8. FRONT PANEL LED'S (Front Panel, Figure 7, Page 10)
SIGNAL INDICATOR (Green)
This LED senses the presence of a digital signal from the lighting console. If a digital signal is correctly applied,
the LED will glow solid green. If signal is not present or incorrectly applied, the LED will either not turn on or will
flicker.
AIRFLOW INDICATOR (Amber)
This LED when on indicates the lack of airflow over the dimmer modules. The Airflow indicator will turn on and
shut down all dimmer outputs within the pack for several reasons, such as: a fan failure, missing dimmer
modules, or an obstruction in the airflow. To reset a module in Airflow mode, remove any obstruction or replace
any missing modules, and the control module will automatically reset itself. In the event that these actions do not
restore the system, you may need to have the fan circuitry repaired. A failure in any one Pack will light its LED,
but not the LED in any other Pack.
POWER INDICATOR (Red)
The Power Indicator will blink if any phase is missing or incorrectly wired. The Power Indicator will glow steadily if
all wiring and phasing is correct.
9. ANALOG INPUT CONNECTOR (Front Panel, Figure 7, Page 10)
Connecting your analog control input into the 15 pin "D" connector on the front panel will allow control from a non-
multiplexed analog console to drive dimmers. If both analog and a multiplexed protocol are used at the same time, the
analog levels will pile-on to the multiplexed levels. Cables must be terminated on the pack end with a Cannon DA-15P or
equivalent "D" connector.
10. ANALOG INPUT TRIM ADJUSTMENT SCREW (Front Panel, Figure 7, Page 10)
Your non-multiplexed analog input voltage can be adjusted using the trim adjustment screw on the front panel. The
control module is factory set for 0 to 10V but can be adjusted to accept 0 to 4.5, 0 to 15, or any voltage in between those
values using the trim adjustment screw. Table 6 is a listing of connector pin numbers and their functions in the control
module.
The Control Module will respond to a filtered full wave DC linear voltage or to a linear transition of a pulse-width
modulated DC voltage within the frequency range of 900 Hz to 11 kHz. The input impedance of each dimmer is 21.3 kΩ.
