ENGLISH
The electronic unit is a dual voltage device. This
means that the same unit can be used in 12V
or 24V power supply systems. Maximum volt-
age is 17V for a 12V system and 34V for a 24V
power supply system. Max. ambient temperature
is 55°C. The electronic unit has a built-in thermal
protection which is actuated and stops compres-
sor operation if the electronic unit temperature
gets too high (100°C/212°F on the PCB). It can
be connected to a PC through the Secop One
Wire/LIN Gateway communication interface on
the terminal D/I and C (Fig. 1). Communication
gateway modules incl. communication cables
can be ordered at Secop.
The PC interface allows you to create di󰀨erent
settings and reads out several measurements by
using the software tool TOOL4COOL® supplied
by Secop.
Installation (Fig. 3)
Mount the electronic unit directly on the compres-
sor plug and x it with screws.
Power supply (Fig. 1)
The electronic unit must always be connected
directly to the battery poles. Connect the plus to
+ and the minus to –, otherwise the electronic
unit will not work. The electronic unit is protected
against reverse battery connection. For protec-
tion during installation, a fuse must be mounted
in the + cable as close to the battery as possible.
A 15A fuse for 12V and a 15A fuse for 24V
circuits are recommended.
If a main switch is used, it should be rated to a
current of min. 20A.
The wire dimensions in Fig. 4 must be observed.
Avoid extra junctions in the power supply system
to prevent voltage drop from a󰀨ecting the battery
protection setting.
Battery protection (Fig. 2)
The compressor stops and restarts again accord-
ing to the designated voltage limits measured on
the + and – terminals of the electronic unit. The
standard settings for 12V and 24V power supply
systems are shown in Fig. 2. (PC option)
Other settings are (Fig. 5) optional if a connec-
tion which includes a resistor (R1) is established
between terminals C and P (non PC option).
Thermostat (Fig. 1)
The thermostat is connected between the termi-
nals C and T. Either a NTC (electrical thermostat)
or a mechanical thermostat can be connected.
Three di󰀨erent thermostat modes can be chosen
in the software - Auto (both NTC and mechanical),
NTC or Mechanical. Standard setting is Auto. In
case of using a NTC the set point in the range
between -40ºC and 40ºC is set with the software
and the temperature can also be seen by using
the interface. When using the Auto setting in the
software it is not possible to obtain NTC failures,
so it is recommended to set the thermostat mode
to NTC when using a NTC.
Setpoint selection (Fig. 6)
In order to utilize the nally intergrated tempera-
ture control. You can connect a 10kΩ potentiom-
eter between S and C (R2). Via this resistor a
temperature setpoint between -20°C and 10°C
can be selected. The compressor will stop when
the set point is measured on the NTC and re-
start at set point +1kΩ or 3K (Kelvin) (non PC
option).
Speed selection (Fig. 5)
The compressor will run with a xed speed of
4,000 rpm when the thermostat is switched on.
Other xed compressor speeds and start speeds
in the range between 2,000 and 4,000 rpm can
be obtained when changing the speed settings
in the software (PC option) or with the resistor
(non PC option).
A start delay in the range from 0-240 sec. (factory
setting 4 sec.) after thermostat cut-in can also be
chosen. By default the compressor will start with
a speed of 2,500 rpm for the rst 30 seconds.
Fan (Fig. 1)
A fan can be connected between the terminals
+(F) and F. Connect the plus to +(F) and the mi-
nus to F. Since the output voltage between the
terminals +(F) and F is always regulated to 12V,
a 12V fan must be used for both 12V and 24V
power supply systems.
The fan output can supply a continuous power
of 6Wavg. A higher current draw is allowed for 2
seconds during start.
Fan settings can be adjusted via TOOL4COOL®.
The factory default setting in the controller is:
Detect missing fan - Disabled.
The unit has to be restarted when these settings
have been changed. If a fan is used without ad-
apting the TOOL4COOL® settings, the fan will
run but no error signal will be sent in case of fan
failure. It is also possible to set a start delay on
the fan in the range from 0 – 240 sec. but only if
a fan is connected and not running.
Factory default setting for a fan is 0 seconds.
Fan speed can be adjusted through the interface
from 40 – 100%.
Error handling (Fig. 7)
If the electronic unit records an operational error,
the error can be read out in the software (PC op-
tion). Error codes are dened as shown in Fig. 7.
A 10mA light emitting diode (LED) can alterna-
tively be connected between the terminals D/I
and +. In case the electronic unit records an
operational error, the diode will ash a number of
times. The number of ashes depends on what
kind of operational error was recorded. Each
ash will last ¼ second. After the actual number
of ashes there will be a delay with no ashes,
so that the sequence for each error recording is
repeated every 4 seconds
(non PC option) .

(If the NTC thermistor is short-circuit or has
no connection, the electronic unit will enter
manual mode).
5Thermal cut-out of electronic unit
(If the refrigeration system has been too hea-
vily loaded, or if the ambient temperature is
high, the electronic unit will run too hot).
4Minimum motor speed error
(If the refrigeration system is too heavily
loaded, the motor cannot maintain minimum
speed at approximately 1,850 rpm).

(The rotor is blocked or the di󰀨erential
pressure in the refrigeration system is too
high (>5 bar)).

(The fan loads the electronic unit with more
than 0.65Apeak).

The communication port of the electronic unit
(terminal D/I and C) has two functions:
1. Communication mode (PC option):
The rst 15 seconds after power up/wake up, both
devices (compressor & PC) try to communicate.
In case a successful connection is made, the port
will stay in communication mode until next power up/
wake up.
2. Diode output mode (non PC option):
After 15 seconds with no communication link suc-
cessful established, the unit switches to diode output
mode.
No communication is possible until next power up/
wake up.
To ensure a trouble free connection using
TOOL4COOL®, the following method is recom-
mended:
Change the default TOOL4COOL® network setup
to allow TOOL4COOL® to search for the electronic
unit every 3 seconds. While TOOL4COOL® is sear-
ching, power up the electronic unit and wait for a
connection.
The following shows how to arrange this setup.
Preconditions:
The electronic unit is physically connected via the
gateway to the PC, but the power to the electronic
unit is not yet switched on.
In the example to the right, the electronic unit is con-
nected to the COM1 network.
Note:
Next to the USB connector of the gateway, there are
also two LED’s visible:
RED LED: blinks when TOOL4COOL® sends a
command to the electronic unit.
This must blink every second while TOOL4COOL®
is trying to establish a connection with the electronic
unit.
GREEN LED: blinks when the electronic unit re-
sponds to a TOOL4COOL® command.
The node address of the electronic unit must match
the command from TOOL4COOL®
(The network setting above tells TOOL4COOL® to
search for unit node address 1 every 3 sec.).
Instructions
Connecting TOOL4COOL®
to Electronic Unit 101N2130
Step Description / Display
1Do not power up the electronic unit at this stage.
2Start TOOL4COOL®
3In case the network is already connected, disconnect
it rst using on screen network option.
4Wait a few seconds, then select Connect Network
(below the File menu).
5Select the correct port, in this example COM1 is used.
6Cick Congure.
7Change Last network node address to 1and
change Refresh rate to 3.
Leave the other settings at their default value and
click OK twice.
Now TOOL4COOL® will only look for an electronic
unit with address 1, but every 3 seconds. This will
ensure that the connection is established within the 15
second time limit after powering up the unit.
Leave all other options unchanged.
8Power up the electronic unit
9The rst time the unit is connected, TOOL4COOL®
needs to obtain the parameter le from the unit before
a connection is shown by the red arrow. Allow a few
minutes for this task to complete.
You also can read the current status by selecting the
network and then select the tab Unit Status.
10 Look under Error/Message
In this example, no errors or messages appear and the unit is working properly.
11
If the parameter le was already loaded into
TOOL4COOL®, a connection should be visible in less
than 10 seconds.
A red arrow is added before the network name to
indicate that a unit is ready.
Click the red arrow to open
the menu of the electronic
unit.
