1. Applications, Functioning
The Signalling and Monitoring unit MU 1000C (named MU 1000C in the
following) is used as a central monitoring- and signalling unit in DC–power
supply systems. These plants can be battery-powered or can operate as direct
supply for DC-bus bars.
They are used in all the places, where plant information is collected (such as
voltages and current at different intersections of the system), where
parameters have to be monitored and errors signalled or when a boost charge
function or a discharge test is required in a battery system.
The mounting of the monitoring unit can be very universal. Thus it is just as
possible to mount it in 19” – complete slide-in units (above 3HE) as in a
19”- partial slide-in unit (with 1/3-19” width).
The individual signal parameters, like voltages and current, are connected over
secured lines directly to the MU 1000 over a plug (DIN41612, R48).
The MU1000 receives these values, indicates them on the display, compares the
values with adjusted monitoring thresholds, gives disturbance signals (LED +
relay) and operates in the boost charge operation as well as discharge test op-
eration as a controlling device for the connected rectifier.
Additionally the output values of rectifier REC and inverter INV can be read out if
CAN-bus is connected.
The user language can be selected over a parametric menu. All the necessary
monitoring parameters can be read by the end-user directly at the site of
application and can be adjusted over a code-protected service menu. Special
software adaptations are not necessary for this.
The MU 1000C can be obtained for 2 different voltage ranges and can be
directly connected to the corresponding DC potential without any further
measures.
The software as well as the default values for the plant parameters for the MU
1000C is programmed in an EPROM. The current values (adaptations on site etc)
as well as the error data are stored in an EEPROM.
If due to a defect in the MU 1000C, there is cancellation in the EEPROM, then
when the device is switched on again, there is a reprogramming with the
default values of the plant from the EPROM. During this reprogramming, all the
functions, which have a control, function for external devices (boost charge op-
tion, discharge test) are deactivated in order to prevent damage due to false
values in the plant. These functions must be manually activated again in the
service menu.

4. Description of the individual functions
4.1 Measuring inputs Udc1, Udc2, Udc3
•Voltage version 1 (LV): Operating voltage, measurement and indication of
24V-80VDC
•Voltage version 2 (HV): Operating voltage, measurement and indication
of 80V-300VDC
The supply lines have to be externally fused. If Udc3 is used for monitoring the
battery symmetry, pay attention to use the same reference connection point for
the minus connections of Udc1 and Udc3!
The clear text names for the display indication of the measuring inputs Udc1-Udc3
can be programmed via software (not included in this version) in the user menu.
The accuracy of the indication of the values corresponds to a class1 measuring
device.
Clear text terms:
•Udc1: freely programmable; designation in this version: Ubatt
•Udc2: not connected
•Udc3: not connected
4.2 Measuring inputs Idc1, Idc2, Idc3
The assignment of the nominal shunt values is done in the Service menu. The
following shunt magnitudes can be assigned to the individual measuring inputs:
•Idc1:(+/-)0-50A in 1A steps,50-1000A in 5A steps;0A means no sh.installed
•Idc2: 0-50A in 1A steps, 50-1000A in 5A steps; 0A means no shunt installed
•Idc3: 0-50A in 1A steps, 50-1000A in 5A steps; 0A means no shunt installed
The assigned maximum current of the shunt corresponds to a potential drop of
60mV.
As only the measuring input Idc1 can show negative current values, it should be
used for the reading of the battery charging- and discharging current.
The accuracy of indication of the values corresponds to a Class 1 measuring
instrument.
ATTENTION!
All shunts have to be referenced to the same DC-bar. A potential difference in
the current path of the shunts leads to failure of the measuring inputs.
A connection of the digital GND to the positive (in the direction of current flow)
connection at the current shunt is necessary for the correct indication of the
current measuring value. If more than one shunt is used in the system, then the
connection to one shunt is sufficient.

4.3 Monitoring the insulation error
The connection of the measuring and supply voltage Udc1 as well as of the
protective conductor is the minimum necessity for monitoring the DC-system for
insulation errors. While measuring the insulation error, it can be seen whether
there is an insulation error between the plus pole and the earth or the minus
pole and the earth.
Insulation errors are recognised only when they appear between the plus
potential/minus potential and the earth, not between the potentials.
The threshold value of the insulation resistance can be adjusted over the user
menu. The prefix indicates whether there is an earth-leakage against the plus or
minus.
Earth fault R = +(-)xxxkOhm
Factory setting: The error signal does not enter collective failure relay.
4.4 DC-Low voltage signal
A monitoring threshold U<Umin can be adjusted for each measuring voltage
(Udc1 to Udc3). The LED indication at the front side U>Umin and the relay K4 are
connected with the monitoring Udc1. In case of an error the Green LED U>Umin
goes out and the signalling relay K4 will switch over.
An external signal of the monitoring for Udc2 and Udc3 is possible over an
assignment of the signal to the reserve relay K1 or LED-signal S1 or S2.
A time-delay can be adjusted in the user-menu for these signals.
Indication: Udc1<Umin
Udc2<Umin
Udc3<Umin
4.5 DC- High voltage signal
A monitoring threshold U>Umax can be adjusted for each measuring voltage
(Udc1 to Udc3). The LED indication at the front side U>Umax and the relay K3 are
connected with the monitoring Udc2. In case of an error the red LED U>Umax
lights up and the signalling relay K3 pulls up.
An external signal of the monitoring for Udc2 and Udc3 is possible over an
assignment of the signal to the reserve relay K1 or to the LED-signals S1 and
S2.
A time-delay can be adjusted in the user-menu for these signals.
Indication: Udc1>Umax
Udc2>Umax
Udc3>Umax

4.6 Temperature control and temperature compensation of
the charge voltage
If an active temperature sensor (LM335) is connected to the monitoring unit,
then the temperature in the devices or the battery can be monitored. The signal
can be programmed as a collective failure (can be selected by the user) or be
conducted over the reserve relay K1 (can be programmed)
Thus the contact can be used for e.g. for a ventilation control. The temperature
monitoring can be activated in the service menu. The temperature threshold and
hysteresis can be similarly adjusted in the service menu.
Thus the contact can be used for e.g. for a ventilation control. The temperature
monitoring can be activated in the service menu. The temperature threshold and
hysteresis can be similarly adjusted in the service menu.
Indication: High temperature T>
The source tension of rectifier modules connected over CAN bus is steered
through choice of the option Temperature compensation dependent on tempera-
ture. The temperature coefficient as well as the start temperature and
final temperature of the loading tension regulation are programmable.
4.7 Mains voltage control
With additional board MU1000-MM (option) the unit monitors and displays the
mains voltages. The monitoring threshold is programmable in service menu.
Indication: UR US UT f
xxxV xxxV xxxV 50.0

Fault Indication: MM1 fault, mains fault V< or mains fault V>
With abandonment of the programmable supervision tension area a mistake
signal is generated. This mistake signal is filed in the event memory and can be
assigned to a Signal-LED (S1 or S2) as well as a registration relay.
The indicated frequency is measured by the phase L1.
4.8 Digital inputs
In total 8 digital inputs are available for different monitoring functions.
External relay contacts, like fuse monitoring are connectable to monitor and
signalling fault messages via MU1000C.

4.9 Additional Relays K1/K2 (K11-K18)
A signal can be assigned to the signalling relay K1 or K2 over the adjustments in
the service menu. If several signals are assigned, then the individual
signals are connected thus, the signalling relays switch when one or more of the
assigned signals appear. In the case of activated boost charge option, the relay
is assigned to the signal boost charge. Thus a battery compartment
ventilator can be operated over this contact. In this case, the other error
signals cannot be assigned to K1.
The falling-off of the relay is thereby delayed with entry of a mistake in the
opposed time. Put on the relay with discontinuation of the mistake condition
occurs against it undelayed.
All the individual signals can be assigned to the signalling relay K1.
For every relay a delay of 0-300 seconds can be programmed.
4.10 Monitoring: Battery unsymmetry
Defective battery cells can be recognised over the deviation of the mean voltage
of the battery (Ubatt/2) from the adjustment of the monitoring threshold dUbatt
and the mean voltage of the battery Ubatt/2 in the service menu. Only a very
high non-symmetry in the battery system is recognised and not the
position of the defective cell/s. The condition for this monitoring function is the
connection of the measuring voltage Udc3 between the minus potential and the
centre of the battery.
Setting occurs in % of the battery nominal tension (=cell count x 2.0V)
Fault indication: Battery unsymmetrical

4.11 Boost charging
There are different possibilities the boost charge (BC) to switch on.
Once about the manual activation. One must release the suitable point and then
can switch on in the main menu the BC with ENTER.
The BC can be also switched off so again.
To the second an automatic activation can occur.
One can let the BC by certain conditions one or also switch off.
e.g. BC switch On, if the battery tension is smaller of a certain one
Off tension value
or
if Ibatt (Ilade) > 200 A is.
The boost charge (BC) can be also released about a digital entrance (MU1000 or
I/O or DIG8).
The BC can be begun likewise automatically after a battery test.
If the BC is active, this is indicated in the main menu of the MU.
By a digital entrance one can switch off the BC or block also, so that the BC is
not switched on only at all.
There is furthermore a hand load where one can give by hand the tension.
Also a system charge is possible.
One can put a timer which switches off the BC after max. 1-24 hours.
4.12 Bootloader
From the firmware version MU 2.0 a Bootloader is integrated, i.e. you can carry
out over the CAN bus (with an USB-CAN-Dongle) or above the RS232
interface a firmware-update.

6.2 Service menu
The service menu is used for changing parameters in the MU 1000. It is
protected against unauthorized access by a 3-digit access code. For the
calibration of the voltage and current measuring inputs, a calibration menu can
be selected with a second access code (see Pt. 6.2.3.)
Only authorised technical personnel should do changes in the service menu
because wrong adjustments could damage the system, the connected battery
and the load device. Eltek Valere Industries does not warrant damages caused
by
incorrect operation of the MU 1000C or by changes in the service menu. The
menu is shown with a star “ * “ , because it has the sub-menu s.
The indication values and possible parameters / adjustment fields are program-
mable only by service personnel.
6.2.1. Customer menu
The customer menu is a kind of reflection of the service menu, i.e. all valid
values of the system are indicated. However, these values cannot be changed in
contrast to service menu. The menu point should serve to give a topical over-
view about the investment parameters to the customer or to allow a
detailed distant diagnosis in the mistake case.
The menu is shown with a star “ * “ , because it has the sub-menu s.
