OUTPUT CHANNEL CONNECTIONS
The RE-82 is supplied with one of several rear panel output options. Channel output connections are according
to the the rear panel selected. Channel connections generally proceed from left to right (if you are facing the rear
of the unit). Channel “A” will be on the left end. Connections for load Neutrals are provided. There is also a
ground lug terminal to be used for your load circuits grounds.
OPERATION
CHANNEL ASSIGNMENT
The starting channel of each RE-82 is selected using the DIP switches on the front panel. The diagram below
indicates the actual value of each DIP switch position. A chart at the end of this manual "CHANNEL
ASSIGNMENT SWITCH SETTINGS" provides further information for setting the starting address DIP switches.
Any switch in the up position ADDS the associated value to the starting channel number. All switches down =
starting channel number 1.
For example: to set the starting channel to 13, move the 2nd switch from the right (value 8) and the 1st switch
from the right (value 4) to the up position. For a starting channel of 21, move the third switch from the right (value
16) and the rightmost switch (value 4) to the up position.
MANUAL CONTROL
Dimmer channels can be activated manually by pressing corresponding button switches located on the front
panel. This will latch the associated channel to full on. Push the button again to turn the channel off. The
associated LED will light when the channel is activated.
NORMAL OPERATION
LEDs located on the front panel of the RE-82 indicate channel levels as you operate faders on your console. The
"VALID SIGNAL" LED will light whenever the dimmer is receiving a control signal within the range of channels
that the dimmer is assigned to. The "Phase A" and "Phase B" LEDs will indicate that power sources are applied to
the dimmer. The fan will run continuously whenever power is applied to the RE-82. An over-temperature sensor
will shut down all channel output if the dimmer temperature rises above safe limits (
≈175°F exit air temperature).
RELAY MODE
The two leftmost switches control the "relay" mode. When either switch is in the up position, the channels
associated with that switch operate in non-dim mode. These channels will be either full on or full off depending on
the level of the faders controlling them.
