JUMPER SETTINGS
NON-VOLATILE MEMORY
The version C control card now contains an EEPROM device to store
lighting levels for automatic full restoration after a power fail.
When the installer enables this feature, the dimmer will save the
current lighting levels in non-volatile memory 10 minutes after there
has been a change in lighting levels. This is an important feature in
house and architectural lighting systems, where it is important for
the lighting to be fully restored after a power blackout. Dip Switch
8 may be left on in lieu of the memory jumper for restoration to a
fixed level of 50% instead.
In theatrical stage lighting systems, this feature may not be
desirable, since the dimming system is turned off frequently
SOFTSTART
The 2408 CD comes from the factory configured in the
“SOFTSTART” operating mode. This mode of operation forces at
least a 1/10th second delay between the output being full off to the
output being full on to allow a more gradual warming of the lamp
filaments. Thermal shock and inrush currents are reduced thereby
increasing lamp life and preventing nuisance tripping of the circuit
breakers.
To disable SOFTSTART; remove the jumper block from the pins
marked 112 on the firing cards. Each firing card affects only it’s
respective four channels. Replacing the jumper block will restore
SOFTSTART.
NOTE:
The 2408 CR and any channels of the 2408 CD configured for NON
DIM operation will not be affected by SOFTSTART.
