WHAT IS THE USE
EC 3-432 is an ON-OFF two outputs digital humidity controller which reading scale is configurable.
In factory the instrument gets preset to accept at the measure input 2 and 3 wires 0/4-20 mA
humidity transducers like EC UMD 00 and EC UMD 01 and it is able to provide to the power
supply of transducers if they are studied to work with a voltage included from +9 and +16 V.
This device can be set to execute one of the following kind of regulation: with an independent
working setpoint and the second relative to the first, with two independent working setpoint (in
these two cases each output can be set for dehumidifying or humidifying functioning), with
neutral zone functioning.
EC 3-432 is available in the 74 x 32 mm (2.91 x 1.25 in.) case and it is studied for panel
mounting with the equipped screw or spring brackets.

INSTALLATION
EC 3-432 was studied for panel mounting, panel cutout 71 x 29 mm (2.79 x 1.14 in.), with the
equipped screw or spring brackets (the overall dimensions and the panel cutout are related in
Fig. 3, the fixing systems suggested by the builder are related respectively in Fig. 4 and in
Fig. 5).
ADDITIONAL INFORMATIONS
- the panel thickness must be included from 1 to 5 mm (0.04 to 0.19 in.)
- verify if the using conditions (ambient temperature, humidity, etc.) are within the
limits indicated by the builder (see the chapter TECHNICAL DATA)
- install the instrument in a location with a suitable ventilation, to avoid the internal
overheating of the instrument
- do not install the instrument near surfaces that can to obstruct the air-grating (car-
pets, covers, etc.), heating sources (radiators, hot air ducts, etc.), locations sub-
ject to direct sunlight, rain, humidity, excessive dust, mechanical vibrations or
bumps, devices with strong magnetos (microwave ovens, big speakers, etc.)
- according with the safety norms, the protection against possible contacts with
electrical parts and parts protected with functional insulation only must be ensured
through a correct installation procedure of the instrument; all parts that ensure the
protection must be fixed so that they can not be removed if not with a tool
- if not differently specified at the time of order, the instrument will be equipped with
screw brackets.
ELECTRICAL CONNECTION

connection to the power supply, measure input and outputs) and it is provided with one five
poles single line male connector (for the connection to the CLONE configurer/cloner and RICS
supervision systems), located on the instrument back panel (the connections to derive are
related in Fig. 6 and they are checkable on the polyester label stuck on the instrument case).
ADDITIONAL INFORMATIONS
- if the instrument is brought from a cold to a warm location, the humidity may con-
dense inside the instrument; wait about an hour before supply the instrument
- verify if the operating power supply voltage, electrical frequency and power of the
instrument correspond to the local power supply (see the chapter TECHNICAL DATA)
- do not supply more instruments with the same transformer
- if the instrument is installed on a vehicle, its power supply must be derived directly
from the battery of the vehicle
- give the instrument a protection able to limit the current absorbed in case of failure
- the instrument remains connected to the local power supply as long as the termi-
nals 8 and 9 are derived to the local power supply, even if the instrument is appar-
ently turned off
- give the outputs a protection able to protect them against short circuit and overload
- do not try to repair the instrument; for the repairs apply to highly qualified staff

PRELIMINARY INFORMATIONS
After derived the connections related in Fig. 6, during the normal functioning the instrument
displays the relative humidity read by the probe.
iu3132.wmf
If an alarm should be active the instrument displays the alarm code flashing and the buzzer
utters an intermittent beep as long as the cause that has given it does not disappear (see the
chapter SIGNALS AND ALARMS); pressure on the key T1 during an alarm permits to silence
the buzzer.
EC 3-432 is provided with two working setpoint and with some configuration parameters that
get stored in a non volatile memory and that permit to set the instrument according with ones
requirements (see the chapter CONFIGURABILITY).
During the regulations with an independent working setpoint and the second relative to the first
and with two independent working setpoint, the output K 1 is associated to the first working
setpoint, the output K 2 is associated to the second working setpoint, they remain activated
continuously as long as the relative humidity read by the probe reaches the working setpoint
and when it rises above (if the outputs were set for dehumidifying functioning) or it falls
below (if the outputs were set for humidifying functioning) the respective working setpoint of
the hysteresis value (differential) the outputs get reactivated.
During the regulation with neutral zone the output K 1 remains activated continuously as long
as the relative humidity read by the probe reaches the working setpoint and when it rises above
the working setpoint of the neutral zone value the output gets reactivated; likewise the output
K 2 remains activated continuously as long as the relative humidity read by the probe reaches
the working setpoint and when it falls below the working setpoint of the neutral zone value
the output gets reactivated.
WORKING SETPOINT SETTING (WORKING RELATIVE HUMIDITY)
To modify the first working setpoint value keep pushed the key T3 (the instrument displays the
actual value) and at the same time push and release over and over the key T1 or T2 as long as
the instrument displays the desired value (keeping pushed the key T1 or T2 the value gets
decreased or increased more quickly): after the modification release the key T3 last; for the
two seconds following the release of the key T3 the instrument displays the established value
and the LED L1 flashes quickly to indicate that a first working setpoint setting procedure is
running (passed the two seconds from the release of the key T3 without operated with the keys
the instrument automatically turns out from the working setpoint setting procedure).
To modify the second working setpoint value release and keep pushed the key T3 during the
flashing of the LED L1 (the instrument displays the actual value) and at the same time push
and release over and over the key T1 or T2 as long as the instrument displays the desired value
(keeping pushed the key T1 or T2 the value gets decreased or increased more quickly): after
the modification release the key T3 last; during the pressure of the key T3 the LED L2 flashes
quickly to indicate that a second working setpoint setting procedure is running (to the release
of the key T3 the instrument automatically turns out from the working setpoint setting proce-
dure).
ADDITIONAL INFORMATIONS
- for the whole period of a corrupted memory data alarm the access to the working
setpoint setting procedure is refused
- if the parameter -/0 has value the second working setpoint does not exist
- the first working setpoint is programmable within the limits established with the
parameters rA1 and rA2
- the second working setpoint is programmable within the limits established with the
parameters rB1 and rB2
1
- if the parameter rA5 has value 1 the first working setpoint can not be modified as

long as the parameter rA5 gets set to 0
- if the parameter rB5 has value 1 the second working setpoint can not be modified as
long as the parameter rB5 gets set to 0
- the working setpoint values get stored in a non volatile memory even if a lack of
power supply happens.
CONFIGURATION PARAMETERS SETTING
Configuration parameters are arranged on two levels, to protect the most tricky settings against
undesirable violations and they are arranged in families that can be recognized through the
initial letter of the label.
To gain access to the first level keep pushed at the same time for four seconds at least the keys
T1 and T2 (passed four seconds the instrument displays the label PA).
To select a parameter of the first level push and release over and over the key T1 or T2 as long
as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de-
creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To gain access to the second level enter inside the first level and select the label PA.
Keep pushed the key T3 (the instrument displays the actual value) and at the same time push
and release over and over the key T1 or T2 as long as the instrument displays -19 (keeping
pushed the key T1 or T2 the value gets decreased or increased more quickly): after the modi-
fication release the key T3 last (to the release of the key T3 the instrument displays the label PA
again); keep pushed at the same time for four seconds at least the keys T1 and T2 (passed four
seconds the instrument displays the first parameter of the second level).
To select a parameter of the second level push and release over and over the key T1 or T2 as
long as the instrument displays the label of the desired parameter.
To modify the parameter value keep pushed the key T3 (the instrument displays the actual
value) and at the same time push and release over and over the key T1 or T2 as long as the
instrument displays the desired value (keeping pushed the key T1 or T2 the value gets de-
creased or increased more quickly); after the modification release the key T3 last (to the
release of the key T3 the instrument displays the label of the parameter again).
To turn out from the configuration parameters setting procedure keep pushed at the same time
for four seconds at least the keys T1 and T2 or do not operate with the keys for fifty seconds
at least (time-out exit).
ADDITIONAL INFORMATIONS
- for the whole period of a corrupted memory data alarm the access to the configura-
tion parameters setting procedure is refused
- the modification of a parameter value which unit of measure is the hour or the
minute or the second has not immediate effect; to obtain this effect it must not be
executed during the course of the value
- the configuration parameters values get stored in a non volatile memory even if a
lack of power supply happens.

ALARMS
If the instrument displays the indication E2 flashing and the buzzer utters an intermittent
beep (corrupted memory data alarm) it means that there is a corruption of the configuration
data in the memory (turn OFF and turn ON again the instrument: if to the turning ON again the
alarm does not disappear the instrument must be replaced); during this alarm the access to the
working setpoint setting and the configuration parameters setting procedures is refused and
all outputs get forced to the status OFF.
If the instrument displays the indication E0 flashing and the buzzer utters an intermittent
beep (probe failure alarm) it means that: the kind of connected probe is not proper (see the
parameter /0), the probe is faulty (verify the probe integrity), there is a mistake in the instru-
ment-probe connection (verify the instrument-probe connection integrity), the relative humid-
ity read by the probe is outside the limits permitted by the probe in use (verify that the relative
humidity near the probe be inside the limits permitted by the probe); during this alarm the
output K 1 gets forced to the status established with the parameter CA3 and the output K 2 gets
forced to the status established with the parameter CB3.
If the instrument displays the indication AL1 flashing alternated to the relative humidity read
by the probe and the buzzer utters an intermittent beep (first relative humidity alarm) it
means that the relative humidity read by the probe is outside the limit established with the
parameter AA1 (see the parameters AA0, AA1 and AA4); inactive.
