1 APPLICATION
The KS5 digital synchronizing unit has been designed for the synchronization of
generators switched for parallel operation with the grid or with other generators with rated
frequency of 50 or 60 Hz. Frequency differences, voltage values, and phase shifts are shown
on a 3.5“ color TFT display screen with a resolution of 320 x 240 pixels.
Bar graphs with zero in the middle marked f and δU indicate respectively the difference in
frequency and the difference in voltage values of the generator and network signals. Phase
shift φ of the generator and network voltage signals is indicated by a circular
synchronoscope. The spin speed corresponds to the difference between the network and the
generator frequency.
The synchronization point, i.e. the moment when the frequency, voltage and phase values of
the generator and the network are equal, is indicated by green indicators on the bar graphs
and inside the circle. With proper control of the BLK and START signals (detailed in p.7.3),
the SYNC synchronization relay will be activated.
The values of the measured quantities and deviations can be transferred to the master
system via RS485 interface or Ethernet.
The synchronizing unit has a galvanic separation between the individual blocks of:
- power supply,
- voltage inputs,
- Input control signals,
- RS485 Interface,
- Ethernet Interface:
- relay outputs

3 BASIC REQUIREMENTS, OPERATIONAL SAFETY
In terms of operational safety the synchronizing unit meets the requirements of DIN EN
61010-1.
Safety instructions:
●The meter installation and connection should be made by qualified personnel.
All available protection requirements must be taken into consideration.
●Prior to turning the meter on verify the connections.
●Prior to removing the meter housing, always turn the supply off and disconnect the
measurement circuits.
●Removal of the meter housing during the warranty period voids the warranty.
●The synchronizing unit meets the requirements for electromagnetic compatibility in
industrial environment.
●A switch or a circuit-breaker should be installed inside the building or facility. It should
be located near the device, easily accessible to the operator, and suitably marked.
4 INSTALLATION
The synchronizing unit is adapted to be fixed to the panel by means of mounting brackets,
according to fig. 1. The housing is made of self-extinguishing plastic.
Fig.2. Meter fixing

KS5-09A User's manual 4
Housing dimensions 96 x 96 x 77 mm, mounting hole dimensions 92.5 x 92.5 mm. Outside the
meter there are screw terminals that allow connection of external wires with a cross-section up
to 2.5 mm2.

5 DESCRIPTION OF THE INSTRUMENT
5.1 Voltage inputs
Voltage inputs are galvanically isolated (internal transformers). Un voltages (phase or phase-
to-phase) are automatically recalculated by the input value of the external voltage transformer
ratio. The voltage inputs specified in the order as 50...150 V or 150...400 V are programmable
in the selected range. Maximum operating voltage relative to earth is 300 V.
5.2 External connections diagram
External connections are shown in Figures 4a, 4b.

6.1 General description
Fig.5 Front panel
KS5 synchronizing unit has 6 buttons and a graphical color display.
Description of the front panel:
V, Hz, °,%
units of displayed quantities
K
kilo = 103,
US, fS,
UG, fG
δf, δU, ϕ
Indications of displayed parameters
Input measuring signals:
US- network voltage, fS–network frequency,
UG- generator voltage, fG–generator frequency,
Input control signals:
BLK - synchronization lock (SYNC relay will not be activated even if the other synchronization
conditions are met)
START - start of synchronization - unlocking the SYNC relay. After the START signal, the
meter expects that measured values of the voltage δU and frequency δf difference and the
phase shift φ of the voltage signals from the generator and the network will be within the set
admissible values, then it generates a pulse that activates the SYNC relay with the set lead in
time.

KS5-09A User's manual 7
Output signals (relay contacts):
- AL - fault relay is activated in case of faulty external circuit connection when a fault occurs
and if the measured values are outside the measuring range,
- SYNC - synchronization relay,
Calculated values:
δf, δU- difference in frequency and difference of voltage values of the generator and
network signals,
ϕ- phase shift of the generator and network voltage signals,
The SYNC synchronization relay will be energized after synchronization conditions have been
met.
Synchronization conditions:
-δU≤ δU ≤ +δU
-δf≤ δf ≤ +δf
IϕI≤ Δϕ
BLK = "0"; START = "1" ( detailed description in p. 7.3 Relays )
where:
-δU -lower limit of voltage difference during synchronization,
+δU -upper limit of voltage difference during synchronization,
-δf - acceptable frequency difference when connecting "from below",
+δf - acceptable frequency difference when connecting "from above”,
ϕ−phase shift,
Δϕ −acceptable phase shift,
The difference in the values of the voltage and frequency of the generator UG,fGand network
US,fS is calculated according to the formulas:
δU = 100 (UG-US)/US[%]
δf = 100 (fG-fS)/fS[%]
The phase shift of the generator voltage UGrelative to the network voltage USis expressed in
degrees:
ϕ= (UG,US)[ ° ]
Fixed phase shift compensation: positive value means that the generator voltage UG is ahead
of the network voltage US.
Fig.6, Synchronoscope with phase shift visualization

KS5-09A User's manual 8
The spin speed and direction correspond to the difference between the network and the
generator frequency.

The values of measured parameters are presented on the next pages selected by pressing
the following buttons: (next page ) or (previous page).
Meter buttons can perform various functions depending on the operating location. Functions
are described on the bar at the bottom of the screen. If no description is present, it means that
the button is inactive at that moment.

6.2 Starting operation
When power is turned on, the synchronizing unit displays the logo, KS5 meter name, version,
current firmware version and MAC for versions with Ethernet, and then switches to
measurement mode. Displayed information:

7 CONFIGURATION OF THE METER
PARAMETERS
During normal operation (Measurement) the unit displays and signals the values that
characterize the state and the course of the generator synchronization process. The KS5
meter performs voltage measurement functions (voltage difference), frequency (frequency
difference), and phase shift between the voltage signals of the network and the generator.
The meter menu is divided into the following groups:
Parameters –configuration of parameters of the meter,
Relays –configuration of SYNC and AL relays,
Ethernet –configuration of Ethernet interface parameters,
Modbus –configuration of RS485 interface parameters,
Settings - settings: password, language, brightness level,
Information –preview of program version, serial no., MAC address,
To enter the parameter menu, press the button for about 3 seconds.

Access to configuration of parameters is protected by a password, if it has been
introduced and is different from zero. When the password is 0000, the password prompt
is bypassed. If the password is incorrect, the message "Invalid password. Read-only
menu.” is displayed. Then you can view the parameters, but the changes are blocked.
