DESCRIPTION OF UNIT
The DB612 is a 6 channel dimmer with a capacity of
1,200 watts per channel giving a total of 7,200 watts.
The DB612 is controlled by the DMX512 lighting
control protocol. Individual channels may be set to
operate in "relay" mode where channels are
switched only on or off depending on console fader
position.
LOCATION AND ORIENTATION
THE UNIT SHOULD BE OPERATED
HORIZONTALLY WITH THE OPERATOR PANEL
FACING FORWARD OR BACKWARD (NOT UP OR
DOWN).
Make certain the ventilation holes on the face of the
unit are not obstructed. A six inch clearance should
be maintained between the unit and other surfaces
to ensure proper cooling. Do not place the DB612
where it will be exposed to moisture or excessive
heat. The DB612 is intended for
indoor use only
.
MOUNTING
The DB612 is designed to be mounted on truss
equipment using standard lighting pipe clamps. The
attaching bolt for these clamps will fit into an
inverted "T" slot located along the bottom of the
dimmer. The slot will also accommodate a 1/2" bolt
(3/4" across bolt head flats). Use a pipe clamp to
mount the DB612 above a truss bar.
MOUNTING ADAPTERS
The DB612 is supplied with three mounting adapters
and their associated hardware. The primary purpose
of the adapters is to provide a way to install the unit
below a truss bar without turning it upside down.
The adapters can also be used for other user
defined mounting arrangements.
TO INSTALL THE MOUNTING ADAPTERS
1.
Install a pipe clamp on the end of the
adapter which overlaps itself. Make the
clamp snug but not tight against the adapter
so you can make final adjustments when
installing the unit on a bar.
2.
Install 1/2" bolt and flat washer through the
other end of the adapter so the bolt head
and washer are inside the adapter.
3.
Slide the adapter (with the 1/2" bolt and flat
washer installed) on either end of the DB612
so the bolt head slides into the DB612 "T"
slot. The flat washer must be between the
DB612 and the adapter.
4.
Install a lock washer and nut on the 1/2"
bolt. Leave it loose enough to slide the
adapter along the "T" slot in the DB612.
5.
Slide the adapter along the DB612 "T" slot
to the desired position and tighten the nut
until it is snug. You may not want to
completely tighten the nuts so you can make
final adjustments when you hang the unit.
6.
Repeat the above process for the remaining
adapters.
7.
Hang the entire assembly on a truss bar by
the pipe clamps. Tighten down any
connections left loose during the previous
assembly process.
NOTE: Use of safety chains or cables is
recommended for any overhead dimmer
installation
