X1:29/30/31. It is necessary for
commissioning to switch on the starter otherwise the
VFD occur an external fault and it isn’t possible to
start the drive !
The transformer (10T1) is implemented to provide
230V~, 50Hz suitable for customer
connection’s.
•
What to do when the filter-fan’s don’t run ?
Check the Neozed fuses (10F1)
Check the Fuse C-Characteristic (10F2)
Check the power supply to the VFD cabinet
•
Are reference values preset by the factory ?
No, only if we had detailed data from client.
•
What’s wrong when the VFD tripped and it isn’t
possible to restart ?
Please check refer to point 1 and measure
resistance value of PTC
Check parameter for RO1 “RUN”
3.4 Performance and operating limits
In the interest of operator safety
the unit must not be operated above the nameplate
conditions. Such operation could result in unit failure
causing injury to operating personnel. Consult
instruction book for correct operation and
maintenance of the pump and its supporting
components.
4.0 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulations, see section 1.6.4, Products used in
potentially explosive atmospheres.
4.1 Location
The pump should be located to allow room for
access, ventilation, maintenance and inspection with
ample headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped.
Refer to the general arrangement drawing for the
pump set.
4.2 Part Assemblies
The pumps are delivered completely mounted and
prealigned with the motor. Also the shaft seal is in the
correct position. If drivers and/or seal systems are
delivered separately, follow the assembly procedure in
section 6.8.
4.3 Foundation
The foundation shall be located on a place that allows
a minimum of pipe work and that is easily accessible
for inspection during operation. According to the
environment the foundation may consist of concrete
or of steel. It must be rigid and heavy enough to
absorb normal vibrations and shocks.
4.3.1 Horizontal alignment of the baseplate
Horizontal alignment is done with leveling screws.
Use a spirit level for correct horizontal alignment of
the baseplate.
The max. misalignment is 0.5 mm/m
baseplate length.
4.3.2 Steel foundation
When the pump unit is mounted directly on structural
steel frame, it shall be well supported by constructural
beams. It is recommended to check the natural
frequency of the steel frame, because it shall not
coincide with the pump speed. The exact horizontal
alignment is very important!
4.3.3 Concrete foundation
A concrete foundation must have an exact horizontal
alignment and must be placed on solid ground. First a
basic foundation shall be built with square shaped
holes for embedding the foundation bolts. After
putting the base plate into the foundation the proper
alignment can be obtained by adjusting it with shims
under the base plate. Now insert the foundation bolts
and grout the space between the basic foundation
and the base plate with grouting cement (refer to
illustration)
It is very helpful to use a properly made and stable
wooden frame around the base plate. So the grouting
cement will not flow side. When the grouting is totally
set and hardened the foundation bolts shall be
tightened in a firm and symmetrical way.
