32. WARMING
Turn the “lamp warming” feature on or off.
The unique “lamp warming” feature is activated by a control level above 0% and lowers
the in-rush current to the dimmer (cold lamp filament) by up to 70%. This results in
significantly increased lamp filament life and lower long-term operating costs.
WARMING is set to ON by factory default, but may be turned OFF for some installation
applications. With WARMING set to ON, a maximum delay of 245 milliseconds is
introduced to “warm” the lamp when it is turned on. For fast chase effects the delay
may be undesirable, in which case, the “lamp warming” feature can be turned off.
Note that when standby mode is enabled the microcontroller goes to sleep within 5
seconds of inactivity on the control inputs, and there is delay of 150 milliseconds for
the microcontroller to wake up and restart normal run mode. To ensure virtually instant
dimmer control response, set STANDBY to DISABLED and WARMING to OFF.
Press EXECUTE to enter the menu and configure the lamp warming mode.
DISABLED
This menu is disabled to help prevent inadvertent changes. Proceed to enable.
ENABLED
Press and hold MENU (
) and MENU (
) at the same time for 4-5 seconds.
ON
Press EXECUTE to toggle the lamp warming mode from ON to OFF.
OFF
Press EXECUTE to toggle the lamp warming mode from OFF to ON.
Press ESCAPE or RESET to exit the menu.
Any change in the configuration is automatically saved.
33. POLARITY
Set the PWM output control polarity. Locked for factory use only!
This menu is only used when swapping the MADD-24 controller between different
Johnson Systems Inc. products and should never be accessed with DE90-3000 Series
retrofit control systems.
Press EXECUTE to enter the menu and configure the polarity mode.
DISABLED
This menu is for factory use, and is disabled for the end user.
ENABLED
Press and hold MENU ( ) and MENU ( ) at the same time for 4-5 second.
MODE:1
Press MENU (
) to select mode 1 - positive polarity for DE90-3000 Series.
MODE:2
Press MENU (
) to select to select mode 2 - not applicable for DE90-3000 Series.
MODE:3
Press MENU (
) to select to select mode 3 - not applicable for DE90-3000 Series.
MODE:4
Press MENU (
) to select to select mode 4 - not applicable for DE90-3000 Series.
The menu will automatically timeout after 2 minutes of inactivity and save.
34. LINE V
View the RMS line voltage for each power phase.
Press EXECUTE to enter the menu and view the line voltage of each phase.
ØA=120.0
Shows the line voltage of Phase A.
ØB=120.0
Press MENU (
) to view the line voltage of Phase B.
ØC=120.0
Press MENU (
) to view the line voltage of Phase C.
Press ESCAPE or RESET to exit the menu.
35. LINE F
View the line frequency of phase A.
60.0 Hz
Shows the frequency.
36. REM TEMP

The remote temperature sensor is not used in DE90-3000 Series retrofit control
systems.
+032°F
Shows the temperature in degrees Fahrenheit.
+000°C
Press EXECUTE to toggle units to degrees Celsius.
37. CTL TEMP
View the temperature of the microcontroller.
+91°F
Shows the temperature in degrees Fahrenheit.
+33°C
Press EXECUTE to toggle units to degrees Celsius.
