IES PowerModule Operators’ Manual v1.4 Isine 4
CHAS (with LED)
CHASe. Provides access to the dimmer’s internal
20-pattern chase effects system for stand-alone
display effects. The LED illuminates when the
dimmer is in the ‘chase’ operation mode.
CONF
CONFigure. Access to a sub-menu to set the
detailed configuration for individual or combined
dimmer channels. Options available are:
MAX MAXimum. Sets the
maximum output level from
30% to 100%, individually or
combined.
MIN MINimum. Sets the minimum
output level from 0% to
29.9%, individually or
combined.
T-IN Response time to fade in from
0.00 secs to 99.9 secs.
T-OUT Response time to fade out
from 0.00 secs to 99.9 secs.
CURVE Dimmer law selection
NONDIM I/O. On/off operation
PRIORITY Priority channel (the last to be
reduced if the maximum
preset current is exceeded by
the module).
MODE Start mode (normal, soft start,
burst, proportional, blink)
MAN
MANual. Provides manual control of each channel
for circuit testing and pre-setting.
EXIT
Returns to the opening screen menu option without
recording changes.
INFO
INFOrmation. Provides a display of the nominal
supply voltage, current and frequency. After 3 secs.
also gives details of the installed software versions.
CHK (with LED)
ChecK. Displays a log of any circuit or dimmer
faults. LED illuminates if an error occurs.
4 Function overview
4.2 Maximum and minimum levels
The maximum output of the dimmer may be
adjusted to improve lamp life or to limit the power
used. A minimum level (preheat) may be necessary
with some filaments to improve the speed of fast
flashes or chases. An option exists to switch off the
preheat when the DMX signal is not present (i.e.
when the control desk is switched off).
4.3 Response speed
The time taken for a dimmer to ‘fade’ to the applied
control signal level is used to control the rate of
change of current to the filament improve lamp life
for higher wattage filaments.
4.4 Non-dim operation
Each dimmer may be selected to operate as a
dimmer, or as a non-dim switch.
4.5 Local control
PowerModules have a range of integrated control
facilities for basic operation without a control desk.
These include live manual control of each dimmer
level, preset recorded levels for fixed display
lighting, and access to an in-built chaser which
provides 20 chase patterns.
4.6 Dimmer curves
A selection of dimmer curve transfer functions (the
relationship between from control signal level and
dimmer output) are available to compensate for the
different visual responses of a live audience or a TV
camera, and to provide improved dimming for non-
resistive loads such as fluorescent tubes.
4.7 Status reporting
All IES dimmers incorporate a bi-directional
communications system called DimSTAT which
provides feedback of the dimmer status and fault
reporting to a PC. DimSTAT also enables a remote
PC to control any dimmer in the network, and to
update the dimmer’s internal operating software and
preset options.
4.8 Backup settings
Should the DMX signal fail, the PowerModule can be
programmed to hold the present level, fade to zero
or fade to a pre-programmed backup level.
