1.2.2 Voltage measuring inputs
NOTE
The SPM-D10B/PSY4 can operate (monitor) only one synchronization point. The voltage at
terminals 23/24 (system 1) is the voltage to which the assessment of the synchronization at
terminals 20/21 (system 2) refers. The synchronization voltage can be, e. g., the mains or busbar
voltage.
NOTE
There are generally three different variants for connection of the measuring circuit voltage:
Direct connection to the low voltage system,
Connection to medium voltage via two-pole isolated transformer (e. g. in the case of a
V-connection) and
Connection to medium voltage via single-pole isolated transformer (e. g. Y-connection).

Conditions The function of the device is also dependent, apart from the discrete input signals, on
the state of the available measured voltages. The particular function must also be ac-
tivated in configuration mode:
Condition
ASynchronization
CB - for voltages of system 1 and 2 must apply 50 % < V < 125 % of the rated voltage VN
80 % f < 110 % of the rated frequency fN
(after respond of the time monitoring the synchronization will be
interrupted)
BBlack start
CB - Parameter "Black start ON“ - Voltage of system 1 must be smaller than 5 % of the rated vol-
tage.
- Voltage and frequency of system 2 must be within the configured
limits for black start.
CNo-load operation - Parameter "Automatic no load control ON"
- valid for f control:
Voltage system 2 > 50 % rated voltage VN
- SPM-D10B/PSY4-FU-D only - valid for V control:
Frequency system 2 > 90 % of rated frequency fN
DIsolated operation - Voltage system 2 > 50 % rated voltage VN
- SPM-D10B/PSY4-FU-D only - valid for v control:
Param. “Voltage controller in isolated operation ON”
2.2 LED "Closed" flashes
Incorrect signal state of the "Reply: CB is open" on terminal 4.
Possible faults:
- Reply present (= 0 V)
voltages system 1 and system 2 not synchronous
- Reply missing (= 24 V)
voltages system 1 and system 2 synchronous
If the LED is flashing, one must check to see whether the input on terminal 4 is cor-
rectly wired. For the wiring to be correct, there must be a closed power circuit
breaker on the input in question 0 V.

2.3 Control inputs
Enable CB
Terminal 3 Release for operation of the power circuit breaker
To enable the synchronization operation or a black start, this input must be set.
Reply: CB is open
Terminal 4 With this input the unit is signaled the status of the power circuit breaker. The input
must be set if the circuit breaker is open. (The status of this input is proved on plau-
sibility and is signaled by LED “Closed”.
Enable isolated operation
Terminal 5 Set.................•Enable frequency/voltage control in the case of missing "Reply:
CB is open" (the LED "Closed" on the front lights up).
•Enable black start for present "Reply: CB is open" (the LED
"Closed" on the front does not light up).
Reset.............•Shut down frequency/voltage controller in the event of a missing
"Reply: CB is open" (the LED "Closed" on the front lights up).
2.4 Control outputs
Command: close CB
Terminals 14/15 By setting this relay the power circuit breaker (CB) will be closed. The relay drops
out after the pulse is output.
Readiness for operation
Terminals 18/19 The relay contact is closed if the unit signals readiness for operation. The relay
drops out if one of the following events occur:
a) The internal self monitoring has indicated a fault. Then a proper working of the
unit can not be guaranteed and from other side appropriate steps must be taken.
b)The synchronization time monitoring is switched on and has responded.
2.5 Potential separation between the power supply and the discrete inputs
By means of an appropriate external wiring, the common reference point of the dis-
crete inputs (terminal 7) can be electrically isolated from the supply voltage (0 V, ter-
minal 2). This is necessary, for example, if the discrete inputs are not to be driven
with +24 Vdc and an electrical isolation of the control voltage (e. g. 220 Vdc,
220 Vac) must be guarantee for the power supply.
Wiring should be made as follows:
•Reference points connected with 0 V:
Bridge between terminal 7 and terminal 2 (0 V)
•Reference point of the discrete inputs potential-free:
Terminal 2: 0 V (Power supply)
Terminal 7: 0 V or N (control voltage)

2.6 Operating states
2.6.1 No load operation
The frequency and the voltage (SPM-D10B/PSY4-FU-D only) of system 2 are con-
trolled to the configured setpoint value by operating accordingly the relays of the
three-position controller for speed and voltage (SPM-D10B/PSY4-FU-D only; see al-
so chapter 2.1 "Function table" on page 7). The circuit breaker is open.
2.6.2 Synchronization
The voltage of system 2 is controlled to the voltage of system 1 in its frequency and
amplitude (SPM-D10B/PSY4-FU-D only) by operating accordingly the relays of the
three-position controller for speed and voltage (SPM-D10B/PSY4-FU-D only). With
consideration of the switcher time element the add-on command for the circuit break-
er is output in the synchronous point. The synchronization occurs under the following
conditions (see also chapter 2.1 „Function table“ on page 7):
•The unit is in automatic mode,
•the synchronous function is set,
•the frequency and the voltage (SPM-D10B/PSY4-FU-D only) are within the prede-
termined limits (see also chapter 2.1 “Function table” on page 7),
•the input "Enable CB" is set and
•the input "Reply: CB is open" is set,
•the synchronization time monitoring is not set or has not responded.
2.6.3 Black Start
Output of a add-on command for the circuit breaker without synchronization, if the fol-
lowing conditions are fulfilled:
•The unit is in automatic mode;
•the parameter "black start" has been set to "ON",
•the voltage of system 1 is not available (USystem1 < 5 % UN),
•the voltage and frequency of system 2 are within the configured limits,
•the input "Isolated operation" is set,
•the input "Enable CB" is set and
•the input "Reply: CB is open" is set.
2.6.4 Isolated operation
The frequency and the voltage (SPM-D10B/PSY4-FU-D only) of system 2 are con-
trolled on the configured set value by operating accordingly the relays of the three-
position controller for speed and voltage (SPM-D10B/PSY4-FU-D only;see also
chapter 2.1 "Function table" on page 7). The circuit breaker is open. To activate the
voltage controller the parameter "Voltage controller in isolated operation" has to be
configured to ON (SPM-D10B/PSY4-FU-D only).

4.1 Password protection
The unit is equipped with a three-level code and configuration hierarchy, which
enables it to visualize various configuration screens for different users. A distinction
is made between:
Code level 0 User: Third party
(CS0) This code level enables no access whatsoever to the parameters.
Code level 1 User: Customer
(CS1) This code level entitles the user to change a few selected parameters. Changing a
password is not possible in this case.
Code level 2 User: Commissioner
(CS2) With code level 2 the user acquires all access rights, and therefore has direct access
to all parameters (displaying and changing). In addition, the user may also set the
password for levels 1 and 2 in this level.
Enter code
number XXXX
Enter code number 0..9999
On accessing the configuration mode, a code number, which identifies the various
users, is first requested. The displayed number XXXX is a random number (RN). If
the random number is confirmed by “Select” without changing the item’s code level
remains as it was. If the code number of level 1 or level 2 is input, the unit changes
into code level CS1 or CS 2 and accordingly the parameter can be changed. If an
incorrect code number is input, the code level is set to code level 0.
NOTE
Two hours after input of the code number the code level returns automatically to CS0!
The present code number for code level 1 (CS1) is "0001" !
The present code number for code level 2 (CS2) is "0002" !
Only in code level 2 the pass word protection can be switched off!
Password
Protection ON
Password protection ON/OFF
ON............Access to configuration is attained by entering the appropriate password
(Code level 0/1/2). If an incorrect code number has been entered, confi-
guration is blocked.
OFF ..........Access to configuration screens is permanently set to code level 2 and
the code number is not queried.

4.3 Controller configuration
The parameters of the controller are modified by entering values in the following
screens.
WARNING !
An incorrect input can lead to uncontrolled controller actions and destroy the generator!
4.3.1 No-load control
Automatic idle
Running ON
Automatic no-load control ON/OFF
ON............With the circuit breaker open and no release of the circuit breaker, fre-
quency and if applicable voltage are controlled (see also chapter 2.1
“Function table” on page 7).
OFF ..........With the circuit breaker open, frequency and if applicable voltage are
controlled according to the following conditions (see also chapter 2.1
“Function table” on page 7):

4.3.2 Frequency controller
Freq. controller
ON
Frequency controller ON/OFF
ON............The frequency of system 2 is controlled. The frequency is controlled in
various manners depending on the task (isolated operation / synchroni-
zation). The subsequent screens of this option are displayed.
OFF ..........Control is not carried out, and the subsequent screens of this option are
not displayed.
Freq.controller
Ramp 00,0Hz/s
Frequency controller setpoint ramp 0,1..99,9 Hz/s
The change in setpoint is supplied to the controller via a ramp. The slope of the
ramp is used to alter the rate at which the controller modifies the setpoint value. The
more rapidly the change in the setpoint is to be carried out, the greater the value in-
put here must be.
Freq. controller
Dead band=0.00Hz
Frequency controller insensitivity 0.02..1.00 Hz
Isolated operationThe setpoint frequency of system 2 is controlled in such a man-
ner that, in its adjusted state, the actual value deviates from the
setpoint frequency setting (setpoint from mask setting) by the set
sensitivity value at most.
Synchronization...The frequency of system 2 is controlled in such a manner that, in
its adjusted state, the differential frequency reaches the set sen-
sitivity value at most. The frequency of system 1 is used as the
setpoint value increased by the value of the adjustable offset.
Freq. controller
Time pulse>000ms
Minimum frequency controller ON period 10..250 ms
The minimum ON period of the relay should be selected in such a manner that the
downstream adjustment facility responds reliably to the pulse that has been set ac-
cording to the set time. The smallest possible time must be set in order to ensure op-
timum control behavior.
Freq. controller
Gain Kp = 00.00
Frequency controller gain 0.1..99.9
The gain factor Kpinfluences the operating time of the relays. By increasing the fac-
tor, the operating time can be increased in the event of a certain control deviation.

4.3.3 Voltage controller (SPM-D10B/PSY4-FU-D only)
Volt. controller
ON
Voltage controller ON/OFF
ON............Generator voltage control is carried out. The generator voltage is con-
trolled in various manners depending on the task (no load / isolated op-
eration / synchronization). The subsequent screens of this option are
displayed.
OFF ..........Control is not carried out, and the subsequent screens of this option are
not displayed.
Volt. controller
Isolated op. ON
Voltage controller isolated mode ON/OFF
ON............In the operation mode isolated operation the voltage controller is acti-
vated.
OFF ..........In the operation mode isolated operation the voltage controller is inac-
tive. The frequency controller is not affected by this setting.
Volt. controller
dead band= 00.0%
Voltage controller insensitivity 0.1..25.0 %
The dead band given in % is related to the voltage transformer rated value of the
voltage system 2.
No load/Isolated operation The voltage is controlled in such a manner that, in its
adjusted state, the actual value deviates from the setpoint vol-
tage setting (setpoint from mask setting) by the set sensitivity
value at most.
Synchronization...The generator voltage is controlled in such a manner that, in its
adjusted state, the differential voltage reaches the set sensitivity
value at most. The mains or busbar voltage is used as the set-
point value.
Volt. controller
time pulse>000ms
Minimum voltage controller ON period 20..250 ms
The minimum ON period of the relay should be selected in such a manner that the
downstream adjustment facility responds reliably to the pulse that has been set ac-
cording to the set time. The smallest possible time must be set in order to ensure op-
timum control behavior.

4.3.4 Synchronization functions
Synchronizing
functions ON
Synchronization functions ON/OFF
ON............A synchronization of the frequency of system 1 is carried out. The add-
on command for the CB is carried out with little positive slip. The subse-
quent screens of this function are displayed.
OFF ..........No synchronization occurs, and the subsequent screens of this function
are not displayed.
Synchronizing
df offs.= 0,00Hz
Offset frequency 0.00..0.25 Hz
During synchronization the setpoint value of the frequency of the system 2 is calcu-
lated out of the frequency of system 1 added by this offset. This offset should be at
least 0.1 Hz smaller or half the value of dfmax (next parameter). Please also note
the setting of the insensitivity of the controller, too.
Synchronization
df max = 0.00Hz
Max. perm. differential frequency for synchron. (pos. slip) 0.02..0.49 Hz
The prerequisite of a connect command's being output is negative deviation from
this set differential frequency. This value specifies the upper frequency (positive val-
ue corresponds to positive slip).
frequency of system 2 is larger than frequency of system 1.
Synchronization
df min = 0.00Hz
Max. perm. differential frequency for synchron. (neg. slip) 0.00..-0.49 Hz
The prerequisite of a connect command's being output is negative deviation from
this set differential frequency. This value specifies the lower frequency (negative
value corresponds to negative slip).
frequency of system 2 is smaller than frequency of system 1.
Synchronization
dU max = 00.0%
Max. perm. differential voltage for synchronization 0.1..15.0 %
The dead band given in % is related to the voltage transformer rated value of the
voltage system 2.
To ensure that a connect command will be issued, the actual value must fall below
the entered differential voltage.
Synchronization
Time pulse>0.00s
Min. pulse duration of connect relay for synchronization 0.04..0.50 s
The duration of the connect impulse can be adjusted to the subordinate switching
unit.
Closing time
CB =000ms
Inherent delay of the CB for synchronization 40..300 ms
The inherent switching time of the circuit breaker corresponds to the lead time of the
connect command. The connect command will be issued at the entered time before
the synchronization point.
