1. Channel output circuit breakers:
The circuit breakers are rated at 11.5 amps
continuous, however Jands recommend the maximum load connected to a channel be
limited to 10A. If nuisance tripping occurs, enable the Preheat option (see section
4.1.4.5). See also section 5.6 for a full explanation of nuisance tripping.
2. Display:
A red four digit alpha-numeric display is used to show dimmer status and
option menus.
3. LEVEL/FUNCTION encoder wheel:
This detent action control knob is used to
select items from the menus, and to select the channel levels or chase rate (depending
on the operating mode).
4. DMX IN/LOOP connectors (Rack-mount only):
A standard five pin AXR
connector inputs control desk DMX-512 signals and a second “Loop” connector
outputs them to other dimmers. See section 8.2 for wiring details.
5. DMX IN LED:
A green LED indicates the presence of DMX signals.
6. Keypad:
These switches are used to select different options and operating modes.
A red LED is associated with each switch to indicate activation of selected function.
7. PHASE LEDs:
Three green LEDs (one for each phase) indicate that the three
mains supply phases are available.
8. Channel SELECT switch:
These select or deselect options for each channel, or
switch a channel between “on-line” and “off-line”. If a channel is “off-line”, it will not
respond to the DMX input signals.
9. Channel STATUS LED:
A bi-colour LED indicates channel status, ie.
Red
=
channel set for 60 or 120V output
Green
=
channel set for 240V output
Off
=
channel disabled
Orange
=
voltage change selected but not yet confirmed
Flashing
=
channel selected for changes to be made
10. DRIVE LED:
This green LED indicates a control signal is being applied to that
channel.
