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 10 amps. The HP6-C breakers are rated at 25 amps but Jands recommend the
maximum channel load be limited to 20 amps. 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: A standard five pin AXR connector inputs control
desk DMX-512 signals and outputs them to other dimmers via the Loop connector. 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 phase
mains supply is 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 110V 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.
