ENGLISH
GENERAL INFORMATIONS
WHAT IS THE USE
EC 5-132 is an ON-OFF two outputs digital thermoregulator able to cover a temperature range
from -99 to +999 °C (-99 to +999 °F).
In factory the instrument gets preset to accept at the measure input PTC/NTC probes or “J”/”K”
thermocouples or 2/3 wires Pt 100 probes or 2 and 3 wires 0/4-20 mA temperature transduc-
ers (in this last case it is possible to set the reading scale).
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 “cooling” or “heating” functioning), with “neutral
zone” functioning.
EC 5-132 is available in the 72 x 72 mm (2.83 x 2.83 in., cylindrical housing) case with type of
protection IP 65 and it is studied for panel mounting with the equipped screw bracket.
GETTING STARTED
INSTALLATION
EC 5-132 was studied for panel mounting, panel cutout Ø 60.5 mm (2.38 in.), with the equipped
screw bracket (the overall dimensions and the panel cutout are related in Fig. 3, the fixing
system suggested by the builder is related in Fig. 4).
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.
ELECTRICAL CONNECTION
EC 5-132 is provided with two extractable screw terminal blocks for cables up to 2.5 mm²
(0.38 in.², for the connection to the power supply, measure input and outputs), located on the
instrument back panel (the connections to derive are related in Fig. 5 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 15 and 16 are derived to the local power supply, even if the instrument is
apparently turned off
- give the probe a protection able to insulate it against possible contacts with metal
parts or use insulated probes
- 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
- if you have any questions or problems concerning the instrument please consult
Every Control (see the chapter BUILDER DATA).

USE
PRELIMINARY INFORMATIONS
After derived the connections related in Fig. 5, during the normal functioning the instrument
displays the temperature read by the probe.
Fig. 2
iu5132.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 5-132 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 one’s
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 temperature read by the probe reaches the working setpoint and
when it rises above (if the outputs were set for “cooling” functioning) or it falls below (if the
outputs were set for “heating” 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 temperature 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 temperature 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 TEMPERATURE)
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 1
