LED
- condensate drain solenoid valve on.
Through the digital thermometer with an alphanumerical display, the DMC14 controller shows the DewPoint
detected by the probe in the evaporator.
The LED
indicates any alarm conditions, that may occur when:
- DewPoint too high;
- DewPoint too low;
- the probe is damaged.
If the probe is damaged the instrument displays the message “PF” (Probe Failure), and the alarm goes off
immediately. In case of alarm for a very low DewPoint (ASL fixed parameter equal to -2°C) the signal is
delayed by a fixed time (AdL parameter) of 30 sec, whereas in case of alarm for a very high the threshold value
(ASH parameter) can be set by the user and delayed by an AdH value, which can also be programmed (the
instrument has default settings that are indicated below). As soon as the DewPoint falls back into the set
temperature range the alarm is disabled.
DMC14 allows also remote annunciation of the alarm condition of the dryer; this through a volt free contact on
terminals 8 & 9 - please also see electric drawings into the attachments (max 250V 1A, min 5VDC 10mA)
- with dryer off or in alarm conditions contact is open
-
with dryer on and correct operating DewPoint, contact is closed.
OPERATION -
After dryer starting, the electronic controller displays current operating DewPoint : it shows
the measured temperature in Celsius degrees (
●
°C
)
(
●
°C
) with a resolution of 0.5°C or in Fahrenheit (
●
°F
) with a resolution of 1°F.
The condensate drain solenoid valve is activated for 2 seconds (Ton) - LED (
●
) on - each minute (ToF),
if standard setting.
To perform the manual test for the condensate drain, press the
button.
SET-UP
To access the set-up, keep pressed simultaneously both
set
and
button for at least 5 seconds. In
this way
programming operation
will be activated and the controller display shows the first parameter that
can be set (Ton). After that, by pressing
set
button the display shows the value set for that parameter. If
the value is correct press
set
button to conferm it and to give access on following parameters. To change
the value of selected parameter, must be used
esc
and
button, respectively to decrease or increase
the value. All parameters that can be modified are indicated in following table:

It is possibile to exit from set-up conditon in any moment, by pressing simultaneously both
esc
and
button. If any operations are not made during 30 seconds, the controller exits automatically from
programming operation.
