Operating instructions
Automatic start/stop system for stand-alone gensets
for product: KEA 202 INS
File: BA_KEA 202 INS_EN_Ver 2016-07-01 (ersetzt Version 2014-09-18)
1. Use and basic operation
The KEA 202 INS automatic system is used in systems which are operated solely as standalone gensets.
Generator current sensor, overload, short-circuit, asymmetric load and the drag indicator display of the current
load are completeley integrated. The automatic control unit uses the RZ-071-D of KEA series 070. The addi-
tional relay unit RZ-071-E can be used as an amplification. Because the KEA 202 has the same dimensions
and fastenings as its predecessor, replacement is simple.
Four dedicated operating messages and four programmable operating displays can be labelled by replaceable
paper strips and are indicated by LEDs. All other alarms and all actual and reference values are shown on the
display. The illuminated display shows two lines with up to 16 characters with a character height of 10 mm so
that it can be read from a greater distance. The parameterisation can be carried out via the keys and the
display or via the serial interface (LWL) with the parameterisation program PARAWIN.
Two CAN bus interfaces are available for coupling to a ZLT and to a motor management system. However,
the protocol for the motor management system must be known and implemented.
The automatic system can be cost-effectively integrated in a communication system (KUHSE TELEMON) via the
public telephone or GSM mains by plugging in a modem.
Important note!
The automatic system can be operated very easily by using the familiar buttons as with all previous models
and without menu navigation.

5. Warnings
5.1. Regulations and instructions
1. Applicable regulations, especially those of the VDE must be observed.
2. The information in the service instructions must be complied with prior to commissioning.
3. The parameterisation of the unit must be carried out in such a way that endangerment of persons and
property is excluded.
5.2. Installation and commissioning
The installation and commissioning must only be carried out by sufficiently qualified personnel.
5.3. Connections
1. The connection of the unit must be carried out carefully, as a wrong connection could lead to the de-
struction of the unit. The connection regulations must be observed!
2. The PE(N) must be connected to the terminal 5 of X403.
3. The shields of the analogue signals must only be connected to the earthing screw next to terminal
strip X401
and otherwise no other connection to metal parts.
4. Converter connections k must be connected to the protective conductor.
5.4. Battery and supply voltage
5. If the battery has to be disconnected, the charging unit must be switched off.
6. The battery negative potential must be earthed at the input terminal on the switchboard. The mini-
mum cross-section is 10 mm2.
7. The supply voltage (12 or 24 V DC) is selected using a switch located on the RZ-071-D.
8. If the supply voltage of the automatic system was switched off, it must only be switched on again after
approx. 20 seconds.
9. The leakage current of the noise filter upon a 2-phase voltage loss is 22 mA.
5.5. Coils
All the coils must be provided with a freewheeling diode (for DC voltage) or with a quench circuit matching
the inductance of the coil. This also applies for all relays and inductances that are used in the switchgear or
are externally activated.

6. Basic operation of automatic system
The automatic system can be operated very easily, as with all previous models and without menu navigation.
The operating mode can be selected using four buttons. In MANUAL and TEST mode, the generator is switched
on and off using the buttons arranged in the mimic diagram.
In MANUAL mode, the START button is programmed for a manual start. The LED TEST and ALARM OFF buttons
are self-explanatory.
During normal operation, the display is only required to display pending alarms and the actual values. The
menu is also easy to use here: Use the [→] and [←] keys to select the required group (alarms or actual val-
ues) and use the [↑] and [↓] keys to display the required actual value or pending alarms.
6.1. Operation of the display
You select a parameter or a value just like you read a book. The different groups are saved as 'pages'. The
groups can be scrolled through forwards and backwards using the [→] and [←] cursor keys. Within a group,
they are read like 'lines' of a text from top to bottom. The lines are selected by pressing the cursor buttons [↓]
(down) and [↑] (up). If the ‘end of the page’ is reached, it starts again from the top or the bottom.
By holding the LED TEST key and pressing the [←] key, the ACTUAL VALUES group is directly selected; by
holding LED TEST and pressing the [→] key, the display of alarms is directly selected.
To change a parameter, first enter the valid ID number. A Group 0 parameter, -GENERAL PARAMETERS-, can
be changed without entering a valid ID number. A parameter is changed as described above.
1. Select the group of the desired parameters with the [←] and [→] buttons.
2. The display with the required parameter is selected using the [↑] or [↓] key. A maximum of two parameters
are displayed.
3. Press the OFF and LED TEST buttons (function PARA ON or PARA OFF) at the same time. The parameteri-
sation mode is initiated and is indicated by the solid cursor [ █ ]. It is no longer possible to change the
group.
4. The required parameter is selected with the [↑] or [↓] key.
5. By simultaneously pressing OFF and ALARM OFF (ENTER function), the displayed line is defined, which is
indicated by the cursor shape that now displays the parameter position to be changed by an underscore [
_]. The line may no longer deselected.
6. The parameter position to be changed is selected using the [←] and [→] cursor buttons and a numeric
parameter is increased or decreased by 1 using the [↑] and [↓] buttons. A parameter that is displayed by a
letter (prefix, alarm coding), is changed using these buttons in reverse order.
7. The displayed parameter is applied by simultaneously pressing Off and Alarm off.
If you want to cancel the parameterisation step, simultaneously press the Off and LED Test buttons instead
of OFF and ALARM OFF.
6.2. Display contrast setting
The display contrast is increased by holding the LED TEST button and pressing the [↑] button (display becomes
darker) or decreased by holding the [↓] button (display becomes brighter).

6.3. Parameterisation
6.3.1. Description
The parameterisation is described in the SERVICE MANUAL. The parameterisation of the basic settings, group
0, is explained in the following. These parameters can be changed without an ID number. Group 0 is se-
lected using the [←] and [→] keys.
6.3.2. General parameters, group 0
The parameters of this group can be changed without a valid ID number.

In normal operation it is useful to use the [←] and [→] buttons between the display
of actual values and the current alarm signals. Parameter groups are skipped over
in normal operation if this parameter is set to [-], so only one key strike changes be-
tween ACTUAL VALUES and CURRENT ALARMS.
Enter a [+] if you want to change a parameter to view the parameter groups.
Irrespective of this setting, you can always press LED TEST and [←] to go direct to

7.1. Monitoring on
This green display (after the genset start-up) signals the release of the operating-dependent delayed alarms.
As soon as the motor has started up, this display flashes until the monitoring is enabled. The display goes
out at the beginning of the shut-down process.
7.2. Automatic system locked
This red display illuminates if an alarm to be switched off has elapsed or the external quick stop was actu-
ated. In order to unlock the system, the Off operating mode must be selected. If the signal cannot be cleared
even in Off, the external quick stop is still active.
7.3. Start control
The message will be activated as soon as a start request is present in automatic mode or if manual or test
mode has been selected. The display flashes as long as there is no start release. The display goes out as
soon as the genset exceeds the ignition speed during start-up (recognised from the D+ signal of the genera-
tor or from the revolution transmitter signal). Switching on the starter is then inhibited, even if attempted man-
ually. The starting generator voltage interrupts the start but does not cause the start control indicator to extin-
guish.

7.4. Fault
This yellow indicator flashes and the horn sounds once a new alarm occurs. Only the horn signal is acknowl-
edged using the Alarm Off key. The display automatically shows the page with the actual alarms.
If there are multiple alarms pending at the same time, the alarm to be acknowledged is selected using the [↑]
and [↓] cursor keys. For identification purposes, 'New' at the start of the line stands for an unacknowledged
or 'ACKN' for an already acknowledged alarm.
The yellow indicator lights up permanently once all alarms are acknowledged and goes out after all alarms
are cleared.
7.5. Four programmable displays
The functions of the four indicators of the right row are programmable within broad limits. You can display
selected, important alarms or used them as operating messages. Despite the direct display, alarms are also
shown on the display.
In addition, each of the 29 digital inputs can be used as an input for an parametrised operating message.
7.6. Mimic diagram / Voltage monitor
The mimic diagram displays the generator and the busbar. The position of the generator circuit breaker is
indicated through the green display underneath the keys. Four red and two green indicators are provided for
monitoring the generator voltage. They show whether the voltage is in the nominal range or whether and
which deviations are present. These indicators arranged under the generator symbol signal:
f <
f >
U <
U >
The green indicators signal that the monitored functions of voltage and frequency are within the tolerances.
The red LEDs only indicate a voltage error if the respective function is enabled for monitoring
All functions (U<, U>, f<, f>) and the response values of the voltage monitors can be parametrised. The UN-
DERVOLTAGE display also appears if the measuring voltage is connected with a left rotation field or if the volt-
age has too large an asymmetry of the vectors.
If an enabled monitoring signals a deviation from the nominal range, the respective red indicator flashes.
Both green indicators remain switched on for the duration of the drop-out delay of the monitor output. After
the delay expires, they go out and the red indicator illuminates continuously. The function is now processed
internally.
As soon as the voltage and frequency values are within the tolerance range again, the red display goes out
immediately and a release delay time is started. During this time, both green indicators flash that start illumi-
nating continuously when the time has expired. The voltage is then recognised internally as ‘good’.
The indicators are switched off if the OFF operating mode is selected or if there is no start command pending
in automatic operation.
Tasten für Betriebsart
Durch Betätigen der Tasten OFF, MANUAL, AUTO oder TEST wird die entsprechende Betriebsart angewählt. Die
Umwahl kann (über einen Eingang am Relaiszusatz) durch einen Schlüsselschalter blockiert sein.
Die Drehzahl kann in den Betriebsarten MANUEL und TEST von Hand eingestellt werden. Dazu ist unter IST-
WERTE die Drehzahl anzuzeigen und die Taste MANUEL bzw. TEST gedrückt zu halten. Mit den Cursortasten
[↑] bzw. [↓] kann dann das Drehzahlsignal zur Maschine angehoben bzw. abgesenkt werden.
7.7. Keys for operating mode
The respective operating mode is selected by actuating the OFF, MANUAL, AUTO or TEST keys. The selection
can be blocked by a key switch (via an input on the additional relay unit).
The speed can be manually set in the MANUAL and TEST operating modes. To do so, the generator voltage
must be displayed under ACTUAL VALUES and the MANUAL or TEST key must be kept pressed. The speed signal
for the machine can be increased or decreased with the[↑] or [↓] cursor keys.
7.8. Start key
The motor can be started in manualoperating mode by actuating this button. If the start program for a gas
motor is parametrised, the start sequence is processed accordingly. If the motor needs to be preheated, the
pre-heating device must be externally controlled. Actuating this key is ineffective when the machine is run-
ning or also in any other selected operating mode.

7.9. LED Test button
The functioning of all LEDs of the automatic system can be tested by this button. It is also used as a multi-
function button when parametrising and for the contrast setting.
7.10. Alarm Off button
An actuation pulse from this key is used to switch off the acoustic signal issued by a new alarm. If you press
it a second time, the alarm is deleted if the alarm-triggering event is no longer pending. Additional functions
are described in the alarm messages document.
8. Operating modes
The operating modes are selected by four keys. The selected operating mode is signalled by the LED above
the key. The keys can be electrically locked by an input (e.g. by connection of an external key-operated con-
trol switch) so any unauthorised or random change of a defined operating mode is prevented. The operating
modes described below can be selected using the keys.
8.1. Controlling the auxiliary drives
Before each start (if parameterised), a relay with the Auxiliary drives on function picks up. The Start Control
indicator flashes. If the start is released (e.g. gas tightness is checked, exhaust flap open, lubricating pres-
sure is reached), feedback must be provided. The flashing Start Control indicator lights up permanently after
the start release is issued (when the machine is at a standstill) and the engine can be started.
If no start release is required, the input must be permanently connected with the negative potential.
as otherwise no start is carried out.
8.2. Off operating mode
The Off position is automatically selected (reset function) during the application of battery voltage in order to
prevent the triggering of an unintentional start-up. When switching to Off from another operating mode:
a genset operation is immediately ended
Previously displayed alarms, except fault messages 13 and 14, are deleted as long as the respective
alarm contact is still active
The automatic system is unlocked, even if there is no signal on the quick stop input (emergency stop).
8.3. Manual operating mode
8.3.1. Description
After selecting the MANUALoperating mode, any auxiliary drives are switched on and, after start enable car-
ried out, the motor can be started with the START key. If the generator voltage is within the parametrised
nominal values and no alarm that switches off the generator is pending, genset operation can be switched to
with the Gen. On key (I). The generator is switched off after actuating the Gen. Off key (O).
The actuation of the On key remains ineffective if the generator voltage does not lie within the specified lim-
its. An external start order does not lead to the automatic switch-on of the generator.
In order to switch off the genset, the Off or (if the automatic start is not present) Automatic operating mode
must be selected.
8.3.2. Manual speed adjustment
The speed can be manually set in the MANUAL and TEST operating modes. To do so, the generator voltage
must be displayed under ACTUAL VALUES and the MANUAL or TEST key must be kept pressed. The speed sig-
nal for the machine can be increased or decreased with the [ ↑ ] or [ ↓ ] cursor keys.
8.3.3. Manual voltage adjustment
The voltage can be set manually. To do so, the generator voltage must be displayed under actual values and
the Manual or Test key must be kept pressed. The control voltage for the generator voltage controller can be
increased or decreased with the [ ↑ ] or [ ↓ ] cursor keys.

8.4. Auto operating mode
8.4.1. Description
For an automatic start (using the remote start command ), any auxiliary drives are switched on and the para-
metrised start program is triggered after the start function is enabled. If the genset has not started at the end
of the start program, the failed start alarm is issued and the automatic system inhibited.
After the genset has started up, the generator is switched on as soon as the nominal generator voltage and
frequency are reached.
After removing the start command, the delay time is switched (switch-off delay). The generator is switched
off then. To avoid heat accumulation, the genset switches the generator off, continues to run without load for
the set run-on time and is then shut down.
8.4.2. External start order
The start can be enabled using two remote start commands :
Start with switching (remote start WITH load transfer) (terminal 18)
Start without switching (remote start WITHOUT load transfer) (terminal 25)
Sprinkler requirement (terminal 23).
For an automatic start with a generator switch-on, the genset starts up and switches to generator operation.
The generator will be switched off equally after deactivating the remote start.
The Input Start without switching on is provided for e.g. supply voltage sensitive consumers. For providing
e.g. a fast availability for supplying power, the genset can be started via this input. Only the starting program
runs down, no generator connection takes place. If a remote starting command with generator switch-on is
given, generator connection takes place.
8.5. Test operating mode
After selecting the test position, any auxiliary drives are switched on and the parametrised start program is
triggered after the start function is enabled. If the generator voltage with its voltage and frequency values are
within the nominal ranges, generator operation can be switched on using the GEN.-ON(I) key resp. switched
off using the GEN.-AUS (O)arranged in the mimic diagram.
If a remote start command with switching occurs during test operation, the system switches to generator op-
eration. In these cases, it is no longer possible to switch off the generator circuit breaker manually.
In order to switch off the genset, the Off or (if the automatic start is not present) Automatic operating mode
must be selected.
9. Sprinkler operation
The following functions are intended for the operation of an electrical sprinkler pump:
Switching over of all alarms to be switched off to warning
Start program with 10 (parametrisable) start attempts
for the duration of the start-up time of the sprinkler pump in accordance with the parameterisation switch-
off of the emergency power consumers or no interruption of the emergency supply.
For ending the sprinkler requirements in accordance with the parameterisation:
Cancellation of sprinkler operation after the SPRINKLER RUN-ON TIME or only manually switched off
The time stage for sprinkler operation run-on time can be set in the range 10 to 2400 seconds. If it is para-
metrised to 0 sec., the genset does not automatically switch off.
In this case, the display of the Off operating mode flashes.
The genset can then only be stopped by the quick stop or Off operating mode.
The interruption of the emergency current operation for the switching on of the sprinkler pump can be para-
metrised in the range 0 to 24 sec. For the 0 sec. setting, there is no switching-off of the consumers. The
switching-off of the consumers begins with the sprinkler operation signal.
If the sprinkler requirement is met, the emergency power consumers are also switched on during a power
failure or remote start. For return of the power or after removal of the remote start command, the emergency
power consumers are switched back to the mains after the switch-back delay.
Switching off the generator or shutting it down due to an alarm is suppressed. However, if a switch-off alarm
occurs, the collective switch-off alarm is output.
