General information:
The CDMR-62 is a digital line monitoring relay on a micro-controller basis with high measuring accuracy and 13 monitor-
ing functions, which are designated by the following abbreviations:
U< ... Undervoltage stage 1 f< ... Undervoltage stage 1 Vk> ...Vector shift
U<< ... Undervoltage stage 2 f<< ... Under frequency stage 2 Asy ... Voltage asymmetry
U<<< Undervoltage stage 3 f> ... Overfrequencies stage 1 Wsy ... Angle asymmetry
U> ... Overvoltage stage 1 f>> ... Overvoltage stage 2 DRE ...Rotational direction
U>> ... Overvoltage stage 2
Relay configuration
See Fig. 3 and Fig. 4 as basic information for configuration through the front control panel, see page 8 for configurations
through serial interface.
1. Information: The standard display with the current line values appears when connect-
ing the auxiliary voltage. Starting with this menu, the arrow keys can be used to browse
through all main menus. Using the ENTER button, one gets from the main menus to the
chain of detailed menus
2. 1st Step: Setting the grid type (3/4-wire grid) in the menu block "General settings".
These settings must be established at the start because different data records are allo-
cated to the 3-wire and 4-wire grid voltage monitoring.
3. 2nd Step: Activation and parameterizing of the required monitoring functions:
Selection of the appropriate main menu (example left U<<). The main and detail menus
always include the abbreviation of the respective switching step in the upper right area.
The output relays, which act on the switching stage (e.g. "K1__4_" with effect on K1 and
K4), are always listed on the second line
4. Information: A switching stage is inactive if no output relay is allocated to it (dis-
play "K_____" in main menu).
Change of the setup values, see page 5.
Settings for 3-wire or 4-wire grid
The star voltages are monitored in the 4-wire grid. The triangular voltages are monitored in the 3-wire grid, the star point
will be created internally. The limit values (U<<< ...U>>, Asy) for the star and triangular voltages are stored independently
from each other. Depending on the selected grid type, only the star or the triangular voltage limits are visible and adjust-
able at the CDMR-62 as well as in the PC parameterizing program.
Connection to a 1-phase grid: Connect voltage to the inputs L1, L2 and L3, grid type = "4-wire".
Voltage monitoring U<<<, U<<, U<, U>, U>>
Voltage measurement (root mean square values, digital harmonic filter) includes the star voltages and the phase-to-
phase voltages. The monitoring is sensitive to individual phases (U< excitation if at least one phase is below the limit
value, U> excitation if at least one phase is above the limit value). The undervoltage triggering can be blocked through
input "B" (see section "External blockade input"). When using the measuring voltage as auxiliary voltage, then the mes-
sage relays for U<, U<< or U<<< must be operated inverted, because otherwise undervoltage cannot be reported if the
auxiliary voltage fails.
Important: At least one undervoltage stage >= 70% must be set for standard grid parallel operation applications
because the frequency and vector shift triggering will be blocked below 70%Un and because otherwise there
would be a voltage range for which no triggering can be performed.
Special function: 2-phase sensitivity for the U< switching stage
This special function can be activated using the parameter "U< Trip Logic" in the menu block "General settings".
U< Trip Logic = OFF: Individual phase sensitivity U< Triggering, if at least one phase
undershoot the limit value.

Mains monitoring relay CDMR-62 / Operating instructions Page 5
CDMR62e_man_A1.doc
U< Trip Logic = ON: 2-phases insensitivity, U< triggering is only performed if at least two
phases undershoot the limit value.
Voltage asymmetry Asy
The asymmetry monitoring is triggered if at least one difference between the three star or triangular voltages exceeds
the set limit value (independent of the absolute voltage values, is also triggered, for example, in case of an individual
phase failure).
Phase Angle Asymmetry Psy
Adjustable limit value = deviation from 120°
The angle asymmetry is triggered if one of the three phase angles deviates from 120° by more than the set degree value.
Example: Setting value = 4°, tripping at phase angles <= 116° and >=124°.
The Angel measurement is only possible for 4-wire grids and correct rotating fields. Therefore, the setting menus for Wsy
will not be displayed for 3-wire grid types. The current angles are displayed in the menu "Line: Lxy angle"
(see Fig. 3).
Frequency monitoring f<<, f<, f>, f>>
The frequency monitoring is performed for three phases and it is active as long as at least one phase exceeds 0.7Un.
The frequency triggering will be blocked if all phase voltages are below 0.7Un. The frequency triggering can selec-
tively also be blocked through input "B" (see section "External blockade input").
Vector surge Vs>
Vector surge monitoring is carried out independently in each line. Tripping execution depends on the logic combination
selected in the menue "Vector Surge Vs> \ Trip Logic Vs>": (parameter value = 1 ... 9):
Value Logic Comment
1 "L1 " tripping on Vs> in line L1 (independent of L2 and L3)
2 "L2 " tripping on Vs> in line L2 (independent of L1 and L3)
3 "L3 " tripping on Vs> in line L3 (independent of L2 and L3)
4 "L1,L2,L3" tripping on Vs> in line L1 or L2 or L3 (inclusive "or")
5 "L1+L2 " tripping on Vs> in line L1 and L2 (independent of L3)
6 "L1+L3 " tripping on Vs> in line L1 and L3 (independent of L2)
7 "L2+L3 " tripping on Vs> in line L2 and L3 (independent of L1)
8 "L1+L2+L3" Tripping on Vs> in line L1 and L2 and L3 (within two periods)
9 "OFF " Vs> tripping disabled
The VS> excitation in an individual phase will be blocked if the phase voltage is below 0.7Un.
In addition, the Vs> triggering will be blocked for the set blockade time "t-Blockade Vs" if the auxiliary voltage is switched
on as well as if the measuring voltage will be connected. In addition, Vs> the triggering can be blocked externally (float-
ing contact) through the blockade input "B". After opening the contact, waiting for the blockade time "t-Blockade Vs"
expiration takes place until the monitoring is activated.
The length of the Vs> tripping signal is selectable in the menue "Vector Surge Vs> \ Pulsewidth... Vs>"
Phase sequence SEQ
The phase sequence (L1-L2-L3) is checked once on the rising of all 3 line voltages above 60%Un or in the case of
power-on of the supply voltage. A wrong phase sequence forces the assigned relay(s) to be permanently in the alert
state. The display shows the message: "PHASE SEQUENCE L1-L2-L3 fault!"
Change of setup values
See also Fig. 3 and Fig. 4 Page 10 and 11
1. Select the main menu of the required switching stage (e.g. U<).
(Starting in the grid menu by pressing the "UP/DOWN" arrow buttons simultaneously)
2. Using the "ENTER" button browse through the detail menu of the switching stage until
the required parameter. The switching stage symbol is always located in the upper right
area of the display field. The setup a range is shown in brackets, the set value is displayed
in the right lower area.

3. Press the "M/V" button Switches the function of the arrow keys from "Menu scrolling " to
"Value changing"). Now there may be two situations:
Case a): no security code is selected (Code = 000): A "release menue" (see left drawing) is
displayed, "xxx" is a self-incremented change-access counter. Confirm the change-access re-
lease with the ENTER key. (If you entered this menue inadvertently you may escape from the
menue with “UP/DOWN”arrowkeys).
Case b): Change release for an activated combination lock, the first digit flashes.
(If you got to this menu by accident, then please leave it by using the "M/V" button.)
Otherwise, using the "UP/DOWN" button, set the first digit correctly and press ENTER.
The second digit flashes now, adjust it, press ENTER and set the third digit. Complete with
"Enter".
4. Afterwards, the parameter menu will be displayed again and the first digit of the setup value
flashes. The decimal place can now be changed using the "UP/DOWN" arrow keys. (Automat-
ic increment or decrement if button is pressed). The next decimal place flashes after pressing
the ENTER button. After the last decimal place, the new value will be transferred into the
memory by pressing "ENTER" and the value will again be displayed static. (If the change must
be reversed, then the earlier value can be reestablished by pressing the "M/V" button instead
of ENTER).
After completing the change, one can transfer
- to the next menu using the "ENTER" or "DOWN" button,
- to the previous menu using the "UP" button,
- back to the line value display menu (= "Menu reset") pressing "UP" + "DOWN" simultaneously.
Assignment of output relays to individual monitoring functions and negation of output relays
Select the menu "Output-Relay nnn" of the respective switching stage (in accordance with step 1 to step 3 as above).
The switching stage U<< in the left example acts on the relays k1 and K4. The lowercase
letter for k1 shows that this relay is negated. It is energized in the normal state and released
in the tripped state. The "--" characters mark the positions of the (not assigned) relays
K2,K3 and K5.
4. After execution of step 3, the characters "k1" are flashing. The allocation of the U<< triggering with k1 can be deleted
or deactivated using the "UP/DOWN" buttons (in this case, the placeholder "--" is placed instead of "k1").
5. The settings for k1 will be accepted by pressing the "ENTER" button and the change mode will be switched forward to
K2, the placeholder for K2 flashes. Using this method, the positions for all 5 relays will be passed through.
6. After the completion for K5 (using the "ENTER" button), the "M/V" button can be used to start the change mode again
at k1, or a different button can be used to vacate the menu.
Negation of K1 ...K5 function
Select the menue "General Settings \ Negated Relays":
The configuration procedure is equivalent to step 4 - 6 above. An upper case character indi-
cates normal operation, a lower case character indicates negated operation. The relay codes
K1 -K5 are consecutively flashing and may be toggled between upper and lower case charac-
ter by “UP/DOWN” arrowkeys.
Security Code / Change-access release
To prevent unauthorized changing of setting values via the front panel, a three-digit security code can be stored in the
data memory. It has to be entered to get permission to alter parameter values.
If the security code is 000, the security sequence is not active and is replaced by a simple menue with a self-
incremented change-access counter (see step 3 above). The value of this counter may be used as indication of any
access to the change mode. The security code can be modified in the menue "General Settings \ Security code". Subse-
quent changing of the code is possible, but also in this case the active code has to be entered to get the permission for
changing.

The CDMR-61 is equipped with a real-time clock with a supply-buffer of 60 hours minimum. The time resolution is 1s.
Date and time of the internal clock are displayed in a menue of the "General Settings" chain. The clock settings may be
changed in this menue as well as by the PC program.
Clock setting by menue: see chapter "Change of setting values". The first flashing value is the "day", it may be incre-
mented or decremented with “UP/DOWN” arrowkeys, press ENTER key to step forward to "month" value and repeat
procedure till "seconds" value. After the last entry of the ENTER key flashing of seconds stops and the new date/time
settings are transferred to the realtime clock.
Event History Buffer featuring 100 events capacity
If the relay detects a fault-free line conditions (none of the selected monitoring functions energized) for more than 200ms,
the event trigger logic is activated waiting for the first tripping event. This event is recorded with date and time and the
corresponding line measurement values at the tripping instant. Up to 100 events are stored chronologically. On exceed-
ing this number the oldest event is overwritten.
The content of the history buffer may be displayed on the LCD panel or via the serial interface by a PC program. The
complete information of one event is splitted in two menues. From the menu "Event Monitoring" press the ENTER key to
branch to the:
1. Event menu
Hnn = Event number (H for "History", 00 = newest entry, 99 = oldest entry
U<<< tripping function
To display previous events press M/V key, "Hnn" flashes, now the event number can be scrolled from 00 to 99, the cor-
responding event information is instantly displayed. To check the measured values corresponding to any event,
press M/V key again to stop flashing then step to the 2. Event menue with the “DOWN” arrowkey :
2. Event menu
1. Line: Event number (Hnn) from the first event menu and tripping function,
2. Line: Measured values at the instant of tripping
The entries 00 to 99 can be selected using this menu. The flashing can be stopped – as explained above – for an inter-
esting event and a transfer to the event menu can be performed using the "Arrow up" button, which displays the date and
the time of this event.
Erasing the complete event history buffer:
In the menue "Event Monitoring \ H00-99 Erase" set the parameter value to 1. The erasing procedure takes about 30s.
Don't press any key during this procedure, cause it terminates the procedure in an incomplete state.
Blockage Time and Blocking Relay
Menu "General settings":
These two parameters can be used to adhere to the required brake time between a triggering event and the restart of the
circuit breaker without an external time relay The relay (K1..K5) defined as blocking relay will also be activated during
each triggering and the blockage time will be initiated. If the grid is faultless again, then the blockage time starts to run
and the blocking relay releases only after this time has expired. The blockage time is also effective after the relay power
supply has been connected and the grid is fault free.
External blockade input
Depending on the settings of the parameter “Ext. Blockade U,f" (in menue block "General settings"), the external block-
ade (see Fig.1, Connection "B" and "N" closed through floating contact, triggering time 40 ms) has the following effect:
„Ext.Blockade U,f“ Effect
0 .................... The blockade acts only based on the vector surge trigger "Vs".
1 .................... The blockade acts only on the excitation and triggering of Vs>, U<, U<<, f<, f<<, f>, f>>, Asy.
If the blockade is released and if a line fault is present, tripping is performed after the time
delay programmed for the corresponding monitor function.
2 .................... Blocking of all 13 monitoring functions. If blocking is released and a line fault present, tripping is
performed after the time delay programmed for the corresponding monitoring function.

Mains monitoring relay CDMR-62 / Operating instructions Page 8
CDMR62e_man_A1.doc
The relay has a self-monitoring program for error detection in the data memory (checksum er-
rors) which in the error case displays a message "DATA ERROR Parameter No. xxx". If the pa-
rameter "Selfmonitor.->K5" is set, the output relay K5 is changed to the alert state.
The number "xxx" in the display corresponds to the parameter number in the left column of table 1. If two numbers are
listed for one parameter, the first number refers to the corresponding star-type voltage, the second one to the corre-
sponding delta voltage. In the case of a checksum error of this kind, elimination may be successful by entering the pa-
rameter value once again (although the parameter value might be correct).
Parameter numbers 105 to 115 are used for internal scaling. In this case the unit has to be returned to the factory.
The K5 control circuit is designed to perform a watchdog function. If the K5 is configured as negated, it will be de-
energized not only in case of a data error or power supply failure, but also in case of a controller hardware failure.
Additional to self-monitoring the K5 can be assigned to any other monitoring function without restriction.
Use of the measuring voltage as auxiliary voltage
A measuring voltage in the range of 70 – 300 V AC is also permissible as an auxiliary voltage. However, it must be con-
sidered that all message relays transfer into the voltage-less condition in case the measuring voltage fails.
Parameterizing software for laptops
The serial interface offers a comfortable option for the parameterizing of the CDMR relay using a laptop or PC and to
document the set values. A special cable for the connection is available as an accessory.
User interface of the parameterizing program
Parameterizing the relay through a PC:
1. Load the parameter set into the PC: a) directly from the relay (PC menu: "Senden/Empfangen"/"Parameter
empfangen")
or b) from a data carrier with "Datei"/"öffnen" (file extension: ".par")
2. Set the parameter values and transfer to the CDMR ("Senden/Empfangen"/"Parameter senden")
The function of the CDMR is not impaired during the transfer of new parameters.
Exception: a short voltage triggering can occur when changing the grid type (3-wire and 4-wire grid).
Example of the content of the event
memory for the last 10 triggerings.
The triggering time and the meas-
ured values at this time are stored.
