Leprecon LP-500 Series - Manual (Page 2)

THE LP 500 SERIES OPERATIONAL INSTRUCTION BOOKLET
The LP 500 series is a standard analog lighting controller. This 2 scene control board
can be broken into 6 basic sections.
The 500 series has a 6 channel chase, a bump system that can change the existing look
on stage momentarily, an output trim section, a master section, a dipless crossfade and
an individual channel adjustment section. The LP 500 series also has a 12 volt
dimmable gooseneck work lamp.
This controller uses a power source of 105-125 VAC 50-60 HZ and its output is a
continuous DC voltage across all channel.
POWER UP
When power is applied to this controller the dimmable gooseneck work lamp is
immediately accessible. This lamp is available in two different wattages, 2.4 and 5 watt.
The 2.4 watt bulb is standard equipment in all of our controllers. You can adjust the
intensity of the lamp by a clockwise rotation of the knob marked “lite”.
To engage or disengage the controller simply push the rocker switch marked “on”. The
green LED marked “power”, located beneath the switch, will be glowing.
If the LED is not glowing, recheck your power cord and be sure the outlet that you are
using is operational. If the outlet is operational and the power LED and work lamp are
not working, you may have an open fuse. The fuse is located inside the controller and is
mounted on the circuit board.
TRIM ADJUSTMENT
Under the “power” LED you will notice another green LED marked “max”. This LED’s
brightness is directly related to the amount of output. The factory trim adjustment is 10
volts, and is accessible from the recessed trim pot located next to the LED.
Under the “max” trim control is another recessed control for the minimum output voltage,
this is marked “min” and is factory adjusted to zero volts.
Do not readjust trim unless there is a reason for the adjustment, such as the
implementation of another brand of dimmer. Do this only with a volt meter connected to
the output of the controller. We will cover the procedure for trim adjustment later on in
more detail.
CHASER
The chaser has two sections. Section one has two control faders and a switch and is
located on the front panel next to the power section. Section two is a series of group
selector switches located on the rear of the controller.
The “M”, master fader controls only the “crossfader” section. The overall level that is set
by the “M” fader can be seen with the LED located directly above it.
