3 Introduction
This instruction manual describes the installation and commissioning of the
Emotron DCM. The Emotron DCM is a control unit that remotely controls
submersible pump equipment. Level sensors are not needed to initiate start and
stop. The pump stops automatically when it begins to snore (draw air), when
the pit has been pumped free from water. During a pumping operation, the
Emotron DCM measures the length of the run period and uses this to determine the length of the rest period. The longer the run period, the shorter the
rest period. As a result the run and the rest periods are continuously adapted to
the rate of flow.
Two Emotron DCM can be connected in parallel to control two submersible
pumps and allow independent operation and display of monitored values (see
Chapter 7).
This instruction manual contains complete instructions for the installation and
use of the Emotron DCM. Please read the entire manual before installing or
using the DCM. Pay special attention to the Safety chapter in this manual and
the parts marked WARNING and CAUTION.
3.1 Description
The Emotron DCM measures the input power by measuring voltage and current. This gives a reliable measurement of pump motor load over the total load
range.
As an option a level switch can be used to trigger a start; either to override the
pause time in case of high level or as the sole means to trigger a start.
The Emotron DCM is connected to the pump motor supply cable with a type
CTM current transformer. The same Emotron DCM is suitable for small and
large induction pump motors and the only accessory needed is the CTM current transformer (a primary standard current transformer is also necessary when
the motor current is greater than 100 A).
The Emotron DCM is enclosed in a recyclable PC/ABS plastic housing. At the
front is the operator’s panel which comprises an LCD display and a set of six
keys. The connection terminals are at the top and bottom of the unit front
panel. The unit should be mounted on a standard DIN-rail.
The Emotron DCM is very easy to use. The “Auto set” function makes it possible to adjust the unit (stop level) automatically by pressing just one key.
Emotron AB 01-2120-01r2 Introduction 7
The Emotron DCM always stops the pump as soon as it starts to snore (draw
air) and restarts it after a calculated pause time or in response to a high-level
switch-over.
The Emotron DCM is able to check:
• Phase sequence.
•Phase voltage asymmetry.
• Current from current transformer(s).
• Temperature on pump motor.
• Undervoltage and Overvoltage (at start up).
The Emotron DCM gives information about:
• Delay time before restarting after the pump has stopped.
• Pumping time since the latest pump start.
• High-level pumping time since the pump started as a result of high-level
switch-over.
• Measured power as a percentage of the DCM’s measurement range.
• Measured voltage.
• Measured peak power as a percentage of the DCM’s measurement range.
• Time counter for total pumping time.
• Start counter - total number of times pump has started.
The Emotron DCM can be connected in parallel for a dual-pump system:
•Alternating
•MASTER/SLAVE function
• If there is a breakdown in one of the pumps, the other pump starts to
operate.

4 Getting Started
4.1 Please note the safety section
1. Pay special attention to the safety section in this manual and parts marked
WARNING and CAUTION.
2. Check that the pump motor/supply voltage corresponds to the values on the
Emotron DCM product label at the side of the unit.
3. Make a note of the pump motor’s rated current from its nameplate. Confirm
that the current transformer(s) supplied is of the correct size according to
Table 1, on page 15 and Table 2, on page 17 in this manual.
4.2 Connection and setup before start
1. Connect the Emotron DCM according to Chapters 5 and 6 and Fig. 13
(alternatively, for dual-pumps, Chapter 7 and Fig. 15 and 16).
2. Make sure all safety measures have been implemented and switch on the
supply voltage.
3. Follow Quick setup - flow chart Fig. 4, page 13 for single-pump system and
Fig. 5, page 14 for dual pumps.
The purpose of Getting Started is to achieve quick setup and to initiate the stop
function. The Emotron DCM stops the pump when the water level has
dropped to such a low level that the pump begins to snore (draw air). On intake
of air the pump motor power drops below the stop level (see Fig. 1, page 10 and
Fig. 2, page 11) and then the Emotron DCM stops the pump.

5 Installation
The Emotron DCM may only be installed and commissioned by an authorized
person according to standard and local regulations. Pay special attention also to
the Safety chapter in this manual and the parts marked WARNING and CAUTION.
The Emotron DCM should be mounted on a standard DIN rail 46277,
35 mm. See “Technical Data” for maximum operating temperature range,
dimensions etc. Before installing, make sure that no voltage is applied to the
equipment and that the voltage rating of the Emotron DCM, as shown on the
rating plate on the side of the unit, corresponds to the motor/line voltage.
5.1 Choice of current transformer
Depending on pump motor size, the Emotron DCM should be used with one
or two current transformers. For pump motors with a rated current up to
100 A, use a single CTM current transformer. The possible combinations of
CTM current transformers and the number of windings are listed in Table 1.

The following examples illustrate the choice of current transformer(s):
Example A. Pump motor has a rated current of 6.9 A. According to Table 1,
choose CTM010 with one (1) winding.
Example B. Pump motor has a rated current of 108 A. According to Table 2,
choose a standard current transformer 150:5 with one (1) winding and a
CTM010 with two (2) windings.
NOTE: The current transformer must be linked to the phase connected to
terminal 9 (L1).
In order to ensure accurate calibration of the Emotron DCM, it is essential that
you use the correct CTM (and, additionally, a standard current transformer)
and apply the exact number of wirings in accordance with the tables above.

5.2 The operator’s panel
The operator’s panel comprises an LCD display and a set of six keys on the front
panel of the Emotron DCM. The display provides five digits and eight symbols,
see Fig. 9. The symbols are explained in Table 3, page 20.
The two smaller digits on the left of the display show the window number. Each
window (e.g. 00, 01, 02) contains a parameter (e.g. 125, 0.99, on, OFF) whose
value is shown by the three larger digits or characters to the right. When the
value is greater than 999 all five digits are used to display the parameter value,
alternating with the window number. For example, the window number 21 is
displayed for 2 seconds and then the value 12345 is displayed for 2 seconds.

Emotron AB 01-2120-01r2 Single-Pump System Installation 27
6.1 Single-pump system connection
6.1.1 Supply voltage connection (L1, L2 & L3)
Connect the Emotron DCM (3-phase installation only) directly to the pump
motor supply cable via terminals 9 (L1), 11 (L2), and 13 (L3). Make the connection ahead of the contactor of the motor, to ensure that the DCM also
receives power when the motor is not in use. When motor fuses larger than
10 A are used, the DCM (power consumption 6 VA) must be fused independently, see Fig. 13, page 27.
6.1.2 Current transformer connection (S1 & S2)
Connect the current transformer CTM xxx to terminal 1 (S1, blue wire) and
terminal 2 (S2, brown wire). The transformer MUST be linked to the phase
connected to terminal 9 (L1), see Fig. 13.
When two current transformers are used (for motors with a rated current greater
than 100 A), always connect the CTM010 to the DCM and one outer standard
current transformer with 2 primary windings through the CTM010, see Fig. 8
and 13 and Table 2, page 17.
NOTE: Before connecting the current transformer(s), study the choice of
current transformers carefully to determine the correct number of
windings. The current transformer MUST be linked to the phase connected
to terminal 9 (L1), see Fig. 13, page 27.
In order to ensure accurate calibration of the Emotron DCM, it is essential that
you use the correct CTM and apply the exact number of windings in accordance with Table 1, page 15 or Table 2, page 17.
6.1.3 Alarm relay connection (ALARM & C)
Terminals 6 and 7 are the alarm relay connections. Terminal 6 (ALARM) is the

) if the pump
4. In window 22 set the maximum pause time between 0-720 minutes. See
section 6.4, page 32.
5. In window 23 set the required start-up delay between 1-170 s. Start-up
delay time is the time between the pump starting and the time when snoring
is detected (no liquid in the pit).
6. In window 24 set the required stop delay between 1-90 seconds. The stop
delay is the time between the pump starting to snore and the time when the
pump motor stops.
7. In window 31, if the pump has a temperature sensor and/or motor protection, set the temperature monitoring to (on). If not, set the window to
(OFF). See Section 8.5, page 42 and Fig. 13, page 27.

(on) or temperature alarm not latched (OFF). See section 8.5.
9. In window 41 the permitted phase asymmetry is set between 5% and 50%.
Phase asymmetry monitoring is turned off by pressing -, when the window
shows 5%. To turn the monitoring on again press + and select a value, see
Section 8.2, page 41.
10. In window 42, if the window 41 value is between 5% and 50%, choose
phase asymmetry alarm latched (on) or phase asymmetry alarm not latched
(OFF). See section 8.2.
11. In window 51 set the alarm relay contact function to NO (normally open)
or NC (normally closed), see Section 6.1.3, page 28.
12. In window 52 set the operating relay contact function, see section 6.1.4.
13. In window 53 set the required function for the digital input (DIG). Value:
(1) high-level switch, (2) external reset, (3) external Auto set.
14. Connect the start and stop equipment to terminal 8, see Fig. 13, page 27.
15. Check that the pump is pumping in accordance with the setting in window
13 (set the stop level in window 11 to 0 (default) if the pump stops before or
during the Auto set). Press the button and hold for 3 seconds until
“SEt” appears in the window. The stop level (window 11) becomes meas-
ured power (window 04) minus snore margin (window 12) if window 13 is

set to (
). The stop level (window 11) becomes measured power (window
04) plus snore margin (window 12) if window 13 is set to (_), see Fig. 2, 3,
12 and 14.
16. Change the level setting in window 21 between 1-10 for shorter or longer
pump cycles and levels in the pit. A low value gives shorter pump cycles and
lower level in the pit. See Fig. 11 and 14.
17. It is possible to avoid unintentional changes of set parameters. Set window
09 to 369 and confirm with . A padlock is shown in the window. If the
value 369 is re-entered in window 09, confirmed by , the settings are

6.3 Adjustment of stop level
The stop level can always be adjusted in the following way:
1. Change the snore margin (window 12) and perform a new Auto set. The
new stop level will be set in relation to the snore margin. See examples in
Fig. 2, page 11 and Fig. 3, page 12.
2. Change the stop level directly in window 11.
6.4 Start conditions and pause time
adjustment
In normal operation there are two starting options:
1. Pump start after remaining pause time (window 01).
2. Pump start at high level switch (window 53 = “1”). This requires connection
of a high-level switch according to Section 6.1.5, page 29.
The pump will also start if a non-latched alarm disappears or the button is
pressed during pause.
Calculation of pause time is based on previous pumping and pause times and is
controlled by the two parameters, level setting (window 21), and maximum
32 Single-Pump System Installation Emotron AB 01-2120-01r2
pause time (window 22). The parameters can be adjusted to achieve desired
ENTER
magnitudes of pause times, start level and number of starts per hour. See Fig.
11, page 23, and 14, page 32.
The level setting in window 21 is set for shorter or longer pumping and pause
cycles. Higher values increase the calculated pause time and the amount of accumulated water.
The level setting is best adjusted after a few pumping cycles in order to adjust
the pause time, and hence the start level in the pit. See schematic pump cycle
example in Fig. 11 and 14.
Maximum pause time for the pump is set in window 22. The calculated pause
time will be limited to this value. In some applications the inflow may increase
rapidly during a pause. To prevent overflow in these situations the maximum
pause time can be set in accordance with the circumstances.
6.5 Returning to the default settings
1. To return to the default settings go to window 99.
2. If any value differs from the default values (see Table 8). “Usr” (set by the
user) is displayed in the window.
3. Press to return to the default settings. “dEF” (default setting) is shown
in the window. Confirm by pressing .
NOTE: Also, windows 6, 7 and 8 are set to 0.

8 Protection and Alarm
When an error occurs, the triangular alarm sign starts to flash and the alarm
relay is activated.
Window 00 becomes active and gives the information about the alarm according to the alarm list, see Table 6, page 43.
Alarm in a dual-pump application
The fault code is shown in window 00 of the respective DCM, the alarm relay is
only set on terminal 6 of the DCM SLAVE when an error occurs. If a latched
alarm occurs it must be reset on the respective DCM by pressing the button or, if specified as digital input, by an external reset.
8.1 Phase sequence (F1)
When the DCM is first switched on, phases L1, L2 and L3 are checked for correct phase sequence.
If the wrong phase sequence is detected, an F1 alarm is generated and the
ALARM relay on terminal 6 is activated. The pump will not start. Switch the
power off and shift phase L2 and L3.
NOTE: Do not shift L1, only shift phase L2 and L3.
8.2 Phase asymmetry (F2)
The permitted phase asymmetry is set in window 41, see Table 8, page 53. Any
failure shorter than 5 seconds is ignored. When phase asymmetry is detected an
F2 alarm is generated and the ALARM relay on terminal 6 is activated. The
pump will be stopped.
If window 42 is set to on, the alarm can be reset by pressing the button or
by using the external reset signal.

When is pressed the DCM checks the measured current from the current
transformer (CTM), see Table 1, page 15 or 2, page 17.
The measured current at terminals S1 and S2 is displayed in window 61. If the
measured current is below 10 mA or above 60 mA, an F3 alarm is generated and
the alarm relay is activated. The pump will be stopped.
8.4 Operating fault (F4)
If the pump is snoring and the high-level switch gives the signal to pump, this is
a fault situation and an F4 alarm is generated and the ALARM relay is activated.
If communication between the DCM MASTER and the DCM SLAVE is interrupted an F4 alarm is generated and the ALARM relay is activated. See Fig. 16,
page 36 and Section 7.1.4, page 37.
8.5 Temperature input (F5)
Temperature monitoring on pump motor
The Emotron DCM can use either an input thermistor (PTC) signal or thermo
contact (terminal 5). To activate temperature monitoring, set window 31 to
“on”.
When the pump motor gets hot, the excess temperature generates an F5 alarm
and activates the ALARM relay and the pump will be stopped.
It is also possible to connect a motor protection relay to generate an F5 alarm.
See Fig. 13, page 27 and Fig. 16, page 36.
If window 32 is set to on, the alarm can be reset by pressing the RESET button
or by using the external reset signal.
8.6 Undervoltage (LU)/Overvoltage (OU) alarm
When the Emotron DCM is first switched on, the voltages on phases L1, L2
and L3 are checked.
If the wrong phase voltage is detected, an LU (undervoltage) or OU (overvoltage) alarm is generated and the ALARM relay is activated. The pump will not
start. Switch the power off. Check that the line voltage corresponds to the voltage range of the DCM according to the rating plate on the side of the unit.

pump
The pump continues to
run even if an alarm is
active.
Check that the current transformer(s) is/are linked to
the phase connected to terminal 9 (L1), see Section
6.1.2 and Fig. 13 or Section 7.1.2 and Fig. 16.
The power is represented as a value between 0-125%
of the “DCM’s power range”.
The DCM is designed to work with a pit volume which is
≥ the capacity of the pump (in litres), see Note on
page 22.
The capacity of the pump is too high. This will cause the
pump time to shorten compared with the pause time
(the pause time will lengthen). The calculated pause
time is based on previous pause time, actual pump
time and the setting of window 21 (1-10).
If alarm F4 (operating fault) has occurred, the pump will
continue to pump until the user resets the alarm.
