Fault description
Possible cause
Required measures
Humidity
(continued)
Icing at the evaporator plates.
Set-point was too long
below
ambient temperature.
Defrost the unit (chap. 18).
Condensation at the walls of the
inner chamber.
Combination of tempera-
ture/humidity values not in the
optimum range (see temperature
humidity diagram, Figure 20)
Select combination of tempera-
ture/humidity values in the opti-
mum range (chap. 17).
Set-point was too long below
ambient temperature, icing in the
preheating chamber.
Defrost the cabinet (chap. 18)
Low humidity and temp. accuracy. Fan speed has been reduced.
Set fan speed to 100%.
Controller
No cabinet function
(dark display).
Display in standby mode.
Press on touchscreen.
Main power switch turned off.
Turn on the main power switch.
Menu functions not available.
Menu functions not available with
current authorization level.
Log in with the required higher
authorization.
No access to controller
Password incorrect.
Contact your local Datacolor ser-
vice representative.
Chart recorder function: meas-
ured-value memory cleared; in-
formation lost.
New setting of storage rate or
scaling (minimum and/or maxi-
mum) (chap. 16.2).
Change the storage rate or scal-
ing ONLY if the previously regis-
tered data are no longer required.
Controller does not equilibrate to
setpoints entered in Fixed value
operation mode
Controller is not in Fixed value
operation mode.
Change to Fixed value operation
mode.
Controller does not equilibrate to
program set-points.
Controller is not in program oper-
ation mode, or program delay
time is running.
Start the program again. If ap-
propriate, wait for the program
delay time.
Program duration longer than
programmed.
Tolerances have been pro-
grammed.
For rapid transition phases, do
NOT program tolerance limits in
order to permit maximum heating,
refrigerating, or humidification
speed.
Program keeps the last program
setpoint constant while in setting
“ramp”.
Program line with setting “ramp”
is incomplete.
When programming with setting
“ramp”, define the end value of
the desired cycle by adding an
additional section with a section
time of at least one second.
Ramp temperature transitions are
only realized as steps.
Setting “step” has been selected. Select setting “ramp”.
Humidity alarm when operating
without water connection.
Humidity control turned on.
Turn off humidity control (chap.
6.3).
Acknowledging the alarm does
not cancel the alarm state.
Cause of alarm persists.
Remove cause of alarm. If the
alarm state continues, contact
your local Datacolor service rep-
resentative.
Alarm message:
- - - -
or <-<-<
or
>->->
Sensor rupture between sensor
and controller or Pt 100 sensor
defective.
Contact your local Datacolor ser-
vice representative.
Short-circuit.
Miscellaneous
Fluorescent tube does not illumi-
nate.
Defective fluorescent tube.
Replace the fluorescent tubes.
Impaired valve function of hose
burst protection.
Calcification.
Remove calcifications by citric
acid or acetic acid solutions
(chap. 4.3.1).
Have a plumber inspect the valve.
