Plant Check?
While on the main running screen press the UP and the DOWN arrow
keys simultaneously to put the unit into PLANT CHECK MODE. This
will cause the controller to ramp slowly up to full speed and stay
there. To cancel this mode either turn the power o or hold the up
and down arrow keys simultaneously again.

Installing
Mounng
The 11, 15 and 22Kw drives share the same dimensions:
The controller must be mounted vercally with sucient clearance above and below the drive to allow air to circulate freely.
The operang temperature range is –10 °C to 40°C.
Mount the transducer in the vacuum line as near as is praccal to the claws.
The transducer should be mounted vercally at least 1M from any bends , air
bleeds or regulators.
Try to avoid placing the transducer close to any heat sources, in parcular it
should not be mounted within 1 meter of a steel roof.

Wiring
All wiring must be performed by a suitably qualified person who is familiar with, and ensures compliance
with, the appropriate Electrical Wiring Regulations.
There is no need to use screened mains cabling.
EMC screened cable must be used to connect the controller and motor. An EMC gland must be fitted to
the motor and the preinstalled EMC Gland must be used in the controller.
All wiring that exits the controller including low voltage control cabling must be screened.
The picture above shows the control terminals of the VPC. The terminals are numbered from 1 to 28 and
their funcons are shown on page 8. The wiring and links shown in the picture are installed by Sema and
are necessary for the correct funconing of the controller. Please do not remove or alter any of these.
While there are other oponal components
which may be wired to these terminals (see
page 8) the only addional piece of wiring
which is essenal to make the unit operate is
from the transducer. Connect this as follows:
RED wire to terminal 1.
BLACK (in some cables this may be blue) wire
to terminal 6.
Green/Yellow striped (in some cables this may
have a clear covering) wire to terminal 7 or 9

Three Glands are ed to the boom of the VSD.
25mm Gland
for the Main
supply cable
32mm Gland with
a brushed locknut
ed. This is
meant for the
motor cable
20mm Gland for the
Transducer cable and
the controller commu-
nicaon cable
The motor gland has a brushed locknut ed to it (see below). Somemes well intenoned installers remove this gland and
locknut and replace it with an EMC gland. Please note that the brushed locknut has an equal or greater performance to an
EMC gland and that there is nothing to be gained by replacing it. To terminate the screen of the motor cable to the brushed
locknut simply strip back enough of the plasc sheath so that the screen can contact the brush before inserng the cable
through the gland. This will make an extremely eecve EMC earthing connecon and also maintain the units waterproong
rang through the use of an IP68 gland.

Power and Motor Connecons
To reverse the direcon of rotaon of the motor change over any two of the three motor
wires (U,V and W)
Ensure that the motor is connected in either Star or Delta as is appropriate to the voltage of the controller.
Typically a single phase 230Vac controller will require the motor to be connected in Delta and a three phase 400Vac controller
will require that the motor is connected in Star. There are excepons to this with some motors supplied from overseas so
please check the motors nameplate.
Connect the main
supply wires to
L1, L2 and L3
Connect the mo-
tor wires to U, V
and W
Connect the
earth wires to
the earth screws
Recommended Pracce
To lessen the risk of the unit being damaged by lightning strikes when it is not in use Sema
recommends that the power be turned o at the compleon of milking.

Seng up and Operaon
Using the keypad
Descripon:
ESC The escape key funcons in the same manner as the escape key on a computer it allows you to exit without sav-
ing parameters and also allows you to go back a step when going through the inial setup roune.
UP ARROW Increases the digit immediately above the cursor when entering parameter values and scrolls
through a menu list.
ENTER Accepts and saves a value which has been entered. Press and hold for 3 seconds to access the Funcon
menu from the main running screen.
MAN Short for Manual. This toggles between Milk and (oponally Herd Test mode and) Wash modes. In wash
mode the vacuum pump runs at full speed. Use this mode for plant checks.
LEFT ARROW Moves the cursor one posion to the le when entering parameter values.
DOWN ARROW Decreases the digit immediately above the cursor when entering parameter values and scrolls
through a menu list.
RIGHT ARROW Moves the cursor one posion to the Right when entering parameter values.
ON OFF Press once to turn the controller o, press again to turn the controller on. The controller will remember
the state of this buon between power ups.
Hint: When entering numbers use the le and right arrow keys to move the cursor and the up and down arrow keys to
change the number above the cursor.

Inial Set Up
A few seconds aer powering the unit up for the rst me, or aer re-inialising it, the screen below will be displayed.
The only valid key which can be pressed is the ENTER key and the only way of stopping this screen from appearing is to com-
plete the setup roune.
Please note that, if you make a mistake and enter the wrong value in one of the steps, the ESC key can be used to go back a
step. You can go back as many steps as you like even right to the start of the setup roune if necessary.
The sengs that you enter are only saved aer you complete the last step so, providing you haven’t completed the nal step,
you can always start setup again by turning o the power and then powering up again.
The controller can also be re-inialised. See the ’Changing Parameters’ secon for instrucons on how to do this.
There are 21 steps in the setup roune and they are as follows:-
1. SELECT THE TYPE OF SHED: use the up and down arrows to cycle through the available opons, press the
ENTER key to accept.
2. ENTER THE NUMBER OF SETS OF CLAWS: Use the arrow keys to alter the value. Hint: When enter-
ing numbers use the le and right arrow keys to move the cursor and the up and down arrow keys to change the number
above the cursor.
3. SELECT THE TYPE OF PUMP: use the up and down arrows to cycle through the available opons, press the
ENTER key to accept.
4. SELECT THE TYPE OF TRANSDUCER: The default seng of “Sema Type 1” will almost always be correct
but the unit can also use other types of transducer including the Delaval/John Brooks transducer. Contact Sema for advice if
you are using something other than a Sema type 1 transducer.
5. ENTER THE MOTORS NAMEPLATE VOLTAGE: Use the arrow keys to alter the value.
6. ENTER THE MOTORS NAMEPLATE CURRENT: Use the arrow keys to alter the value.
7. ENTER THE MOTORS NAMEPLATE RPM: Use the arrow keys to alter the value. (Hint: If this is a belt
