XXX XXX
Same as above except the “A” and “B” is replaced with “ ” to indicate if one or both of the DMX
inputs are terminated. For example, if the system is receiving 48 channels on DMX-A and 512
channels on DMX-B, with only DMX-A terminated, the display will show “ 048B512”. Refer to
menu items “DMXA-TRM” and “DMXB-TERM” on page 12 for further details.
SH XX:YY
Displayed when DMX is disconnected and the systems predetermined DMX status hold (SH) time
is counting down. “XX” represents minutes while “YY” represents seconds. Refer to menu item
“SH TIME” on page 15 for further details.
INF HOLD
Displayed when DMX is disconnected and the systems predetermined DMX status hold (SH) time
is set for infinite (INF) hold. Refer to menu item “SH TIME” on page 15 for further details.
SCENE:XX
Displays the scene (1 to 12 or 24) that is currently activated. Refer to menu item “L-BUTTON”
on page 17 for further details.
REM-TEMP
Displayed when the remote over-temp sensor is triggered via the OEM thermostat, mounted on
the heat-sink inside the CD80 dimmer pack. The thermostat closes when an over-temperature
condition of 180°F ±7°F (82°C ±4°C) is reached. All dimmer outputs are disabled and the fan is
turned on to full until the thermostat temperature drops to within specification.
CTL-TEMP
Displayed when the microcontroller senses an internal over-temperature condition of 185°F (85°C)
or more. All dimmer outputs are disabled and the fans are turned on to full until the temperature
cools down to 178°F (81°C) or less. Refer to menu item “CTL TEMP” on page 18 to view the
current microcontroller temperature.
Ø ERROR!
Displayed when an error is sensed on any of the input power phases. A phase error can be caused
from an under-voltage of less than 100VAC for 120VAC operation and 200VAC for 240VAC
operation, an over-voltage of greater than 130VAC for 120VAC operation and 260VAC for 240VAC
operation, or if a zero-cross phase reference is not detected.
FAN ERR!
Displayed when a blown (open) fan fuse is sensed. A blown (open) fuse suggests the fan may be
defective and needs to be replaced (Johnson System Inc., Part Number: CF-CD80P). Replace the
fuse (located on the DPC-24/12 circuit board) with a 2A, 250V, fast-acting, GMA type fuse only!
RTC ERR!
Displayed when the system detects a runtime counter (RTC) error. This occurs when there
is an invalid hard-key code and the runtime counter is greater than 2160 hours (90 days).
Refer to menu item “HARD-KEY” on page 18 for further details.
LOCKED!!
When the DPC-12 or DPC-24 is powered up, the menus are “LOCKED!!” with access only to
the basic system configuration menus, which includes setting the DMX start address as well as
enabling or disabling the end-of-line DMX termination. The menus need to be “UNLOCKED”
to access the advanced system configuration menus. To toggle between “LOCKED!!” and
“UNLOCKED” press and hold down the EXECUTE and then ESCAPE switches at the same time
for 4-5 seconds.
