development.
WARNINGS AND PRECAUTIONS
Equipment, probe failure, blown fuses and/or
tripped breakers may prove harmful to the
contents of the building. Therefore it is strongly
recommended to install backup devices and alarm
or warning devices. Spare equipment should also
be available at the owner’s site. Equipment
manufactured by the manufacturer is protected
against normal line surges. High surges caused
by thunder storms or power supply equipment
may damage this equipment. For added security
against line voltage surges it is recommended that
surge and noise suppression devices be installed
at the electrical distribution panel. Use of shielded
cable for probes is recommended for protection
against lightning. These devices are available
from most electrical supply distributors.
RECOMMENDATIONS
The manufacturer recommends that all installation
procedures described herein be performed by a
qualified electrician or installation technician.
Further more the manufacturer recommends to
test all the functions and equipment connected to
the VPM, including the alarm system and backup
devices, after installation, after changes to the
installation and every month after that.
Fuse verification and replacement, as well as the
proper setting of control values shall be the
responsibility of the owner of this equipment.

1.1 DESCRIPTION
The VPM-1 is designed to drive one variable speed fan
of up to 6 amp per stage, under the master control ( LX
or IC) system resulting in a clean air environment for
your livestock.
The VPM-1 provides you with automated control over
its one stage via the use of the master control.

contact your local distributor for return material
procedures.
The package should contain the following standard
items:
•1 VPM-1 control
•1 cable fastener or fuse
•1 user’s manual
2.2 MOUNTING
Mount the unit to the wall using the mounting holes
located on the flange of the control housing.
Once the VPM-1 is in place, use a screwdriver to
remove the four screws holding the faceplate to the
housing.
To limit the unit’s exposure to noxious gases install
To limit the VPM-1’s exposure to noxious gases,
install the unit in a hallway.
Make sure the VPM-1 is properly installed, that is,
side up with the cable entry holes facing down. DO
NOT DRILL ADDITONNAL HOLES INTO THE
ENCLOSURE.
The VPM-1 operates in a temperature range of 0°C
(32°F) to 50°C (122°F).
The enclosure is watertight, but not splash proof or
immersion proof. DO NOT CLEAN WITH HIGH
PRESSURED WATER. Cover it carefully with plastic
when cleaning the room.
Install in an area protected from sunlight.
It is prohibited to use overhead cables outside the

installation of cabling to the unit. Knock-outs may be
difficult to remove, drill out if possible.
It is strongly recommended to install PVC conduits.
Make sure that the cables are water tight.
2.3.2 - Connecting 115VAC Fans
Refer to figure 1.
•Connect L1 of the power source to terminal 1 for fan 1.
•Connect the ground wire of the power source to the
ground wire in the housing of the unit.
•Connect the neutral side of the power source to the
neutral of fan 1.
•Connect the live lead of fan 1 to terminal 2.
2.3.3 - Connecting 230VAC Fans
Refer to figure 2.
•Connect L1 of the power source to terminal 1 for fan 1.
•Connect the ground wire of the power source to the
ground wire in the housing of the unit.
•Connect L2 of the power source to the appropriate
terminals of fan 1.
•Connect the appropriate lead of fan 1 to terminal 2.
Do not apply power to the control panel until all con-
nections have been completed!
Maximum load of 10 amps per stage only.

2.3.4 - Connecting to the master control
•Install a 18 - 22 AWG cable pair between the VPM-
1 and the LX control. The maximum cable length is
of 500 feet (150m).
•Connect one end of the cable to the (+) and (-)
terminals of the VPM-1 low voltage terminal block.
Refer to the bottom left corner of figures 1 or 2.
•All wires between the master control and the VPM-
1, as well as the probes should be shielded.
•Do not place low voltage cable into power conduit.
2.4 POWERING UP
Before powering up the VPM-1,
•Screw the faceplate to the casing of the unit using
the four screws previously removed.
•Verify the fan’s motor specifications. The current
must not exceed 10 A per stage
•To test the unit use the manual override parameter
indicated on the master control.
•When you have completed verifying the fan
operation, set the manual override parameter on
the master control to AUTO.
When using 3 phase power, ensure that the
phase supplying the master control and variable
fan is the same. Otherwise the control signal of
the master control will be too early or too late and
the fan will not rotate as expected.
