VISA LIGHTING LVPC-DIM Lighting Control Elevated Security Spaces
GENERAL INFORMATION
Note: i n this document “load” can refer to a single luminaire, a single circuit in a multi-function luminaire, or a group of two or more fixtures or luminaire circuits.
DO NOT CONNECT AC POWER TO ANY LVPC-DIM SWITCH INPUT OR DIMMING OUTPUT.
SEE LVPC-DIM USER GUIDE FOR MOUNTING REQUIREMENTS AND INPUT/OUTPUT RATINGS FOR CONNECTED LOADS AND CONTROL SWITCHES.
Independent Load Control with Dimming
The LVPC-DIM must be set to “MODE 4” in this configuration; see the LVPC-DIM
User Guide for more information. See the appropriate wiring diagram in these
instructions.
The LVPC-DIM can be used to control up to three loads independently. Up to two of the loads can be set up to “push-to-dim” where a short press of a control switch will turn the connected fixture on and off, and a long press will dim the fixture up or down. Loads must be 0-10V dimmable to use the push-to-dim function. These loads will be controlled by switches wired to the SWITCH 1 and SWITCH 2 control inputs on the LVPC-DIM. Fixtures connected to the third load output will have on/off control only via the SWITCH 3 control input.
Independent Load Control with Dimming and System Override
The LVPC-DIM must be set to “MODE 1” in this configuration; see the LVPC-DIM
User Guide for more information. See the appropriate wiring diagram in these
instructions.
The LVPC-DIM can also be used to control up to two loads independently, with
an additional system override capability. Up to two loads can be set up to
“push-to-dim” where a short press of a control switch will turn the connected
fixture on and off, and a long press will dim the fixture up or down. Loads
must be 0-10V dimmable to use the push-to-dim function. These loads will be
controlled by switches wired to the SWITCH 1 and SWITCH 2 control inputs on
the LVPC-DIM.
One or more additional switches can be connected to the SWITCH 3 control input to act as system override switches. A short press of an OVERRIDE switch will turn on all loads connected to the LVPC-DIM and force their output to 100%. All other load control switches will be deactivated until an OVERRIDE switch is pressed again.
Optional Switch Lock-Out Function (all configurations)
By adding a maintained on/off switch (typical rocker or toggle switch) to the
SW COM wiring, one or more load control switches can be locked out if/as
needed. When a maintained LOCK-OUT switch is ON the affected switches will
operate normally, but when the maintained switch is OFF the affected switches
will not affect the state of the connected loads. This functionality may be
useful if certain switches should be deactivated based on time of day or other
factors. It may be implemented with either control scheme detailed above and
on the following pages.

WARNING: When using electrical equipment, basic safety precautions should always be followed, including the following:
- Read all instructions carefully before installing and save for future use.
- Make sure all connections are by the National Electrical Code and local regulations.
- To avoid possible electric shock, be sure the power supply is turned off before servicing or installing the fixture
- Service should be performed by qualified personnel.
- These instructions may not cover all details or variations. If additional information is needed, please contact Visa Lighting.
