1. GENERAL
This document provides you the necessary information
to install and operate the SVIM-1LE. The document is
presented as follows:
•Introduction
•Installation
•User’s Guide
•Appendix
1.1 DESCRIPTION
The SVIM-1LE is a positioner which controls motorized air
inlets. The SVIM-1LE is connected to a master control
either a SVC or an IC (configurable control). With the
commands sent by the SVC or IC, the SVIM-1LE is able to
position an air inlet according to the ventilation requested.
The SVIM-1LE can control two different types of air inlet
actuators: with or without feedback potentiometer.
•With feedback potentiometer: The positioning is
controlled by the feedback potentiometer which
delivers a more precise positioning.
•Curtain time positioning (time mode): This method
is used when the air inlet system does not have a
feedback potentiometer. The time mode positioning
uses the the travelling time of the curtain to
evaluate its position.
Calibration
The SVIM-1LE has a calibration function very simple to
use. The calibration allows the unit to establish its own
position references during installation.
User’s Settings
The SVIM-1LE is easy to use; most settings are
automatically set by the master control (SVC or IC).
However, the user can also adjust some settings, in
order to adapt the SVIM-1LE functioning to particular
needs of an application. With the 4 digit LED display,
the SVIM-1LE keeps you informed of its status, it also
CHAPTER 1 - INSTALLATION

Page 6
SVIM-1LE
allows to be aware of the system general status and
error messages, if it happens.
Security
The SVIM-1LE has several security features. In case it
loses communication with the master control, the SVIM-
1LE is able to operate autonomously the air inlet by
using his own temperature probe or by positioning itself
to a preprogrammed position.
The SVIM-1LE is also able to detect problems
associated with irregular feedback from a problematic
potentiometer. If it happens the SVIM-1LE switches to
time mode, thus allowing normal operation until the
problem is solved.
The time mode feature offers a curtain re-positioning
function. This feature will ensure dependable long term
actuator precision even in the absence of a feedback
potentiometer.
Temperature Probe
The SVIM-1LE temperature probe can be installed in
two different ways:
•Inside probe: With inside temperature probe the
SVIM-1LE is able to command the air inlet,
according to the room temperature, in case the
master control loses power or fails.
•When using an IC (intelligent control) in conjunction
with the SVIM always use the inside probe
configuration (use only the Inside probe option).
•Outside probe: For applications without feedback
potentiometer, the outside probe is used to ensure
that the air inlet re-positioning will not be done if the
outside temperature exceed a certain temperature
limit.

2.2 INSTALLATION
•Use a screwdriver to remove the faceplate and the
power compartment’s cover.
•Once both faceplates are off, install the mounting
screw on the wall and install the unit on it.
•Secure the SVIM-1LE in place using the bottom
mounting holes.
To limit the unit’s exposure to noxious gases install it
in a hallway.
Make sure the unit is properly installed, that is, side
up with the cable entry holes facing down.
The SVIM-1LE will operate in a temperature range of
32°F to 120°F (0°C to 50°C).
The enclosure is watertight, it is not splash-proof or
immersion-proof. DO NOT USE PRESSURIZED
WATER on the control. Cover it carefully with plastic
before cleaning the room. Also, DO NOT drill
additional holes in the enclosure.

2.3 CONNECTION PROCEDURE
2.3.1 Cabling
Use a screwdriver to remove cable knock-outs for the
installation of cabling to the control panel.
2.3.2 Connecting a Unit
Refer to figure 2 for standard actuators, to figure 3 for
actuators using a Hired Hand switch box (PVR-2) or to
figure 4 for a 3 phase actuator.
A temperature probe can be outside the building (see
sections 2.4.2 and 3.2.3.6).
Do not apply power to the control panel until all
connections have been completed. The current draw
of the load should be in the range of 100mA to 5A
when it is activated. Set the voltage switch inside the
SVIM-1 to the correct value before power up.
Note: It is recommended to use the actuator on the
longest travel time possible to obtain maximum
accuracy in the curtain’s positioning.
Some actuators have a maximum functioning time.
The calibration must be done within the maximum
time, in order to avoid overheating motors. (Also see
3.2.3.12, page26)
The maximum actuator travel time (opening or
closing) must not exceed 45 minutes.

2.3.3 Connecting to the Master Control
•Install a #22 AWG shielded cable between the
SVIM-1LE and the master control. The cable can
extend to a maximum length of 750 ft (230M).
•Connect one end of the cable to the (+) and (-)
terminals of the SVIM-1LE low voltage terminal
block. Refer to figures 1 (6) and 2.
2.3.4 Connecting to a Feedback Potentiometer
If a feedback potentiometer is used:
•Connect the two potentiometer wires to the
SVIM-1LE two terminals indicated as POT on the
left hand terminal. Refer to figures 1 (6) and 2.
•Connect the common potentiometer wire to the
terminal GNA.
•Connect the other wire to the terminal POT.
CAUTION: It is recommended to use an air inlet system
where the motor is able to work without overheating.
Remember that a bad connection of the cables / pulley
between the actuator and the curtain influences the
accuracy of the curtain’s positioning.
Note: The potentiometer’s resistance value must
increase when the air inlet opens.
ACTUATOR CONNECTION
Note : the wire connecting the SVIM-1/24LE and the
actuator can not be longer than 200 ft (60M) and must
have a minimum capacity of AWG # 16. It is also
recommended to select the better wire depending on
the installation. For example, when the distance is too
long or the actuator has a strong current, you need to
use a bigger conductor, in order to avoid voltage
drops.

2.4 SWITCH SETTINGS
2.4.1 Line Voltage Selector Switch Refer to Figure 1 (4).
This switch is located on the surface of the main
(bottom) board and adapts the control panel for
115VAC or 230 VAC line voltage.
2.4.2 Software Setting DIP Switches Refer to Figure 1 (7)
These switches are located on the bottom main board and
adjust the following options:
Switch 1: Set to ON if a feedback potentiometer is used.
Switch 2: Channel selector: When 2 SVIMs must be used on
the same configurable control port (with the
appropriate configurations), each #2 dipswitch
must be set at different positions.
Switch 3: Determines the SVIM-1LE’s temperature probe
location.
Inside probe: The SVIM-1LE is able to control the
curtains or shutters positioning according to the
inside temperature in normal or in backup mode.
Outside probe:Allows to delay the auto-calibration
cycle if the outside temperature exceeds the limit set
in parameter CLd.t. or Hot.t. This parameter only
appears when time mode is selected (no feedback
potentiometer).
Switch 4:Selects the appropriate operating parameters
according to the master control (SVC or IC).

2.5 POWERING UP AND CALIBRATION
Before powering up the SVIM-1LE, attach the faceplates
to the casing of the control panel using the screws
previously removed.
The SVIM-1LE has to be calibrated the first time it is
started. This calibration enables the SVIM-1LE to
evaluate the maximum and minimum positions of the
curtain / inlet. Two-step initial calibration:
Step 1: Press the SETUP button until CAL flashes on
the display.
Step 2: Press the and buttons simultaneously.
At this point, the Calibration LED turns on and the
calibration process, consisting in the 8 following
operations, begins:
1 Inlet closes completely to set minimum position
2 Inlet opens completely to set maximum position
3 Cooling delay PAUS (if activated)
4 Inlet closes once again
5 Cooling delay PAUS (if activated)
6 Inlet opens in steps
7 Cooling delay PAUS (if activated)
8 Inlet closes in steps
Once the process is successfully completed, the
SVIM-1LE is ready for normal operation. It is possible to
interrupt the calibration cycle by repeating steps 1 & 2.
To test the unit independently from the master control,
set the SVIM-1LE to MANUAL mode ( see section 3.2.2
in the user’s guide). Then press the adjustment buttons
to open or close the air inlet. If the air inlet does not
move or an error message appears, refer to the
Troubleshooting section in the appendix of this
document.
