Installation Instructions

Viper 2000 Control System

PRD0167E01en

Introduction

• This instruction sheet only deals with control unit Viper

2000.

• Remove all packaging and check that the goods supplied
are not damaged.

• Check that the articles supplied correspond with those
specified on the delivery note.

Read through the documentation attached to the prod­uct before starting installation work.

Placement of the control units

The control units are to be placed at a place where it is protect­ed from water. The nodes should be placed in the distribution
box. The display unit is to be places in a way that the driver
doesn’t have to move, and preferably in a way that a minimum
of sunlight is reflected in the display.
To mount the sensors, see separate installation sheet
PRD0070.

Ensure that the control units are placed at a place pro­tected from water.

Footnotes

1. If the flap motor drive has an additional position

feedback, the flaps can be positioned in a
selectable number of intermediate positions. If left
unconnected the flaps will go all the way to their
respective mechanical stop positions.

2. This option is added for the case that analog

positioning of valve control motors is required. If a
single solenoid is to be used - connect the coil
between ground and either the inverted or non­inverted output.

3. These outputs are added in order to make it

possible to use only the control unit as a
compartment controller.

4. The feedback potentiometers can be connected
directly between GND and +24V. Variations of
supply voltage are internally compensated.

4. The feedback potentiometers can be connected
directly between GND and +24V. Variations of
supply voltage is internally compensated.

5. Direct drive capability is a hardware option that
can be delivered on request. Since no single input
pin can carry a load of more than 10A, additional
Batt+ connections has to be done.

6. If no high current drivers are used, only one of
these outputs need to be used. If only one high
curren driver is used, two of these has to be
connected and if two or more are used all three
supply pins should be connected.
